Today in History (J)20th Century Quiz (J)

"The World and Japan" database project consists of three under construction databases funded by grants-in-aid from Japan's Ministry of Education, Culture, Sports, Science, and Technology (Monbukagakusho) and Japan Society for the Promotion of Science(Nihongakujutsushinkoukai). The purpose of this home page is to disseminate the interesting outcomes of this on-going project. Three databases are available:

    "Japanese Politics and International Relations" (English, Japanese)
"Chronology of the 20th and 21st Centuries" (Japanese only)
"Abbreviations for International Relations" (Japanese only)

Although all databases may be used for private purposes, official approval is required in advance if any part of the data is to be reproduced in print, electronic media, or in any other form. Applications for approval can be made via the e-mail account shown below. Reproduction of the entire contents of any database is strictly prohibited.

Outline of databases

"Chronology of the 20th and 21st Centuries" (Japanese only) updated 1/9/08
15,826 new entries have been added since April 1st, 2007; in total there are 233,962 entries covering 1900 to December 2006.

The "Chronology of the 20th and 21st Centuries" database covers world and Japanese domestic affairs from 1933 to 1994. This database was originally named "General Chronology of Postwar Japan" and was available on this web site until March 1993. The "General Chronology of Postwar Japan" database was supported by Monbusho grants-in-aid for "Basic Research on the Formation of Postwar Japan" from 1992 to 1994 and by Monbusho grants-in-aid for "Publicizing Research Outcomes" from 1995 to 1997. Both projects were headed by Akio Watanabe.

The "Chronology of the 20th and 21st Centuries" database is the expanded version of the "General Chronology of Postwar Japan." This project was supported by Monbusho grants-in-aid for "Publicizing Research Outcomes" in 1998. This project is headed by Akio Watanabe and contributed to by Akihiko Tanaka, Naoto Nonaka, and Shiro Harada. Our aim is to produce a chronology covering 1901 to 2001. This database is, we believe, one of the most comprehensive and user-friendly databases available for the 20th and 21st Centuries.

Using this database, you can make your own chronology by indicating a certain period and/or search words. Each search is a full text search of each event in the chronology. You can search the events by entering words that might appear in the chronology or by entering country names even if the names would not appear in the event field. For example, if you enter "Nihon" (in Japanese), you can find all the events concerning Japan. A list of countries used in this "hidden country name field" can be viewed here (J). You can also search for events by entering a certain period or a specific date. The bibliography of this chronology can be viewed here (J).

Although all data have been checked thoroughly for historical accuracy, some uncertainties and inconsistencies remain. This data can be viewed here (J). We would be very grateful for information that enables us to rectify any inaccuracies or inconsistencies.

"Japanese Politics and International Relations" (English) (Japanese)

This database consists of basic documents for studying the international relations of Japanese politics mainly after WWII. In addition to these basic documents, this database includes prime ministerial addresses to the Imperial Diet before WWII as well as addresses in and outside of the National Diet after WWII. Also included are addresses of the Ministers of Foreign Affairs, Ministers of Finance, Secretaries of Economic Planning Agency, Japanese representatives to the UN General Assembly, and Summit-related documents. In this database, you can also find many important WWII documents.

This database was supported by Monbusho grants-in-aid for "Basic Research on the Formation of Postwar Japan" from 1992 to 1994 headed by Akio Watanabe, and by grants-in-aid for "Publicizing Research Outcomes" from 1995 to 1998 headed by Akihiko Tanaka, and contributed to by Akio Watanabe, Susumu Yamakage, Shinichi Kitaoka, and Naoto Nonaka. Until 1998, this database only included the addresses that were delivered inside and outside the Diet and was called the "Database of Japanese Ministerial Addresses." In 1998, other documents were added making this database more comprehensive.

"Abbreviations for International Relations" (Japanese only)

The abbreviations database emerged from the making of the "Chronology of the 20th and 21st Centuries" database. This database is still a work in progress. In particular, the original names of many of the abbreviations have yet to be confirmed. Users should feel free to contact us if they notice any mistakes.

In spite of the utmost care taken in constructing these databases, we cannot be certain that all mistakes, including incorrect or omitted words, have been eliminated. We do not assume any responsibility for trouble caused through the use of these databases. Nevertheless, in order to improve the quality of the data provided, we would be very grateful for any information regarding inadequacies that users may notice.

We regret that we cannot answer substantive reference inquiries.

I wish to express my thanks to the many people who contributed to this project. Without their efforts the compiling of these databases would not have been possible. (Akihiko Tanaka)
