Message from CEO

I have been working as a CEO for over 30 years at a well-established Go Board & Go Stones Company with more than 100 years of history.
Based on various hands-on experiences, from sourcing Kaya logs to producing Kaya Go Boards, I have infused my enthusiasm and effort into the industry.  To produce Go Stones, I developed an innovative technique - the Diamond Drill Clamshell Cutter, and also started up a raw material processing plant in Mexico. 
On the basis of years of experience and knowledge, I am confident that I can provide the most accurate appraisal and repairing service of Go boards and Go Stones for our customers.


Born and raised in Hyuga City of Miyazaki prefecture, one of the country's leading areas for Kaya Go board production and the origin of clamshell Go stones, and with over 50 years of experience in the field, specialized in making and repairing Go boards and stones, appraisal and trading.
