Kanji Modernizer is a fast, privacy-first tool for converting old Japanese kanji (Kyūjitai) into modern forms (Shinjitai). It runs entirely in the browser with no server or tracking, making it ideal for researchers, translators, designers, and anyone working with Japanese text. The UI highlights every converted character, supports JP/EN, and works instantly on any device. Part of the NicheWorks suite of lightweight, practical tools.








I'm also currently building a companion tool — an Old Kanji Reference page where you can browse and search all Kyūjitai characters. It’s still in progress, but the test version is already live here:
