Mikasa City Museum, Fossil museum in Mikasa, Japan.
The Mikasa City Museum is a fossil and city museum located in Mikasa, a small town in Hokkaido, Japan. Its collection focuses on ammonites and other marine creatures from the Cretaceous period, all discovered in the surrounding area.
In 1976, the skull of a Cretaceous marine reptile was found in the area, drawing scientific attention to the region. The museum opened in July 1979 to house this find and the growing number of fossils being uncovered nearby.
Ammonites have become familiar to many Japanese visitors through anime and manga, and the museum reflects this by mixing scientific displays with references to popular culture. Walking through the rooms, you can notice how fossils that are millions of years old feel surprisingly close to everyday life.
The museum is within walking distance of central Mikasa and keeps regular hours most days of the week. It is worth checking in advance whether guided tours or audio guides are available in your language.
One of the ammonites on display measures about 1.3 meters across, making it one of the largest specimens ever found in Japan. Standing next to it gives a clear sense of just how big these animals could grow.
