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, has given 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, it is not uncommon for people to line up from early morning to be one of the first to get into the aqua park.

Last update: July 2nd 2022.

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.

New Sunpia Hotel Pools

Sunpia initially indicated that the summer season at the hotel would be from Saturday July 16th to Sunday August 28th. However, due to the hotter than normal weather and the early end to rainy season, they opened their pools today, Saturday July 2nd. However, the pools will only open on weekends until July 16th. From July 16th they will open daily until Monday August 29th.

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

The wave pool is the main attraction of the aqua park. 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. 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. They post on their website every morning, during the season, to say whether or not the pools will be open that day.


In 2021, due to the pandemic they limited the number of visitors to 1200 people per day. Honestly, this really surprises me, because the pools really don’t feel large enough to accommodate that amount of people! In addition, hours were shorter than normal in 2021. The hours are shorter in 2022 too, but they currently haven’t mentioned limiting the numbers.

Address: 700 Furuike, Ogose, Iruma District, Saitama 350-0401
