Human has made great progress beyond the speed of biological evolution by using tools. First, human used stones and wood as tools for hunting and gathering, and then invented earth-baked earthenware such as bowls for food, appropriate to farming life. The defects of woodenware and earthenware, however, were obvious. It was not able to contain liquid due to their moisture absorbency, and easily damaged. Earthenware has evolved into glazed ceramic but it required a high-tech kiln with high temperature, accompanied by a technology for metal refining as a key prerequisite. In East Asia, moisture proof and insect proof techniques to coat objects were invented much earlier. That is lacquer technique.\nProduction process of lacquer is delicate and complicated such as handling lacquer sap at the risk of skin disease, creating hot and humid environment for hardening process, etc. Nevertheless, in East Asia, people have used lacquer technique in many regions from the Neolithic Age, knowing its merits earlier on. Lacquer was used for adhesive and surface protection of leather, earthenware, ceramics and metalware. In particular, it has been inextricably linked to wooden objects. Whereas in West Asia and Europe various varnishes mixed with dry oil and resin has been used, in East Asia lacquer was used as a basic varnish in common. That shows that lacquer is great material and technique to represent the commonality of Asian culture.1) This article aims to briefly look into the origin of lacquer technique in Northeast Asia and share the information on it and its current status of transmission.

The role of intangible cultural heritage (ICH) as a guarantee for sustainable development has been recognized in the 2003 Convention for Safeguarding Intangible Cultural Heritage. The essence of ICH as a living heritage is anchored in the concept of sustainability wherein its practice, intergenerational transmission and re-creation influence its continuity among its bearers and practitioners. One of the safeguarding measures for ICH is through intergenerational transmission where one generation transmits their heritage to the coming generation as a mechanism to keep their heritage alive and thriving. Consequently, sustainability operates in a similar dynamic principle that assures for a development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
