Naked hijinks and eating eggs cooked in the onsen

I just got back from a day trip to Hakone, a popular onsen (hot spring) area, just outside Tokyo.

 The egg, cooked in a volcanic onsen, which turns the shell black and gives it a strange sulphuric smell. Yum.

Donning the yukata again:

Mount Fuji in the distance:

The faux-pirate ship I cruised the lake in. It was formed over 3000 years ago after a volcano exploded.

Solid advice:
