A children's novel about a boy whose father, a special attack pilot, died in May 1945, and who travels to a remote island in Kagoshima where his father's body is said to have washed ashore. Carrying the weight of his father's death and his young mother's hardship, he encounters island life and faces both the sorrow of war and the will to live.

A journey to the island tied to his father's death opens before the boy the memory of war and the life of the island.

A children's work by Hiroo Sakata with illustrations by Fuyuji Yamanaka. Centered on Grandpa Torajii, it expands the wonder and humor seen through children's eyes, along with encounters across generations, into a lightly told adventure.

An encounter with Grandpa Torajii sets an adventure in motion right beside everyday life.
