Shikoku is Japan’s smallest main island, known for its peaceful vibe, temples, and natural beauty. It’s famous for the 88-temple pilgrimage route, which attracts spiritual travelers. You can explore hidden valleys, like Iya Valley, or cross stunning bridges like the Seto Ohashi. Matsuyama has Japan’s oldest hot spring, Dogo Onsen, and delicious local udon noodles are a must-try. Shikoku is perfect for a slower, more relaxing adventure away from the big city crowds.
