Shokanso Hut and Mt. Shokanbetsu (署寒別岳 – 1,491m) Ski Touring (Hokkaido, Japan)


This ‘ski-by-numbers’ ski touring route is a beauty. The red ski-tour-specific trail markers, starting at #1 at Shokanso Hut (290m), make for relatively straightforward navigation up to around 1,000m in altitude. To summit Mt. Shokanbetsu (署寒別岳 – 1,491m) however, you’ll need near-perfect conditions and an early start. Right on the Japan Sea coast, this area is well-known for gale-force winds and low visibility at any time of the year, and there are no route markers from the 1,000m point on up to the featureless summit. That said, the warm and cozy Shokanso Hut is one of the best I’ve stayed in here in Hokkaido, and even with a dismal weather forecast, we managed to make the most of what this little slice of paradise had to offer.

Essential Info

  • Route GPS log: GPX file download.
  • Route timing: Around 2 hours from end of snowclearing (location) to Shokanso Hut (location). From the hut, bank on at least 4.5 hours to Mt. Shokanbetsu summit. On the way back, it is 1.5 hours on the descent from summit back to hut. From early April the road is cleared all the way to the hut, otherwise the hut is only accessible by ski.
  • Total climbing: 1,190m from the hut to Mt. Shokanbetsu summit
  • Topographical maps: For topographical maps, you can either print out what you want from the Geospacial Information Authority of Japan here (Mt. Shokanbetsu is in the cross-hairs), or buy the following 1:25,000 paper topo maps (for 350yen) from a bookstore in Sapporo (such as Kinokuniya next to Sapporo Station).
    • Shokanbetsudake (署寒別岳) – map no. NK-54-13-6-4
    • Shokanzawa (暑寒沢) – map no. NK-54-13-6-3
  • Snow safety: Mt. Shokanbetsu is known for its very strong winds as soon as you make it onto the ridge after route marker #50. Make conservative decisions when the wind is up and the visibility is low.
  • Other resources: See the write-up (in Japanese) on p. 302 of the Yuki-yama Guide (ISBN: 978-4894538047).
  • Best time to visit: Mid-April till mid-May (as per the Yuki-yama Guide). Earlier than this is considered deep-winter conditions, and you’ll have to access the hut from the mostly-flat snow-covered road. Which is precisely why I wanted to visit before the road to the hut was cleared. From Mid-April the hut becomes a bustling place for ski touring.
  • Getting there and away
    • By public transport: From central Mashike Town (accessible by bus from Sapporo and/or Rumoi), a taxi will likely cost around 2,500yen to the end of the snow-cleared section, probably twice that if going all the way to the hut in spring. Otherwise, there is no bus service or similar to the start of the route. Note: The Rumoi-Mashike JR train line was decommissioned in December 2016.
  • Onsen neaby: The closest onsen to Mashike Town is Auberge Mashike (location), which is not a natural onsen, but it is hot and wet – just what you need after three days in the hills. More importantly, it was open when we were there (unlike Attama-ru Onsen 15km down the coast – it is closed from November till March).
  • Other attractions: Mashike Town is known for its old early Hokkaido pioneer history and buildings. Don’t miss Hokkaido’s northern-most sake brewery (here), which has daily tours of the brewery and free sake tasting. We had an awesome seafood lunch on our last day at an old-school sushi restaurant (here) next to the old train station.

Shokanso Hut (Shokanbetsu, Mashike, Hokkaido, Japan)

