The autumn foliage has reached its peak around Taisetsu Kogen Onsen in Sounkyo in the town of Kamikawa in northern Hokkaido. The red rowan and yellow butterfly maple (acer tschonoskii) leaves created beautiful patterns amid the sunlight during the fine weather on September 25.
Taisetsu Kogen Onsen is located in Daisetsuzan National Park, and many tourists could be seen walking on the hiking course around the marshes there. Those enjoying the scenery from the Kurodake Station of the Kurodake Ropeway were also conspicuous.
The temperature dropped to a low of 1.2 degrees at just after 3 a.m. in Kamikawa on September 25, but rose to 17.4 degrees during the day. This difference in temperature helps create the vivid colors on the mountain.
