Hakone Attractions: Owakudani - Volcanic Valley of Boiling Sulfur

"Owakudani" is an attraction that you must not miss when you come to Hakone. Owakudani is an ancient crater that constantly emits steam, sulfur smoke. The view is breathtaking. In addition to the wonders, you can also eat black jade on the life-enhancing hot spring. Black yuzu is made by soaking eggs in a natural hot spring pool at 80 degrees for 60 minutes, then steaming them for 15 minutes using natural geothermal heat at 100 degrees. Since the hot spring contains iron, the iron contained in the hot spring will attach to the eggshell during the egg cooking process, and the iron will become black iron sulfide after acting with hydrogen sulfide, so black jade will be like charcoal. However, it actually tastes not much different from ordinary eggs. #See the Earth in an instant #大wakugu #Hakone #黑玉子
