Does japan have two daughters one gets killed and two sons one get killed?

Yes, in the context of the story of "The Tale of the Heike," a classic Japanese epic, there are tragic events involving two daughters and two sons of the Taira clan. One daughter, Taira no Tomomori's sister, is said to have died, and one of the sons, Taira no Kiyomori's son, also meets a tragic fate. This narrative reflects the broader themes of loss and the impermanence of life that are prevalent in Japanese literature.
