With the cultural differences between Japan and many Western countries, it is important to be aware of what may be considered offensive or rude in Japanese culture.

According to a blog post on Mobal.com, there are several key things that you should never say to a Japanese person. These include:

1. Do not address other people by their first names

In Japanese culture, it is considered rude to address someone by their first name unless you are very close to them. Instead, it is more appropriate to address them by their last name or with a title such as "san" or "sama". This shows respect and politeness, which are highly valued in Japanese society.

2. Do not ask personal questions when you first meet someone

When meeting someone for the first time in Japan, it is important to avoid asking personal questions such as their age, marital status, or income. These questions can be seen as intrusive and disrespectful. Instead, focus on more general topics of conversation until you get to know the person better.

3. Do not make direct eye contact

In Western cultures, making direct eye contact is a sign of attentiveness and respect. However, in Japan, prolonged eye contact can be considered aggressive or confrontational. It is better to show respect by lowering your gaze slightly when speaking with someone, especially if they are of a higher social status.

4. Do not criticize Japan or its culture

While it is important to be honest and express your opinions, it is not a good idea to criticize Japan or its culture when talking to Japanese people. This can be seen as disrespectful and insulting. Instead, focus on showing appreciation for the things you enjoy about Japan and its culture.

5. Do not refuse a gift or compliment

In Japan, it is polite to accept gifts or compliments graciously, even if you do not necessarily want or need them. Refusing a gift or compliment can be seen as rude or ungrateful. It is better to accept with a smile and a thank you, even if it is a small gesture.

Overall, when interacting with Japanese people, it is important to be aware of cultural differences and to show respect and politeness at all times. By following these guidelines of what not to say, you can avoid unintentionally offending or upsetting your Japanese counterparts.
