Just outside Wakamatsu-Kawada Station on the Oedo subway line in Shinjuku Ward, Tokyo, stands an elegant building with cream-colored exterior walls and an entrance with a modern canopy decorated with a motif of grapes.

Completed in 1927, the two-story residence was home to Count Nagayoshi Ogasawara, the 30th in the family line that during the Edo Period (1603-1867) reigned over the Kokura Domain, which today is Kitakyushu, Fukuoka Prefecture.

With a tiled roof, arched windows and a courtyard, the architecture is a prime example of Spanish colonial revival, a popular style for Western-type buildings in Japan in the early 1920s to the 1930s.
