To accommodate fans attending the professional baseball Climax Series First Stage at Belluna Dome, Seibu Railway announced it will operate temporary express services known as the Stadium Express, according to the railway’s official service schedule. Advance tickets for the reserved-seat trains go on sale October 7, 2026, at 7:00 a.m. local time.
Stadium Express Trains Run from October 10 to 12
The temporary Stadium Express trains are scheduled to run from October 10 through October 12, 2026, serving Seibu-kyūjō-mae Station, the closest stop to Belluna Dome. All Seibu specialty express cars are fully reserved seating, requiring both a standard ticket and an express ticket for boarding. Passengers who board without purchasing an advance express ticket face an additional 200-yen fee per express ticket on top of the regular fare for the utilized section.
Refund Procedures for Game Three Cancellations
Operations depend directly on the postseason series results. If either team wins the first two games of the Climax Series Final Stage decider, a third game scheduled for October 12 will not be held, and the corresponding Stadium Express trains will be canceled. For passengers who purchased advance physical tickets at station counters or JTB locations, refunds will be issued without service fees when tickets are presented at Seibu Line stations or the original purchase location. Tickets bought through the Smooz digital ticketing service will be automatically refunded to the original credit card or PayPay account, requiring no manual action from the buyer.
Express Vouchers Go on Sale October 7
Sales for the express vouchers begin simultaneously on October 7, 2026, at 7:00 a.m. through multiple channels. Riders can secure passes via the Smooz mobile ticketless service, at designated Seibu Line express ticket counters, or at participating JTB store locations once individual branch offices open for business. Seibu Railway recommends using the Smooz smartphone application to purchase passes digitally ahead of travel.
