Dentist again

I had my teeth cleaned today...
In Japan the dentist stains your teeth a light yellow so they will look natural.
My thinking is that natural is the color after they are cleaned...white. ヽ(？_？)ノ

I guess I think too much.

Cont: walk

A Hakkeijima station. I wonder if the sameperson put down these arrows?

walk on the left

I have been told that you walk/stand on the left in Japan. . Someone forgot to tell the guys who put down these arrows. (^^)v
