Today was mainly a travel day. After returning to the hotel from Lake Mashu and having breakfast, we piled into the bus. Not long afterwards, we stopped for a while at Iozan (or Sulphur Mountain) which is between Lake Kussharo and Lake Mashu. Obviously, a thermal area and somewhat reminiscent of some I have visited in New Zealand.
This last image is from the carpark, looking I think towards Lake Mashu.
