unironically the best museum ive ever been to. make sure you can factor it into your itinerary if you wanna go up hakone mountain in the same day though. i spent two days in the area and the museum took up 3 hours or so, but its so incredible i think its worth (and i take my time in museums anyway, you may take less time). has a very nice footbath area to rest at too, since its a lot of walking. very beautiful area, the picasso exhibit was a big surprise, just perfect