Shokanso Hut (署寒荘) Essential Info

  • Location of Shokanso Hut: About 15km south from central Mashike Town (location). 
  • Details: The 3-storey Shokanso Hut, which sleeps 30, is a relatively new hut. It is a re-build of an older hut that was gutted by fire 53 years ago. It is maintained by the Mashike Town council, but managed by the informal Mashike Town mountain information center, run out of Cafe Polku (喫茶ポルク) as of February 2017. Until the second Friday in April each year, the access road to the hut is only cleared to around 5km before the hut. If visiting before they clear the road, you’ll need to allow 1.5 hours or so to trudge up the mostly flat road. If you’ve got a lot of food and gear, consider pulling it on a 700yen plastic sled – the Japanese skiers who were there when we were there did just that. There is no caretaker at the hut in the winter.
  • Booking: The hut is locked in winter. You’ll need to contact Cafe Polku (喫茶ポルク – kissa poruku) by phone on 0164-53-3839 to arrange to pick up a key to let yourself into the hut (be prepared to speak Japanese only). If communication with Cafe Polku doesn’t work, consider contacting the Mashike Town Office (Commerce and Tourism Department, TEL: 0164-53-3332) to find someone who speaks English and can relay to the cafe the time you plan to pick up the key.
  • Fee: Free.
  • Facilities
    • Heating: The hut is heated by a large wood stove. Wood is stored inside the hut, and there is extra stacked under the hut on the right-hand side looking towards the hut. Mr. Saito from Cafe Polku advised us that there was no newspaper in the hut for lighting the wood stove, but there was kindling.
    • Water: Running water is piped into the hut’s kitchen area from the small dam just above the hut. All drinking water must be boiled. IMPORTANT: Do not turn the tap off inside the hut. It is left running all winter to avoid the pipes freezing.
    • Kitchen/cooking: Pots and pans (including frypans), cutlery, cups, glasses, ceramic bowls and plates etc. are available for use. Wash and return after use. When we were there, there was a small portable gas stove (like this) available for communal/first-come-first-served use (bring your own non-threaded gas canister, like this). However, you’re better off assuming there is no cooking stove in the hut – bring your own. That said, the large wood stove heats water in kettles on the stove quite quickly (30 mins or so) if you get the stove hot.
    • Bedding: Officially, there are no mattresses or bedding in the hut. When we were there, however, there was about 10 sets of bedding including folding foam mattresses, futons, down quilts, and pillows, all available for use on a first-come-first-served basis.
    • Electricity: There is no electricity in the hut in winter.
    • Toilets: Toilets (with toilet paper) are inside the hut, and are basic long-drops.
  • Special Shokanso usage notes: The floor at eye-level in late winter is actually the second story. The entrance is 2 meters down, on the ground floor. Entering the hut, the toilets are on the left. Inside the hut proper you’ll be greeted by a stone floor area and the wood stove. This area is officially ‘outside’, so you can wear your boots in this area, store skis etc. In contrast, all wood floor surfaces are inside-shoes only, so either use the supplied slippers or your boot liners anywhere other than the stone floors. If you’re the first to arrive, the ground-floor windows will have wooden shutters covering them. These shutters hinge outwards and upwards, and are secured using the attached thin rope. Remember: Always leave a hut cleaner than you found it.

Climb and Ski Report

Preamble

Translated from the Japanese Yuki-yama Guidebook:

“With its extreme seasonal winds whipped up off the Japan Sea, the Mashike mountain range does not easily attract people during the mid-winter months. From afar, the mountains are cloaked in white down to rather low altitudes. This is testament to the harsh natural environment which stunts tree growth. It is not until mid-April – when the Shokanso Hut access road is cleared – that ski touring can really be enjoyed. If you want to stand upon the summit of Mt. Shokanbetsu, the Mashike Town side route is the shortest. But even then, you’ll be forced to spend a long time on the mountain.” Yuki-yama Guide, 2015, p. 302

On an overnight backcountry hut trip last year (to Mt. Okuteine Hut), an old Japanese guy told me about a hut on the way up Mt. Shokanbetsu, near the historic town of Mashike. In his experience, he rated the Shokanso Hut as the best in Hokkadio. “Not only is the hut amazing, but the skiing is fantastic,” he beamed. I was immediately intrigued. Mountain huts are an obsession for me, and so Shokanso Hut was duly filed away in my memory for another time.

