Ageya type burin was firstly derived from Ageya site in Ngano prefecture. After the first report by Morisima, many burins characterized as a similar technological feature has been found from other sites mostly in Kanto region. Simohara and Fujimicho site is located near the Nogawa river. Many Upper Palaeolithic sites are known around that region. 17 burins and 2 blanks of the burin were found by excavation of this site. Those Burins have almost all the same technological features to Ageya type burin, but one feature is different. In this report, I compare the technological feature of these burins with Ageya type burin, and discuss the reason why one feature is different.
