45 Japanese Life Rules That Are Hard for Foreigners to Understand
Japanese Don't Invite Friends to Their Home
Traveling across the waters to see a dear friend is such a big deal in any part of the world. And the hospitality shown by this host friend shows appreciation. But an invitation to the friend's family home might not be a part of this hospitality.

Privacy is held in high regard in Japan, and most Japanese would prefer to go out to the bar or dinner with friends. A foreigner should not be offended if they do not receive an invitation to visit their friend's home.
Don't Honk in Traffic
Metropolitan cities are common in developed countries. And these big cities come with their troubles. An example is the frequent traffic jam one encounters on the way to or back from work. And Japan is no exception.

But one thing that is not allowed here in Japan is honking in traffic. While in other parts of the world, it is seen as standard, it is believed to be a rude gesture to honk at another car in traffic. Patience is taught at its best here. Lovely!
