NIKKO, Tochigi Prefecture—The fall foliage is at its peak here in the Oku-Nikko district that encompasses a number of tourist attractions. 

Trees in vivid shades of red and yellow delighted visitors driving the Irohazaka mountain route that connects downtown areas with Lake Chuzenjiko.

At Hacchodejima, a small scenic peninsula jutting into Lake Chuzenjiko, maple and oak trees were also dyed in the rich colors of the season.

The autumn foliage was about two weeks late this year due to the unusually hot summer, but the Nikko City Tourism Association said the recent drop in temperatures caused a rapid shift in the landscape.

The association recommends that tourists visit the lower-altitude area around Nikko Toshogu shrine now that the autumn leaves in Oku-Nikko are nearing the end of their season.
