The sign on the window states that: 1. You must wear a mask 2. Customers are to use hand sanitizer when entering 3. The max number of patrons is three people I have no idea what this shop sells and it was closed when I passed it by at the station.
I had a chance to visit Kamata station while here in Tokyo. It’s a pretty busy place surrounded by lots of good shopping. I would like to come back on my day off to really look around.
