Koga Masao Museum will hold Yashiro Aki no Sekai on September 12

Koga Masao Museum in Yoyogi-Uehara will hold Sing the Hall of Fame Honorees Vol. 28: Yashiro Aki no Sekai on Saturday, September 12, 2026. The official page lists a 14:00 start with doors opening at 13:30.

For nearby readers, the practical point is that this is a low-priced museum hall program but it still uses reserved seating. Admission is 2,000 yen, and the notice says seat tickets will be distributed from 10:00 on the morning of the event. The museum also lists writer and singer Michito Goda as lecturer, with singer Toshimi Tagawa joining as guest.

The event page says the 28th edition focuses on Yashiro Aki, who was recognized in the museum's Hall of Fame in 2025, and introduces her hit songs and career across enka, pop, jazz, and blues. The museum is at 3-6-12 Uehara, about three minutes on foot from Yoyogi-Uehara Station according to the access page, so checking the official notice before heading over is the safest plan.
