In Shizuoka Prefecture, mainly in Shizuoka city, "Hiyoke",used to denote the quality of the tea crop, were fixed to the facade of houses involved in the tea industry. The purpose of this paper is to shed right on the character of architecture connected with the tea industry by focussing on the "Hiyoke". We found that "Hiyoke" were rarely used before 1894 but it became popular from around 1898 to the 1920's. It became clear that various matters such as the construction of the tea preparation factories, and legal regulations about the exportation of tea leaves etc., constituted the background against which "Hiyoke" became popular.
