Researchers Uncover Ancient Seafaring Techniques in Taiwan-Japan Journey

In a groundbreaking study, a team of researchers led by Professor Yousuke Kaifu from the University of Tokyo has successfully recreated a 30,000-year-old ocean journey that early humans undertook from Taiwan to Japan using primitive canoes. This research not only sheds light on ancient maritime navigation but also enhances our understanding of human adaptability and innovation in prehistoric times.

The journey, which occurred around 30,000 years ago, involved navigating the vast and perilous waters of the Kuroshio Current, one of the strongest ocean currents globally. This expedition raises critical questions about how early modern humans managed to traverse such challenging maritime routes without the aid of maps or modern navigational tools.

According to Professor Kaifu, the project aimed to answer fundamental questions regarding the capability and strategies of Paleolithic peoples in reaching remote islands like Okinawa. "We initiated this project with simple questions: ‘How did Paleolithic people arrive at such remote islands as Okinawa?’ and ‘What tools and strategies did they use?’" Kaifu stated.

To test their hypotheses, the researchers employed a hands-on approach, relying on experimental archaeology. They constructed traditional-style dugout canoes, including a 24-foot (7.5-meter) vessel named Sugime, crafted from a single cedar log using replicas of ancient stone tools. In 2019, the team paddled the canoe 140 miles (225 kilometers) from eastern Taiwan to Yonaguni Island in Japan, completing the journey in over 45 hours of continuous paddling, often without visual land markers.

Dr. Yu-Lin Chang, an oceanographer at the Japan Agency for Marine-Earth Science and Technology, played a pivotal role in the project by conducting computer simulations to explore various oceanic conditions and strategies. These simulations revealed that starting the journey from northern Taiwan significantly increased the likelihood of a successful crossing. The research also indicated that adjusting the paddling direction slightly southeast could counteract the strong northern drift caused by the Kuroshio Current.

"The Kuroshio Current is generally considered dangerous to navigate. However, our simulations showed that with the right strategies, it was possible for early navigators to succeed," Dr. Chang remarked. The researchers concluded that while these ancient seafarers demonstrated remarkable skills, the journeys were likely one-way trips, given the lack of navigational aids for a return journey.

This study not only enhances the understanding of ancient human migration but also highlights the ingenuity and resourcefulness of prehistoric peoples. Professor Kaifu emphasized the implications of their findings: "Our Paleolithic ancestors were real challengers. They undertook strategic challenges to advance, similar to us today."

The broader implications of this research extend to understanding human migration patterns and adaptability in harsh environments. The study reinforces the notion that early human societies possessed a sophisticated understanding of their surroundings and navigational strategies, akin to the ancient Polynesians who traversed vast Pacific waters without maps.

In summary, this research provides profound insights into the capabilities of early humans and their remarkable spirit of exploration, which continues to resonate in modern society. The findings encourage a reevaluation of how we perceive ancient human achievements and their enduring legacy in our understanding of human history.
