Mizumoto Park is a large-scale metropolitan park located in Katsushika City, Tokyo. It is characterized as a 'waterfront park' centered around the Koai-dame reservoir, offering a beautiful landscape of water and lush greenery. The park is home to a diverse range of native and cultivated plants, providing a space where visitors can feel the rhythm of a natural ecosystem even within the urban-adjacent area. The vast grounds are equipped with various facilities including a large lawn area, an aquatic plant garden, a campsite, a BBQ area, and an adventure playground for children.
The history of this area is deeply connected to the river systems. Originally part of the old Furusato Riverbed, the current landscape is based on the 'Koai-dame' reservoir, which was managed by local residents to control water after the Furusato River was decommissioned during the Edo period under the direction of Tokugawa Iemitsu. Planning for the Mizumoto Green Space began around 1940, though development was interrupted by the war. Following the war, the area was developed according to urban planning standards, and the park officially opened on April 1, 1965. It has long been a site where nature conservation and urban development coexist harmoniously.

The park offers different charms depending on the season. It is particularly famous for its stunning views during the cherry blossom season and the iris blooming season. Key attractions include the Aquatic Plant Garden, which showcases various water-loving species, the expansive Great Lawn for relaxing, and the Adventure Playground for kids. With approximately 19,100 tall trees planted throughout the park, the environment is a dense, green sanctuary that integrates perfectly with the waterfront scenery.
The scenery changes significantly with the seasons. In spring, the cherry blossoms along the Ote-tsutsumi embankment are a sight to behold, while early summer brings the vibrant colors of the iris flowers. The park is open 24 hours a day, though certain facilities are best enjoyed during daylight hours. By checking the blooming status of seasonal plants, you can plan a visit that aligns perfectly with nature's cycle.

Mizumoto Park offers a variety of ways to engage with nature. The campsite and BBQ areas allow for outdoor dining and overnight stays, making it a popular spot for social gatherings. For families, the Adventure Playground provides a great space for physical play. The park also features an outdoor stage for events and community gatherings. Whether you are looking for an active adventure or a quiet stroll through nature, there is something for everyone.
The park's territory spans across both Mizumoto in Katsushika, Tokyo, and Misato City in Saitama Prefecture. The area shares a unified waterfront landscape with Misato Park in Saitama, located across the Koai-dame reservoir. The western side of the park is bordered by the Sakura-tsutsumi embankment, creating a continuous natural corridor.

Because the park is so vast, please prepare according to the weather and season. Comfortable walking shoes are highly recommended. If you plan to use the camping or BBQ facilities, please follow the specific rules provided by the facility.
