Tourist Spots

Akigase Park
Akigase Barrage is located on the right bank of Ara River, but Akigase Park is located on the left bank on the riverbed. It was organized as a kind of urban city park and opened to the public in 1971. It covers 100ha of space, consisting of ball game stadiums, tennis courts and many playgrounds for children. To make use of the original green (tree/bush) areas, this park provides local and nearby residents with leisure site. On the southern edge, this park is also connected with SAKURASO Park, i.e. Primrose park. The central part of this park is the natural conservation ground of a large space of natural primrose colony. In spring, a lot of primrose seekers visit this park and stroll through Akigase Park as well.

Saiko Reservoir and Doman Green Park
On the southern side of the above Sakuraso (Primrose) Park, Doman Green Park is connected over Kamo River. This park has 38 ha of park zone surrounding the flood control regulating reservoir named "Saiko". Cycling and service road along the edge of the reservoir is suited for bike ride and a lot of bike riders are seen on weekends as this is close to the starting point of bike trail on the bank of Ara River toward Forest Park in Namegawa Town. Unfortunately accessibility to this park and Akigase Park is not good as they are rather far away from the railway route. The bus service is available from Musashiurawa and Urawa stations.
