Yep and in Japanese culture, tipping is considered rude. In Taiwan, it is rude to not offer to pay first after a lengthy meal with friends or family and tipping is not commonly observed. In the US, some Chinese restaurants will force you to tip with threats of violence (my personal experience while dining with family in a Chinatown restaurant, in lower Manhattan.)
