MSX-JE is a system to input Japanese characters and convert these to corresponding kanji or word. It appeared in 1986 on MSX-Write, a Japanese Word Processor released by ASCII. It was adopted in several programs thereafter. The MSX-BASIC v3.0 (and higher) supports MSX-JE.

The Japanese language has three forms of characters:

  • the Kanji are adopted logographic Chinese characters, they are used to write parts of the language such as nouns, adjective stems, and verb stems
  • the Hiragana are used to write inflected verb and adjective endings and as phonetic complements to disambiguate readings, particles, and miscellaneous words which have no kanji or whose kanji is considered obscure or too difficult to read or remember
  • the Katakana are mostly used for representing onomatopoeia, non-Japanese loanwords (except those borrowed from ancient Chinese), the names of plants and animals (with exceptions), and for emphasis on certain words.

Hiragana and katakana are both kana systems, they generally correspond to syllables while Kanji are ideograms, which express an idea, an concept, something that corresponds to the assembly of several kanas. This assembly is more easy in a Japanese Word Processor with the MSX-JE input system.
