Hiking the Nakasendo Trail: Usui Pass to Yokokawa Station & Megane Bridge, Gunma Prefecture

The Nakasendo Trail is a 530-kilometer ancient highway that connected Tokyo with Kyoto during Japan’s Edo period (1603-1868). This section of the trail, spanning from Usui Pass to Yokokawa Station and including the iconic Megane Bridge, offers an immersive hiking experience in Gunma Prefecture. With its diverse landscapes, rich history, and picturesque villages, this two-day hike is a must-do for nature enthusiasts and culture lovers alike.

Day 1: Hike to Yokokawa Onsen (15 km, 5-6 hours)

Begin at Usui Pass (1,216m), the highest point on the Nakasendo Trail in Gunma Prefecture. The initial ascent is steep but rewarding, with stunning views of the surrounding mountains and valleys unfolding as you climb higher. As you descend into the Kiso Valley, the trail flattens out, passing through tranquil forests and traditional villages. Take a break at one of the many resthouses or teahouses along the way to refuel and soak up the local atmosphere.

Accommodation & Dinner

Arrive in Yokokawa Onsen (hot spring) in the late afternoon and treat yourself to a well-deserved soak in the natural hot springs. This charming hot spring town is nestled deep in the mountains, offering a serene atmosphere and delicious local cuisine. For accommodation, choose from one of the many ryokans (traditional Japanese inns) or guesthouses in the area.

Day 2: YokOKAWA ONSEN TO YOKOKAWA STATION & MEGANE BRIDGE (12 km, 4-5 hours)

After a restful night’s sleep and a hearty breakfast, set off early from Yokokawa Onsen. The trail follows the Kiyoshi River, passing through dense forests and picturesque villages. Be on the lookout for local wildlife, including monkeys and deer, as you make your way downstream. As you approach Megane Bridge (Spectacles Bridge), the Nakasendo Trail’s most iconic landmark comes into view. This impressive stone arch bridge, built in 1843, is an engineering marvel and a photographer’s dream.

Return Journey

After taking in the sights and sounds of Megane Bridge, continue on to Yokokawa Station, where you can catch a train back to KaruizAWA or Tokyo.

Tips & Advice

  • AccomMODATION: Book your accommodation and hot spring reservations well in advance, especially during peak season (September to November).
  • FOOD & WATER: Pack light meals and snacks, as options are limited along the trail. Refill water bottles at resthouses or teahouses.
  • MAPS & NAVIGATION: Carry a detailed map of the Nakasendo Trail and a GPS device or smartphone with offline maps, as cell phone reception can be spotty.
