Sorry guys, but I have yet to come across any physical abuse from a Japanese instructor. The verbal abuse has been minimal, remember Japanese males speak very forcibly because that's the culutre, so what would appear to be a stern tone may well be just a very determined input. Remember, as the pilots online say, it's their train set!!
Yes, there is a higher attrition rate latelt, but that appears to be, no insult to anyone, because the package being offered is being ignored by the better experienced pilots who prefer to work elsewhere.
