A short walk from Yoyogi-Uehara Station, the event requires postcard applications by June 19 and visitors cannot choose the matinee or evening slot.
Koga Masao Museum in Yoyogi-Uehara will host the Koga Masao Memorial Meiji University Mandolin OB Club Concert on Saturday, July 25, 2026. The official notice says the program is split into a daytime performance with doors at 12:00 and a 12:30 start, plus an evening performance with doors at 15:30 and a 16:00 start.
The museum introduces the concert as a memorial program tied to Koga Masao's long connection with the Meiji University Mandolin Club. Guest singer Yuki Matsuzaka is also listed on the official page.
