What should I do now? When should I give a gift? And should I do it at all? Can I take a shower when I want? And in general, can I move freely around the house?
If you have been visiting a traditional Japanese family and wondered about these questions, then the following rules of manners will be useful to you. That is not everything you need to know, but knowing and understanding at least a little will help you feel more or less confident when visiting the Japanese.

Meiwaku
In Japan, there is one very important concept, which underlies most of the rules - meiwaku. It can be translated from Japanese as “problems, anxiety, inconvenience that a person causes to people around him; violation of harmony”. Staying in a Japanese family's house is also a kind of meiwaku. With your presence, you violate the harmony of the house and bring anxiety and inconvenience to all its inhabitants. The most important rules: do not litter and respect family traditions. And if you want to do something - consult with the one who invited you.

Greetings
As soon as the owners of the house open the door for you, before saying hello, you must first apologize for the interuption. And the best phrase for you is お邪魔します (ojamashimasu), which means "I'm sorry to disturb you.".

Gift choice
You should think about a gift for the owners of the house in advance. It is best if the gift is related to your country. Souvenirs and goodies. An important point - the gift should be beautifully packaged. In Japan, people care about packaging.

Presentation of a gift
The gift is handed over almost immediately, as soon as you enter the house. When handing a package with a gift, hold it by the bottom with both hands - so that the recipient can take it by the handles. Giving a gift with one hand is disrespectful. Be sure to say すみません つまらない もの です が (sumimasen tsumaranai mono desu ga) when giving the gift, which means "Here's a little something for you.".

Bathroom use
If possible, it is better to find out in advance the routine of using the bathroom in this particular family. When you enter the house, you will definitely be shown and told what and where is located. At this point, you can ask this question. Usually in the evening, the guest is offered to take a bath first, which you will be informed about.

Food
It is not worth going down to the dining room without permission, so as not to disturb other family members with your presence. Do not disturb the inhabitants of the house, do not wander around the house if you are not called, and do not pester other family members with empty talk.

Leaving
When you say goodbye to a Japanese family, don't forget to thank the hosts for their hospitality. You can do this with the phrase: いつも お世話になって, どうもありがとう ございました。 (Itsumo osewa-ni natte, doumo arigatou gozaimashita), which literally means you always took care of me.

The Japanese do not often invite guests to their homes. And if you were invited, then you are given a great honor. For the Japanese family itself, if they had no experience of communicating with foreigners before, seeing you in their home, although troublesome, is at the same time curious and even pleasant.

Similar rules are not used in all Japanese families. Perhaps in another Japanese family and in another city, everything will be a little different. For example, in families that often host foreigners at home, you may not feel like you are delivering "meiwaku" at all.

Did you know ? you are not allowed to wear a shoes inside the Japanese house.
you must take off your shoes and when you take off your shoes you have to point them towards the door as
it's consider to be the proper manners.
Be sure to show your manner if you went to some one's House in Japan.
