Megumi Okada was born on April 4, 2002, in Aichi Prefecture, Japan.
Her given name is written with the single kanji 愛.
In her case, the name is read Megumi, not Ai.
This distinction matters because online searches for 岡田愛 frequently combine her with unrelated Japanese professionals whose names use the same characters but are read Ai Okada.
Megumi's public career began through a magazine-linked audition.
Ciao Girl 2012 Audition In August 2012, Megumi entered the Ciao Girl 2012 Audition held as part of Ciao Summer Festival.
She received the Grand Prix.
Contemporary and later accounts also credit her with the Nico☆Puchi Award connected with the same selection.
Sara Kurashima and Momo Kobayashi received Semi-Grand Prix recognition that year.
Megumi, Sara and Momo subsequently became affiliated with Amuse.
Winning the audition placed Megumi in the child-model and magazine-promotion environment surrounding Shogakukan's Ciao brand. She appeared in Ciao and participated in work associated with the Ciao Girl identity before Sakura Gakuin.
The audition is the correct starting point for her Amuse career.
It should not be backdated to her 2014 Sakura Gakuin transfer.
Early modeling and television work Megumi's early credits were small but established experience in more than one field.
In 2013, she worked as a still model for Studio Alice.
In January 2014, she appeared on TV Tokyo's Piramekino 640.
Her youth profiles listed ballet as a special skill.
These credits show that she entered Sakura Gakuin with some familiarity with cameras, posing and children's television, even though she was new to the group's demanding combination of singing, dancing, live talk and annual school-year storytelling.
Sakura Gakuin — transfer in the 2014 school year Megumi transferred into Sakura Gakuin on May 5, 2014, at the 2014 Transfer Ceremony at Meguro Persimmon Hall.
She entered with Sara Kurashima.
Sara was a first-year junior-high-school student.
Megumi was a sixth-grade elementary-school student and the youngest member of the new twelve-member lineup.
The two had already been connected through the 2012 Ciao Girl Audition, but their positions inside Sakura Gakuin were different because Sara was one school grade above Megumi.
The 2014 Student Council was led by: Moa Kikuchi — Student Council President Yui Mizuno — Produce Chairperson Hana Taguchi — Spirit Chairperson Yunano Notsu — Talk Chairperson
The other continuing members were Rinon Isono, Saki Ooga, Saki Shirai and Aiko Yamaide.
Megumi and Sara completed the lineup as the two transfer students.
Sakura Gakuin operated as a growth-period-limited group. Members left when they completed junior high school, and every school year reorganized seniority, responsibilities, songs and club activities around that rule.
Megumi therefore entered a group already preparing for an unusually consequential graduation: Moa, Yui, Hana and Yunano were all in their final year.
Her first months required her to find a place within a lineup containing four experienced graduating seniors and several members who had already spent multiple years together.
2014 Sakurademy acting award An early sign of Megumi's individual performance ability came at Sakura Gakuin Festival 2014.
The event included the recurring acting competition generally called the Sakurademy Actress Award.
Members improvised short scenes from an assigned situation.
During the second day's competition, Hana Taguchi, Rinon Isono, Saki Ooga, Saki Shirai and Megumi performed around the theme of confessing feelings at a senior's graduation ceremony.
Graduate Ayaka Miyoshi participated by voice as the rival school's Madonna.
Although Megumi was the youngest member and was attempting the segment for the first time, she won the top acting award.
Contemporary reports emphasized the contrast between her new-transfer position and the confidence of her performance.
The result is important in retrospect because Megumi's later work included acting in television dramas, but it should not be inflated into a professional acting prize. It was an internal Sakura Gakuin festival competition designed to test improvisation, expression and audience engagement.
First annual album and senior graduation Megumi participated in Sakura Gakuin 2014 Nendo ~Kimi ni Todoke~, released on March 25, 2015.
The album documented her first and only elementary-school year in the group.
On March 29, 2015, Moa Kikuchi, Yui Mizuno, Hana Taguchi and Yunano Notsu graduated.
