本文分别对日本列岛（北海道、本州-四国-九州和琉球群岛）三个地理区末次冰期和全新世的陆生哺乳动物区系作了简要描述。并概述了这一时期陆生哺乳动物的迁徙和迁入情况。在北海道，末次冰期的动物群仅由少数灭绝的大型哺乳动物物种代表。据推测，猛犸动物群在这一时期从东西伯利亚迁移到北海道。末次冰期的大型哺乳动物物种可能在全新世开始时灭绝。北海道的全新世动物群与现代动物群几乎相同，全新世期间没有哺乳动物迁入北海道。在本州-四国-九州，末次冰期动物群主要是现在分布在该地区的现存物种，并包含几个灭绝的物种以及几个现存的物种，现在外来的这个地区。灭绝的外来物种似乎在大约两千年之间已经灭绝。20，000和CA。放射性碳年代为10,000年前。在末次冰期，少数猛犸动物群从北海道迁移到本州-四国-九州。据推测，这种有限的移民是通过横跨津轻站形成的临时冰桥而不是稳定的陆桥发生的。在本州-四国-九州，全新世动物群与现今动物群几乎相同，在全新世期间没有哺乳动物迁入该地区。琉球群岛末次冰期动物群为岛屿型，以中小型鹿为主体的动物群可能在全新世初期灭绝。末次冰期和全新世没有哺乳动物迁入。
This paper concisely describes the land mammal faunas of the last glacial period and Holocene separately for the three biogeographic regions comprising the Japanese Islands (Hokkaido, Honshu-Shikoku-Kyushu and the Ryukyu Islands). It also outlines the extinctions and immigration of land mammals during the periods. In Hokkaido, the fauna of the last glacial period is represented only by a few extinct large mammal species. It is inferred that the Mammoth Fauna immigrated from eastern Siberia into Hokkaido during this period. The large mammal species of the last glacial period became extinct possibly by the beginning of the Holocene. The Holocene fauna of Hokkaido is almost idenfical with its present-day fauna, and no mammals immigrated into Hokkaido during the Holocene. In Honshu-Shikoku-Kyushu, the last glacial fauna is predominated by extant species now distributed in this region, and contains several extinct species as well as several extant species now exotic to this region. The extinct and exotic species seem to have become extinct between ca. 20,000 and ca. 10,000yrsBP in radiocarbon age. During the last glacial period, few elements of the Mammoth Fauna immigrated into Honshu-Shikoku-Kyushu from Hokkaido. Such limited immigration is inferred to have occurred through temporary ice bridges formed across the Tsugaru Stait instead of a stable land bridge. In Honshu-Shikoku-Kyushu, the Holocene fauna is almost identical with the present-day fauna, and no mammals immigrated into this region during the Holocene. In the Ryukyu Islands, the last glacial fauna is of insular type, and its main elements including middle- and small-sized deer became extinct possibly by the beginning of the Holocene. No mammals immigrated into the Ryukyu Islands during the last glacial period and Holocene.
