Abstract
A Japanese character processing system containing an on-screen keyboard which includes an array of base Japanese kana characters of a first kana character set. The first selection of a character key causes the display of the character in base kana form. A second consecutive selection of the same key causes the display of the character in a first variant form. Subsequent consecutive selections of the character cause the display of the character in further variant forms. Variant forms may include voiced, aspirated, or subscripted versions of the base character. A further variant form may include the display of the character in an alternate kana character set.
