Hmmm... finding Westfalia´s in Japan is difficult. Wrong hemisphere. Volkswagen is not selling them in Japan as Toyota has similar (less luxury) buses for 1/3 of the price.
My neighbour was marketing lead for Volkswagen Japan and they only sold a few of them in 2008 as special service like e.G. to the german embassy.
Sometimes I saw a very old one and there are some "fake" busses driving here. They look like a T2 with one windshield window but they are not as wide as regular cars and have a huge VW logo in front. No idea who produces them but they are definately no Volkswagen ones.
Let´s see where i bring you next. Btw.. I upload a picture from the most exciting spot within the zoo near by for our children.
