Asai

Asai is a Japanese surname that can be written with the characters 浅井, meaning shallow well. In that form, the name belongs to the long tradition of family names describing places and features of the landscape. Its history as a surname is distinct from its more recent use as a first name in English-speaking families.

The Japanese writing is important because a Roman-letter form does not always determine one exact set of characters or one meaning. Families using Asai for a different reason, such as a personal adaptation of another name, should not automatically attach the Japanese translation to it. The shallow-well explanation applies specifically to the established surname form. That gives Asai a clear documented route while leaving room to recognize individual family naming choices honestly.
