Arriving at Tsumagoi Village in Gunma Prefecture, the black lava landscape before you is a natural remnant of the great eruption of Mount Asama in 1783. The unique rock formations created after the lava flow cooled and solidified cover an area of ​​approximately 6.8 square kilometers and are listed as one of the three wonders of the world. Stepping into it feels like stepping onto another planet.
The park offers several walking routes. The most popular standard route starts from Somon, passes through the Omotesando and Asama-yama Kannon-do, and then returns along the Sato-sando, taking about 30 to 40 minutes. If you have more time, you can also choose the alpine plant observation route or the Okunoin shoal path, which takes about 40 to 60 minutes and allows you to observe pine trees over a hundred years old and moss communities along the way.
In spring, delicate alpine plants bloom among the rock crevices; summer offers a pleasant coolness; autumn brings a picturesque contrast between lava formations and red leaves; and winter transforms the area into a serene, snow-covered wonderland. Located at an altitude of approximately 1,300 meters, the park is accessible year-round, offering a completely different experience each time you visit.
These tickets can't be rescheduled or cancelled.
