Verified October 2026
WAVEPARK BIWAKO is a planned tourism complex built around a wave pool on the Karasuma Peninsula in Kusatsu, Shiga Prefecture, on the shore of Lake Biwa. The developer, JPF Co., Ltd., a Tokyo company founded in 1957 that manages public racing venues, was approved in March 2024 as preferred negotiator for about 9 hectares on the peninsula that Kusatsu's land development corporation bought from the Japan Water Agency in 2019. JPF's proposal is a beach-culture hub centred on an artificial surfing facility, and it says the park will open in 2029.
JPF's wave pool business rests on a 2021 agreement with Wavegarden to develop up to seven Wavegarden Coves in Japan over seven years, and its wave pool site describes Cove waves from 50 centimetres to 2 metres, up to 1,000 an hour, with rides of up to 16 seconds. The Biwako announcements do not yet give the lagoon's size, module count or wave menu.
No pricing announced.
Nothing to book. The Karasuma Peninsula is about 40 minutes by car from Kyoto Station, about 1 hour 15 minutes from Osaka Itami Airport and about 2 hours 10 minutes from Kansai International Airport.
