Takai Kozan was one of the wealthiest farmer-merchants of Obuse. Highly cultured and intelligent, he studied Confucianism, Sinology and Western sciences. His house was frequented by all sorts of intellectuals like Katsushika Hokusai, Sakuma Shozan, and many more. When visiting the Memorial Museum, you get to see the interior of an Edo Period-style house, decorated with works of art made by the owner. If you’re a fan of art or history, you might like to see this place. A visit to the museum is best-enjoyed along with visits to the nearby Hokusai-kan Museum and Ganshoin Temple.
