It is a common stone basin in traditional Japanese gardens, used for visitors to wash their hands and rinse their mouth before entering shrines or temples to purify their body and mind. It is usually carved from natural stone and has various shapes, but the most common ones are round or square. Its design is simple and elegant, blending harmoniously with the surrounding environment. In Japanese culture, a water bowl is not only a practical facility, but also a spiritual symbol that reflects the Japanese people's respect for cleanliness, purity, and humility. When using a hand water bowl, visitors will follow certain etiquette: first use a spoon to scoop water to clean their left hand, then clean their right hand, then use their right hand to scoop water to rinse their mouth, and finally clean their left hand again and put the spoon back in place
