And have you ever sought out what opinion Japanese Braille readers have of the system? Whether they find it "less than optimal"? I can't find the references right now but my memory from reading up on it at one time is that users were very happy with the system, that there is a fair amount of material transcribed into Japanese Braille, that it's quite easy to learn and that children become proficient readers faster than child learners of the regular writing system.
