Overview

Mt. Tanigawa is an amazing mountain in northern Gunma which is easily accessible via train from Tokyo. The trailhead is located next to Doai Station, which happens to be the deepest underground train station in Japan. Doai Station is 70 meters underground, with 486 steps leading all the way from the platform up to the surface. It takes about 10 minutes and there is no escalator or elevator, so many say the start of your hike begins here.

Mt. Tanigawa is also served by a large ropeway, taking you up to 1300 meters, making day trips possible. The ropeway doesn't take away from the excitement though, as the trail that reaches the peak contains a variety of steep terrain features, with chains and ladders to assist with the ascent. It's also stunningly beautiful with a combination of boardwalks, massive boulders, and vast landscapes of bamboo grass, resembling waves rolling along a vibrant green ocean. Skipping the ropeway also provides an enjoyable hike through the forest and onto a neighbouring ridgeline with its own set of via ferrata, gorgeous views, and diverse terrain.

Mt. Tanigawa used to be known as the "mountain of death" due to the high number of failed rock climbing ascents. Over the past 90 years, more than 800 people have died while climbing Tanigawa. Although, only a tiny fraction of these were hiking trips and nowadays it's safely hiked by people of all ages. It's also part of the Hyakumeizan.

The most common trail options include:
- The Ropeway Trail: an out-and-back hike from the top of the ropeway.

- The Nishiguro Ridge Trail: a loop hike using the ropeway only for the descent.

- The Tanigawa Horseshoe Traverse: an overnight ridgeline loop covering a number of peaks.

We'll cover all 3 in this guide, with the main focus being the loop hike that climbs up the Nishiguro Ridge and then catching the ropeway back down.

Sleeping

There are a number of shelter huts located all over the Tanigawa mountain range, but most of them are pretty basic. There are 2 proper mountain huts, the Tanigawa Shoulder Hut located right next to the Tanigawa peak, and the Yomogi Hut located nearly halfway along the traverse. Another halfway option is the Shimizu Shelter Hut which has a small space for a couple of tents. For the overnight traverse, use the hiking map to plan how much time you want to dedicate to each day, and then check photos of the shelters on Google Maps to help you decide where to sleep.
