The best way to explore gorgeous natural landscapes is with your own two feet. Slip on your hiking boots, hit Joyama and take the time to soak up the scenery.
When you've finished up at this trekking route in Izunokuni, why not check out Izu-Mito Sea Paradise, Shuzenji Temple, and Awashima Marine Park? They're near Joyama and also popular with many travelers.
