Abstract
We inferred that Japan provided a habitat for pine trees from the representative anthology of Japanese poetry written from the 8th to 15th century and threw light on the changes in the habitat occurring every century. People have acknowledged the value of the vegetation-covered landscape characterized by Japanese Black Pine trees on the beaches, because it is always referred to in poetry. In addition, the percentage of the vegetation-covered landscape characterized by Japanese Red Pine trees in the mountains increased rapidly after the 13th century. Association with wind sounds and the diversification of terms alluding to a mountainous habitat were regarded as the reasons.
