There is a Japanese Moodle website here that seems to have a similar goal to ours, it's a Japanese demo and support site. It started in 2010 and has many recent posts here about the 2020 moot made by Tatsuya Shirai.
This site may be useful in promoting the ideas we are having here. I wonder if Tatsuya Shirai would like to get involved.
We might even be able to use it? Update it, add to it?
