SegaNET Mahjong MJ is in its 13th year of service, with a live tournament stream scheduled for July 16, 2026, and a recently concluded collaboration event with a Lupin III pachislot machine.
SegaNET Mahjong MJ continues to operate as a live-service arcade and mobile mahjong game, with two recent events showing its ongoing community engagement. The game will host a 13th Anniversary Tournament live stream on July 16, 2026, featuring four M-League players: Genta Takeuchi, Yu Suzuki, Akina Mizuhara, and Takanori Nagai. Commentary comes from Maki Asami and Koshin Asakura. A support campaign offering autographed tumblers runs until the stream begins.
In June 2026, the game ran a collaboration event with the Lupin III pachislot machine L Shuyaku wa Zenigata 5. The event, which lasted from June 1 to June 21, included a nationwide tournament and a gacha with themed items available for both the app and arcade versions of MJ. The two events show the game still draws professional players and ties into other Sega properties for cross-promotion.
