Oiseyama Daiyue is located in Kamakawa, near Asahikawa City, Hokkaido, Japan. It is the highest peak in Hokkaido, and it is more than 2,000 meters above sea level. It takes about an hour and a half to get to the Daiyue cable car station from JR Asahikawa Station. There is also a shuttle bus from Asahikawa Airport. Take a ten-minute box cable car to increase the height of 500 meters, and then come to the mountain position to see the station, so you can start hiking. However, late July to early September is the rainy season in Hokkaido. It often rains and the fog is very thick on the mountain. It is not a good season for hiking. Less than a few hundred meters from the position, the plank road is already a mess of stones, inconvenient to walk, rainy days are more dangerous. The ice layer on the surface of the two small ponds on the mountain has not yet completely melted, and it is vaguely visible in rain and thick fog, and white light shines from time to time.
