Kazusa Sarashina Park Jabujabu Pond

About this spot

This is Kazusa Sarashina Park Jabujabu Pond, a free water-play area in Kazusa Sarashina Park in Ichihara City. In 2026 it is open from Wednesday, July 1 to Monday, August 31, from 9:00 to 17:00. It is closed all day on Thursday, July 30 for cleaning and a water change, and it is also called off on rainy days, on days when the temperature is 25°C or below, and in stormy weather with thunder or strong wind. Footwear made for water play is required, and putting your face in the water, diving, and drinking the water are not allowed, so go over the rules with your children first. It is an open park ringed by wide lawns, and with a shopping mall next door you can quickly buy anything you forgot, which is reassuring. Since it is free, you can also use it for just a short stop.

Tips

Footwear made for water play is required, so prepare on the assumption that bare feet and sandals are not allowed. It is closed on Thursday, July 30, so plan around that date. It is called off when the temperature is 25°C or below, so check before leaving on mornings that stay cool. It closes at 17:00, so starting to get changed around 16:00 makes for a calm trip home.
