The station opened on July 7, 1929, serving as a temporary end point for the newly constructed railway section between Shinkanuma and Shimoimaichi.
At the time, the local government area was called "Imaichi-cho"
Imaichi-cho was divided into three districts:
Kamimachi
Nakamachi
Shimomachi
The station was built in the Shimomachi district, which is why it was given that name.
