One of the reasons why I like this forum is that I can input Japanese characters and readers can access these if their computers have a Japanese language capability. I have recently responded to a question about the meaning of 'Morihei' and other names. To have to transcribe the Chinese characters into an acceptable roman system is a chore, but I think it helps to be able to print the Chinese characters.
Members often ask for the meaning of the names of techniques etc and this part of the forum is the obvious place to post answers to these questions.
In my opinion, the Japanese language forum as such (i.e., the section below the main menu giving various languages) is for discussions conducted in Japanese and I would be more than happy to participate, for it would be good for me to practise my written Japanese. But I think the number of posters and visitors would not be very great.
