This is a full set of the coveted Suwabute Go Stones, often called Hyuga Clamshell (Hyuga Hamaguri) or Hyuga Go Stones. Japanese Suwabute clams make the finest Go stones available and sit at the pinnacle of the Go industry, along with the legendary Hyuga Kaya boards and Shima-Kuwa bowls.
About Suwabute Clamshell Stones

Suwabute clams are harvested off the coasts of Hyuga City in Miyazaki Prefecture, Japan. These clams require a minimum of 20 years before they are large enough for stones, and with an average life expectancy of 15 years, they have all but disappeared from Japan's terribly over-fished waters. While not endangered, Suwabute clams large enough for stones are almost impossible to find.

These stones are prized for their exceptionally fine grain. The grain from all grades of Suwabute clam puts to shame even the prized Snow (yuki) grade Mexican go stones. Their fine grain not only looks exceptional, but adds to the durability and strength of the stone, making them far less prone to chipping or damage than their Mexican and Hainan counterparts. This fine grain is the result of, in part, species of clam and the Pacific's beneficial Kuroshio current. In addition, Suwabute clam stones maintain their original luster as they age, while Mexican stones tend to yellow over decades.

Harvesting of these beautiful shells began in mid-late Meiji era Japan (sometime roughly between 1890 - 1905) when artisans discovered that the clams were not only large, but made superior stones. Because of the growing scarcity, Mexican clamshell became the norm after the 1920's, though Suwabute were still regularly used. Suwabute stones are graded differently than their Mexican counterparts. Mexican clamshell is graded on the grain. The more lines in the shell, the higher the grade. Snow (Yuki) is the best, followed by Moon (Tsuki) and then Standard/Practical (Jitsuyo)

Unlike Mexican shells, Suwabute have fine grain throughout. The clam is quite colorful so the stones are graded on their whiteness rather than amount of grain. Today, the shell stones are exceptionally rare and sold at an according premium.