For Megumi, their departure ended the period in which she could remain primarily the youngest newcomer.
She entered junior high school and became responsible for helping the next transfers adapt.
Sakura Gakuin — 2015 school year and LOGICA? Ver.1.2 The 2015 school year brought one of the largest transfer classes in Sakura Gakuin history.
Six new members joined: Maaya Asou Marin Hidaka Kano Fujihira Soyoka Yoshida Momoko Okazaki Mirena Kurosawa
Rinon Isono became Student Council President.
Saki Ooga became Education Chairperson.
Saki Shirai became Talk Chairperson.
Megumi was now a first-year junior-high-school student with one full Sakura Gakuin year behind her.
The scale of the transfer class changed the internal balance. Half of the twelve-member group was new, making the continuing members important bridges between the graduating seniors and the new members.
Science Club — LOGICA? Ver.1.2 During the 2015 school year, Sakura Gakuin revived its Science Club, Scientific Investigation Organization LOGICA?.
The Ver.1.2 lineup consisted of: Rinon Isono — RiNon / Isono researcher Sara Kurashima — SaRA / Kurashima researcher Megumi Okada — Mg3 / Okada researcher
The naming convention blended scientific language, stage aliases and wordplay.
Megumi's Mg3 identifier treated the first part of her name as the chemical symbol Mg and added a number.
The lineup re-recorded “Science Girl ▽ Silence Boy” for Sakura Gakuin 2015 Nendo ~Kirameki no Shizuku~, released on March 3, 2016.
The recording gave the revived unit a direct link to the original LOGICA? song while clearly marking a new generation of members.
This distinction is necessary because the original LOGICA? releases began in 2012, before Megumi joined Sakura Gakuin.
She should be credited for the Ver.1.2 recording and performances, not retrospectively attached to the original Ver.1.0 studio lineup.
The 2015 school year ended with the graduation of Rinon Isono, Saki Ooga and Saki Shirai on March 27, 2016.
Rinon's graduation required another LOGICA? reorganization.
Sakura Gakuin — 2016 school year and LOGICA? Ver.2.0 Sakura Gakuin began the 2016 school year at its May 6 Transfer Ceremony.
Three members transferred in: Tsugumi Aritomo Yuzumi Shintani Momoe Mori
Sara Kurashima became Student Council President.
Aiko Yamaide became Vice President.
Mirena Kurosawa became MC Chairperson.
Megumi entered her second year of junior high school.
She did not hold a council title that year, but she belonged to the senior half of the group and was one of the members expected to support Sara, Aiko and Mirena while preparing for her own final year.
LOGICA? Ver.2.0 The Science Club changed from Ver.1.2 to Ver.2.0 after Rinon graduated.
The new lineup consisted of: Megumi Okada — Okada researcher Sara Kurashima — Kurashima researcher Momoko Okazaki — Okazaki researcher
Momoko replaced Rinon.
The unit recorded the new song “Delta.”
“Delta” was written, composed and arranged by EHAMIC and appeared on Sakura Gakuin 2016 Nendo ~Yakusoku~, released on March 3, 2017.
The song's electronic structure, rapid phrasing and scientific vocabulary continued the conceptual identity of LOGICA? while giving the 2016 configuration its own studio recording.
Megumi is therefore documented in two official Science Club versions: Ver.1.2 in the 2015 school year, and Ver.2.0 in the 2016 school year.
Her club activity is sometimes mistakenly extended into the 2017 school year simply because she remained in Sakura Gakuin until March 2018.
The official Science Club lineups and album chronology place her active LOGICA? period in the 2015 and 2016 school years.
Shuoh Gakuen Gasshoubu Megumi also participated in Sakura Gakuin's 2016 stage production Shuoh Gakuen Gasshoubu.
The musical-theater project placed Sakura Gakuin members in an ensemble story centered on a school choir and required a different type of rehearsal from the group's normal concerts.
Megumi was unavailable for the August 31, September 1 and September 2 performances because of academic advancement and entrance-examination mock tests.
Nanako Kurosaki substituted for her on those dates.
Megumi participated in the other scheduled performances.
