Kyu-Iwasaki-tei Gardens was built in 1896 as the main residence of Iwasaki Hisaya ,the 3rd president of Mitsubishi and the eldest son of Iwasaki Yataro, the founder of the group. At present, the site has been reduced to 1/3 of its original size, with only 3 buildings, namely the western-style residence, billiard room and Japanese residence have survived to date.

European style building , Japanese style building

The Western-style house is an important example of Japanese upper-class residential architecture during the Meiji Era.
Consisting of more than 530 square meters of building space, the two-story wooden building includes a basement. It was mainly used as a guesthouse to host important visitors. Its design is based on early 17th-century British Jacobian-style.
Iwasaki Garden contains Western-style and Japanese-style houses, both built in 1896. The Western-style residence was mainly used to host guests, while the Japanese-style house was used as a private residence where the family spent their daily lives. It is said that the Japanese house was built by Ookawa Kijur. Served as a house to hold Iwasaki family’s private events, only three rooms of the Japanese-style building remains today.

Billiard Saloon

The exact date of construction of the billiard room is unknown. However, it was built sometime after the completion of the Western-style house in 1896, by a British architect Josiah Conder. The wooden building is representative of the Gothic style, with flat log wall and carved columns. The structure resembles a Swiss mountain lodge, and Conder himself called it the “ Swiss Cottage Style” .
