Abarenbo Shogun S01 E73 A Man Passionate About the Snow on Mount Fuji

A kind but untalented kitchen-supervisor samurai is assigned to accompany his domain's gift to the Shogun: big blocks of ice. Shin-san, tramping around Shinjuku, accidentally discovers this delivery and starts accompanying it too, and discovers a rival domain is trying to kill the ice to humiliate the first domain.
