Daisetsu Kogen Onsen

With 2,019 m, Midori-dake is shorter than Asahi-dake, but the hike to the summit is longer (2-4 hours) since it starts from a lower altitude, the Daisetsu Kogen Onsen. It is a popular place to see alpine flowers during July-August and autumn colors during mid September. From the summit of Asahi-dake, you may hike another 2 hours to the top of Hakuun-dake..

Gindensai is an extremely popular spot for viewing autumn colours and other terrific views of the Daisetsuzan Mountains, via the hike to the 2,078-m-high Aka-dake, which takes about 3 hours, followed by an easy 30-minute hike to Koizumi-dake. From there, another 50 minutes hike takes you to Hakuun-dake.

The tallest mountain in Hokkaido (2,290 m) and one of its main attractions. The easiest way to reach Asahidake is by bus from the city of Asahikawa. Catch a bus from outside Asahikawa JR station, via Asahikawa Airport to the Asahidake Ropeway station. There are about 4 buses per day in each direction. The bus will take you to the beginning of a cable car ("ropeway", ¥2800 /3500 return depending on season). The top of the cable car leads to a plateau with a short scenic walk to a set of fumaroles, and a longer walk (1.5-3 hours each way) to the summit of Asahidake.

The most accessible of the Daisetsu Mountains (the ropeway is just inside Sounkyo) and the easiest hike as a combination of ropeway and chair lift will leave you at about 1-2 hours from the top. Not surprisingly, it's also a quite popular hike and can be quite crowded during peak seasons. If you are not interested in hiking to the top, there are also quite a few easy walking trails and observation platforms..
