Sulfur mountain in Hokkaido.
The name of "Sulfur Mountain" can be seen all over the world, needles to say. Even in Hokkaido, two of them are in the eastern part of Hokkaido.
One is in Shiretoko peninsula which was on the list of the world heritage of UNESCO. The other is near the lake Kussharo and many people visit this area from other part of this island and the globe.
This area was prohibited to enter because Japanese army owned and controled this area to produce gunpowder.
Now this are is one of the most popular part in Hokkaido to visit.
Everybody is on his/her own but some consideration should be shown, I think.
Am I wrong?
