Similar Syntax Search Function on Web Based Japanese Educational System

There are growing number of foreign people who are interested in learning the Japanese language. However, there are not enough teachers and courseware of Japanese education. One of the problems is a wide range of interests: daily conversations, business correspondences, technical documents, etc., which cannot be covered in a single courseware or a class. Making a textbook with a comprehensive set of sample sentences is also timeconsuming. Another problem is the number, shapes, and pronunciation of the characters used in the Japanese language, which would be an immediate barrier to start reading/writing Japanese text.
