日光、いろは坂の紅葉がみごろです。
We're seeing peek autumn leaves at Irohazaka in Nikkou.
日光を見ずして結構と言うなかれ・・・
Don't use the word ‘marvelous' until you've seen Nikko.
Until you've seen Nikko, you haven't seen anything.
Your travel in Japan would not be complete without a visit to Nikkou.
Nikkou is not only culturally and historically significant but also is famous for its autumn-leaves-viewing spots.
