One day in November, two years ago, I visited Korankei Valley in Aichi prefecture and enjoyed the gorgeous autumn foliage there. But the place was getting more and more crowded by the minute, so I 'evacuated' from Korankei and drove away for about an hour and half. When I dropped in at a restaurant, one of the staff there told me about this 'secret' Kamikoshi Valley. Only a few tourists go deep into the mountain to this place, or rather, most people don't know about it except for well-informed locals. When I stepped into this valley, I was at a loss for words. For a while I forgot even to breathe. The iridescent valley was THAT gorgeous.

When you see the faces of people looking up at these red leaves, you'll find their faces are also red, reflecting the color of the red leaves (Photo: Masayoshi Hirose)

You have to be very careful when you take photos of autumn foliage...sometimes the colors may mix together and you'll lose all the details (Photo: Masayoshi Hirose)

Red, blue, vermilion, yellow, green...these primary colors create a beautiful picture with high, strong contrast (Photo: Masayoshi Hirose)
