The garden of the Nakano family, a wealthy merchant, is open to the public.

Hanroku refers to Hanroku Nakano, a member of a famous family that prospered in the shipping and brewing industries during the Edo Period. The garden of the Nakano family, which Hanroku loved so much, is open to the public and serves as a place of hospitality for tourists. The black walls of the four storehouses have been beautifully repainted, and toilets and a pavilion have also been installed, making the spot perfect for strolling and resting. Incidentally, it is said that because this circuit-style Japanese garden was close to the sea, seawater was drawn in, and the water level of the fountain rose and fell according to the ebb and flow of the tide.
