Nihon kyôkaku-den (1964)

A timber merchant and haulage firm in late 19th century Tokyo is in trouble. The widowed lady owner is being threatened by a scheming competitor who is offering much cheaper labour. X has just left the army, and his buddies in the firm beg him to rejoin them as second in command, which he does. Thus emboldened, the firm tries to make a deal to stay in business, which launches a serious turf war.
