Yostar Inc. will be holding a real-life event, “Jantama 7th Anniversary ~Konten-Jinja Reitaisai~,” to commemorate the 7th anniversary of its competitive mahjong game, “Jantama,” on Saturday, May 2, 2026, at Tokyo Big Sight South Hall 1. Admission is free.
Inside the venue, there will be an event called “V no Ma” where you can play against VTubers directly. The participating VTubers are Kurono Chiba, Moko Sakino, Niina Asahi, Rotan Ryusei, Rinon Amagome, Meika Utano, Izumi Yuzuhara, Kozeni Nekonade, Chieri Hanakyoin, and Marugericha—10 in total. You can sit at the same table as your favorite VTuber and enjoy playing against them while chatting.
Numbered tickets will be distributed from 10:40 AM on the day of the event in front of the reception area for the “V Room” matches. You cannot choose your VTuber or the match time. Due to scheduling constraints, matches will end after 15 minutes. Distribution of numbered tickets will end once they run out.
Kurono Chiba commented, “Mahjong The Reitaisai Soul is here again this year! Let’s have lots of fun together to celebrate the 7th anniversary! We look forward to seeing you there!” Koze Nekonade commented, “Happy 7th anniversary! I love celebrations and Soul Mahjong, so I’m so happy to be involved! I’ll win with Musou Kokushi.”
Please note that you will need to bring a device capable of playing Mahjong Soul online to participate in the match.
