THE group of islands forming Japan may be said to have routes of communication with the continent of Asia at six places: two in the north; two in the southwest, and two in the south. The principal connexion in the north is across the narrow strait of Soya from the northwest point of Yezo to Saghalien and thence to the Amur region of Manchuria. The secondary connexion is from the north-east point of Yezo via the long chain of the Kuriles to Kamchatka. The first of the southwestern routes is from the northwest of Kyushu via the islands of Iki and Tsushima to the southeast of Korea; and the second is from the south of the Izumo promontory in Japan, by the aid of the current which sets up the two southern routes. One of these is from the southwest of Kyushu via the Goto Islands to southeastern China; the other is from the south of Kyushu via the Ryukyu Islands, Formosa, and the Philippines to Malaysia and Polynesia. It has also been proved geologically* that the islands now forming Japan must at one time have been a part of the Asiatic continent. Evidently these various avenues may have given access to immigrants from Siberia, from China, from Malaysia, and from Polynesia.

*There have been found in the gravel Tertiary mammals including elephas primigenius, elephas Namadicus, stegodon Clifti, and unnamed varieties of bear, deer, bison, ox, horse, rhinoceros, and whale. (Outlines of the Geology of Japan; Imperial Geological Survey).