Accessible official production information does not provide a reliably attributable named character for her. This profile therefore records her participation without inventing a role name.
The conflict between stage dates and entrance-examination preparation also illustrates a recurring feature of Sakura Gakuin: entertainment activity had to coexist with the real educational transitions that determined membership.
History, castles and the Sakura Gakuin diary Megumi's interest in Japanese history became one of her clearest individual themes.
She was especially associated with castles, the Sengoku period and historical figures.
In Sakura Gakuin's official diary, she developed entries under the title Megumegu no O-shiro Tanbou, meaning Megumegu's Castle Exploration.
Published installments covered locations including Nagoya Castle, Gifu Castle and Matsumoto Castle.
The series was more than a one-line profile hobby.
It required her to visit sites, observe architectural and historical details, organize information and communicate it in her own written voice.
Her history interest later appeared in television work and ultimately in university education.
This produces one of the strongest long-term lines in her biography: childhood curiosity about castles, public diary writing inside Sakura Gakuin, history-focused television appearances, and a university degree in history.
It would nevertheless be speculative to assign a specific university specialization or graduation-thesis subject unless Megumi publicly identifies it.
Sakura Gakuin — 2017 school year and Talk Chairperson The 2017 Transfer Ceremony took place on May 7, 2017.
Miku Tanaka and Miki Yagi joined the group.
The Student Council became: Aiko Yamaide — Student Council President Megumi Okada — Talk Chairperson Momoko Okazaki — Ganbare!! Chairperson Maaya Asou — Education Chairperson
Megumi became Sakura Gakuin's fourth Talk Chairperson.
Earlier positions connected with talk or MC leadership had been held by Yunano Notsu, Saki Shirai and Mirena Kurosawa.
At the appointment ceremony, Megumi explained that what she had learned from the previous Talk and MC chairpersons was that the most important part of talk was communicating and delivering one's feelings.
She acknowledged that she had less talk experience and had sometimes lacked confidence.
Her aim was therefore not only to become louder or dominate conversations. She wanted to improve her own speaking and think about themes and structures that would help each member produce a story appropriate to her personality.
That objective matched the educational concept of the council title.
A Talk Chairperson was not simply a permanent master of ceremonies. The office required the holder to help the entire group communicate more clearly in live talk, interviews, diary writing and variety-style segments.
Megumi's appointment also had a visible connection with her external work later that year.
Oha Girl — beginning during Sakura Gakuin's final year On October 6, 2017, Megumi was announced as one of five new Oha Girls for TV Tokyo's children's morning program Oha Suta.
She began as the Monday Oha Girl on October 9.
The weekday lineup was: Monday — Megumi Okada Tuesday — Musubu Funaki Wednesday — Sakura Inoue Thursday — Kurumi Miyata Friday — Satsuki Okumori
Oha Suta was a live early-morning production built around children's news, games, product features, challenges, guests and energetic presentation.
Megumi was introduced in contemporary coverage as the history-and-castle-loving Monday member and as Sakura Gakuin's fourth Talk Chairperson.
The assignment gave practical daily-broadcast meaning to the communication goals she had stated at the beginning of the school year.
It also made her final Sakura Gakuin year logistically difficult.
The three graduating members were pursuing different individual directions: Aiko was developing piano-and-vocal singer-songwriter work, Momoko was preparing for overseas study, and Megumi was balancing regular morning television with school and group rehearsals.
In the graduating-class interview, the three explained that the full twelve-member lineup was often unable to rehearse together.
Megumi said that communication after lessons increased because members needed to prepare for and support those who had been absent.
Words, reporting and future ambition By the end of the 2017 school year, Megumi connected her Talk Chairperson experience with a broader professional goal.
She explained that writing Sakura Gakuin diary entries from sixth grade onward had taught her the power of words.
She said that she wanted a future job such as newscaster or reporter in which she could use words to communicate events to people in real time.
At the graduation ceremony, contemporary reporting summarized her ambition as becoming a news presenter.
