I’d never heard of this place until recently – via the timeout Japan website. I always have a lttle look to check out what I might have missed. This was a really lovely museum with square proportioned rooms, a feeling of balance and the whole building felt ‘normal’. Despite it being made of concrete, it has various architectural additions to the outside that give the illusion that it is an old building. Very clever. Inside (no photos allowed hence only one) the ground floor was made up of rough diamond-shaped stone. Beautiful and clean.
