On the Mt. Aka course, some slight coloring can be seen in leaves of the Sorbus matsumurana in the lower area of Daiichi Kaen. Although limited to certain areas, the coloring can be discerned even from a distance. This area is subjected to cold winds that blow down during the night, and therefore each year the leaves tend to begin changing earlier here than in other areas.
Although the leaves of the Arctous alpinus var. japonicus and Aconogonon ajanense are changing color, those of the Sorbus matsumurana and other trees are not changing anywhere along the entire course. Accordingly, it may be too early to declare the arrival of the fall foliage season.
Nevertheless, signs that fall is arriving are certainly evident in the mountains. The winds have become much chillier than they were a few days ago, particularly at the peak. And the number of days having a low temperature below 10 °C at the Mt. Hakuun hut has increased.
Although we are still only just past the midway point of August, the mountains are undeniably taking on a fall-like appearance. Visitors planning to venture into the mountains should prepare for the cold by bringing gloves, hats, and other such clothing.
*The only snowy gorge on the Mt. Aka course trail is a roughly 20-meter area that remains at Daini Kaen.
