Overview

The Tenryu River Mouth is a kitesurfing spot located in Shizuoka Prefecture, where the Tenryu River flows into the Pacific Ocean. This spot offers a varied body of water, between the river mouth and the open ocean. The dominant wind in summer comes from the southwest with regular thermal breezes, while winter brings stronger northeast winds. The river mouth creates current zones that need to be known. The bottom is sandy with sandbanks that shift with the seasons and floods. The spot is suitable for intermediate and advanced riders due to the currents and Pacific swell. Parking is accessible nearby. Be aware of fishing areas and boats that also use the river mouth.
