under the water in pool Ogose

The summer pools / aqua park at New Sunpia Hotel and Resort in Ogose is one of the most popular in all of the prefecture. 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.

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. It 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 will release the official information around mid June on their website, but they have indicated that the summer season at the hotel will be from Saturday July 16th to Sunday August 28th. The pools generally stay open for a couple of weeks after summer season, to about mid September.

There is a wave pool at the hotel. Other pools at New Sunpia Hotel include various different sliders including tube sliders. 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.

Swimming rings are allowed. Infants are allowed in the children’s pool only and must wear a pool type nappy / diaper. Small sized pop up tents (as in the image above) 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. Sometimes the pools close 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.
