A Deep History: From Emperors to the Edo Period
The history of Mifune is deeply intertwined with the evolution of Japan. The area was once part of the ancient Higo Province and served as a backdrop for several significant conflicts, including battles during the Nanboku-chō period, the Sengoku period, and the Satsuma rebellion.
The town's very name is rooted in folklore. According to legend, Mifune is the location where the ship of Emperor Keiko—a ruler from the Kofun period (a period of Japanese history characterized by large burial mounds)—was docked during his time in Kyushu. During the Edo Period, the town flourished as a mercantile center under the administration of the Kumamoto Domain. Following the Meiji Restoration, the modern municipality of Mifune was officially established on April 1, 1889.
Paleontological Breakthroughs
One of Mifune's most significant claims to fame is its contribution to the field of paleontology (the study of fossils). In March 2014, a piece of sandstone was discovered in the town containing a tooth dating back to the Late Cretaceous period, approximately 90 million years ago.
This find is monumental, as it is considered the oldest tooth ever discovered in Japan. Researchers believe the specimen is a back tooth from the upper left jaw of a carnivore. It is thought to be similar to a Deltatheridium, an ancient relative of marsupials that inhabited what is now Mongolia between 145 and 66 million years ago. To further its scientific mission, the town and the Mifune Dinosaur Museum maintain a partnership with Montana State University's Museum of the Rockies.
