There is a rich beech fossil record in Japan dating from the Paleogene to the Holocene, which allows for the continuous tracing of the evolutionary history of the genus and allows us to understand the environmental background that facilitated the genus to obtain a dominant state in present-day forests. In addition to the temperate climate, the oceanic climate was an important factor in controlling beech distribution and dominance in the forests in Japan. With the cooling climate, beech species began expanding their distribution in the Northern Hemisphere in the middle Eocene and appeared in Japan in the late middle Eocene. Beech species became dominant in forests in Japan during the Miocene along with the development of the oceanic climate by the opening of the Sea of Japan and with the strengthening of the monsoon. Fagus crenata appeared until the Late Pliocene and became dominant in forests in central Japan in the late Early Pleistocene coinciding with the onsetting inflow of the Tsushima Warm Current to the Sea of Japan in interglacial stages. During the full-glacial stages since the late Middle Pleistocene, the cold and dry climate caused by the strong winter monsoon limited the distribution of beeches into refugia at humid places, including the inland. During the deglaciation since ca 19 ka, the beech population began to grow and its distribution expanded, controlled by the development of the Tsushima Warm Current, as well as latitudinal and altitudinal temperature clines.

“…Sado Island (Matsue & Nasu, 1997;Nguyen et al, 1998) and the Hachirogata site (Yoshida & Takeuti, 2009) yielded 25% and 5% (Figures 4c and 5c) Cryptomeria pollen at 12,000 cal BP, respectively. These results suggest that the coast of the Tohoku region facing the Sea of Japan also served as refugia for small populations of C. japonica during the LGM.…”

The natural distribution of Japanese cedar (Cryptomeria japonica) has been disturbed by human activities, owing mainly to its value as timber; thus, its position in the vegetation zone of Japan is not clear. Therefore, it is important to determine the history of C. japonica forests before human influence. We reviewed the transitions in distribution and abundance of C. japonica in the Japanese Archipelago since the last interglacial period by using published pollen data. During the last interglacial, temperate deciduous broadleaf forests developed on northeastern Honshu Island, whereas on southwestern Honshu Island C. japonica populations increased, accompanied by warm-temperate evergreen broadleaf trees. During the first half of the last glacial period, C. japonica forests developed throughout the Japanese Archipelago except on Hokkaido. Thereafter, 60,000-30,000 years ago, C. japonica covered the area around Lake Biwa and the Izu Peninsula. During the Last Glacial Maximum, C. japonica was most abundant on the Izu Peninsula, and small refugial populations were located along the coast of the Sea of Japan from southwestern to northeastern Honshu, and along the Pacific coast of Shikoku Island. During the Middle Holocene, C. japonica populations increased rapidly in southwestern Honshu. Two thousand years ago, before the intensification of human activities, C. japonica was widespread in warm-to cool-temperate zones on the Sea of Japan side of Honshu, the Izu Peninsula, the Pacific coast of Shikoku Island, and Yakushima Island. This evidence indicates that C. japonica is one of the major tree species in the Japanese vegetation zone.
