Yesterday I went to Kaiyodo's 40th anniversaly exposition ( http://www.kaiyodo40th.jp/) at Shinjuku Takashimaya.
Kaiyodo started as a plastic model shop. But the originator O. Miyawaki was so enthusiastic and eccentric a person that the history of Kaiyodo is extremely anecdotal. Now Kaiyodo has become the world's best miniature manufacturer. I hope that someday the books about Kaiyodo are translated into English.
