Hōkūleʻa, Hikianalia Make Landfall in French Polynesia

  • On June 25, anthropologist Yousuke Kaifu's team published studies in Science Advances recreating a 30,000-year-old sea crossing from Taiwan to Japan's Ryukyu Islands using a dugout canoe.
  • The project began in 2013 to answer how Paleolithic people reached remote islands like Okinawa and how difficult their journey was, testing hypotheses starting with raft attempts.
  • The team constructed a 25-foot dugout canoe called Sugime using tools authentic to the period and paddled approximately 140 miles across the challenging Kuroshio Current, all without the aid of modern navigation equipment.
  • Kaifu stated, “A dugout canoe was our last candidate,” explaining rafts were too slow and fragile, while canoes offered enough speed and durability but required skilled paddlers facing strategic challenges.
  • The project showed Paleolithic humans possessed advanced seafaring skills and endurance, suggesting ocean voyages were possible despite variable conditions, and that their journeys were more complex than previously credited.
