About

Try the black eggs (黒玉子 kuro-tamago) at Owakudani. Boiled on site, their shells are a mottled black due to a chemical reaction with the sulphurous water, but the inside is quite tasty. According to Japanese legend, every one you eat will add seven years to your life. 5 eggs (and hence 35 years) will set you back just ¥500.
