The climb from Yari-gatake-sanso mountain hut to the peak of Mt. Yari-gatake is decidedly difficult, but there are strong and sturdy chains and ladders attached to the mountain along the way at key points to ensure safety. Every year, you see parents with their elementary school aged children climbing this area. However, saying that is not meant to be interpreted as a guarantee of your safety in any way.
You should refrain from attempting the summit on days or times when the weather is bad, when you don’t feel well, or when your desire to climb is not at 100%. If something should happen, it would be an enormous burden on other climbers, the staff at the mountain hut, and the mountain rescue team. Keep your alcohol intake the night before to a minimum as the damage to your body from drinking at a high altitude is much worse than at sea level.

Everyone wants to see the dawn from the summit the next morning, which is why there will be a traffic jam at the chains and ladders just before dawn. Try and adjust your departure to avoid the crowds.
Yari-gatake-sanso hut stands on the shoulder of the peak at an elevation of 3,080 meters. The summit is only another 100 meters higher, but both the ascent and descent are entirely covered in rocky terrain. It takes about an hour roundtrip to the summit and back to the hut. The ascending and descending routes are separated for the most part, so there are very few places you need to be careful about people passing in the opposite direction.

We will travel from the Yari-gatake-sanso mountain hut to the base of the spearhead summit. This is where the ascending and descending routes diverge. First, once you climb past the rocks, you will go around and climb while following the arrows. You will need to grab rocks, hold onto the chains, and climb ladders, so make sure you always have both hands available to use. Do not make the mistake of bringing trekking poles with you for the climb.

Once you clear the two long and short ladders that require the use of all five of your senses, you will reach a portion that is common to both ascenders and descenders, but for the most part, the places to ascend and descend are separated. Therefore, you should not have any trouble with people passing in the opposite direction. Up ahead are a series of two long ladders. You will get a sense of the high altitude, but the ladders are safe, so just go slowly. At the top of these ladders is the Mt. Yari-gatake summit and a 360-degree panoramic view. You can see all of the Northern Alps, the Southern Alps, the Yatsu-gatake mountains, Mt. Haku-san, and even Mt. Fuji. The only manmade object you will be able to see is the Yari-gatake-sanso hut at the summit shoulder.
