The object of this paper is to provide some suggestions about an old Japanese technology and its two transfers. Tataki is an ancient plastering technique in Japan, and it was greatly improved for use in public works by Choshichi Hattori around 1880. From 1910, it was forgotten for a long time. However, it was rediscovered in the 1990's, resulting in two technology transfers. One is creating a new paving technology compatible with sustainability. The other is a transfer from Japan to Cambodia in restoring the temple foundation at Angkor Wat, in a revival of tataki. This paper presents a historical study, using data from recent academic papers and from interviews with the key persons. The results are as follows: (1) The elucidation of tataki's scientific mechanism played a very important role in both technology transfers. (2) Tataki could become a world-wide technology and could become the standard method for restoring heritage structures. (3) The new technology derived from tataki could be accepted from a viewpoint of sustainability.
