TOPO
Daisetsuzan's Higashidake 大雪山系東岳 (2067m) is one of the more easily attained 2000m+ peaks on the eastern side of the Daisetsuzan National Park in central Hokkaido. The long approach is amply rewarded with access to a smorgasbord of freeride terrain on the peak's broad and varied eastern face. Exposure to technical terrain can be easily dialed up and down depending on skiers' appetites. The summit affords expansive views across the vast alpine Daisetsuzan plateau that makes up Kamui-mintara, the playground of the gods.

Location

Higashi-dake sits at the northeast corner of the Daisetsuzan Range in central Hokkaido, surrounded by more familiar peaks and locations such as Hakuun-dake 白雲岳 (2230m), Aka-dake 赤岳 (2078m), and Ginsendai 銀泉台 (1517m). This winter approach to Higashi-dake starts at the Taisetsu Plaza 273 大雪プラザ273 on National Highway 273 that cuts across the northern reaches of the Daisetsuzan Range from Obihiro to Sounkyo/Kamikawa.

General notes

There’s no summer trail to the summit of Higashi-dake. As such, it’s a winter objective only for the hardiest of ski tourers, seeking a long day of walking and climbing. This route to the peak, approaching from the east, gives excellent access to Higashi-dake’s broad east-facing slopes, offering a multitude of steep ski lines of varying difficulty and complexity. The peak will only add fuel to the fire of desire to explore more of the Roof of Hokkaido.

  • Mountain name: The reason we put Daisetsuzan in front of Higashi-dake is because there’s another tall Higashi-dake in Hokkaido. The other one is in far eastern Hokkaido, on the Shiretoko Peninsula. That one is called Shiretoko Higashi-dake 知床東岳 (1520m, location).
  • Mechanized approach: The 16km-return forestry road walking might prompt visions of using a snowmobile to make the approach more palatable. Recreational use of snowmobiles in this area of the Daisetsuzan National Park, even on forestry roads, is not permitted (as per signs posted at the entrance of the Ginsendai access road).

Route details

From the large car parking area at Taisetsu Plaza 273, walk about 200m south along the main highway to the entrance to Route 1162, the narrow road leading west up to the turn-off to Ginsendai 銀泉台. The turn-off to Ginsendai is about 1.6km. From the turn off, keep heading straight west along the Horokaishikari-gawa River ホロカイシカリ川. The forestry road continues another 4km or so to altitude 1180m. Once the forestry road ends, it’s still an easy skin alongside the river to where multiple streams converge, at around 1300m.

From this point, there are several uphill options available. Keep heading straight west for a steep approach to the summit ridge, often requiring boot crampons for the final approach. Head northwest up towards Oku-no-daira 奥の平 for a more circuitous but much more mellow approach that will unlikely need crampons.

For the descent, either take the conservative approach by skiing the circuitous descent via Oku-no-daira, or ski any of the steeper lines you scoped out from below as you ascended. The descent out on the forestry road is just enough of a decline that it’s unlikely skiers will need to don skins again. Some minor poling will ensure a quick exit via your skin track.

Route Timing
Up | 6.5hrs
Down | 2.5hrs

In firm spring conditions, it’s unlikely that fit parties will get much change out of 10 hours return on this trip. In deep winter, with deeper snow conditions, this will be a very committing trip that could feasibly take up to 12 hours return. In reality, skiers may find that camping at the base of the eastern face will open up time for more exploration options.

Transport

Public transport:

There is no public transport to this route. The closest that public transport will get you is the mountain village of Sounkyo 層雲峡, to the bus stop just outside the Sounkyo Post Office (here). From there, it would be a 15-minute taxi ride to the trailhead. The only taxi company in Sounkyo is Sounkyo Kanko Hire 層雲峡観光ハイヤー (website | location | TEL: 01658-5-3221). We’d recommend calling (in Japanese) in advance of your visit to let them know you’re coming.

By car:

Taisetsu Plaza 273 is a 3hr drive from Sapporo on the Doo Expressway via Asahikawa and Sounkyo. There is ample parking at the Taisetsu Plaza 273, as well as public toilets. Note that there’s very little in the way of services once you leave Sounkyo village.

Aspect
The main aspect skiers are exposed to on the descent and/or ascent is East. Other aspects that may also be encountered while following the route outlined on this page include: South, North, West. 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 Furano area, consider looking at the Furano Avalanche Center (on Facebook). They issue sporadic observations throughout the season which may give extra insight into avalanche conditions.

Snow and
route safety

The Daisetsuzan Range is a big, remote place. This remote northeast corner of the range is particularly so. Skiers should have a high level of self-reliance. Temperatures in this area of Hokkaido can be extremely cold – be prepared. Any peak over 2000m in Hokkaido is serious alpine terrain. Take wind and visibility forecasts seriously, and make conservative decisions.

On your way back through Sounkyo, we highly recommend having a soak at Kurodake-no-yu 黒岳の湯 (location, 600yen). There’s a relatively good view towards the mountains from the 2nd floor open air bath. They have a sauna and cold plunge pool, and large relaxation area with massage chairs. On the 1st floor is the Bear Grill Canyon restaurant, serving pasta and other European-style meals.

Route Trip Notes

For Sapporo dwellers, a far-away peak like Higashi-dake in the Daisetsuzan Range requires commitment. Not just because it’s a long day out. A long day out just means an early start. But factoring in the drive there and back from Sapporo, it adds up to a very full weekend.

As it happened, Rick was staying in Obihiro, so on the Saturday we drove to Taisetsu Plaza 273 via Obihiro. We got away just after lunch, so it made for perfect timing to visit a supermarket, pick up Rick, eat some dinner, have an onsen soak, and park up at the Taisetsu Plaza 273 for the night.

Rick pitched a tent on the snow, Timbah slept under the stars, and Haidee and I bunked down in the van. It was a quiet night with only a couple of vehicles passing all night.

The morning broke still, clear, and cold. My guess was it was around -15 degrees C.

We all bundled into the van, the diesel heater ticking over, for a warm breakfast before venturing out for the day.

By the time we got all our gear sorted out, we were all feeling the cold in our extremities. Frozen hands, chilled feet.

We made the first 200m down the road on foot. The day was just breaking. Colors and moods subduded.

At the entrance to the road along Horokaishikari-gawa River, we donned skis and started the 8km approach to Higashi-dake’s eastern face. We all moved fast, keen to warm our cold bodies up. It’s not often that I wear my mid-weight insulated jacket while skinning. Today, I didn’t end up removing it until the sun started peeking through the trees, a full hour and a half after we set off.

The forestry road approach promised to be long, but true to the guidebook‘s words, it was a very pleasant walk. Well within the Daisetsuzan National Park, the forest was old, silent, and majestic.

We were setting a cracking pace, so soon found the end of the forestry road.

We were now picking our way along the Horokaishikari-gawa River. Here and there, the bullet-proof southern-aspect snow made things a bit treacherous.

We hoped that as the day wore on, the snow surface would soften up a little for the descent.

It took us a leisurely 3hr 45m to cover the nearly 9km of gently ascending approach before we arrived at the base of the climb proper. The moderately narrow valley we’d be travelling westwards along suddenly opened up.

We were in full sunshine, and the day felt good.

We stopped for a quick lunch before pushing on.

It was around this time that the long approach appeared to be taking its toll on the team. We had a powwow. We weren’t aware at this point whether we’d be able to ski all the way back down the forestry road, or whether we’d need to don skins again. We knew that we still had a lot of climbing to go to get to the summit. Perhaps most importantly, however, we knew that we were racing against the clock. Windy.com had forecast 60km/h+ gusts from noon, and it was already 10:30am. 

Some of the team was keen to press on to the summit, but we made a compromise to get to Oku-no-daira at the top of the saddle we could see from below. From there we’d have good views across the Daisetsuzan alpine plateau, and would be able to make a better decision on whether a summit attempt was feasible or not.

As we ascended, the views only got better, wider, and more expansive.

We were in a seldom-visited area of Daisetsuzan National Park. Indeed, winter is the only time this zone is accessible – there are no hiking trails here.

This mellow approach to the plateau via the southeast valley was a walk in the park. We hardly needed to kick-turn, and we arrived at Oku-no-daira with our skis and skins on.

A frigid, stiff wind was blowing at the top. It was clear that the summit would have to wait for another day. We had run out of time, and already strong gusts of wind were whipping snow and ice up into wind funnels.

We ripped skins and started gingerly skiing the descent on hard windpack, breakable in places, then turning to breakable crust, and then to more manageable warm snow.

Everywhere we looked, we saw beautiful potential in the multitude of lines beckoning us on the eastern face for another day and another attempt.

Mercifully, the forestry road exit was surprisingly good. Had it been any flatter it would have been hard going. As it was, however, it was just the right declination to just require a bit of poling here and there. Freshly-waxed skis were the key here, however. Rick’s were not freshly waxed, and he was poling much more than the rest of us. 

Just as we arrived back at the Taisetsu Plaza 273, a large bus of Taiwanese tourists showed up. One inquisitive chap walked over to us as we were packing away our gear, clearly interested in the spectacle. 

We were away from the parking lot by 1pm, in the onsen by 2pm, having sushi dinner at 4:30pm, and back in Sapporo by 7pm. 

We didn’t hit the main objective for the trip, but the secondary objective (having a long walk and climb in Daisetsuzan’s wilderness) was well and truly achieved.
