JChar Converter is a simple JavaScript program which converts Roman alphabets to Japanese Hiragana/Katakana characters.

The conversion rule is based on "MS-IME 2000 Conversion Table" used on Windows operating system, "Kotoeri Conversion Table" used on Apple Macintosh system, "ATOK," which is another popular Japanese Input Method software, and Japanese traditional rules known as Hepburn System and Kunrei System.

JChar Converter supports only Hiragana and Katakana characters. It does not support Kanji (Chinese-based) characters.
