Japan Ukiyo-e (Ukiyoe) Museum is a print maker’s dream, holding the largest private collection of ukiyo-e (woodblock prints), paintings screens and old books in the world. The Sakai family has collected more than 100,000 pieces over several generations. English information is limited, but there is a pamphlet you can get at the front and the staff are very friendly.
It’s a little tricky to find. Check out the map.
The Museum is located beside the Court and Historical Village (Rekishinosato). So see them both at once.
