7. Don’t wear shoes in the house: In Japan, people aren’t allowed to wear shoes in their homes. You will need to remove your shoes before entering a house. There is a place called genkan in their houses. You will have to remove your shoes and wear the provided slippers. But, to enter their tatami mat room, you have to remove your slippers also. They don’t normally allow dust into their clean rooms.
8. Stop spreading the germs: Japanese people usually make use of surgical marks to avoid spreading their cold or flu germs. They are keenly cautious about their sickness. In most cases, they also don’t sneeze in public and use a fresh tissue every time they wipe their noses. They don’t spread germs and they try to ensure other people are being safe and healthy.
9. Avoid the number 4: For many the number 13 is unlucky but in Japan, it is the number 4. This number has the same pronunciation (shi) as death in Japanese. They also avoid number 9 (kyo). To them, these numbers are unlucky. There are several hotels and seats which skip these numbers. Therefore, maybe you should avoid walking around in your San Francisco 49ers t-shirt while visiting Japan.
10. Don’t forget the toilet slippers: There is one more custom in Japan that can be really confusing. They make use of an entirely different pair of slippers for their toilet usage. You need to always make use of those exclusively for the toilet. Also, you shouldn’t forget to change back in your own house slippers. Otherwise, it may look like an offensive action.
The Japanese people have a generous heart and obviously they are good-natured people. Japanese will never be rude if you have made any of the above mistakes but it is noteworthy to still learn how to follow their cultures and customs if truly you are planning on visiting them.
