The tree limit on Mount Fuji is mainly composed of larches (Larix leptolepis) that are the dominant forest species there. The limit ranges from 1400 to 2900 meters, depending on the slope. On the western and northwestern slopes of Mount Fuji, where the forest vegetation reaches a high altitude, we have investigated the altitudinal changes of larch growth, e.g., tree height, diameters at breast height and ground level, buried seed number, and tree age. They were compared with some environmental factors, especially thermal condition. As a result, the following facts were concluded. The tree limit attained the 2900-meter altitude nearly 110 years ago on the western slope. The time period during which a tree limit ascends seems to be identical to the time period during which low-growth periods, that is, low-temperature periods occur frequently.
