When Fumio and Yusaku are about to depart to Manchuria, Fumio mentions "Here we go to settler's paradise". This refers to the propaganda regarding the massive migration program undertook by the Japanese government called "Millions to Manchuria" that sent hundreds of thousands of peasants to settle and colonize the rural areas of northern Manchuria (Manchukuo at the time).
The film was part of the line-up at Toronto Japanese Film Festival (TJFF) in Toronto, Canada in 2021.
