If you live in Japan or have visited Japan, what do you think of the fact that tipping is not part of Japanese culture? Tipping is normal in America and most parts of Europe, but in Japan people don't tip and, in fact, many Japanese people might consider tipping to be rude.
When someone gives you excellent service at a Japanese hotel, bar, or restaurant, or when someone delivers pizza to your hote/apartment, and you know they aren't being paid very much, do you sometimes wish you could give them a tip?
The ironic things about the no tipping policy in Japan is that the quality of service is actually higher in Japan than in many countries that do support tipping.
I have often wanted to give someone a tip while spending time in Japan!
