Also, please consider that you've been in Japan since you were 17, and began udjusting while you were still psychologically more pliable. Most of us who do a few years in Japan start a bit later than you.
Also, please don't fall into the trap of being insulted by everything. these days people have thin skins and allow themselves to be hurt too easily. If we all become offended so easily, then we'll live in a society in which it becomes ipossible to express opinions or share ideas. A sad direction in the modern world.
