The summer pools / aqua park at New Sunpia Hotel and Resort in Ogose is one of the most popular in all of the prefecture. In fact, Walkerplus, gave them a coveted “Walker Award” in 2022, naming them as thee most popular summer pools in all of Japan. Despite being much smaller and more expensive than the municipal aqua parks, such as Kawagoe. Maybe one of the reasons the pool was so popular during the pandemic is because you don’t need to buy a ticket in advance, you can buy one at the door. Which – since the pandemic – has become the exception to the norm.

New Sunpia Hotel and Resort

New Sunpia Hotel and Resort despite its name is not “new”, in fact it is quite old and many of the facilities reflect this. However, the pools did undergo a renovation in recent years. Although, you wouldn’t think it to look at them now! New Sunpia is located in Ogose City in Western Saitama. In the renovations they did a few years back they added a wild campsite in the forest behind the hotel.

In 2024, they are planning to open July 13th to 15th and then again daily from July 20th to September 1st. However, if rainy season ends early they may suddenly decide to open earlier. As happened in 2022 – they initially planned to open July 16th, but suddenly opened on July 2nd! The rainy season was late to start in 2023. I wonder what way it will go this year!

From the original post I wrote back in 2017. I just love this photo, by the hotel, of the pool being blessed by a shinto priest before it opened for the 2017 season.

Old post, but it shows the pool being blessed before the season opens

The wave pool is the main attraction of the aqua park at Sunpia Hotel. Other than that there are small pools which serve the sliders. There is one large tube slider and two medium sized slides. There are also slides for smaller children in the children’s pools. In addition, there are two different children pools – one is only 21 centimeters high for infants. The other the water is 62 centimeters high. Again, both are very small.

Swimming rings are allowed, but not beach floats or anything larger than a swimming ring. Infants are allowed in the children’s pool only and must wear a pool type nappy / diaper. Small sized pop up tents are allowed, but tarps, sun umbrellas and large sized tents not allowed. Unfortunately, they don’t allow people with tattoos, even if they are covered, to use the facilities. Also, please note, sometimes the pools close suddenly due to weather. Not necessarily if its raining – we’ve been there in the rain before – but presumably they judge by the amount of rain and/or temperatures. They post on their website every morning, during the season, to say whether or not the pools will be open that day.


This pool gets in excess of 1000 visitors a day. Honestly, this really surprises me, because the pools really don’t feel large enough to accommodate that amount of people! But it is not uncommon for people to line up from early morning to be one of the first to get into the aqua park.

Walker pool awards 2022

For some reason Walker didn’t do their usual All Japan Pool ranking in 2023. The last time they did it was 2022 and Saitama Prefecture did really well that year! Not only was Sunpia crowned as number one, three other of Saitama’s pools / aqua parks made the top ten list. And a further two were in the top 20:

#1. Hotel New Sunpia
#3. Seibuen Pools
#5. Kawagoe Aqua Park
#10. Tobu Super Pool
#13. Shirakobato
#14. Aqua Patio Paradise
