When Does It Snow in Japan? First Snow Dates, Snow Depth and Where to Actually See It

Two numbers that break most people's mental model of Japanese winter. Tokyo's average first snow falls on January 3 — later than Osaka's December 26. And Aomori averages 567 cm of snowfall a winter while Tokyo gets about 8 cm a year, a gap of nearly seventy times. "When does it snow in Japan" is really three separate questions: when does snow first fall, when does it stick, and will I see any during my week. This guide answers all three using Japan Meteorological Agency 1991-2020 normals — first snow, last snow and first snowcap dates for 14 cities, plus snowfall totals and snow depth for six — and clears up the two things visitors get wrong most often: first snow versus first snowcap, and whether it really snows in Tokyo.

⚠️ Read this first: every date and centimetre below is a JMA "1991-2020 normal" — a 30-year statistical average — not a forecast for the 2026-27 winter. Japan's first official outlook covering the whole cold season is the cold-season forecast, scheduled for 14:00 on September 18, 2026; three-month forecasts covering December to February follow on January 19 and February 22, 2027. Until then no official winter snowfall outlook exists, and this site does not invent one. Use this page to frame the shape of a trip, then check the live official pages closer to departure.

What "first snow" officially means in Japan

Every late autumn, Japanese news starts announcing "first snow in city X," and travellers immediately assume it is time to book. That is the misunderstanding this guide most needs to intercept.

The JMA defines hatsuyuki (first snow) as the first day in a cold-season year — August through the following July — that the local weather station observes falling snow. Two details matter enormously. First, sleet counts: a few minutes of half-rain, half-snow satisfies the definition. Second, no accumulation is required. On the average first-snow day you could stand in the middle of the city and see a handful of flakes dissolve before they reach the pavement.

So answering "when does it snow in Japan" with the first-snow date badly overstates what you will actually see. What determines whether there is snow scenery is snowfall volume and snow depth — a completely different data set, laid out in section 4.

One clarification worth making, because it circulates as misinformation. The JMA did sharply cut back its phenological observations from 2021 (cherry blossoms, maples and the like, with all animal species dropped). First snow, last snow and first snowcap were not part of that programme. They are atmospheric-phenomenon observations, they were not discontinued, and they are still compiled — the 1991-2020 normals used throughout this article are the proof. Two related changes did happen: some stations moved to automated instrument observation (the Aomori Local Meteorological Office states that from the 2021 cold-season year its first-snow observation switched from staff visual observation to automatic instruments, with normals recalculated using corrected data from the visual-observation period to keep the series comparable), and some unstaffed "special regional weather stations" no longer perform observations that require a human eye, such as frost, ice and snowcap.

First snow vs first snowcap: the 52-day trap

The second frequent mix-up is treating hatsukansetsu (first snowcap) as if it were first snow.

First snowcap is officially the day a mountain summit visible from the weather station is first seen capped with snow. It is about the mountain, and it must actually be visible — if cloud hides the peak on the day it whitens, the record waits. Because summits cool far earlier than the plains, snowcap normally precedes first snow by a wide margin.

Toyama proves the point better than any explanation. From the same weather station and the same normals table: Mt. Tateyama's first-snowcap normal is October 12, while Toyama city's first-snow normal is December 3 — a 52-day gap. Book a flight the week you read "Tateyama has its first snowcap" and you will arrive nearly two months before the city sees a flake.

Asahikawa is the other headline generator. Mt. Asahidake's first-snowcap normal is September 25, genuinely among the earliest snow sightings on the Japanese mainland — but that is a 2,291-metre summit. Asahikawa city itself does not reach its first-snow normal until October 19, nearly a month later.

The practical rule: read the first-snow column, not the snowcap column, unless you were planning to go up a mountain anyway. Note too that not every station observes snowcap at all. Tokyo, Osaka, Kyoto, Nagoya and Niigata have no snowcap entry in the normals table because no suitable mountain is visible from the station.

First and last snow dates for 14 cities

This table is the core of the article. Source: JMA "normals for the first and last dates of frost, snow and ice, and first snowcap," statistical period 1991-2020 (30 years), checked station by station. Ordered north to south.

Source: Japan Meteorological Agency normals for frost, snow, ice and first snowcap, statistical period 1991-2020. Retrieved August 2, 2026.

Four readings worth pulling out of that table:

• Tokyo snows later than Osaka. January 3 against December 26, eight days apart, even though Tokyo sits further north. Tokyo's urban heat island and its Pacific-facing warm current lift local temperatures, while Osaka occasionally catches snow clouds that spill over the mountains from the Sea of Japan side. The intuition that "further north always snows earlier" simply does not hold between Japan's big cities.
• Last-snow dates run later than most people assume. Asahikawa's last-snow normal is May 1, Sapporo April 21, Aomori April 15. Northern Japan is statistically still within snow range around Golden Week. If you are heading north in spring, do not pack to a Honshu standard — region-by-region gear is covered in what to wear in Japan by season and region.
• Fukuoka gets snow, and it is not a freak event. First snow December 16, last snow March 7 — a window of nearly three months. Kyushu in winter is not automatically snow-free, which trips up a lot of itineraries.
• Kagoshima has the shortest season on the table, running from a January 5 first snow to a February 17 last snow: roughly six weeks end to end.

First snow across Hokkaido (different statistical period)

A separate regional compilation fills in Hokkaido cities the main table omits. Its statistical period is August 1990 to July 2020, slightly different from the 1991-2020 definition above, so do not merge the two into one comparison.

Wakkanai Oct 19, Asahikawa Oct 19, Kutchan Oct 20, Rumoi Oct 25, Abashiri Oct 30, Otaru Oct 31, Hakodate Nov 1, Obihiro Nov 1, Kushiro Nov 7.

