Two years ago and then again last year, I was in Japan and had the opportunity to visit Tamiya’s main office in Shizuoka along with their R/C car track. The latter looks a lot bigger on TV. Anyways, I’m not going to add a lot of text right now, but putting this online since it is worth the visit and little seems available on the web. BTW the last time I went, apparently one needs an appointment contrary to the info on Tamiya’s web site. The showroom is a must go especially if you do the model show.
