DESCRIPTION:During the 1st millennium BCE\, migrant communities from the K
 orean Peninsula entered Japan\, introducing an extensive culture package w
 hich significantly changed life within the archipelago. A substantial elem
 ent of this cultural package was rice and millet agriculture\; the dispers
 al of which occurred through a mixture of demic and cultural diffusion acr
 oss Japan. This process led to different responses amongst the  incumbent 
 population of complex hunter-gatherers\, the Jomon people. Some areas saw 
 marked delays in adoption compared with others in this new subsistence str
 ategy and in others the early adoption of farming was followed by reversio
 n to a predominantly hunting and gathering economy. The geographically div
 erse response to the introduction of rice and millet agriculture is genera
 lly assumed to be reflecting the underlying variation in the environmental
  and climatic settings of the Japanese islands. However\, this assumption 
 remains untested\, and further exploration of the relationship between env
 ironmental and social factors is required to illustrate the diversity of l
 ocal responses. This paper contributes to this research agenda by explorin
 g how environmental suitability for rice agriculture impacted the spatial 
 distribution of archaeological sites in the Yayoi period. We employ both m
 echanistic and correlative ecological niche models to elucidate on the sui
 tability of the environment of Japan to rice and the spread of agriculture
 . The mechanistic through modelling of temperature via the accumulated hea
 t unit growing degree days. The correlative through Bayesian species distr
 ibution modelling for Japonica rice using three distinct proxies for its p
 resence: paddy field sites\, charred remains of rice grains\, and stone si
 ckles The comparison and exploration  of these different lines of archaeol
 ogical evidence  will offer a robust inferential framework for reconstruct
 ing the ecological and cultural factors that promoted or hindered the diff
 usion of rice farming in prehistoric Japan. \n\nAll talks are hybrid\, to
