Look how big the Kato line is........Also check out the Green Max line......I bought a number of Green Max structure kits just because they were so COOL and cheap! Per capita I know Japan has many more model railroaders than the USA. N scale rules, Z is more popular than in the USA and they have T scale 1/450!!!
Just look at Kato track offerings.....things like a double cross over with full remote control for around $40!! Good looking stuff......tempts me often....then I recall all that track cleaning and trying to work on a N scale loco!!!
