all the branch websites are listed here:
http://www.gtiroz.net/links.html
although they rarely get updated these days
they are all still at some level of activeness...
(that pic is actually from may - when they have their annual national meet every year)
afaik there are no active english-speaking (or typing) owners and have not been for many years
i have been in contact with the president of the "south kanto" (tokyo) branch for several years now,
we communicate (slowly and innacurately) through translation software (although have not spoken to him for over 6 months now)
i have been meaning to chase him up for info regarding the red one 8)
cheers,
