What is the secret behind Wajima-nuri’s durability that allows it to last for centuries?

Using state-of-the-art technologies such as high-precision 3D scanning capable of micron-level analysis, we conducted an in-depth investigation of the lacquer coating’s cross-section.
By analyzing ultra-thin lacquer layers measuring just a few thousandths of a millimeter, we uncovered a series of astonishing findings.

This marks the world’s first attempt at such a comprehensive analysis of Wajima-nuri.
