Yaezakura Swan boats lake at Kawagoe Water Park

Kawagoe Water Park – Kawagoe Suijo Kouen, or Kawagoe Aquatic Park, is one of the bigger summer pools in Saitama. Like all the other seasonal pools, it only opens for 7 weeks over the summer holidays. However, the pools are just one part of a larger recreational park which is open all year round. The park is particularly renowned for its late blooming cherry blossoms, but the somei yoshino variety are also very beautiful in this park. Kawagoe Suijo Koen also hosts a very popular flea market once a month. Moreover, throughout the year there are various festivals in the park, such as the Nippon Nabe festival in winter.

Kawagoe Water Park Summer Pools

Summer pools are a great way to get the kids to go to bed early, have a deep sleep and sleep later than normal in the morning! All that water play really tires them out and they really really love it. In 2020 the pools didn’t open at all due to the Coronavirus. However, in 2021 they initially planned to open, but once the State of Emergency was announced they cancelled those plans.

Features of the pools

One of the main attractions of Kawagoe water park is the pool with waves. It is inclined; the shallow end starts at 0 and the deep end is 1.6 metres. The waves come every 10 minutes.

Another popular feature of the water park is the large ship in the centre of the park. And the various slides are very popular too.

For small children there is a pool that is only 30cm and it has 2 small slides. My kids are in this one, somewhere!  Nappies/ Diapers are ok in this pool.

There is also a 60cm pool with a fountain that my older two kids (5 and 4) can enjoy and my 2 year old with a float.

Other features include fountains, jets, sprays and a wading river at different points in the park. There is also a simple pool. You can use a small pop up tent in the park, in fact, most Japanese people do. We may have been the only ones without, the first time we went! There is limited shaded areas in the park, so these pop up tents are very practical and for my Irish skin 100% essential!

Facilities and services

During the summer there is a special bus that runs to the park from Kawagoe and Honkawagoe stations. There are 2 restaurants, 2 kiosks and a number of vans that sell food and drink. They also have a shop that sells pool goods. There is a shower and locker room and plenty of toilets. You can play tennis, futsal and soccer. There are a number of events held over the summer including snorkelling classes. There is a no tattoo policy (see photo below). You can get a full list, in Japanese, plus more information on the official website: https://www.parks.or.jp/kawagoesuijo/

Additional park information

Outside the aquatic park there is a free public park with a small playground, a barbecue area, battery cars and a lake with swan boats for hire. It is a popular place for walking. You can ride bikes there too. In spring time the park is full of people enjoying hanami. The cherry blossoms in this park are well renowned, particularly the  late blooming yaezakura variety.

Cherry Blossoms at Kawagoe Water Park

The Somei Yoshino variety cherry blossoms pictured below, typically bloom the last week in March to the first week in April:

Where can I see late blooming cherry blossoms (yaezakura) in Saitama?

The late blooming cherry blossoms, known as yaezakura in Japanese, at Kawagoe Water Park are one of the better known yaezakura viewing spots in Saitama Prefecture. It is popular for the view of the late blooming cherry blossoms with swan boats on a lake. Yaezakura Swan boats lake at Kawagoe Water Park

The park is particularly well known for its late blooming cherry blossoms called yaezakura in Japanese. The yaezakura are on the right side of the lake if you have the rotary car park (bus stop area) at your back. They go from the battery cars to near the small playground. They typically bloom mid April and last one to two weeks depending on the weather.

In Autumn

In September the spider lilies grow. Both in the park and outside on “higanbana komichi” or Spider Lily Lane in English. The ones in the park are along a beautiful one kilometer trail:

Later in the season you can see Autumn colors around the swan lake. The following photos were taken in 2013 with an old camera phone!

Flea market

There is a flea market in the park once a month. I actually had a stall at it a couple of times back in 2006! It was a lot of fun. It always attracts a good crowd. When it is out of pool season it is generally held in the main car park for the summer pools. You can get the up-to-date schedule for the flea market on the Recycle-man website.

Update November 13th 2020: The remaining schedule for fiscal year 2020 (to March 2021)

  • November 28th
  • February 14th
  • March 7th

If you are visiting Kawagoe Aquatic park, I recommend stopping by the Saimyouji Temple next door. It was the second temple ever in all of Japan to openly promote and perform same sex marriage. Plus it has the most beautiful floral water fonts that are changed weekly!


The nearest train station is Nishikawagoe on the JR Kawagoe line. The park is a 15 minute walk from that station. Or you can get a bus from downtown Kawagoe.

  1. Looks a fun place to go. I guess if you have a tattoo you would be able to go in if you kept it covered up?

      Yes, if they can’t see it I think its fine. And actually last year my friend who has visible ones, but just in light coloured ink, had 2 of hers partially visible and nothing was said. I was reading the other day that they are thinking of changing those rules nationally, in a bid to globalise Japan a bit more! I must find and link the article. Thanks for making me think of it. ๐Ÿ™‚ And for commenting as its a reminder to go over and check out your blog. ๐Ÿ™‚

      Me too! Love waterslides that is, (mind you I’m only a couple of years off 40 too!)

  2. Wow, Japan definitely wins for most kawaii things and places huh? Seems really children/family friendly! Btw, loving your new theme! A bit lighter and spacier ๐Ÿ˜‰

      Thank you so much Summer Tan. Yes, it is so family friendly here. We never run out of things to do and all quite reasonably priced. Some really unique stuff also. It is a great destination with young children and even better to live here with small kids. ๐Ÿ™‚

  3. I’m terrified of water rides. but maybe i’ll go with my nephew to the kids pool if I visit Japan. haven’t seen a good water park in a while here, sadly

      I amn’t great on big ones I have to say. I had a bad experience once, when a big adult came down the slide after me in an aqua park in Spain and I was still under water – he landed on top of me and he didn’t realise straight away. It was probably only 30 seconds of being stuck under him – but it was so scary. If you do come here, there’s lots of choice so you might find one that suits you. ๐Ÿ™‚

  4. Looks like a fun time on a hot summer day. As a child, I spend a lot of time in swimming pools and on the beaches of California. When in Colleges, I used to be able to swim a mile. Now I walk or ride the bike.

      Thank you so much for commenting MythRider. I have to admit swimming is not my forte. I used to swim reasonably well. Then I had 3 separate incidents, spread out over years, that led me to be a little afraid of water. I like to walk and cycle too. ๐Ÿ™‚

      1. Something happened to my mother. She was terrified of getting in the water. To y good fortune, she didn’t pass her fears to me.
        Sorry you had problems. I’m glad you survived each incident.

        1. Author

          Thank you. I am glad your mother didn’t pass her fears to you. I hide my fears from my kids. I really don’t want them to feel the way I do about water, they should enjoy it. I am glad you do. ๐Ÿ™‚

          1. Author

            Thank you, but I need to be braver; I need to get over my fear. I have been trying, but… I need to try harder. ๐Ÿ™‚

          2. Author

            I like that, very true and very sage advice. Thank you.
