**Introduction** CALLHOME Japanese Lexicon Second Edition (LDC2026L01) was developed by the Linguistic Data Consortium (LDC) and contains 80,688 Japanese words with morphological, phonological and stress information. This second edition updates file formats, directory structure and documentation. The first edition is available as CALLHOME Japanese Lexicon (LDC96L17). The CALLHOME series consists of telephone conversations, transcripts and lexicons developed by LDC and Rutgers, The State University of New Jersey, in support of research in speaker identification, language identification and related technologies. Languages in the series include American English, Egyptian Arabic, German, Japanese, Mandarin Chinese, and Spanish. **Data** The words in the lexicon were derived from 80 transcripts representing unscripted telephone conversations between native Japanese speakers contained in CALLHOME Japanese Second Edition LDC2026S02. The lexicon contains seven tab-separated information fields: (1) headword: orthographic form in kanji or katakana or hiragana (in only written in hiragana); (2) hiragana: orthographic form in hiragana; (3) romanization: orthographic form in romaji; (4) pron: pronunciation of the headword; (5) morph: morphological analysis of the headword; (6) train freq: frequency of the headword in the transcripts; and (7) gloss: glosses of the headword. The lexicon is presented as tab-delimited TSV file encoded in UTF-8 format. This release also includes a pronunciation dictionary derived from the lexicon in UTF-8 encoded CMUdict format and the grapheme-to-phoneme (G2P) tools used to automatically generate pronunciations for the original lexicon. **Updates** No updates at this time.
