Oiso is part of Shonan, a popular destination for beach, located along the beach side of Kanagawa Prefecture. It is a historical town in terms of Japanese beach culture. It is indeed the first beach town where Japanese people went swimming in swimsuits back in the days. Located by the ocean, you can hear the waves crashing and can smell the sea breeze while having fun at 9 unique swimming pools such as the wave pool, diving pool, synchronized swimming pool, flowing pool, and the water slider. The wave pool is just like the real ocean, where you experience the waves coming and going.

Few other things to keep in mind!

Since this is a water park for everyone, there are a few other rules you like to be aware of. For those who want to smoke, there are few smoking rooms located around the water park where it is separated from the rest. Oiso Long Beach attracts a lot of children, thus smoking areas are clearly differentiate. You are also not allowed to bring in body boards, fins and snorkeling gears at the water park. Each pool has different guidelines for what floating devices you can bring in, so for safety reasons, you might like to ask the nearest lifeguards to make sure what you have is appropriate. Lastly, like many other facilities in Japan, Oiso Long Beach does not allow people with tattoos. Thus, unfortunately, if you have a tattoo and even a temporary one, you will not be allowed to enter the water park.

If you are staying in Tokyo, it takes roughly 2 hours by car or with public transportation to Oiso Long Beach. You can certainly do a day trip there, as the park opens at 9:00 a.m. and closes at 5:00 p.m. However, if you are interested in spending some extra time in the Shonan area, you can stay at Oiso Prince Hotel, which is a part of Oiso Long Beach resort. By doing so, the entrance fee for the water park, which is normally 3,700 JPY (30 USD) for adults, becomes half of the price. Similarly, 2,500 JPY (20 USD) for Jr. High and High school students, 1,500 JPY (12 USD) for primary school students and senior over 65, and 1,000 JPY (8 USD) for children over 3 years old, become half of the price. If staying at the hotel is not an option, you might be able to find a discount ticket at convenience stores.

A beach day out!

If you are traveling to Japan, you definitely have to see the culture outside of major cities like Tokyo, Osaka, and Kyoto to learn what Japan is really all about. If you are a little tired of busy city life and want to escape the hot and humid Japanese summer, why don’t you hop on a train to visit this relaxing, yet exciting beach resort in Oiso Long Beach? The water park is only open during summer from beginning of July to mid-September (this year from July 4th to September 13th) so it’s only for a limited time, but if you visit Oiso Prince Hotel during other seasons, you can still enjoy tennis and golf all-round the year.
