Daijirin

Daijirin (Japanese: 大辞林^?, lit. "Great forest of words") is a comprehensive single-volume Japanese dictionary edited by Akira Matsumura (松村明^?, Matsumura Akira, 1916–2001), and first published by Sanseido Books (三省堂書店^?, Sanseidō Shoten) in 1988. This title is based upon two early Sanseido dictionaries edited by Shōzaburō Kanazawa (金沢庄三郎, 1872–1967), Jirin (辞林 "Forest of words", 1907) and the revised Kōjirin (広辞林 "Wide forest of words", 1925).

Sanseido specifically created Daijirin to compete with Iwanami's profitable Kōjien dictionary, which was a longtime bestseller through three editions (1955, 1969, and 1983). Two other contemporary dictionaries directed at the Kōjien market share were Kōdansha's color-illustrated Nihongo Daijiten (日本語大辞典 "Great dictionary of Japanese", 1989) and Shōgakukan's Daijisen (大辞泉 "Great fountainhead of words", 1995, also edited by Akira Matsumura).

The first edition of Daijirin (1988) had 220,000 headword entries and included encyclopedic content in numerous charts, tables, and illustrations. While Kōjien was printed in black and white, Sanseido included 19 two-color illustrations for topics like the seasons (with kigo), linguistics (synonymy), and Japanese language (Man'yōgana). According to Matsumura's preface, the process of editing the first edition took over 28 years.
