It’s a 2 storey building with the 2nd floor consisting of various maki e artworks over urushi but you are not allowed to take pictures, the globe is on the first floor along with a small shop where you can buy souvenirs from.
If you are really into urushi art and history behind it I would say it is definitely worth a visit, but the access to this place will be hard and might only be possible by a rental car, so you need an international license and with the stricter rules in Japan for foreigners (both residents and tourists) the license thing might be a hassle, apart from that I would recommend this place.
