Kensuke’s Kingdom recap

After his parents lose their jobs, Michael joins them and his dog, Stella Artois, on a voyage around the world in the yacht Peggy Sue. A storm sweeps Michael and Stella overboard near the Pacific, and they wake on a remote island. An elderly Japanese castaway named Kensuke secretly feeds them, then forbids Michael to signal for rescue. Their conflict becomes friendship after Kensuke saves Michael from jellyfish and nurses him back to health. Kensuke explains that he was stranded during the Second World War and believes his family died at Nagasaki. When hunters threaten the island's animals, the two work together to protect them. Michael's parents finally find the island, but Kensuke chooses to stay and asks Michael to conceal his existence. Much later, Kensuke's surviving son contacts Michael after reading the published story, proving that the family Kensuke mourned had survived.

Michael's parents lose their jobs when their local brickworks closes. Rather than settle immediately into new work, his father proposes sailing around the world. The family buys a yacht named the Peggy Sue and learns to handle her, with Michael's mother taking navigation seriously and Michael helping with the many jobs aboard. Michael leaves school and his friend Eddie behind, promising to return with a story. His dog, Stella Artois, comes too. The first stages of the voyage bring hard work, seasickness, changing weather, and the strange experience of living together on a small boat surrounded by water. As they gain confidence, the journey becomes the family's new way of life.

The Peggy Sue carries the family across oceans and through a series of ports while Michael records the voyage in the ship's log. During a difficult night in the Pacific, Michael goes on deck with Stella and is swept overboard. He survives by clinging to his football and loses sight of the yacht. Michael and Stella eventually reach an island, but there is no sign of his parents. Thirst, hunger, and fear dominate his first attempts to explore. Fresh water and food begin appearing near him, suggesting that somebody else is present. Michael sees animals in the forest and senses an elusive human watcher, but he cannot yet understand who is sustaining him or why that person will not openly help him leave.

The island's other inhabitant is Kensuke, an elderly Japanese man who declares the place his kingdom. He has been leaving food and water for Michael and Stella, but he lays down strict boundaries and forbids Michael to light fires. Michael cannot accept a rule that prevents him signalling to passing ships. Their stand-off grows bitter as Kensuke extinguishes the fires Michael builds. Michael also resents being kept away from parts of the island and from the freedom to seek rescue. Defying warnings about the sea, he goes swimming and is badly stung by jellyfish. Kensuke rescues him and takes him to his shelter, shifting their relationship from distant hostility to direct dependence as Michael begins recovering under his care.

While Michael heals, he and Kensuke gradually learn to communicate. Kensuke shares food, teaches him about the island, and paints with materials he has made or preserved. Michael comes to understand the care Kensuke gives the orangutans and other creatures. Kensuke then explains his past: he had been a doctor and served aboard a Japanese ship during the Second World War. After the ship was destroyed, he reached the island and lived there alone. News of the atomic bombing of Nagasaki led him to believe that his wife and son had died, and isolation became the life he accepted. This history explains both his attachment to the island and his resistance to the outside world. Michael now sees him as a bereaved survivor rather than a captor, though he still longs for his own family.

Michael and Kensuke settle into companionship, caring for the island and watching young turtles make their dangerous journey to the sea. Kensuke becomes more willing to help Michael seek his family. Their peace ends when armed hunters arrive to kill animals. Michael and Kensuke hide with the orangutans and protect as many as they can until the intruders depart. Soon afterward they spot a yacht, and Kensuke helps Michael signal it. The vessel is the Peggy Sue, with Michael's parents aboard after their long search. Kensuke decides he cannot leave the island or the animals that depend on him. He asks Michael to keep him secret for ten years, and Michael returns to his parents. Long afterward, Michael publishes the story and hears from Michiya, Kensuke's son. Michiya and his mother survived Nagasaki, though Kensuke never learned that they were alive. Michael and Michiya meet to share what each knows of him.

When hunters arrive, Kensuke and Michael conceal themselves and the island's orangutans while the intruders kill other animals. The danger persuades Kensuke to help Michael attract a passing boat, but the boat proves to be the Peggy Sue: Michael's parents have survived and have continued searching for him. Kensuke decides not to leave. He believes his wife and son died at Nagasaki, feels responsible for the island's animals, and asks Michael to keep his existence secret for ten years. Michael is reunited with his parents and honors the promise. Years later, after publishing his account, he receives a letter from Kensuke's son, Michiya, revealing that Kensuke's family survived the bombing and that Michiya had long wondered what became of his father. Michael and Michiya meet, but Kensuke's own final fate remains unknown.
