Mount Fuji's two-month climbing season officially opened Tuesday and about 250 climbers ascended to its summit to watch the sunrise.

The 3,776-meter mountain is the highest in Japan. It is considered a sacred symbol of Japan, and some 160,000 people climb to the shrine at its peak every summer.

The first climbers of the season did not get to see the sunrise at 4:30 a.m. because of thick fog, though the sun momentarily broke through about 20 minutes later.

It is open to climbers until Aug. 26.
