Mizumoto Park, built along Koaidame reservoir, is one of the largest parks in Tokyo, presenting a landscape of rivers and marshes. River improvements ordered by the eighth shogun Tokugawa Yoshimune to protect Edo (former name of Tokyo) from floods led to the construction of Koaidame reservoir which was also the source of irrigation water. That is why this place is called "Mizumoto" (literally "origin of water").
Waterways exist throughout the park. Aquatic birds such as herons and marsh ducks rest their wings there and it's a relaxing place for people like birdwatchers trying to capture them with their cameras and those just taking a walk.
In the central square with its expanse of sky and lawn, there's a stream where people can play. The area around the square has about 1,800 metasequoia trees, one of the most among Tokyo metropolitan parks. Enjoy the seasonally charming woodland landscape. Looking at the beautiful blue sky and lush green leaves reflected on the water, you forget that you are in the heart of the metropolis.
On the southside of the park is the Katsushika City Goldfish Exhibit Space where around 1,000 brightly-colored Edomae goldfish of 24 varieties are bred, providing a refreshing sight to visitors one step ahead of summer.
The Katsushika Shobu Matsuri (Iris Festival) is held every June in the Iris Garden, the largest of such gardens in the Tokyo metropolitan area. It bustles with many visitors who come to enjoy the some 200,000 irises of 100 species in colors ranging from white to purple.
Come visit this park for a relaxing time in touch with nature.
