Jpop group AKB48 has had their music in Taiko: Drum Master and a 3DS game. However, AKB48+Me from Kadokawa Games is more of an idol training game than a rhythm title. Strategy & Partners, the company that made Attack on Titan: Wings of Counterattack Online, also developed the official AKB48 music game aptly titled AKB48 Finally an Official Music Game Is Out.
This title is a rhythm game where you tap and flick the screen to hit notes while super deformed AKB48 members sing songs. Players can put together a group of their favorite AKB48 members and take the smartphone stage. As your rank goes up, you can unlock new stages and songs.
