The surname Iwamoto is of Japanese origin. It is derived from two components: "Iwa" which means rock or stone, and "moto" meaning base or foundation. Therefore, the name Iwamoto can be roughly translated as "from a place with many rocks at its base."
It should be noted that Japanese surnames are traditionally patronymic, with the father's surname being passed down to the children. However, in the case of Iwamoto, it is likely that it originated from the name of a place, rather than being a patronymic surname.
The Iwamoto surname can be found throughout Japan and has many branches and variations due to the country's history of regional migration and clan affiliation.
