This museum is tough to recommend for its normally displayed collection, which is tiny (by tiny, I mean 30 pieces max). It's also not easy to get to, being a 15-20 minute walk from the nearest train station and buses aren't much better. As such, if you're going to visit I recommend seeing what the special collection is that they have on display - their special collections take up their main display room, which is 3x the size of the rest of the museum. If the special collection is not to your taste, I would not recommend visiting.
If it is however (or if you have access to a car and can make the journey without depending on the limited public transit options, it is a charming building with a very good gift shop - there are a number of prints done via woodblock techniques if you're looking for one (plus a lot of other ukiyo-e-related gifts that I haven't seen anywhere else in Japan). In the end I'll give it four stars for the quality of their special collection curation, the format shop, and decent AC on a hot day... just be warned it might not tick all of your ukiyo-e boxes.