Fast-forward to last week, and I finally stamped out some time to make the 250km trek from Sapporo to the small Japan Sea coast town of Mashike. I intentionally chose not to heed the Yukiyama Guide‘s recommendation to do the tour after the road to the hut was cleared. I love to feel isolated in a mountain hut, so I committed to making the 1.5 to 2 hour skin up the snow-buried road, making the trip a two-night, three-day trip.

Around the same time as I was planning to do the trip with or without companions (my usual ski-touring mates were not available that weekend), I got an email from a German couple – Hendrik and Leni – who were in Hokkaido for some split-board backcountry boarding. They had stumbled on my Hokkaido Ski Touring Resources page, and asked if I happen to have any trips planned in the next couple of weeks. If so, could they tag along? They seemed up to it, so I invited them to tag along with me to Mt. Shokanbetsu – to be co-explorers of a place I’d never been myself.

Day 1 – To the Hut

In the end, their Couchsurfing host in Sapporo, Hiro, also came along, and early on Friday the 24th of February, we found ourselves driving very carefully north from Sapporo along the Japan Sea coast towards Mashike. I say carefully because the very weekend I chose to do the trip, the entire island of Hokkaido was caught up in a massive storm. So massive in fact, that the high winds had cause waves to breach the road along the coast, closing the coastal road to Mashike. We had to make a 2.5 hour detour back inland via Takikawa and Rumoi in order to get to our destination. Even then, we were slowed at times to a crawl as great gusts of wind blew drifting snow across the road so thick that visibility was reduced to zero.

After finally arriving in Mashike, picking up the hut key from Cafe Polku, and getting to the end of the snow-cleared section of access road, we were running about 3 hours behind schedule. It was already around 1pm, so we’d likely be arriving at the hut around 3pm. We quickly suited up, and were amazed at how the Shokanbetsu River valley seemed to be nicely isolated from the raging storm elsewhere. There was hardly a breath of wind.

The 5km skin to the hut was a chance to re-acquaint ourselves with heavy packs on a ski tour. Inspired by prolific Hokkaido wilderness guide Leon Roode, I now like to make meals at mountain huts an event, rather than simply a necessity. This meant heavy packs for all of us. But I was determined to make it worth it.

Hiro seemed to have the right idea – a cheap 700yen plastic sled turned out to be the more popular way of lugging gear and food to this particular hut. We would discover other people at the hut that night, who had also used sleds to transport drinks, food, and home comforts to the hut with them. The relatively flat approach was definitely suited to this mode of moving luggage.

Just as Shokanso Hut came into view, we noticed interesting animal prints in the snow. They seemed to be from a fox-like animal, running around and around in circles. They had us scratching our heads until the pint-sized culprits came bounding towards us. There was another party already at the hut (they had been there three nights), and they’d brought along their hopelessly adorable shiba-ken Japanese dogs with them. They really looked like they were in their element – completely happy.

 The occupants of the hut were also surprised and excited to see us. There were four of them (three sisters and a older gentleman), and they’d been coming to Shokanso Hut for many years. They said that it was extremely rare that anyone else would stay at the hut during the season where the road was not cleared. It was lucky for us that they were there, as we were treated to the luxury of walking straight into a nice warm hut, the large wood stove already pumping out the heat.

On our menu for the first night was what I call ‘shabu-nabe‘. It is a fusion of two very similar communal meals in Japan – shabu-shabu and nabe. I tried to insist to the Japanese there that they are essentially the same thing – a large communal pot of very light soup into which pork, tofu, and vegetables are put in rounds, until a thick hearty soup remains. Into this goes udon noodles to finish.

The time taken to eat this meal makes it a very social event. There is time to check maps for the next day’s route, and there’s time to show off one’s nifty gadgets – such as Hiro’s new (and very powerful) alcohol stove.

Day 2 – If we can make it to marker #100 we’ve done well

It was an early night to bed the night before, so that we could make a very early start up the mountain. A quick breakfast of oats and coffee, and we were outside setting up by 7am. Before we had even set off, we collectively decided that we’d try to make it to the #100 marker, and assess the situation. Despite the very calm and kind conditions down at the hut, we all knew that the forecast was for very high winds at the higher altitudes, so we wanted to manage our expectations.

