Best season

Horohoro-yama ホロホロ山 (1322m) is the twin of Tokushunbetsu-yama 徳舜瞥山 (1309m), connected via a high level ridge. It’s not the most popular of ski objectives as although the easiest access route starts from the high point on Prefectural Route 86, this only reopens in the final week of April. Moreover, it is difficult to recommend this route for the skiing given the gentle gradient and late spring conditions. It’s more of a nice spring walk on skis (or snowshoes) for those who like exploring. Having said that, the final narrow ridge is fun and the amazing summit views still make it a good day out in fine weather.

Location

Horohoro-yama lies southwest of Lake Shikotsu and inland from the town of Shiraoi on the Pacific coast halfway between the cities of Muroran and Tomakomai, a little under a two-hour drive from Sapporo. This route starts from the Horohoro-yama Pass parking area, here.

Route details

There are no official route markers. Ascend the slope behind the car park (elevation 620m) for a short distance then turn south on a gentle slope. At about 700m there is a steep drop to the skier’s left (east), and at 800m a short steep step, the only steep section on the whole route. From here continue up the broad gentle slope through widely spaced trees to a small peak at 1210m. Follow the ridge round to where it narrows at about 1300m. Leave your skis here for the final few hundred meters walk along the airy ridge to the summit. The return route is the same as the ascent.

Aspect
The main aspect skiers are exposed to on the descent and/or ascent is North. Therefore, keep an eye on the weather forecast a few days ahead of your trip to monitor wind, snow, and temperature. Also, since this route is in the general vicinity of the Shiribeshi area, consider looking at the Japan Avalanche Network weekly avalanche bulletins or the daily Niseko Avalanche Information website. These may give extra insight into avalanche conditions in the greater area around the route.

Snow and
route safety

Most of the route is on a broad ridge with few features and without good navigation skills it would be easy to become disorientated in bad visibility. The final ridge is narrow with a steep drop to the east and could be awkward in difficult snow conditions. On the descent be sure to check your position to avoid straying off route. Below the steep step trend slightly right to avoid overshooting the car park but mind the steep drop to the east.

Route Trip Notes

Route blurb from the Hokkaido Yukiyama Guide (2015), p. 210 (translated by Hokkaido Wilds)

During winter Prefectural Route 86 connecting Shiraoi Town with Otaki District of Date City is closed. In a normal year the gate is opened around the 25th of April, and the snow climbing season lasts for around two weeks after that. From Horohoro Pass there are no steep slopes except for one place. By skis or on foot, you can stand on the summit in about three and a half hours. The mountain is superbly situated, with views behind you to Lake Shikotsu and from the summit west to Lake Toya. And happily it’s easy to climb since given the season there is no need to break trail.

It was May Day, and the snow was getting decidedly thin in the hills around Sapporo. There wasn’t much at the car park by the tunnel either, and we did briefly wonder if we were wasting our time. But it was a beautiful sunny day and after linking patches of snow through the sasa dwarf bamboo we came out onto the broad ridge, which still had plenty of snow cover. From here it was a very pleasant skin up through trees and on to more open terrain with beautiful views all around.

We left our skis at the start of the final narrow ridge. Jeff strode off confidently along the first few meters then promptly fell into a waist deep hole between the haimatsu dwarf pines. After he clambered out awkwardly we continued on, watching our footing a bit more carefully now. The snow was soft and there was no cornice, so no danger of slipping off the ridge itself. Soon we were enjoying the panorama from the summit – Lake Toya in one direction and Lake Shikotsu the other, with Yoteizan standing proudly to the northwest. Closer still the white pyramid of Tokushunbetsu-yama stood sentinel at the end of the connecting ridge, and we could make out three snowshoers on the saddle below.

Skiing down, however, was a definite anticlimax. The snow was soft, slushy and slow. With little gradient to aid progress it was even difficult to get turns in most of the way down. Near the bottom the sasa joined in the fun by grabbing at our skis and tipping us over. The final stretch to the car park involved a couple of hundred meters of fighting our way through tangled thickets of the dreaded stuff. Nevertheless, enjoying our post-exertion soak in the steaming outside bath at Horohoroso onsen, we agreed that despite the rubbish skiing it had definitely been worth it for the high country atmosphere and wonderful views.