Her later career did not develop into a permanent newsroom post, but several of her documented credits followed the same direction: live children's television, history-program participation, field reporting, interview-oriented presentation, and a short monthly-MC assignment.
The ambition should therefore be described as a stated graduation-era goal and a meaningful career theme, not as a profession she ultimately held on a continuing basis.
My Road and the graduating trio Sakura Gakuin 2017 Nendo ~My Road~ was released on March 3, 2018.
The album included “Mirai Tokei,” performed by the three graduating members: Aiko Yamaide, Megumi Okada, and Momoko Okazaki.
The performance imagined the trio through the image of clock hands moving toward the future.
It belonged to the graduating class as a group and should not be listed as a Megumi solo song.
The same album documented Megumi's final main-group year and her Talk Chairperson period.
Graduation — March 24, 2018 Megumi graduated from Sakura Gakuin at The Road to Graduation 2017 Final on March 24, 2018.
The concert took place at Nakano Sunplaza before approximately 2,200 spectators.
She graduated with Aiko Yamaide and Momoko Okazaki.
The performance included “Mirai Tokei,” the formal certificate ceremony and the traditional closing songs.
In her final address, Megumi thanked the fans who had supported her across four years and said that she was glad to have been in Sakura Gakuin.
The headmaster and homeroom teacher framed the ceremony around the different routes being taken by the three graduates: music for Aiko, communication and news presentation for Megumi and overseas language study for Momoko.
Megumi's exact Sakura Gakuin membership ran from May 5, 2014, through March 24, 2018.
Counting both the first and last calendar dates, the span was 1,420 days.
Her formal club record during those years was LOGICA?.
She was not a member of Twinklestars, Mini-Pati, the Purchasing Club or BABYMETAL.
Graduation photo book and delayed handover event The 2017 graduating class received an official photo book photographed on Oshima and released in March 2018.
The planned handover events did not proceed identically for all three graduates.
Megumi was absent from the March 31 event because of illness.
Aiko and Momoko appeared on that date without her.
A replacement Megumi event was held on April 14, 2018.
She attended alone and publicly thanked Aiko and Momoko for carrying the earlier session.
The rescheduled event became her immediate post-graduation farewell connection with the Sakura Gakuin audience.
It should not be confused with a delayed graduation date. Her membership still ended at the March 24 ceremony.
Oha Girl after Sakura Gakuin Megumi continued on Oha Suta after leaving Sakura Gakuin.
This post-graduation year is sometimes omitted when short profiles stop her Oha Girl period in 2018.
Her actual regular assignment continued until March 18, 2019.
Across approximately seventeen months, the role required early live-broadcast energy, concise delivery, participation in location and studio segments and interaction with presenters, guests and young viewers.
The regular Oha Girls were announced as graduating together in March 2019, with one weekday member receiving a farewell on each day's broadcast.
Megumi's Monday graduation episode aired on March 18.
She wrote afterward that she had graduated from Oha Suta and was overwhelmed with emotion.
The program remained a strong part of her public identity. Years later, her social profile still described her first as a former Oha Girl.
Selected post-Sakura Gakuin television work — 2018 and 2019 Megumi's work after March 2018 did not follow only one category.
On July 29, 2018, she appeared on Fuji TV's Wide na Show in the youth-commentator position then described as a current high-school participant.
The appearance extended the talk and opinion side of her profile beyond children's television.
In 2019, her history interest became increasingly visible on television.
On May 14, she appeared in the castle-themed episode of NHK ETV's Numa ni Hamatte Kiite Mita.
The episode explored the fascination of attacking and understanding castles across time.
Megumi participated as a young castle enthusiast rather than as an academic expert.
She also appeared in a Kumamoto Castle installment of Himitsu no Treasure Eizou Gallery on BS-TBS, alongside castle specialist Yoshihiro Senda and other presenters.
The production used visual material and virtual-reality reconstruction to explore parts of Kumamoto Castle.
On October 15, 2019, Megumi participated in TBS's Quiz! Only 1 in the Sengoku-warlord category.
The participant group included established history communicators, performers and enthusiasts.
