Jim and fellow Sea Hunter Mike Fletcher interview Dr. Torao Mozai, the "father of underwater archaeology" in Japan, while filming at Takashima, site of the Mongol Invasion of 1281. In the early 1980s, Dr. Mozai and his team discovered the first traces of the invasion fleet, sent by Kublai Khan to subjugate Japan and lost to what Japanese legend calls a divine wind or "kamikaze" that destroyed the invading ships.
