I was looking for a WordPress Plugin that helps proofreading for Japanese sentences. I think it is common wish for Japanese writers to fix conversion errors or to avoid discomfort expressions, but I couldn't find any WordPress Plugin to solve that problems. So I made and published this Plugin. I made the web page to describe what "Japanese Proofreading Preview" Plugin is. Please visit and see for details. http://mobamen.info/wordpress_proofreading I hope this Plugin will help somebody to improve the quality of Japanese sentences.
