Yushin Valley | The Hidden “Blue River” Paradise in Kanagawa
Deep in the mountains of Kanagawa lies a breathtaking secret — Yushin Valley, a mystical gorge known for its mesmerizing “Yushin Blue” river.
Only accessible by foot through a series of tunnels, this secluded valley rewards visitors with one of Japan’s most stunning natural sights.
💎 The Magic of “Yushin Blue”
The water of the Yushin River glows with an unreal turquoise-blue color, created by fine minerals reflecting sunlight.
Surrounded by untouched forests, the color changes with the seasons — from emerald green in spring to deep sapphire in autumn.
When the morning mist rises and sunlight filters through, the entire valley seems to shimmer with a mysterious glow.
🚶♂️ A Journey Through Silence
Getting to Yushin Valley is part of the adventure.
You’ll walk along an old forest road and through a series of unlit tunnels — an experience that feels like stepping into another world.
The walk is about 2 hours one way, so good shoes, a flashlight, and water are essential.
But once you reach the iconic Yushin Blue Bridge, every step feels worth it.
🍂 A Hidden Gem for Nature Lovers
Far from city crowds, Yushin Valley is a peaceful retreat where you can feel the heartbeat of nature.
Whether you’re a hiker, photographer, or just someone searching for tranquility, this place will stay in your memory long after you leave.
