Game based on franchise about hot spring guardian deities launched in August 2018
The official Twitter account for Onsen Musume: Yunohana Collection, the smartphone game based on the Onsen Musume franchise, announced on Thursday that the game will end service on September 30. The game launched in August 2018, and it had an animated trailer.
The Onsen Musume idol project features hot spring guardian deities who form an idol group. In the project's story, god of hot springs Sukunahiko summons nine girls to fight the decline of interest in hot springs. To fulfill their role, the Hot Spring Girls form the idol group SPRiNGS. The girls serve as guardian deities who are voiced by seiyū and designed individually by different character designers.
Enbound first announced the project in 2016. The multimedia project also includes manga, single CDs, and animated music videos. The franchise's idol group released the album Diversity internationally on January 7.
The project also has a male counterpart project titled Onsen Ninja.
