Kazo Hanasaki Park in Autumn

Kazo Hanasaki Water Park made quite an impression on me. It isn’t a huge park, but there is a lot to do in the relatively small area. So much so, I recommend it as one of those parks that it is worth a journey to with kids, even just once. That is, if you are in that area of Saitama! This post contains information for both the spring and autumn festivals.

There are two main attractions of this park. One is the water park, which is available from mid July to end of August. It has a number of different pools, including one for kids, and a Jacuzzi . You can also rent floats, pool beds and a boat for a separate charge. The pools are turned into fishing ponds in the Winter!


The other main attraction is the bike hire which includes some pretty unusual and fun bikes. The bikes are charged by the hour for the number of people that can ride them. They have quirky bikes for one, tandems for two (of course!), even a car bike, for want of a better description. Its a bike in the shape of a car, or maybe a car that you cycle! Oh…maybe we call them pedal cars – please comment if you know the answer! Whatever you call it; its great fun. The kids loved this the most.


Kazo Hanasaki park has a lot to offer other than the most popular attractions. The playground has a great big combination piece of equipment. Beside it there are some spring rides and small slides suited to small children. They also have stepping stones, climbing rungs, a little house and other pieces of equipment. There is a large gazebo beside the play area with benches and a couple of tables. Nearby is a wading river that opens early June. The BBQ area can be used during that time too.

There is also a scenic river on the far side of the park lined with magnificent conifer (meta sequoia) trees. Beside it there is a walkway with a wooden path over a type of lotus pond, with other beautiful scenery in different seasons.  

Spring in Kazo Hanasaki Park

There are approximately 200 somei yoshino sakura in the park. However, Hanasaki has several different types of cherry blossoms, including late blooming yaezakura, so you can usually see cherry blossoms even in mid April. Early on in spring they have a popular Spring Festival:

Kazo Hanasaki Park Spring Festival 2024

The 2024 spring festival is on Saturday March 10th and Sunday March 11th from 10 am to 4 pm. On both dates they have booths and food trucks. They also have a craft market and live entertainment both days. Moreover, there is a festival booth area for kids. There are also games for children. In addition, on the Saturday they can ride a coal operated mini steam locomotive for 300 yen. On the 10th they will have a bouldering corner. Official event page.

In Autumn you can see Autumn leaves in the pool area of the park. There are some kochia and cosmos flowers too. There is an avenue of gingko trees from the car park to the pool entrance of the park. The barbecue area is ideal for an Autumn BBQ too. Please note that due to the pandemic you need to book the BBQ area in advance.

Other things to do in Kazo Hanasaki Park

There is a lake with pedal, swan and row boats for hire. The battery cars in the pool area are accessible most of the year. They have putter golf and sports grounds. There is a small flower garden maze and a wide open grass area. The BBQ area is particularly popular. It is very nicely done. And there is even a restaurant on the grounds.

The pools are used as fishing ponds out of season (don’t want to think about that too much!).  And they have fishing competitions in January. In 2024, they will be on January 13th, 20th and February 10th. Moreover, they have a regular flea market at least once a month (weather permitting). Upcoming dates in 2024:

  • Monday May 6th
  • Sunday May 12th
  • Sunday May 19th
  • Sunday May 26th
  • Sunday June 2nd
  • Sunday June 9th
  • Sunday June 16th
  • Sunday June 23rd
  • Sunday June 30th

So you see, it is a park worth families with small kids visiting at some point, even out of summer season. If you do plan to go during the summer, please see the up-to-date charges on the website, linked below. The park also recommends that you arrive early to get a parking spot, particularly on Saturdays when the park is at its busiest.

  1. Awesome!
    My kids are probably a bit old for this, but I can take my nieces here. Great.

      That’s the thing its probably best suited to younger children. My oldest is only 11, but he enjoyed the bikes and the swan ride and after that just kicked his rugby ball around the green area for the rest of the day 🙂