Her presence in that field was a natural extension of the castle diaries that had begun during Sakura Gakuin.
These appearances should not be rewritten as proof that she was already a professional historian. At the time, she was a young entertainer with a documented specialist interest.
The later history degree gave the interest academic continuity, but it did not retroactively change the capacity in which she appeared on the earlier programs.
2020 — reduced public activity and Oha Suta return The COVID-19 period interrupted the normal entertainment and educational environment.
Megumi's publicly documented work became less frequent than during the Oha Girl years.
She made a return appearance connected with Oha Suta in September 2020.
Such later appearances belong to her relationship with the program as a former Oha Girl and should be separated from the October 2017–March 2019 regular contract period.
2021 — university and acting credits Megumi entered Sophia University in April 2021 and studied in the Faculty of Humanities, Department of History.
The university name and department were publicly confirmed by Megumi when she announced her graduation in 2025.
Her four years of study overlapped the final two years of her Amuse affiliation.
She continued to accept selected entertainment work while studying.
On August 16, 2021, she appeared in a reenactment segment of Fuji TV's Tsukai TV Sukatto Japan, credited as Sara Yamashita.
On September 5, she made a small appearance in episode ten of TBS's TOKYO MER ~Hashiru Kinkyuukyuumeishitsu~ as one of the students at Kanto Medical University.
The role was an ensemble television-drama credit, not a lead or recurring part.
She also participated in Amuse digital content, including a 2021 summer greeting video.
March 2021 brought another Sakura Gakuin connection through the publication Thank you… .
The tenth-anniversary book collected messages from the full body of Sakura Gakuin graduates.
Megumi's contribution was an official alumni record rather than a live reunion.
2022 — drama, Oha Suta anniversary and reporting Megumi's 2022 work showed the same mixture of acting and communication-oriented assignments.
On June 19, she appeared in the fifth television series of The Files of Young Kindaichi, in the episode adapting the Headless Samurai / Kubikari Musha case.
She portrayed the high-school-era version of Ayako Tatsumi, the deceased first wife in the story's family history.
The part was limited but identifiable, unlike some of her unnamed ensemble appearances.
In September, she participated in Oha Suta's twenty-fifth-anniversary period through recorded material and guest appearances associated with former Oha Girls.
The reunion should not be counted as a return to the regular Monday post.
Her strongest presenting credit of the year came through the National Barber and Beauty Student Skills Competition, commonly called Ribiyo Koshien.
Megumi was announced as the event's passion reporter for the November 1 national competition.
She later served as reporter in the BS TV Tokyo special Ribiyo Koshien 2022 ~Mirai e no Kakehashi~, broadcast on December 25.
The program followed students training in barbering and beauty techniques and documented the emotional and technical pressure of the national event.
This was a clear professional reporting assignment and one of the closest later credits to the real-time communicator role she had imagined at Sakura Gakuin graduation.
2023 — final Amuse work At the beginning of 2023, Megumi served with Hinako Kikuchi as a January monthly MC for ABC Asahi Broadcasting's Hatache! ~Trend Otameshi-bu~.
The first January installment aired on January 5.
She also appeared in episodes three and four of the Yomiuri TV / Nippon TV drama Shoumona Bokura no Renairon, broadcast on February 2 and 9.
These were among her last documented screen credits while affiliated with Amuse.
Departure from Amuse — March 2023 On March 10, 2023, Megumi announced that she would leave Amuse at the end of that month.
The departure became effective on March 31.
She described her experiences at Amuse as irreplaceable and treasure-like and expressed gratitude for the support she had received.
The departure closed an agency relationship that had begun after the 2012 Ciao Girl Audition.
It also marked the end of her documented regular entertainment career to that point.
The wording should be handled carefully.
Megumi announced departure from Amuse.
She did not publish an explicit statement saying that she was permanently retiring and would never again appear publicly.
Later events confirm that complete disappearance would be an inaccurate description: she retained X, shared public updates and appeared at an alumni event in 2026.
At the same time, no new agency, continuing acting career or regular professional entertainment schedule has been verified after March 2023.
