Aim for the Tanigawa Blue! March is the time to challenge Mt. Tanigawa, a world-class value in Gunma Prefecture! Tenjin Ridge Details!


If you want to see the Tanigawa blue and white snow-capped peaks, March is the best month to climb. In March, you can enjoy the white ridge line, deep snow cliffs, clean air, and the great nature of Mt.Tanigawa-. Please enjoy the world-class Mt. Tanigawa to the fullest.

Tanigawa-dake in March Overview

The winter pressure pattern of high in the west and low in the east continues from December to February, but in March, the pressure pattern changes to one where low and high pressure pass through alternately, and “sunny” and “rainy/snowy” weather alternates every two to three days. In late March, the temperature rises and the snow calms down, making it easier to walk with crampons and ice axes.

For beginners, the weather will determine whether you can climb Tanigawadake or not. Tanigawadake, which is located on the divide between the Pacific Ocean and the Sea of Japan, has a very changeable climate.

On rough days, it is a mountain with really severe weather. Even when the weather is clear, be aware that strong winds often blow on the ridge line. Tanigawa-dake is a beautiful and nice view because of its harsh natural environment.

Weather map for sunny days in March

The weather map on the right is for March 11, 2021. High pressure will cover Japan and it is truly a perfect day for climbing. In March, the probability of such a day with a mobile high-pressure system is increasing.

How many sunny days are there in March?

Here is a side-by-side weather map for the month of March 2021. The number of days with high pressure is about 12 (days marked with ★), proving that high pressure and low pressure will alternate every 2 to 3 days. If you plan about four candidate days in the middle to the end of the month, you can get the sunny days.

Tenjin Ridge route details!

The most popular route is to use the Tanigawadake ropeway and climb Tenjin One. By riding the ropeway, it is possible to climb the mountain for one day. Here are some points of Tenjin One.

Where is the steepest route on Tenjin Ridge?

These are the three places.

The first ascent from Tenjindaira to Tajiri One (Map 1)
This is the first climb from Tenjindaira Station up the side of the ski resort. It is an advanced course of the ski resort and has a certain degree of slope, and since it is the first step in the morning, it is quite a tough climb.

Climbing to Tengu no Tamari-jo (Map ③)
A steep climb continues from the Kumanazawa refuge hut to Tengu no Tomariba. It is a tough part in the middle, but the forest limit is exceeded and the view opens up quickly. Enjoying the view of the chopping board on the left and Hitsugousawa may help you forget your fatigue.

Ascending to the Hut (Map 4)
The final climb up to the shoulder hut is a key point of effort. The steep climb continues, and it is difficult to see what lies ahead, but let’s not be hasty and climb steadily, step by step. Soon the signpost for Mt. Tanigawa and the shoulder hut will come into view.

Are there any dangerous points on Tenjin Ridge?

The only place where there is a danger of slipping and falling is before the head of Kumanasawa (Map 2), which is marked 1441 on the map, where you descend the slope and traverse (cross) the slope. If there is enough snow and the foothold is firm, you can pass through without any problem, but if there is little snow, the exposed rocks make it a very thrilling narrow path. It is the most dangerous point of Tenjin Ridge. Concentrate and proceed carefully to avoid catching your crampons.

Points to keep in mind when descending a mountain

Even if the weather is clear, clouds can easily appear in the afternoon. Also, be careful not to follow backcountry trails, as they will lead you into Nishikurosawa. When descending Tenjin Ridge, there are three points where it is easy to make a mistake.

The descent from the shoulder square (Map ⑤)
The descent from Tengu no Tamaraba (Map 6)
The descent toward Kumanasawa refuge hut (Map ⑦)

Is there a risk of avalanche?

When the winter pressure pattern is high in the west and low in the east, Tanigawadake is exposed to heavy snowfall, which increases the risk of surface avalanches. In March, the temperature rises and the snow clears up, making it less dangerous than in the severe winter season, but you should be careful the day after a snowfall.

Aim for an Instagram photo at Tanigawadake!

Here are three recommended spots for cool photos.

(1) The main ridge line extending west from Tanigawa-dake

The best shot is on the way up to Toma-no-Mimi from the shoulder hut. The white ridge line leading to Mt. Naeba, Mt. Asama, and Mt.Fuji.

(2) Toma’s ear to Oki’s ear, Oki’s ear to Toma’s ear

This is a photo taken from Toma-no-mimi to Oki-no-mimi with Oki-no-mimi in the background. The huge snow cliffs unique to Mt. Tanigawa and the traces of boarders who risked their lives to ski down Machigasawa are magnificent.

(3) On the way up to the Tengu no Harijo (pool of the Tengu), we started to see the Manaitagura (俎嵓).

As we climbed up Tenjin Ridge, we could see the dazzling white ridge and the cliff of chokepoint on the left side.
