Natural Freedom

Grass-eating boys' commitment phobia is not the only thing that's worrying Japanese women. Unlike earlier generations of Japanese men, they prefer not to make the first move, they like to split the bill, and they're not particularly motivated by sex. "I spent the night at one guy's house, and nothing happened—we just went to sleep!" moaned one incredulous woman on a TV program devoted to herbivores. "It's like something's missing with them," said Yoko Yatsu, a 34-year-old housewife, in an interview. "If they were more normal, they'd be more interested in women. They'd at least want to talk to women."

now I'm strarting to think that the reason most Japanese women are so nice is because Men in Japan don't really care about them and don't chase them- so unlike western women, they are not used to getting attention all the time.

From what I've seen [the image of] women are sexualised over there just the same as in Western countries, I think this 'nice' behavior is just social conduct.

Maybe you should visit a country with a multicultural population and you'll see it's probably not all that different from where you live, you even saw that for yourself in Thailand.
