Amina started her career as a child actress, debuting in reenactment dramas on Japanese TV in 2000.
Growing up as an only child in Tokyo, she developed a love for performing at an early age.
Her experiences as a child actress laid a solid foundation for her later roles in entertainment.
Before joining AKB48, Amina was already an avid fan of the group, often attending handshake events — a true idol enthusiast even before she was on stage herself!
Amina’s entertainment journey began as a child actress with Maimu Pro.
She entered the idol world in 2007 after making it through the grueling AKB48 4th Generation audition.
Initially performing as a trainee, she quickly won a spot in their "Himawari Group" shows.
Her determination paid off in 2008 when she became a full-fledged member of Team A, and she tackled various positions as teams shuffled—Team B and later Team K—displaying impressive adaptability.
Amina's big break came during the first AKB48 general election, where she ranked eighth, a surprising achievement for someone with minimal media exposure.
Her theater performances were legendary; she memorized nearly all positions for every team, earning a reputation as the “Ace of the AKB Theater.”
From 2009, Amina dove into voice acting, debuting in the anime "Usaru-san" and later being cast as one of the main voices in the AKB0048 anime, portraying Yuka Ichijo.
She cemented her seiyuu credentials in roles like Otoha Nashida in "Triage X," Nanami Sakuragaoka in "Girlish Number," and, most notably, Arisu Tachibana in the massive hit "The Idolmaster: Cinderella Girls," also performing numerous character songs and live concerts.
After graduating from AKB48 in 2014, Amina joined Osawa Office, focusing on voice work in anime, games, foreign film dubbing, and radio.
Aside from anime, she has also appeared in dramas, on stage, and hosted her own popular radio shows such as "Amina Satou no Konoyo ni Komoji wa Irimasen!" and "Amina Satou no Amimen!"
Amina is longstandingly celebrated for her performance in the first AKB48 General Election, where she achieved a top-10 rank with 8th place, despite not being a center-stage regular.
She was chosen for the single "Iiwake Maybe," a feat that made her a symbol of the "Cinderella story" within idol culture.
She successfully transitioned into a respected voice actress, becoming a staple in "The Idolmaster: Cinderella Girls" franchise for more than a decade.
Her career is marked by versatility, from lead stage roles to regular appearances at anime music festivals like Animelo Summer Live.

She maintains good relationships with other former AKB48 and SKE48 members, often collaborating or supporting each other publicly.
In her personal life, Amina announced her marriage to a non-celebrity man in 2019.
Since then, she's occasionally shared glimpses of her married life, balancing it with her busy career.
Amina is a self-described idol fanatic and AKB48 super-fan—she joined the group because of her genuine love for their music and culture.
She has quirky hobbies like three-hour phone calls, making crafts from plastic boards, and going to karaoke or movies alone.
She’s known for using big characters in words that usually have smaller font—a unique writing style featured in her blog.
She’s candid about her personal journey, admitting struggles with confidence and self-promotion in her early career.
