20th Century（トニセン） 2026年全国ライブツアー20th Century（トニセン） Osaka tickets

ORIX Theater is a 2,400-seat concert hall in the Shinmachi district of Osaka''s Nishi Ward, three minutes on foot from Yotsubashi Station on the Osaka Metro Yotsubashi Line. The building opened in 1986 as the Osaka Kosei Nenkin Kaikan (Osaka Welfare Pension Hall), then reopened in 2012 after a full renovation under ORIX Corporation''s naming-rights agreement. Its single-horseshoe auditorium with deep front rows and two steeply raked balconies is a specialist mid-size concert room — the Osaka leg of J-pop unit tours, K-pop solo fan meetings, visual-kei anniversary shows and theatrical musical runs almost always fits ORIX better than the larger-format Osaka-Jo Hall. Access is a three-minute walk from Exit 2 of Yotsubashi Station (Yotsubashi Line) or a seven-minute walk from Shinsaibashi Station on the Midosuji Line, placing it in the heart of Osaka''s shopping and dining district. Amerika-mura and Horie are both a short walk away for dinner before or after the show. The theater enforces name-check entry for overseas-artist shows; fans buying through resale channels should verify that the original purchaser''s name is still bound to the ticket before travelling.
