Question about a door. 1-10-12 Nipponbashi, Chuo-ku, Chukuru, 1-10-12 Nipponbashi

Hi one of my friend's acquaintances is in Japan and he saw this door. I haven't seen this before.

Any idea what this is about?

Didn't know Takoyaki shops had entrances like that?

That would be the doorway for a hotel health. They're not permitted to have specific signage.
