Showa Shinzan is a remarkable natural phenomenon and a vivid symbol of Earth's restlessness. This young volcanic mountain, located in Hokkaido, near the serene Lake Toya, emerged dramatically in the early 1940s, providing scientists and the public an extraordinary opportunity to witness the birth of a mountain.

Unlike most mountains that have taken millions of years to form, Showa Shinzan's formation was witnessed in real-time by the local population during World War II. It rose from a flat wheat field following a series of seismic activities, growing rapidly amid earthquakes and eruptions. This unique origin story makes Showa Shinzan a fascinating subject for geologists and a captivating attraction for visitors.

Today, Showa Shinzan stands as an accessible yet powerful reminder of nature's dynamic forces. Visitors to the area can explore the Showa Shinzan Volcano Museum, which offers insights into the mountain's history and volcanic activity in Japan. The surrounding area, part of the Shikotsu-Toya National Park, is a haven for nature lovers, featuring hot springs, wildlife, and stunning landscapes.

For those intrigued by the forces that shape our planet, Showa Shinzan offers a rare glimpse into the process of mountain formation, making it a compelling destination for anyone interested in the wonders of the natural world.

A volcanic lava dome next to Mt. Usu. The peak is now 398meter and still actively smoking. This can be prove by no snow covered the peak as the surface are very hot, snow will melt and not stick on the surface. Had a nice lunch there and walking distance to Showa Shinzan bear ranch.

One of the youngest volcano from 1947. The load leading to the photo spot was quite slippery

Great day trip, the views and landscape are so beautifull, and to see the steam coming out from the mountain is mesmerizing. The ice cream we had from one stall tasted like yogurt instead of milk. Make sure you do the cable car to mt.usu aswell
