is a comprehensive single-volume Japanese dictionary edited by , and first published by in 1988. This title is based upon two early Sanseidō 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). History 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. The second edition (1995) increased the number of entries to 233,000 and augmented the number of illustrations (including 31 pages of full-color maps and charts). Sanseido published the second edition in printed, CD-ROM, e-book, and Web versions. They additionally bundled the so-called "Super" version Sūpā Daijirin (スーパー大辞林) CD-ROM with other Sanseido Japanese and English dictionaries, plus pronunciation sound files. In 1997, Sanseido published a reverse dictionary of the second edition, entitled Kanji-biki, Gyaku-biki Daijirin (漢字引き・逆引き大辞林, ), with two indexes. The first lists kanji by on-yomi and stroke count, the second indexes headwords both by first and last kanji (for example, it lists jisho 辞書 "wordbook; dictionary" under both ji 辞 "word" and sho 書 "book"). According to Sanseido, total sales of the first two editions totaled over one million copies in 2003. The third edition (2006) added new headwords, such as the English loanword intarakutibu (インタラクティブ "interactive"), for a total of 238,000 entries. Japanese dictionary publishers have an ongoing dilemma, the increasing popularity of Internet and electronic dictionaries is decreasing the sales of printed ones. Kono (2007) notes, "According to Jiten Kyokai, an association of dictionary publishers, total annual sales of printed dictionaries, including popular Japanese and English, and specialized ones, such as technical dictionaries, halved to 6.5 million copies in the past decade." To promote the third edition, Sanseido launched a novel "Dual" service, the Dyuaru Daijirin (デュアル大辞林), allowing purchasers of the printed
