It looks like the end of the world - in fact it's only the end of Japan. This is Sakurajima volcano, on the southern tip of Kyushu, the most southerly of Japan's main islands. The nearby town does a nice tipple made from sweet potatoes. The photo makes it seem like a dangerous place, but when I visited, the only volcanic matter that landed on my head was ash. Still, serial volcano-chaser Martin Rietze was much closer in when he took this apocalyptic photo.
