Why Did the Japanese Plum ‘Karari’ Originating from Taiwan Take Root in Amami Oshima?

In this presentation, we will examine why Japanese plum originating from Taiwan was able to take root on Amami Oshima. The Japanese plum ‘Karari’ (花螺李) was brought into Amami Oshima from Taiwan in 1935. Currently, ‘Karari’ is cultivated mainly in Yamato Village, where they make a significant contribution to the local economy as a specialty product. However, it is still unknown why ‘Karari’ took root in Amami Oshima including the environmental factors. Based on the results of fieldwork conducted in Yamato Village, we will discuss why ‘Karari’ took root in Amami Oshima.
