Cradle of the Komatsu Brand

A 1-mm hole is made in a cylindrical stone bead of 2 mm in diameter by using a stone needle of 0.7 mm thickness.
This is such an amazing processing technique that is hard to restore even nowadays.
These cylindrical beads were made by the Yayoi people 2,300 years ago.
Jasper accessories and ornaments, which symbolized power at that time, served as the origin of the Komatsu brand and delivered to Kyushu through Japan-sea trading and at the same time, attracted the rulers of the Yamato Dynasty.
In the Kofun (Tumulus) Period, the forerunners of Komatsu started producing bracelets made of green tuff with elaborate detailed carvings. These ornaments then became popular in Japan, fascinating the rulers of the Yamato Dynasty.
