What this is
Karaoke no Tetsujin — one of Japan's biggest karaoke chains — is running a full collaboration with the short anime "You've Lost Ritsuka Fujimaru" across participating stores nationwide from July 9 to August 16, 2026. Fans can order themed collaboration drinks and set menus, pick up original merchandise, and book specially decorated concept rooms at five locations: Akihabara, Osaka Namba, Matsuyama, Niigata, and Sapporo. Merchandise is also available through Animate Online Shop from August 6 to 23 for those who can't visit in person.
Who should go
Fans of the Fate/Grand Order universe and the "You've Lost Ritsuka Fujimaru" anime short will get the most out of this. The concept rooms in particular are aimed at dedicated fans willing to book ahead.
Good to know
Concept room reservations are made through the Karaoke no Tetsujin official website — foreign credit cards may not be accepted directly, so having a Japanese payment method or asking a local contact to assist is advisable. Standard karaoke rooms are available on a walk-in basis at most participating stores, though collaboration periods attract higher foot traffic. Collaboration merchandise sells out fast at physical locations; the Animate Online Shop window (August 6–23) is the safer option for securing items. Karaoke no Tetsujin charges by the hour per person, so budget accordingly for your group size and session length.
