Ōzone Oshitayashiki

In the early Edo period (1603-1867), Tokugawa Mitsutomo (1625-1700), head of the Owari Tokugawa clan and lord of the Owari Domain, established a vast residence in the Ōzone neighbourhood as a retreat from the main residence at Nagoya Castle.

The size of the original residence was about 130,000 tsubo (坪; about 429,000 square metres; 4,620,000 sq ft).

After the Meiji Restoration in 1869, the Owari Tokugawa reacquired the estate, and rebuilt the family's residence in 1900, to be suitable for their newly elevated Marquess (侯爵, kōshaku) rank.

Although the residence was destroyed during the Bombing of Nagoya in World War II, the main building of the museum survived.

The garden was heavily damaged but later restored in 2004, and the main Black Gate (Kuro-mon) remained intact.
