Iris and hydrangea Ageo Maruyama Park 2021 Saitama

Ageo Maruyama park is frequently listed in Saitama’s top 3 list of family parks. It is personally one of my favorites.  I love that although the park is big, it isn’t massive. Furthermore, there is so much to do and see that you can spend a full day there. Moreover, it is very picturesque throughout the year. It is an ideal park for cherry blossom viewing, particularly with children. In addition, the autumn leaves and, in summer, the iris attract media attention and draw photographers and sightseers from not only Saitama, but further afield too. Best of all; the facilities and attractions in the park, even the zoo corner, are completely free. 

The most recent TV appearance for the park was on June 7th 2021 on NHK, Japan’s solo public broadcaster. They reported on the iris live from the park. It prompted me to completely revitalize the original 2012 post on this blog and republish it as “new”. Apologies that some of the photos are from the original 2012 post and the quality isn’t great. I rarely brought my camera with me back in the day, with four kids under five at the time. Moreover, the few photos that I did get to take were hurried jobs with an old flip phone, remember those!? I digress! Since the NHK live broadcast the iris have peaked, but there are still some holding on. Moreover, the hydrangea have come into full bloom. If you are looking for somewhere to see iris and hydrangea together, Ageo Maruyama Park is a very good option.

Ageo Maruyama Park

Ageo Cherry Blossom Festival
Main playground with roller slide and stunning sakura

Ageo Maruyama Park is a sprawling 15 hectares park in suburban Ageo City. Among the several features of the park are three playgrounds. One is quite small with just a cement slide, climbing wall and sandpit, but the other two are large and includes an athletic playground. What I particularly like about this park is that the seasonal scenery is integrated nicely with the play areas. The kids get to play while I get to enjoy the cherry blossoms, hydrangea, autumn leaves etc. When my kids were younger I appreciated the swings that with back and stomach support for toddlers, which is a rarity in this area of Saitama.  Another benefit for families with young children is that the (free) parking is off road and right beside the toddler friendly playground.


  • Lake, pond and other water features including a wading river with shade. It is shallow and suitable for toddlers to play in.
  • A small “zoo” with monkeys, goats, rabbits, Meerkat and guinea pigs. You can hold the latter (guinea pigs) during the free petting hour. The petting hour has been temporarily suspended during the pandemic.

Maruyama Park through the seasons

It is very pretty in the Spring, first with plum blossoms then with cherry blossoms. There is an early blooming cherry blossom area since around 2014. The park has several different varieties of sakura. It is a popular place to do “Hanami” (Flower viewing picnic). 

In summer the wading streams, fireflies and beetles draw families from afar. You can see the fireflies in July. There is normally a viewing event, but it may not be able to go ahead in 2021. Furthermore, the iris and hydrangea have become quite famous and attract photographers, Instagrammers and cosplayers. They normally have an iris festival from the end of May to around mid June, but due to the pandemic it was cancelled in both 2020 and 2021.

In Autumn the photographers come back again to capture the leaves vibrant colors.  You can collect acorns in early winter. On a rainy day you can enjoy free access to the nature education hall.

      GAHH! This went into spam too. I am going to ask Bluehost about it, because I can’t figure it out myself. Must be something dodgy about your name Andy. 🙂
