General Tips While Making Calls to Japan

Before making calls, it is important to understand cultural etiquette in Japan to avoid inconvenience and ensure effective communication. Here are some important points you should consider:

  • Japan has a special greeting that is used during the beginning of a call - ''Moshi Moshi!"
  • Japanese people are very rigid when it comes to their business culture. So, make sure to call your vendors or partners during business hours.
  • Avoid calling your customer or partner during the early morning or lunchtime. Picking up a call in public transport is a major faux pas in Japan. So, avoid calling during the commuting hours.
  • Japanese people are private and reserved. It is better to avoid asking personal questions during the beginning of your business relationship.
  • Before making a call, it is a good idea to summarize everything you need to talk about in the form of a checklist to avoid spending more time on the call.
  • Try to avoid making calls outside of hours as much as possible, especially during the end of the day.
