“…The middle to late Eocene Fagus pollen occurs occasionally in the pollen profiles in the Ishikari Group and represents lower proportions (less than 5%) than other deciduous broad‐leaved tree pollen including that of Alnus , Quercus , and Ulmus‐Zelkova (Sato, 1994). The late Eocene to late Oligocene (28–23 Ma) pollen sequences in drill cores in the East China Sea off west Kyushu also show a lower representation (mostly less than 5% of the total pollen) of Fagus pollen than that in the Pliocene sediments (constantly >10%) (Iwata & Oshima, 2001).…”

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.
