Kansen-en Park
This small park was previously the residence of the Shimizu family, one of Tokugawa Gosankyō, and one of the most prominent families of the Edo era. After the Meiji Restoration in 1867, it was transferred to Marquis Souma. The name "Kansen-en" (literally "sweet spring garden") derives from the fact that the spring water in the garden was sweet and suitable for tea. Since Kansen-en was built during the Edo period, its style is typically Edo. There is a gourd-shaped pond, called "Yamabuki-no-ido" (meaning "well of the Japanese roses"), in the middle of  the garden, which is surrounded by flowering shrubs. At the south end of the park is Mishima-Yama mountain. Mizu-Inari Shrine is also located on the site. The park is located approximately 10 minutes' walk from Waseda Station, and it is open　from 07:00 until 19:00 (until 17:00 from November to February).
