Ketsumeishi to hold outdoor stadium concerts at Ajinomoto Stadium in 2027

The Japanese rap group Ketsumeishi has announced a two-day outdoor stadium concert at Ajinomoto Stadium in Tokyo, scheduled for April 17 and 18, 2027. Titled ‘Ketsumeishi 25th Anniversary “Nigo no Yoru” ~Tonight, the Twin Brother Sings~’, the event marks the group’s first outdoor stadium performance in approximately 11 years.

The announcement was made during the final performance of their 25th-anniversary arena tour, ‘Ketsumeishi 25th Anniversary TOUR Ketsumen CAMP 2026’, held at the Ginowan Seaside Park Outdoor Theater in Okinawa. The group expects to draw a total of 100,000 attendees over the two days. Group leader Okura described the upcoming stadium event as a massive ‘after-party’ and a ‘large-scale karaoke competition’ where they would perform songs requested by fans.

The Okinawa finale featured a 23-song setlist including hits such as ‘Natsu no Omoide’ and ‘Ofutari Summer’, celebrating the group’s major debut anniversary.
