I've been asked to explain what I mean by the Japanese having a poor teaching model for this. One friend of mine cautioned me that it appears racist.
We have too many Japanese and too many foreigners who spent decades in Japan who say the same thing for it to be racist. There are very well known Japanese teachers who admit it. This is the result of cultural norms. As one fellow-who got his under grad and grad degrees in Japan some decades ago- once opined "In six years of higher education do you know how many questions were asked in a Japanese classroom? Zero!"
