Japan's fruit tree production technology is in the world leading level. In order to understand Japan's fruit tree production, by through visits to Japan and data collection, this paper analyzes the changes in Japan's fruit tree cultivation area, regional distribution of fruit tree cultivation, main cultivars and market circulation in recent years. The results show that Japan's fruit tree cultivation area underwent great volatility in the 1980s and 1990s and it has been stabilized in recent years; the cultivation area of principal fruit tree is reduced, while the cultivation area of new fruit trees and characteristic fruit tree varieties is increased; the regionalization of fruit tree is obvious and the main cultivars are clear. Japan's principal fruit price goes through slight fluctuations during the year while the price of cherries and peaches goes through great fluctuations. It is concluded that Japan's fruit tree industry is stably developed.
