This paper aims to investigate the relation between the raft's size and common heights of town house's eaves in Kyoto under Tokugawa regime. The Standard of town house's eaves were 4242 mm or 4545 mm called “joshi” or “jogo”. In precede studies, these size were come from rafts size flowing on the Hotsu-river (Ooi-river or Katsura-river). But, these rafts were made by timbers adjusted by “Rokushakusao” (1818 mm measure) and town houses were made by timbers adjusted in “Kyoma” (1965.5 mm measure). After all, there was no evidence about direct participation.
