Minako is a Hasetsu native who was able to garner some amount of international fame for her skills in ballet, usually travelling around the world during her youth. She is one of the recipients of the Benois de la Danse, one of the ballet world's greatest honors.
Minako has since settled down in Hasetsu and started up a ballet studio, where she teaches local students. Currently, Yuuri is her only student, since in recent years less and less people have been coming to her for lessons due to Hasetsu's shrinking population. In addition to her ballet studio, Minako also owns and operates a snack bar called Kachu Snack Bar.
Minako has medium length brown hair that reaches past her shoulders, half down and half up in a short ponytail. She has dark grey eyes and a single mole under her left eye.
She is fairly tall, with long legs and the slim figure of a ballerina. She is usually seen wearing a brown trench coat over a blue-gray cardigan and a white blouse, with dark blue skinny jeans and brown ankle boots.
Minako is an energetic and outgoing person, often striking ballet poses whenever she gets enthusiastic about something. She insists on manners, discipline, and body management. She tries to keep Yuuri motivated as a skater, because the number of youth in Hasetsu is declining, putting her job as a ballet teacher in peril.
She enjoys alcohol which contradicts her emphasis on manners and causes her to be quite brash and loud. She constantly expresses her attraction towards the other skaters while drunk, especially to Victor. She is a very big fan of Christophe's, cheering for him when he performs and becoming flustered when noticed by him.
Minako is a friend of the Katsuki family, and is particularly close with Yuuri, as his former ballet teacher and long-time supporter. She is the one who encouraged him to go into figure skating, and often accompanies him on late night practice sessions either at her studio or at Ice Castle Hasetsu. Aside from the Rostelecom Cup, she goes to almost all of Yuuri's competitions so she can support him, though she also goes due to being a skating fan.
Minako and Hiroko are old friends, with Minako being on a first-name basis with Hiroko and often visiting Yu-topia. Hiroko refers to Minako with the "-senpai" honorific since the two of them went to school together at some point and Minako is older.
Minako gets along well with Mari, whom she refers to as "Mari-chan". They travel together to Barcelona so they can see the Grand Prix Final live.
Minako and the triplets are seen to have a decently close relationship, planning "Hot Springs on Ice" together and celebrating in a dance when putting up posters. She sits with them in the stands during the event.
- "Toshiya-san, this is no laughing matter! This is not the weight a figure skater should have!" (To Toshiya)
- "Yuuri was able to grow because he had a place where he could practice alone whenever he got anxious. He's no genius, but he was gifted with more free time than anyone else to practice." (to Victor)
- "I pulled an all-nighter to help Yuuri practice, and he's no ordinary pork cutlet bowl." (to herself)
- "Yuuri, you are known for your step-sequences and spins." (to herself)
- "I've never seen you wearing that ring before." (to Yuuri)

- Minako's official age has not been revealed, but it has been confirmed that Hiroko is younger than her. Since Hiroko is 49 years old, this would mean that Minako is at least 50.
