An exciting and fun way to learn!!

Welcome to Gamadasu dome.

From November 1990, our volcano was active for about five years. How did the local people overcome this disaster? The Gamadasu Dome has undergone renovations and reopened in April 2018. Here we hope that you will be able to learn about the wonders of nature, the lessons that we have learned from the disaster, how to prepare yourself in case of a disaster and learn even more about the geopark.

Through projection mapping you can see how the pyroclastic flows and rockslides affected the area over the five years of volcanic activity.

Wonder lab

To learn about science, geoparks, and disaster prevention; there is an area where guests can participate in experiments and other experiences.

Café and Shopping

The people of the Shimabara Peninsula have received many gifts from the land. In order to convey these gifts, the Gamadasu Dome has two main concepts. They are,“the importance of life in the present”and “the warmth of the people.”In these concepts the themes are“life”and “people”and we hope that this helps to convey the “heart”of the Shimabara peninsula to our visitors.
