Haruna, combining 400-year-old Mizusawa udon, the nostalgic stone-step town of Ikaho Onsen, and the breathtaking scenery of Lake Haruna.

Course Highlights

  • Mizusawa Udon: One of Japan's three great udon. Enjoy firm, translucent noodles made only from wheat flour and salt at a long-established restaurant.
  • Ikaho Stone-Step Street: An atmospheric hot-spring main street of 365 stone steps, perfect for a stroll and street snacks.
  • Route 33 Winding Road: A flowing climb from Ikaho Onsen up to Lake Haruna, with a must-see panorama from Takane Observatory.
  • Lake Haruna & Mt. Haruna-Fuji: A caldera lake mirroring the graceful cone of Haruna-Fuji closes the ride in autumn colors.

Riding Tips

Route 33 features hairpin bends and tight curves. Autumn foliage is gorgeous, but watch for cold mornings and fallen leaves. On the return, hop onto the expressway early in the evening to avoid traffic.
