About the material of Kamakura
Kamana Arrow is mainly used in Katsura wood. Cataru's trees are suitable for wood grain and delicate sculptures, and are preferred as a base of Kamakura.
In the case of a circle (about 30 cm) tray, we will make a double thickness of 60 cm diameter 60 cm and make a log of Katsura. When this size is a log, the age is around 300 years.
If you think that there is a history of 300 years in a single tray, it is a great impression.
