Nijisanji, one of Japan’s largest VTuber agencies, held the draft conference for its annual summer baseball event, Nijisanji Koshien, on July 4, 2026. The broadcast drew close to 200,000 viewers as ten teams selected their rosters ahead of a month-long training period.
Nijisanji Koshien is a yearly tournament built around Konami’s baseball simulation game Jikkyou Powerful Pro Yakyuu, using its “Eikan Nine” team-management mode. Ten Nijisanji talents serve as team managers, each building and training a fictional high school baseball squad through their own streams before competing in a live tournament.
Following the July 4 draft, the training period runs from July 5 through August 2, 2026, during which each manager will stream their squad-building progress. The main tournament will then be held over three days: August 8, 9, and 11, 2026. Matches will follow a double-elimination bracket, with games played over nine innings (extending up to 15 innings with a tiebreaker system from the 12th inning onward) at the tournament’s original venue, Crown Stadium.
The ten managers for the 2026 edition include Himawari Honma, Fren E. Rustario, Suzuna Nanase, Sara Hoshikawa, Meroko Kyouran, Rou Koyanagi, Minato Fuwa, Lauren Iroas, Ness Sakaki, and Rito Usami, each leading a team named after a fictional school tied to a Japanese prefecture. Nijisanji’s official account thanked fans for tuning in to the draft and encouraged viewers to follow the managers’ upcoming training broadcasts using the hashtag #にじ甲2026.
