The Tempō Outlaws of the Marsh.

A great famine struck all of Japan: the so-called Great Tenpō famine. It was a time when there were frequent uprisings in rural areas due to farmers losing their land as a result of strict tax collection. The Tonegawa area of ​​Boso was a lawless area for a generation, as two major forces fought against each other: Sukegoro of Iioka, who wields power with his industrial capital behind him, and Shigezo of Sasakawa, a rising yakuza. Furthermore, the successive floods of the Tone River, which could be called fate, forced the farmers into even more poverty and despair. Meanwhile, farmers in Nabe Village continue to live a lethargic life, but agricultural reform is about to begin under the hands of Yugaku Ohara, a ronin who has settled in the village.
