Eggs boiled in the sulfurous water of Owakudani
The sulfurous fields of Owakudani are not only impressive to watch, they also are famous for their black eggs called kurotamago (黒たまご). Normal eggs are cooked in the hot sulfurous water, which turns their shells black in a chemical reaction. The eggs are cooked in the higher and deeper sulfurous fields and transported to the public area through metal baskets on a rope. It is quite funny to see these basked full of black eggs flying through the air.
These black eggs are very popular as legend says that eating one egg will extend one’s life by seven years.
The eggs usually are sold on site only in sets of 5 with a little bit of salt and people eat the eggs on site at tables prepared for this purpose. Having black eggs as a snack surrounded by the sulfurous fields is quite an experience.
