Why Japanese don't usually say I love you? Thank you for your understanding for my personal opinion. There is the word "omonbakaru" in Japanese. It is not so popular word, though. It means observing and feeling atmosphere and considering to surrounding. Asking and advocating with speech are sometimes felt other one to have no class and incomplete as person. I suppose this word much express to Japanese thinking. and, of course, as many over sea people know, This phrase is felt us simply shy.
