The last thing we would have expected to learn about food in Japan is an unusual way of cooking sweet potatoes. But the inhabitants of the tiny village on the shore of lake Unagi are not only effectively living in a volcano, but also put the volcanic gases rising to the surface in their back gardens to good use: they use them to steam-cook vegetables.
Very few foreigners venture to the volcanically active Satsuma Peninsula at the southern tip of Japan (pictured above is Mt. Kaimon). Had the weather been more suitable for viewing the spectacular eruptions of nearby Sakurajima volcano, which was the main focus for our small group of volcano photographers this past January, we would never have discovered the strange treasures of the Unagi crater.
Whilst driving around looking for volcanological features, we ventured across a small country road which fortuitously took us right into Unagi crater over a low point in its rim. We continued to the tiny village of Unagi, which consists of about 50 houses tucked in the northeast corner of the crater by the edge of the lake. As we drove, we noticed plumes of steam rising from various points along the road and even out of the small gardens and yards behind houses.
The Japanese adore geothermally heated Spas; there's one even in this tiny hamlet. But the idea of building a whole village in a fumarole field seemed at best odd, and the simple concrete structures which had been built around many of the steaming vents were even more puzzling.
I poked my head over a wall to get a closer look at the source of one of the plumes, and was startled to find two Japanese women fussing over a package laid on top of the vent.
