Best season

Mt. Kokimobetsu-dake (小喜茂別岳 - 970m) is the little-sibling of the higher Mt. Kimobetsu-dake (喜茂別岳 - 1,177m) further to the north (Mt. Kimobetsu-dake route guide here). Access to Mt. Kokimobetsu-dake is just as easy though, and its mellow slopes are great for those just getting their feet wet in backcountry skiing. Expect a beginner to intermediate slope at the upper end of the route that is perfect for lapping a couple of times before heading down.

Route Map

Need to know details

Location

This Mt. Kokimobetsu-dake route is on the western side (Kimobetsu Town side) of Nakayama Pass, and is accessed from a carpark (here) about 500m down the road from the trailhead (here).

General notes

This route is marked as “perfect for beginner backcountry skiers” in the HokkaidoYuki-yama Guide (ISBN: 978-4894538047). This is a fair description; it is a relatively short approach (2 to 3 hours), the downhill slopes are not too steep, and it includes the satisfaction of bagging a peak. More experienced skiers might find the route underwhelming, however, and if time permits, pushing deeper into the backcountry towards the higher-altitude Mt. Kimobetsu gives access to much more enjoyable terrain for the experienced skier (see route guide here).

None
Route details

When we were there in January 2018, there were sporadic strands of pink taped attached to trees along the route. It is best to assume, however, that you will be navigating on your own.

Route Timing
Up | 2.5hrs
Down | 1hrs

About 2 to 3 hours from trailhead to summit, and another 1 to 1.5 hours back down to the trailhead. The upper slopes directly below the summit are good for a few laps though, so try to budget in enough time to enjoy those.

Transport

Public transport:

This route is not accessible by public transport.

By car:

There is a car parking area (here) about 800m down the road from the trailhead. As of January 2018, this parking area was home to some pre-fab construction buildings. As a courtesy, please ask for permission to park in their carpark – they should be very accommodating.

Aspect
The main aspect skiers are exposed to on the descent and/or ascent is Southwest. 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 avalanche bulletins (updated Tuesdays, Thursdays, Saturdays at 8am) 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

The main risk noted in the Hokkaido Yukiyama Guide is the ease of skiing down the wrong ridges and/or gullies on the way down. Check your location after each run to make sure you haven’t strayed too far off course.

On the way to Sapporo City, you’ll be passing through Jozankei Onsen area. A favourite of ours is the down-to-earth Matsu-no-yu Onsen on the Sapporo City side of Jozankei Onsen. If you’d like to pair onsen with lunch or dinner, try Kogane-yu Onsen next door; they have a very reasonable restaurant attached. If you have time, you might want to check out the Ainu Culture Center (location) just across the road from the onsen.

Route blurb from the Hokkaido Yukiyama Guide (2015), p. 170 (translated by Hokkaido Wilds)

Descending down the Nakayama Pass towards Kimobetsu Town, the triangular mountain visible on the right is Mt. Kokimobetsu-dake. It doesn’t have a hiking trail, so can only be climbed in the winter. From Nakayama Pass it looks like it is thick with trees, but on the other side of the mountain are long slopes with very little trees. This makes it a simple mountain to climb. People even climb it in simple snowshoes, but it is home to long gentle slopes and perfect for beginner backcountry skiers, new to the winter mountains.

 

After pulling the plug on climbing up Mt. Kokimobetsu last week due to high wind and snow (and then opting to ski Mt. Onuma instead), a forecast for sunny skies this weekend motivated us to head back this weekend to try out our luck again.

When we arrived at the carpark about 400m down the road from the trailhead, things were looking sunny. With three of us with skis and one with a snowboard, we made the initial trudge along the roadside. As usual, actually getting off the road and onto the snow required some scrambling…

The blue skies lasted about 20 minutes once on the trail, before clouding over completely. From the trailhead, the route climbs almost immediately up to the closest pylon, before carrying on on a 51degree bearing straight towards the peak.

The route continues on the 51degree bearing through thin stands of trees and sporadic clearings. For the most part the middle section of the route is a very gentle uphill gradient and in parts it is flat.

At around 730m in altitude, the route finally starts climbing in earnest towards the peak. In the end, this will give about 240m of easy, fun skiing on the downhill given the right conditions.

We noticed someone had set up a basic tarp shelter at the base of the hill – we would later see two snowboarders huddled in the shelter cooking something on their Jetboil stoves.

The ski down from the summit was mellow, and in the right snow conditions could possibly be great fun. We had some crusty snow which made things a little more challenging. For much of the downhill and flat sections after about 730m in altitude, the uptrack was my friend – keep the speed up was the name of the game.

Overall we felt that Mt. Kimobetsu, further up into the hills is a more exciting hill and worth the effort for the downhill. For a complete beginner, however, Mt. Kokimobetsu would likely be an enjoyable and challenging day out.
