Folktales from Japan
The Medicine That Works Here and There; The Monster Master; The Frog of Kyoto, the Frog of Osaka (5x46)

A woman wants a drug to slowly kill her mother-in-law. An old man is terrible to his servants, even when those servants are monsters (this tale is a renewal). A frog from Kyoto and a frog from Osaka visit each other's cities.
