Scenery series 1/80, 1/87 scale suit for HO gauge, so have fun running through Japan! Have fun with running though Japanese life architecture.
Here below are 1/87 scale that you can buy direct from Japan on amazon.co.jp and Rakuten Global. But as you may know instructions are described in Japanese! So ask your Japanese friend to help, or try with the illustrate (which is well pictured) and youtube.
