Yes and yes, double yes. As for the collection, contrary to RichardInSF's assumption, the collection is quite extensive and unusual, and the environment was "built" around the collection. The environment itself, both natural and built, is very much worth the visit and the schlep. If you can, stay in one of the Oval rooms at the very top of the hill, with a 360 view of the Inland Sea. We stayed in Room 401, which had a couple of Keith Haring original paintings. I saw the prices, and they have definitely jacked them up, when we stayed there, I think I paid 15,000 yen per night or something like that. But probably still worth it.
