Which Japanese Prefecture Gets the Most Snow?

Ask which part of Japan gets the most snow and most people say Hokkaido. Most people are wrong, and the gap is not small.

We measured snowfall at every one of Japan’s 395 ski areas using one identical method, then averaged by prefecture.

The ranking

Prefecture	Ski areas	Average snowfall per season
Niigata	47	581 cm
Toyama	4	428 cm
Ishikawa	4	390 cm
Yamagata	17	371 cm
Fukushima	25	342 cm
Akita	17	333 cm
Iwate	11	333 cm
Aomori	9	310 cm
Fukui	3	309 cm
Nagano	65	300 cm
Gunma	24	272 cm
Gifu	16	260 cm

Niigata does not merely lead. It averages 36% more snow than second-placed Toyama, across a sample of 47 ski areas rather than four — which makes the figure far more robust than a single-resort record could be.

For scale: Niigata’s average ski area gets more snow than the single snowiest resort in Austria (325 cm), Switzerland (405 cm) or Germany (309 cm).

Why Niigata

Look at a map with the wind in mind.

Cold air pours off Siberia and crosses the Sea of Japan. It loads with moisture over warm water for a few hundred kilometres. Then it meets land — and the first thing in its way is the mountain wall that separates Niigata from the rest of Honshu.

Three things line up there and nowhere else does all three:

1. The sea is warm and the fetch is right. The air has enough distance over water to saturate, but not so much that it stabilises.
2. The mountains are close to the coast. Tens of kilometres, not hundreds. The moisture has not had a chance to fall out before the terrain forces it up.
3. The mountains are high enough. 2,000 m of forced ascent wrings out essentially everything.

Move the mountains inland and you get less. Cool the sea and you get less. Niigata sits at the exact intersection.

But Hokkaido has the reputation

Hokkaido’s snow is drier, because Hokkaido is colder. That is a real and important difference — dry snow is what people travel for, and it is why Niseko became an international destination while Yuzawa did not.

But by volume, Honshu’s Sea-of-Japan coast wins clearly. Niseko sits at world rank 414 in our global ranking. Nine Niigata ski areas sit in the world top twenty.

The distinction worth holding onto:

• Niigata — the most snow, heavier, lower elevations, occasional rain at the base
• Hokkaido — less snow, but colder and drier, and more reliable snow quality

What is actually in Niigata

The prefecture’s ski areas are not obscure because they are bad. They are obscure because they were built for Tokyo weekenders arriving by train and never needed foreign visitors.

• Yuzawa — a cluster of a dozen areas around a Shinkansen station 75 minutes from Tokyo. Four of them tie for fourth snowiest on earth.
• Myoko — the biggest vertical in Japan at Suginohara, with Seki Onsen (world #8) and Charmant Hiuchi (tied world #10) nearby.
• Okutadami Maruyama — world #1, and so buried that it only opens in spring.
• ARAI — tied world #10, reopened in 2017 after two decades closed, now with a serious lift and a tree-skiing policy.

The runners-up are worth a look too

Toyama at 428 cm has only four ski areas, but they sit beneath the Tateyama range — the same mountains that feed Japan’s steepest river and hold the famous spring snow corridor at Murodo, where walls of cleared snow stand many metres high into April.

Yamagata at 371 cm has Zao, with its juhyo — the snow-and-rime-covered fir trees known as snow monsters — and Mount Gassan, which does not open until April and runs into summer.

How this was measured

Daily snowfall summed across the three most recent completed seasons — 2023/24, 2024/25 and 2025/26 — then divided by three, for all 3,108 ski areas worldwide. Source: Open-Meteo historical data from the ERA5 reanalysis. We use recent seasons rather than a thirty-year normal because snowfall patterns are shifting.

Two limits matter. The model grid is 10–30 km across, so ski areas in the same valley share a value — this ranking cannot separate neighbours, only regions. And three seasons is a short record, with year-to-year swings large enough that small gaps are noise.

Prefecture averages are more reliable than individual resort figures for exactly that reason: averaging 47 ski areas across many grid cells cancels out much of the error. The Niigata-versus-Toyama gap, and the Japan-versus-Europe gap, are far too large to be artefacts.
