TOPO
Kaun Bowl 華雲ボウル is a vast alpine cirque-like bowl high up in the alpine zone of the Tokachi Range 十勝連峰. Sitting to the north of the ridge connecting Furano-dake 富良野岳 (1912m) and Sanpo-zan 三峰山 (1866m), there are plenty of terrain options, ranging from relatively mellow to pucker-up steep. Given the right conditions, the snow can be some of the best in Hokkaido - deep, dry, and cold. Expect vast views west across the Furano Plains, and enjoy an après-ski onsen soak looking directly at the face you just skied.

Location

Kaun Bowl 華雲ボウル is a large bowl-like topographical feature – almost like a cirque – directly below Sanpo-zan 三峰山 (1866m) and Furano-dake 富良野岳 (1912m) in the Tokachi Range in central Hokkaido. The most common approach is from the Tokachidake Onsen carpark, starting with a heinously steep bootpack just to the looker’s left (east) of Ryounkaku Onsen 凌雲閣温泉.

General notes

Once you’re there, this is a smorgasbord of deep powder lapping potential, high up in the alpine of the Tokachi Range. On a clear day, views down the range and across the Furano Plains are stellar.

A common theme in this route guide, however, will be how heinous the entry can be to this otherwise relatively straightforward backcountry route. It’s a steep, no-fall bootpack down the concrete-like debris of where Ryounkaku Onsen dumps their plowed snow. It’s not that you’ll need boot crampons, but in certain conditions, an ice-axe may provide peace of mind.

Route details

From the large Tokachidake Onsen parking lot, strap your skis to your backpack for the short bootpack down to the stream, just looker’s left of Ryounkaku Onsen. Expert skiers in the right conditions might feel comfortable jump-turning their way down. Either way, however, you’ll be putting skins on after crossing the Nukkakushi-furano-kawa Creek ヌッカクシ富良野川 to start the climb up to Kaun Bowl. By mid-January, you should have several options for snow bridges across the creek.

Once across the Nukkakushi-furano-kawa Creek, wrap your way around the base (northern terminus) of the spur right in front of you, climbing slightly as you go. Don’t climb too much, however, as this will just lead to having to drop altitude again to cross the Sanpozan-sawa Creek 三峰山沢 gully.

Once you’ve navigated the two creeks, it’s plain sailing up the narrow ridge just east of Kokonoe-no-taki 九重ノ滝 and Kaun-no-taki 華雲ノ滝 waterfalls, all the way to the small plateau at 1700m at the base of the final climb to the Furnao-dake summit. Anywhere above 1600m or so is likely to be rime and hard-pack though, so unless you’re dead-set on tagging peaks, this is where you rip skins and enjoy the protected powder of Kaun Bowl. Start early enough in the day, and you’ll enjoy at least three laps.

After getting your fill of Hokkaido’s highest-altitude powder, return to the Tokachidake Onsen parking lot the way you came. If you’re really lucky (and smart), you’ll be able to traverse around the contour lines such that you don’t need to don skins again.

The final sting in the tail of all that powder lapping you just did is the final boot pack back up the snowplow debris.

Route Timing
Up | 2.5hrs
Down | 1hrs

If you’re just doing a quick up-and-back, this route is unlikely to take most fit and experienced parties more than 3-4hrs. With a good forecast and good snow, however, it’s best to allow six hours to really squeeze every bit of lapping out that you can. Either way, best to start early, as the Tokachidake Onsen carpark fills up quickly, particularly on weekends.

Transport

Public transport:

The trailhead is accessible by public bus from Kamifurano JR train station – get off at the Ryounkaku Bus Stop 凌雲閣バス停. The trip will take about 40 minutes from the train station. The bus is run by the Kamifurano Town council. Timetable information is here: http://www.town.kamifurano.hokkaido.jp/index.php?id=1522. As of January 2025, the earliest bus bound for Ryounkaku Onsen was at 8:52am (arriving at Ryounkaku Onsen at 9:37am). There are only three buses per day heading up to the onsen (last one at 4:31pm). From Ryounkaku Onsen, as of January 2025, there were buses heading back down to the train station at 9:47, 13:37, and 17:27. Note that the bus goes via Hakuginso Lodge.

