Tokyo 7th Sisters prepares its final encore after 12 years

Tokyo 7th Sisters, often shortened to t7s or Nanasis, is a Japanese idol rhythm and adventure mobile game that began service in 2014. It is trending because DONUTS announced that the game app will end service on August 12, 2026 at 14:59 JST, closing a roughly 12-year run for a title with long-running music, characters, events, and live fandom.

The first event was the official May 7 notice from DONUTS. The company said paid Seventh Coin sales stopped at 18:00 JST that day, that the app service will end on August 12, and that refund applications for unused paid currency will run from August 12 at 18:00 JST through November 30 at 23:59 JST. For players, that makes the announcement practical as well as emotional: they have to understand the end date, currency handling, and what to keep installed.

Fans are reacting because this is not just a game disappearing from a store. Tokyo 7th Sisters has functioned as an idol franchise, with songs, characters, live events, official broadcasts, goods, and years of player memory attached to it. The official notice also softened the blow by saying that an offline version is in development so users can keep access, as much as possible, to live stages, episodes, the sound player, and owned cards.

For non-Japanese readers, the context is that Japanese mobile idol games often become multimedia communities. A shutdown can feel closer to a franchise transition than a simple app closure. DONUTS says live events, goods, official streams, and official social channels will continue outside the app. What to watch next is the offline version, the final in-app update schedule, and whether the continuing live and music activity can keep Tokyo 7th Sisters visible after the app itself ends.
