I took a little look at the venue indicated on it.
[1] [2] First, the Pilot Pen Station (2-6-21 Kyobashi) building where the Pilot Writing Equipment Museum is located.
"Meijiya Kyobashi Building" (2-2-8 Kyobashi) (19 pages of Monoshiri Encyclopedia) is opposite Chuo-dori.
[3] This is the Tokyo Square Garden building where the Environmental Information Center is located, which will be the venue for the “Environmental Activity Festival 2015” (3-1-1 Kyobashi). It's located at the intersection of Chuo-dori and Kajibashi-dori.
There is also a studio of "Chuo FM" on the ground floor.
[4] "Ginza Okuno Building" is a fairly retro building (Ginza 1-9-8). Ginza's first luxury apartment, it has become a valuable architectural heritage of Chuo-ku as a building that conveys the scent of Showa modern.
A poster for the "Marugoto Museum" was also posted next to the entrance of a manual retro elevator.