Mt. Shokanbetsu-dake Ski Touring (Hokkaido, Japan)

As we were setting off, a light snow started to fall, but there was certainly plenty of visibility to “join the dots”. The numbers on the trees below, 33-34-35 were an example of very closely spaced route markers. In other places, there were larger distances between markers, but not so far that even in quite heavy snow we were always able to find the next one to head towards.

It was not until marker #50 that we were on top of the northern ridge. It was here that we became increasingly acquainted with the strong winds that everyone told us about – including the other party at the hut the night before.

By marker #90, it was clear that we wouldn’t be making it far above 1,000m today. It became increasingly clear that the exposed slope at around marker #100 was no place to be, and we needed to head down as soon as possible. We threw on our down parkas, I filled my Nalgene bottle with boiling water from my thermos so that Hiro could warm up his cold, stiff hands, and the wind just kept hurling chunks of snow at us – even after I’d carved a large half-shelter in the snow for us to shelter for just a moment (whoever invented folding shovels with a ‘hoe’ function deserves a medal).

We were mostly smiles.

Due to the abysmal visibility and conditions, we were not in a position to consider other options for getting back to the hut other than back the way we had come. This was not a problem for me on my skis, and for the most part the boarders were fine also, but there were some flatter spots that required them removing their boards and hiking for a few meters.

To avoid one extra up at around 600m, we decided to drop down the western side of the main ridge at around 650m. This dropped us into more sheltered territory, but it was steep enough that we decided to stop to dig a pit and see how the snow pack looked like. Compression tests showed a very small weak layer under a harder melt-refreeze layer. Nothing catastrophically shifty however. The top layer, at least, was perfect for some very nice turns.

We were back in the warmth of the hut by just before 2pm. Grinning. Bubbling inside from the pure beauty of this valley. We were massively grateful to Mr. Kawai, the gentleman from the night before who had taken it easy today, and therefore had kept the fire stoked and warm.

Shokanso Hut (Shokanbetsu, Mashike, Hokkaido, Japan)

Of all the huts I’ve been to in Hokkaido, I think this is the one I was most happy to take a nap in that afternoon. The warmth of the fire, the snow falling softly outside the windows…pure luxury.

I slept lightly from 3:30pm till 4:30pm, as did Hiro. Leni spent her down time writing her diary, and Hendrik went out for some more turns, this time climbing up the west side of the valley directly across from the hut. “It was super steep,” he beamed, as he arrived back just in time for his curry and rice dinner.

Day 3 – Onsen, sightseeing, and back home

While the Shokanso Hut fireplace is great at warming up the hut, it doesn’t take long for the fire to burn out completely without any extra fuel. I stoked it once during the night, adding a couple of large pieces of wood. Despite this, I noticed in the morning Hendrik needed to use some newspaper to get the fire lit again.

Shokanso Hut (Shokanbetsu, Mashike, Hokkaido, Japan)

After a breakfast of scrambled eggs and bacon, we reluctantly bade our farewells to the hut. We washed up the dishes and returned them to the cupboards. We closed the ground floor window shutters. These all felt like ending rituals, drawing to a close a very peaceful and relaxing two nights at the hut.

Shokanso Hut (Shokanbetsu, Mashike, Hokkaido, Japan)

There isn’t much to say about the return from the hut to the cars. The route is long and flat. You’ll want your skins on right from the start.

Epilogue

No trip anywhere near Mashike should be without a little bit of sightseeing. We first got warmed up and washed at the Auberge Mashike hotel, which has an artificial onsen (550yen per person).

Afterwards, we had lunch at an amazing old-school sushi restaurant…

And Hiro and I got terribly jealous of Hendrik and Leni as they tried a number of local sake, during our tour of Japan’s northernmost sake brewery. A massive thanks to Hendrik, Leni, and Hiro for making this such a fun trip despite (or probably because of) the blustery weather.
