The Former Iwasaki Mansion and Garden was built in 1896 as the residence of Hisayoshi Iwasaki, the third president and son of Yataro Iwasaki, the founder of the Mitsubishi zaibatsu. While the original estate once spanned a vast 15,000 tsubu with 20 buildings, today about one-third of the original scale remains, featuring the Western-style mansion, the billiard room, and the Japanese-style large hall. It stands as a symbol of the fusion of Western architectural styles and traditional Japanese garden aesthetics during the modernization of Japan.
This estate is a vital historical site reflecting the reception of Western culture in Meiji-era Japan. The Western-style mansion was designed by Josiah Conder, the renowned architect of the Rokumeikan. The entire site is designated as an Important Cultural Property, preserving the lifestyle of the Japanese upper class of that era. The layout allows visitors to observe the cultural transition of Japan through the coexistence of Western and Japanese architectural forms.

The three primary attractions are the Western-style mansion, the unique billiard room, and the Japanese-style large hall.
The garden offers a different atmosphere each season. The mild weather of spring and autumn is particularly ideal for observing the architecture and the lawn. Since the last entry is at 4:30 PM, we recommend arriving with plenty of time. Please note that opening hours may be extended during special events.

Visitors can explore the interiors of the historical buildings and stroll through the gardens. A free garden guide is held daily at 11:00 AM and 2:00 PM, providing professional explanations to deepen your understanding of the architectural styles and the cultural history of the era.
Located in a central area of Tokyo, the garden is surrounded by various cultural facilities and parks. It is within walking distance of popular spots like Ueno Park and Shinobazu Pond, making it a perfect addition to a historical and nature-filled walking route.
