Hisui Beach, often called Jade Beach, is a significant geological site located in Itoigawa, Niigata Prefecture. It is renowned for being one of the few places in the world where jade stones can be found naturally washed ashore. The beach is part of the Itoigawa Global Geopark, highlighting its importance in understanding the Earth's geological history and the formation of precious minerals.
Visitors consistently praise the unique experience of hunting for jade, describing it as a rewarding and engaging activity. Many reviewers highlight the thrill of finding even small pieces of jade, and the beautiful, clear waters. The beach is generally clean, and the surrounding natural environment is appreciated for its tranquility. Some visitors recommend bringing a small shovel or scoop and a sieve to aid in the search. The presence of local experts or guides, though not always available, is mentioned as a helpful addition for identifying genuine jade.
For a comfortable visit, it is advisable to wear sturdy, waterproof shoes or sandals, as the beach consists of pebbles and small rocks. Bringing a small bag or container for any collected stones is also recommended. A visit of 1-2 hours is usually sufficient for a casual search, but enthusiasts might spend half a day. The best time to visit is during low tide, as more of the beach is exposed, increasing the chances of finding jade. Early mornings are often less crowded. There is no entry fee, making it an accessible activity for all.
