Isanuma Park Cherry Blossom Festival

Isanuma park in Kawagoe is a frequented wooded area in a rural suburb of Kawagoe. It’s official name is Isanuma park, but recently people refer to it as Isanuma Bouken No Mori. 「冒険の森」Bouken no Mori means “adventure forest” and it refers to the wooded area in the park with an adventure playground. Although, the park is small and with few residential properties around, it has good facilities for its size and is well used. In 2023, the “jyabu jyabu ike” splash pad / water play area will be reopened for the first time in four years.

Living in Kawagoe with kids

The park is very beneficial for people living in Kawagoe with kids, but it is quite a distance from the tourist area of Kawagoe. It is not ideally suited for a stop off for a day tripper to Kawagoe. Especially if you are on foot and / or using public transport. However, if you are touring Kawagoe in a car and are coming from Omiya on route 16 you pass close enough to stop off. Similarly, if you go as far as Miyoshino Shrine or Honmaru Goten, the park is only a six minute drive away. HOWEVER, all that being said, since the sunflowers on the other side of the marsh went viral in 2020, many people now go out of their way to visit the Isanuma area every summer! This park is only about a ten minute walk from the sunflowers. It would be closer if you could cut over the marsh!!

Isanuma Park adventure playground

The adventure forest Kawagoe has a lovely playground suitable for primary school age children, but younger children can also enjoy much of the equipment. What the Japanese call “athletic playgrounds” is what we call “adventure playgrounds” in Ireland.   In 2015 the adventure playground was upgraded with some new equipment, which replaced older pieces.

Isanuma’s playground is geared for 6 to 12 year olds, but I think kids from 3 up are well able for the challenge.  And its a great challenge for adults too.  You often find adults working out on the equipment when there are few kids around.

BBQ Area in the woods of Isanuma Park

Apart from the popular adventure playground, the park also has a splash pad, a craftsman workshop, a barbecue area (temporarily unavailable on account of coronavirus) and an open space for playing. On the North end of the park, there are tennis courts, a small hotel, an event space and cafe. A bridge links the park to a wildlife reservation marsh on the East. The lake often has photographers stationed around it to capture the protected birds that live there. 

Spring at Isanuma Park

In spring the mature cherry blossoms on the avenue between the park and the marsh are stunning.  To the south of the park there is a river which also has picturesque cherry blossoms (more on the cherry blossoms here). Beyond the river there are just agricultural fields. And to the west is an industrial area which is bustling on weekends, but quiet on weekends.

Autumn in Isanuma Park

Isanuma Park is a largely wooded area, but some of the trees are evergreen. However, there are other varieties of tree whose leaves change colour in Autumn. There are a lot of oak trees in the park which not only give a lovely orange colour in autumn, they also provide an ample supply of acorns in early Autumn. It is a great spot for collecting acorns in October and early November. 

Summer in Isanuma Park

Isanuma Park

In summer, the trees of the wood and its position by a river and lake make it a little cooler than central Kawagoe. There are some Gazebos in the woods too, affording extra shade. The main attraction for families is the water play: a splash pool and wading river. The paddling pool part is only partly in the shade, but the wading river enjoys good cover from the burning sun. In 2023, the water play area is open from early April until the end of October. It is closed on Tuesday and Friday mornings for cleaning.

Another attraction during summer is the BBQ facilities. However, you need to have a local in your group to be allowed book a coveted BBQ spot. Moreover, during the pandemic the barbecue facilities are not open to the public. There is another BBQ area just across the road in the Kawagoe City Agriculture Interaction Center since spring 2023. You can see beautiful sunflowers there and in another field nearby. There are also lotus in June in the marsh for which the park is named. In mid-July, every other year Kawagoe’s fireworks display are launched from this park.

Flea Market

The park starting hosting monthly flea markets in recent years. There are several different flea markets in Kawagoe in a given month, such as the ‘Last Sunday Market’ and several flea markets at Kawagoe Park. This particular one at Isanuma Park is organized by Kawagoe Flea Market Kisha Poppo. The flea market at Isanuma has a lot of handmade goods. There are usually around 50 stalls. The markets are on from 9 am to 2 pm. The dates for 2024 are:

In the area

We often go to this park on our way to or from either the OK or Gyomu discount stores. The Gyomu store used to be on route 16, but just moved to route 254 close to Miyoshino shrine. Saitama Medical Center is only a kilometer away. Kawagoe Sports Park is also nearby.
