Myoko's Snowiest Ski Area Is 14th in Japan. The One on the Ikon Pass Is 101st.

Myoko is the other name people reach for when Hakuba and Niseko are full. It is not one ski area. Eleven sit within 16 km of Akakura, and the gap between the snowiest and the driest is almost two to one.

The one most foreign skiers end up at is at the dry end of that gap.

Snowfall is ours, measured identically at all 397 Japanese ski areas over twelve winters. Snow quality is our own index — how cold it is when it snows, how often more than 5 cm falls, how often it rains instead, and the wind. Snowfall volume is deliberately not an input, which is why the two columns disagree.

Seki Onsen is the one the numbers point at

Seki Onsen is the only ski area in Myoko that is in Japan’s top 50 for both columns, and one of only nine in the whole country. The other eight are in Hakuba, Yuzawa, Togakushi and Yamagata.

The components say why. Snow falls there at −4.2 °C, rain reaches it on 17% of winter days, and 38% of its winter days deliver more than 5 cm — the highest share of any ski area in the area. For comparison, Suginohara’s figure is 23%.

It is also volatile. Across twelve winters Seki ranged from 273 cm to 867 cm, with a median of 732 cm. A good winter there is enormous; a bad one is ordinary.

Why the three snowiest do not all score well

Charmant Hiuchi and Arai sit a few hundred metres above the Sea of Japan and catch the full weight of the winter monsoon. They also catch the warmth of it: snow falls at −2.0 °C and −2.2 °C respectively, and rain reaches both on 29% of winter days — nearly one day in three.

That is the trade the whole Sea-of-Japan coast makes, and it is the reason our quality index exists. 690 cm that arrives at −2 °C with rain every third day is not the same product as 689 cm that arrives at −4.2 °C.

Suginohara is the mirror image. It gets the least snow of the eleven and the coldest and driest of it: −4.4 °C on snowing days and rain on 12% of winter days, the lowest in the area. That is what a top station at 1,855 m buys.

What each one is for

You want the deepest snow and do not mind a small operation. Seki Onsen. Top of the area for snow and 30th in Japan for what that snow is like.

You want a big mountain and a long run. Myoko Suginohara. Its own figures: 16 courses, a longest run of 8,500 m and 1,124 m of vertical — both larger than Hakuba Happo-One’s 8,000 m and 1,071 m. It is on the Ikon Pass. The season runs 19 December to 28 March, shorter than its neighbours. Accept that it gets the least snow of the eleven and the best quality of it.

You want steep. Akakura Kanko. Nine courses, and by its own grading only one of them is a beginner run — the other eight are intermediate or advanced, with a maximum pitch of 32° on Champion A, which it leaves ungroomed. One gondola and five chairlifts. Day ticket ¥7,000.

You are bringing small children. Akakura Kanko has a netted “chibikko hiroba” for sledding below the hotel slope. Ikenotaira Onsen runs a Kids Garden at weekends and holidays, 10:00–16:00, ¥500.

You want the bath on site. Ikenotaira Onsen has a day-use hot spring inside the resort. More broadly, Myoko is one of the densest clusters of analysed hot spring sources near ski areas in Japan — Seki Onsen has a 52 °C source 400 m from the lifts.

You want tree runs. Madarao, which claims the most tree-run courses in Japan on its own site, and Tangram next to it — the two share a mountain and a joint ticket.

What this does not tell you

• Neighbouring areas share a weather grid cell. The three Akakura-area figures are identical at 445 cm, and four more read 432 cm. That is the resolution of the model, not a measurement of four identical mountains. The spread across the area — 357 cm to 690 cm — is much larger than the grid spacing and is real.
• The model runs below what resorts report. Against Japan Meteorological Agency stations it returns roughly half of what the ground records. Read the ordering, not the centimetres.
• We have confirmed facilities only where the operator describes them. Three of the eleven are covered in detail so far: Suginohara, Akakura Kanko and Ikenotaira Onsen. A ski area not listed above as having a kids park or a bath may well have one.
• Ikenotaira Onsen was missing from this site until 2 October 2026. It had been dropped by a deduplication rule of ours, not by the data. It is one of Myoko’s main ski areas and it is now measured like the rest.

How this was measured

Snowfall is the December–March total at each ski area’s coordinates from ERA5 reanalysis via the Open-Meteo Historical Weather API, averaged over the twelve winters from 2014/15 to 2025/26 and measured identically at every ski area on this site. December figures are the 1–31 December total on Japan time, averaged over the same twelve.

Snow quality is our own index across all 397 Japanese ski areas: dryness (temperature on days snow falls) multiplied by frequency (share of days over 5 cm), with penalties for rain days and wind. The weights are our judgement, not a measurement; what the ranking carries is that every ski area went through one identical calculation.

Courses, lifts, gradients, ticket prices, season dates and kids facilities are each resort’s own figures, read on its own website on 2 October 2026. We publish no forecast of our own; for conditions before you travel, check the Japan Meteorological Agency and the resort.
