Features and collections

The collection of the Modern Japanese Political History Materials Room consists of three categories: "Modern Japanese political history materials," "Materials on the Allied Occupation of Japan" and "Materials on Japanese emigration."

Modern Japanese political history materials
Collections of private papers in and after the latter half of the 19th century. They comprise mainly diaries, letters, and drafts, once owned by political leaders, i.e. Cabinet Ministers, Diet Members, senior civil and military officers and others. Each collection bears its former owner's name.

Materials on the Allied Occupation of Japan
Collection of records of the U.S. Army and the U.S. Government, private papers and Japanese publications in microfilm concerning mainly the Allied Occupation of Japan in the post WWII period.
Most original records of this collection are in the custody of archives in the U.S. such as the National Archives and Records Administration (NARA), the Library of Congress (LC), the MacArthur Memorial, military document centers and universities' archives and libraries. Some microfilms were filmed by the NDL in the U.S. and the others were purchased from the NARA and other publishers.

Materials on Japanese emigration
Collection of books and periodicals published in the North, Central and South American countries, private papers in original and in microfilm, and government documents in microfilm related to Japanese emigration. The NDL has been microfilming documents which are in the custody of archives in those countries since 1985.
