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