She was adapted to be a passenger ship and renamed as Kasato Maru and transported the soldiers who had fought in Manchuria back to Japan.

Some Japanese immigrants arrived at Brazil before Kasato Maru, founding an agricultural colony in the current municipality of Conceição de Macabu (then district of Macaé), in the state of Rio de Janeiro.

However, it was the arrival of this first group brought by Kasato Maru that initiated a continuous flow of immigration from Japan to Brazil.

Some of the Kasato Maru's passengers continued to Argentina (see es:Café El Japonés).

Kasato Maru then sank into the Bering Sea in the Soviet waters near the Kamchatka Peninsula.