By car:

The trailhead is easily accessible by vehicle – it’s at the large snowplowed public parking area adjacent to the Ryounkaku onsen at the very top of the Tokachidake Onsen area. There’s room to park at least 30 cars in this car park, but particularly on weekends, the car park can fill up by 9am.

Aspect
The main aspect skiers are exposed to on the descent and/or ascent is North. Other aspects that may also be encountered while following the route outlined on this page include: South. 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

This entire route is above the treeline. While ‘only’ maxing out at 1700m, the Tokachi Range is well known for temperatures dropping below -20℃. Add in windchill, and this can easily drop below -30℃. Make sure you have the insulation layers needed for these temperatures. It’s easy to get lost beyond the treeline here too. Avoid this route in low visibility conditions. Also note that you’ll be travelling through relatively complex avalanche terrain. Indeed, the better slopes for skiing here are all classic avalanche terrain. Take your time, dig a pit, understand the snowpack before carving some tracks.

Onsen nearby

The natural choice for a post-ski onsen hotspring soak is Ryounkaku Onsen 凌雲閣温泉 (location, 800yen) next to the car park. The outdoor baths look east, out over the valley you’ve just skied. Just down the road is Kamihoroso カミホロ荘 (location, 6ooyen), with wood-lined outdoor baths that look west across the Furano plains. Slightly further afield is the wildly popular Hakuginso Lodge 白銀荘 (location, 700yen), with the largest outdoor bath facility in the area. If you’d prefer a wilder experience, there’s the Fukiage Onsen 吹上温泉 (location, free) – free wild onsen in the woods, accessed via a short 3 minute walk from the carpark.

Route Trip Notes

Nigel was in town, so along with Chris, a whole gang of us dragged him up to Tokachidake Onsen to explore the Onsen Slope and Kaun Bowl above the onsen.

Our party was a veritable gaggle of skiers, all looking forward to the famed high-altitude powder of the valley above Tokachi-dake Onsen.

It was the first time for any of us to bootpack the entry from just next to Ryounkaku Onsen. It lived up to its fame as an altogether head-scratcher of a start to a ski tour.

With hearts in throats, we all made it down unscathed.

The original plan for the day was to ski both Onsen Slope and Kaun Bowl. Something like this. To our dismay, however, all south- and west-facing slopes were baked. Grabby, hard-to-ski crust on top of soft snow.

Views were great, but we decided early on to bail on getting any higher on Onsen Slope, and made a beeline for the northern-aspect slopes of Kaun Bowl. 

By this time, we’d already climbed quite high along Onsen Slope, and were being treated to fantastic views of the Hokoiwa Chutes on Furano-dake.

Bailing on the Onsen Slope meant we had to find a spot to drop down to the west, down into the Sanpozan-sawa gully. From there we would gain the ridge that would take us up to Kaun Bowl.

The western-aspect drop down to Sanpozan-sawa gully was predictably heinous. Breakable crust on steep, soft snow. I’ve skied worse crust before though, so I had that consolation.

Once we were on the northern-aspects of Kaun Bowl’s looker’s right ridge, things were plain sailing. No more crust. Just pure powder to look forward to on the descent. The entire bowl called out to us as we ascended.

We climbed to around 1600m before the powder started to turn to dust-on-crust. Timbah and Tim pushed on up to the 1700m plateau, but it didn’t really do them any favours in terms of good-snow skiing. 

From 1600m to around 1300m, we enjoyed some great dry powder skiing.

Our original foray up Onsen Slope had burned through our daylight hours, so we decided to call it a day after just one run. In the Sanpozan-sawa Gully, we split the group into two. One half would ski down to the Furano-dake trailhead, and the other half would climb back up to the Tokachi-dake Onsen carpark and bring the cars down to us.

In hindsight, it probably would have been just as quick for all of us to don skins again and skin over to the Tokachidake Onsen carpark, and brave the bootpack back up. But I was keen to see the Sanpozan-sawa Creek exit, so hats off to the car shuttle boys for climbing back out to get the cars.

The Sanpozan-sawa Creek exit was tolerable. A little more flat than I had expected. But plenty of snow, and not too much side-stepping required. A bit of a drag on a snowboard (sorry Nigel), but all things considered, not terrible.
