Crack the Mystery of the Black Eggs

Food & Drink Mountains Hakone Hakone-Yugawara

This time, we join Grace and Ryosuke at Owakudani, a volcanic valley in Hakone. Owakudani, which literally translates to "great boiling valley," is known for its hot springs, but is also home to sulfur mines and vents. And one of the more interesting regional delicacies from the area are kuro tamago, or black sulfur eggs. The eggs, which are said to add seven years to your life just by eating one, are dipped into the volcano's sulfur-laden water, which turns the shells completely black. However, you actually might be surprised how it looks and tastes when it's finished.

To find out, watch the video above and be sure to let us know if you'd be willing to give one of these a try!
