The Hokulea was built in 1975 which is more than thirty years ago from now and sailed from Hawaii to Tahiti in the following year by watching the stars and waves using an ancient navigation method. Moreover, also in 1975, the Chechemeni using ancient navigation came to the Okinawa Ocean Expo from Satawal in Micronesia. Thirty years have passed since then, but there are canoes and great navigators even now in Micronesia. I wonder what the impact of ancient navigation and canoes on contemporary people.
