— Tanaka Kotoha, Online Profile

Tanaka Kotoha (田中琴葉?) is a new idol introduced in THE iDOLM@STER: Million Live!. She is voiced by Taneda Risa.


Kotoha is a very diligent girl with a passion for acting, though she often gets lost in it when doing so. If one had to describe what Kotoha is like in three words, it would be “an honors student”; she's diligent, takes everything seriously, does all work to her absolute best, and she just seems to be perfect at everything. Yet, she actually has low self-confidence. She often says that she has no any real talents (except maybe acting), and she has a somewhat fragile mentality. This makes Kotoha easily pressured by her work and she accumulates a lot of emotional stress from time to time, to the point that she occasionally breaks into tears. For example, in the event “Idol Symphony”, where Kotoha had been made the leader of the wind instrument group, the responsibility and lack of self-confidence lead her to break into tears in front of Megumi, as she felt that Megumi was more suited to be leader than she was. Fortunately, in those times, her two best friends, Megumi and Elena (and of course, the Producer), are often there to comfort her.

However, work is not the only thing that gives her stress-- her feelings for the Producer also cause her a lot of stress. Because her lack of self-esteem, Kotoha is unable to confess her feelings, so she stresses herself out by trying to make herself look good in the Producer's eyes. This leads to many of her dialogues with the Producer sounding like she's going to break down in tears at any time. For example, in the Christmas event, when the Producer lent her his coat, she asked him whether he's only kind to her because she's an idol, and in the event “Idol Symphony” , when the Producer praised her and said that she's so good at her job that she’ll be fine even if he's not there, she became upset. She later confessed that she actually tried her best because she wanted the Producer to recognize and praise her, and he said that he needed Kotoha by his side. In conclusion, Kotoha is a diligent girl with confidence issues.

On her days off, she enjoys fencing, and seems to put all of her effort into it. Despite the fact that she has a mature air about her, one of her favorite things is ice cream.


In September 2016, Kotoha's voice actresses' agency announced that she would be taking a temporary leave from the industry due to an unspecified illness. As a result, Kotoha's role in THE IDOLM@STER THE@TER ACTIVITIES 03 was given to Yabuki Kana (who was the runner-up in the in-game election for that part), and she does not appear on the THE IDOLM@STER LIVE THE@TER FORWARD 03 Starlight Melody CD, though she is technically part of the in-game unit Scorpio alongside Arisa, Shiho, and Umi.

Kotoha does not appear in THE iDOLM@STER MILLION LIVE! THEATER DAYS‎, though she is confirmed through an announcement to be playable eventually.

Currently, if/when Taneda Risa will return to voice Kotoha is unknown; however, Taneda has been slowly returning to the industry.
