The application of Kira's Warmth Index (WI) 15 to the forest limit was tested in mountains of Hokkaido. Forest limits were hardly dependent on WI15 or on any definite WI value, but generally correlated with the altitudes of the mountains. The forest limits were located normally in the region of 200 m to 500 m lower than the summit of the mountain. The north-westerly seasonal wind in winter was considered as the most prevailing factor controlling the forest limit.
