Located a 15-minute walk from Tadaoka Station on the Nankai Main Line, the museum houses and exhibits Oriental art, primarily ink paintings, collected over many years by Tadaoka's wealthy patriarch, Takayuki Masaki. The collection boasts 1,300 pieces, including three National Treasures and 13 Important Cultural Properties. The approximately 300 paintings in particular, many of which are ink paintings from the Kamakura and Muromachi periods, are valuable pieces for the history of medieval Japanese painting. Both the main building and the new wing were designed by Masaki himself, creating a tranquil atmosphere perfect for appreciating ink paintings. Exhibitions are held twice a year, in spring and autumn. Each exhibition features a unique theme, combining ink paintings and calligraphy, relics of Zen culture, with complementary crafts, sculptures, and tea ceremony utensils.
