We journey from Gunma Pref., northwest of Tokyo, through Niigata Pref. and marvel at the colors of early summer. Glide along the Tone River through fresh verdure. Explore an art installation in a 750m tunnel and become part of the art in a mirrored shaft that reflects the gorge outside. Admire carvings by Japan's Michelangelo at a 500-year-old Buddhist temple. Try the local, pastel-colored sugar candies. Hover between blue sky and sea at a station on the Sea of Japan. Find your favorite color.
