Owakudani is an active volcanic valley formed approximately 3,000 years ago when Mount Kamiyama erupted. Sulfurous steam vents rise from cracks in the ground, creating a dramatic, otherworldly landscape. The area is famous for its black eggs boiled in the sulfur springs - each egg is said to add seven years to your life!
Clear mornings for best Fuji views. Avoid after rain when volcanic gases are stronger. Check official site before visiting - area may close due to volcanic activity or gas levels.

When the egg is boiled in the sulfur springs, iron sulfide in the water reacts with the calcium shell to form iron sulfide, turning it black. The inside remains completely normal and safe to eat!
