The Hatoyama's have been active participants in Japanese politics for many years. Most recently, Kazuo Hatoyama (1856 - 1911) was once Vice-Foreign Minister, Speaker of the House of Representatives, Tokyo University professor, and the President of Waseda University. Ichiro Hatoyama (1883 - 1959) was once Secretary of the Cabinet, Minister of Education, and a Prime Minister. Iichiro Hatoyama (1918 - 1993) was once the Vice-Minister of the Ministry of Finance, member of the House of Councilors, and Minister of Foreign Affairs. Yukio and Kunio Hatoyama are currently members of the House of Representatives.
The residence has some very beautiful stained glass windows, and a lovely rose garden. I don't think the home is impressive enough to go out of your way to see. But, it is a short distance from Chinzanso, Edogawa Park, and Gokokuji Temple. In combination, they would be a nice sightseeing choice.
