Interesting, I have not seen any of the Thomas-series trains produced in Japan in 1995 so far but it could be possible. It is definitely a Japan-made shell, the Japanese production stickers are wider and stamped with the production code and the Thailand ones are smaller, squarer printed ones. The Japanese ones are more commonly on the side of the shell and the Thailand ones more commonly on the bottom of the cab roof
I have a website where I have been writing about and photographing many of the sets and pieces that I find interesting.
