Every country has its list of "taboos" and Japan is no different. Here's a great new wacky Japanese T-shirt showing some things you should avoid doing in Japan: sleeping with your head pointing to the north, putting chopsticks straight up in rice (both related to Japanese funerals), and entering a house with dirty shoes on. This bizarre new shirt helps you keep these in mind. Also, it's very rude to commit ritual disembowelment (hara-kiri), so the back of this shirt lists this important information, too. Remember to mind your manners when in Japan! A great new "warning" shirt that will get you lots of attention, back by popular demand!