The balanced classification is therefore: former entertainer who left her agency, completed university and entered company employment, while retaining occasional public and alumni visibility.
University studies and transition to employment Megumi spent four academic years in Sophia University's Department of History.
In a November 2024 public update, she said that she had completed her employment-offer ceremony in October.
She explained that the new field was completely different from her previous world and that she had obtained work she had wanted to attempt since her third university year.
At the time, she was struggling with her graduation thesis.
The statement is useful because it confirms deliberate preparation for a non-entertainment career.
It does not identify the employer, industry, position or thesis subject.
Those details should remain unassigned.
On March 31, 2025, Megumi publicly announced that she had graduated from Sophia University's Faculty of Humanities, Department of History.
She wrote that the four years had required her to confront the difficulty of turning something she loved into an academic subject.
That sentence gives the most direct account of how her longstanding history interest changed at university.
Enjoying castles as a child and researching history academically were not the same experience.
Her comment acknowledged the rigor and difficulty involved in making that transition.
In April 2025, Megumi became a new company employee.
Later in September she said publicly that she was doing well as a working member of society.
Her X biography continued to identify her as a former Oha Girl and company employee.
No reliable public source identifies her employer.
No attempt should be made to derive the company or profession from photographs, social contacts, the location of her university or her history degree.
Sara Kurashima reunion — February 2025 In February 2025, Megumi shared photographs from meeting Sara Kurashima.
She said that she had seen Sara again after a long interval and that the two had drunk highballs together.
The reunion had particular historical significance because Sara and Megumi had been connected twice at the beginning of their careers: through the 2012 Ciao Girl Audition, and as Sakura Gakuin's two 2014 transfer students.
The post documented an adult friendship and alumni connection.
It was not a joint professional project, promotional campaign or formal Sakura Gakuin event.
Raura Iida 28th Birthday Event — April 2026 Megumi's most important verified post-employment public appearance occurred on April 12, 2026.
She was a guest at Raura Iida's 28th Birthday Event at HYPERMIX Monzen-nakacho in Tokyo.
The publicly announced participants were: Raura Iida Ayami Muto Yunano Notsu Megumi Okada Mori Hayashi as MC
Megumi and Yunano were scheduled for the first and second parts.
Ayami participated across all three parts.
The configuration created a substantial Sakura Gakuin reunion around Raura, combining graduates from different school years with the group's longtime homeroom teacher.
Megumi participated in talk and game segments and interacted directly with the audience.
Afterward, she thanked Raura for inviting her and expressed happiness at seeing Mori, her seniors and Sakura Gakuin fans again after the years since graduation.
This event proves that company employment did not prevent every public appearance.
It does not prove a full entertainment comeback.
There was no accompanying agency announcement, new acting contract, music release or regular schedule.
It is best classified as a verified guest appearance by a Sakura Gakuin alumna.

Credit limitation The official club page lists repertoire across the complete LOGICA? history.
Not every listed studio recording includes Megumi.
The original LOGICA? Ver.1.0 began in 2012 with Marina Horiuchi, Hinata Sato and Rinon Isono, before Megumi entered Sakura Gakuin.
Megumi's securely documented studio contributions are the Ver.1.2 re-recording of “Science Girl ▽ Silence Boy” and the Ver.2.0 song “Delta.”
Live performances of inherited repertoire should be described as performances when a set list confirms them, not automatically converted into original-recording credits.
Not a member — Baton Club Twinklestars Megumi was not a member of Twinklestars.
The 2014 lineup included Yunano Notsu, Yui Mizuno, Aiko Yamaide, Sara Kurashima and Moa Kikuchi.
Sara's presence can cause confusion because she and Megumi transferred together, but only Sara joined the Baton Club that year.
Not a member — Cooking Club Mini-Pati Megumi was not a Mini-Pati member.
During her years in Sakura Gakuin, the unit involved the second-generation and third-generation lineups, neither of which included her.
Temporary performances and ensemble participation Participation in full-group concerts, shuffle material, public lessons or the Shuoh Gakuen stage production does not create an additional official club membership.
