Fig. 1. — Map to illustrate geographical relations in early Japanese history. Numbers 

 indicate the main cultural foci: 1, northern Korea (the kingdom of Chao-hsien is 

 here shown in its later stages, earlier it extended across the Yalu basin) ; 2, 

 southern Korea ; 3, Kyushu ; 4, Izumo ; 5, Yamato. Letters have reference to 

 successive Ainu frontiers. The conquest and absorption of the Ainu had pushed 

 the Yamato frontier as far eastward as the Lake Biwa region (A) before the close 

 of the prehistoric period. The line B-B represents the next great advance, just 

 at the dawn of the historical period, and C-C the frontier as it existed about the 

 time of the loss of the continental possessions of the Yamato. The line D-O 

 was reached by the Japanese about the beginning of the eighth century, and the 

 occupation of the main island may be regarded as completed. In its broad out- 

 lines, by the close of the tenth century. Scale of map approximately 1 : 22,500,000
