The present revised edition of the "History of the Empire of Japan" (compiled, in 1893, for the Imperial Japanese Commission of the World's Columbian Exposition at Chicago, by Messrs. K. Takatsu, S. Mikami, M. Isoda, and others, and published in Tōkyō by order of the Department of Education) is not intended to supersede the original edition, the high qualities of which are, on the contrary, recommended to all students of Japanese history. That work admirably represents what might be termed the orthodox view of the national history, and is free alike from the unscientific method of the more conservative historian, and from the superficial speculations of the more radical, but not more scientific, student. Were the present editor to write an original work on Japanese history, however, he would, it is unnecessary to say, change the entire manner of presentation in order to make it accord with his own conception of the subject-matter. In this revision, he has not changed the general order of the original work, but has merely corrected a few data which are obviously out of date, omitted those minor facts which may well be dispensed with, and made the general narrative somewhat smoother than it was. The fourth part is, however, the editor's own work. The primary aim in this division of the volume has been to supply a popular and accurate account of certain phases of the national progress that has taken place since the "History of the Empire" was prepared a dozen years ago. The substance of chapter XVIII has appeared among the new chapters supplied by the editor to the new edition of Brinkley's (edit.) "Japan," (J. B. Millet Co., Boston, 1905), and has been inserted here with the permission of those publishers. K. Asakawa YALE UNIVERSITY INTRODUCTION The Empire of Japan consists to-day of a group of islands marshaled in the northwest corner of the Pacific Ocean, off the eastern coast of the Asiatic continent. These islands--including Formosa and the Pescadores ceded by China in 1895, and the southern half of Sakhalin, acquired from Russia in 1905--lie between the parallels of 50° 56' and 21° 48' north latitude, and the longitude of their extreme eastern and western points are 156° 32' and 119° 20', respectively, east of Greenwich. The empire thus covers 29° 8' of latitude and 37° 12' of longitude. On the east it faces the Pacific; on the southwest it looks across the waters of the China Sea to the mainland of China; on the northwest the Sea of Japan and Gulf of Tartary separate it from Korea and Siberia. The fiftieth parallel divides the Japanese half of Sakhalin from the northern or Russian half, and the Kurile Strait intercepts the Chishima or Kurile group of islands on the north from the Russian peninsula of Kamchatka.
