Ōwakudani
大涌谷
Owakudani, Hakone · 箱根
An active volcanic vent reached by ropeway, where sulphur vents steam continuously and eggs boiled in the springs come out with black shells.
Why it’s worth it
Eating one black egg is said to add seven years to your life. The ropeway closes without notice when gas levels rise — check before you plan around it.
