In 17th-century Japan, a diplomatic mission sets sail for the West. Among those facing the combined perils of the sea and foreign courts are ambitious Spanish missionary Pedro Velasco, and Hasekura Rokuemon, a disregarded samurai determined to recover his family's standing. They travel to Mexico City, Rome and back - but Japan's new rulers are persecuting Christians, and if the men survive the journey, they may not survive their homecoming. This true story of courage and endurance is told with Endo's signature power and simplicity.
