Kanikousen

Hakukomaru (博光丸) is the name of the fisher ship that seals the cold and dangerous waters of the Russian peninsula of Kamchatka, always followed by an escort of Japanese Army. At board travel the workers who have to catch and tin crabs, hopeless and exploited until unimaginable limits by a cruel patron. It's a fiery critic against capitalism originally written as a novel by Japanese communist party member Takiji Kobayashi.
