In 1981, the Japanese government published a list of the 1,945 basic Japanese kanji (Jooyoo Kanji-hyo), including specifications of pronunciation. This list was established as the standard for kanji usage in print. The database for 1,945 basic Japanese kanji provides 30 cells that explain in detail the various characteristics of kanji. Means, standard deviations, distributions, and information related to previous research concerning these kanji are provided in this paper. The database is saved as a Microsoft Excel 2000 file for Windows. This kanji database is accessible on the Web site of the Oxford Text Archive, Oxford University (http://ota.ahds.ac.uk). Using this database, researchers and educators will be able to conduct planned experiments and organize classroom instruction on the basis of the known characteristics of selected kanji.
