What is moshi moshi?

"Moshi Moshi" is a common Japanese greeting used when answering the phone. It is a casual way of saying "hello" and is typically used in phone conversations. The phrase is derived from the verb "mōsu" (申す), which is a humble form of "to say," and it's repeated for emphasis.

The use of "moshi moshi" is specific to phone communication and is not used in face-to-face greetings. There are several theories about its origin, one being that it was used by telephone operators in the early days of telecommunication in Japan to ensure the line was clear and the call was connected. Over time, it became a standard way for people to start a conversation when answering a call.

Aside from this phone greeting, "moshi moshi" has also been used in popular culture globally, appearing in songs, brands, and as a restaurant name, often to give an international or Japanese flair.
