I think it would be difficult to communicate with Japanese people because they have a unique culture, custom and language.
If you will explain your situation to me, I will provide specific advice about general communication, negotiations on business and so on between you and Japanese people.
Please ask me a question about the communication issues.
I will give an answer to your question.
For more than one question, please refer to gig extras.
I will provide a written answer to your question.
Please contact me for custom pricing.
I can deal flexibly with your request.
I will make a proposal if you need that.
Please feel free to contact me.
