A really small TT from Honda (Japan only)

That one is a concept. What is actually available can be seen on the website for the camper show. Navigation is not too difficult even if you don't read Japanese.

Casita in Texas exports 13-foot and 16-foot TT models to Japan, with some equipment changes for their different utility and safety standards.

cute... only if you're 5'2"

There's another thread with this, and it's a concept vehicle, not expected to ever be production.