Practically the whole island reaches first snow between late October and early November, meaning Hokkaido at the end of October is already inside snow range. Same caveat as ever, though: first snow is not accumulation, and what you would most likely see in late October is a brief flurry that vanishes.

Snowfall totals, snow depth and long-term snow cover

Once you know when snow starts falling, this is the data set that decides whether you will see snow scenery. Same source, statistical period 1991-2020.

Centimetres. Source: JMA annual and monthly normals, statistical period 1991-2020, retrieved August 2, 2026. Tokyo's annual figures are given as approximations because the decimal place could not be confirmed to our own standard.

Two things to take from that table.

First, the gap is an order-of-magnitude gap. Aomori receives 567 cm in a winter; Tokyo about 8 cm in a year. That is not "a bit more up north," it is a different country climatically. Which leads to my flat recommendation: do not gamble on Tokyo snowing. Spend the money on getting to snow country instead.

Second, January is the nationwide peak. Aomori's January snowfall of 195 cm, Sapporo's 137 cm and Toyama's 104 cm are each that city's snowiest single month. If you can choose your travel month freely, mid-January to mid-February is when snowfall and accumulated depth both line up. Early December is the classic disappointment window — technically past the first-snow date in much of the north, but the base has not built up yet.

One more reading trap. The "annual max snow depth" figures (Aomori 32 cm, Sapporo 34 cm) look absurdly small next to the snowfall totals, because snowfall is cumulative over a season while depth is what is measured lying on the ground at a point in time — snow compacts, melts and gets ploughed away. Aomori's 567 cm does not mean five-metre walls along the street; the observed normal maximum is around 32 cm. The towering banks you see in photos are ploughed piles, not observation values.

"Long-term snow cover": the official line between snow and snow that stays

Japanese has a word, neyuki, for the snow that falls one day in winter and simply never melts until spring. The JMA's statistical term is not neyuki but "long-term snow cover," generally understood as snow lying continuously for 30 days or more, compiled only for staffed observation points in northern Japan where such cover is common.

Here I have to be straight about a limitation. The primary text of that definition sits in Chapter 4 of the JMA's Guidelines for Meteorological Observation Statistics, under the method for calculating long-term snow cover, and I could not retrieve a readable copy during verification. What exists are several independent secondary sources that agree on the 30-day core. So this article states only that core concept. The continuation rules and any city-specific long-term-snow start and end dates are deliberately omitted until the official text can be read. If another site hands you a precise "snow cover in Sapporo begins on date X," judge the sourcing for yourself.

The concept is still useful for planning, because of one delightful detail: the start date of long-term snow cover is not announced on the day. It is assigned retroactively, once the cover has actually lasted 30 days. Ask early in the season whether the permanent snow has started and even the JMA cannot answer. The practical takeaway is that chasing this statistic is pointless for a traveller — check the live snow page in section 7 instead.

Does it snow in Tokyo? The honest answer

This is the single most-searched version of the question, so here is the answer up front: yes, but on an average of six days a year, and it almost never sticks.

Translated into traveller terms: on a five-day Tokyo stay, the statistical odds of catching snow sit somewhere between one in twenty and one in ten, and the snow you catch will most likely melt on contact. December is worse still — Tokyo's December snowfall normal is zero, meaning the city has not statistically reached its first snow by Christmas. A snowy Tokyo December is a film set, not a climate.

The real Tokyo snow problem is infrastructure, not volume

What deserves your attention is what happens when Tokyo does get snow. The official warning thresholds tell the story. Per the JMA's table of special-warning indicators and warning and advisory issuance criteria for the Tokyo District Meteorological Observatory area — the PDF states its own version as of May 28, 2026:

Ten centimetres in twelve hours triggers a heavy snow warning — a threshold that would not make the local news in Hokkaido. The difference is infrastructure: Tokyo has almost no road-heating, ordinary cars run summer tyres year-round, and pedestrians own no snow boots. The same snowfall is routine in Sapporo and a civic emergency in Tokyo. If you are there on that day, knowing what Warning Levels 1 to 5 ask you to do matters more than the centimetre count — and those alert names were all rewritten on 29 May 2026.

The most recent example is the south-coast low of January 22, 2018, when Tokyo recorded 23 cm of snow depth — the first major central-Tokyo snowfall in four years, since the 2014 event. Multiple metropolitan expressway sections closed and airports saw large-scale cancellations and stranded passengers. More precise figures circulate online for accident counts and stranded traveller numbers, but I could not match them to the JMA's own disaster report, so this article keeps the description qualitative.

Historically, deep snow in central Tokyo has always been rare. The all-time maximum snow depth ranking is led by 46 cm on February 8, 1883, then 38 cm on February 22, 1945 and 36 cm on February 23, 1936 — the entire top three predates the war. The most recent entry to crack the top ten is 27 cm on February 15, 2014, sitting in eighth place.

Practical advice: if a heavy-snow forecast lands on your Tokyo dates, move airport transfers and shinkansen legs a day earlier rather than travelling on the day itself. And if you want snow within a day trip of Tokyo, the realistic options are covered in winter day trips from Tokyo.

Where to go for snow, and when

One disclaimer before the list: this section is not written for skiers. If you want snow quality, resort comparisons and lift-pass maths, go straight to the Japan ski resort comparison. What follows is for the traveller who simply wants to see and photograph snow without strapping anything to their feet.

Timing below is derived from the two normals tables above. Every window is a statistical peak, not a promise.

Routing a snow-chasing trip

If you have the days and want two different kinds of snow in one trip, I would run Tohoku first (Zao, Ginzan, Aomori), then Hokkaido. Both regions peak from mid-January to February, but southern Tohoku's season closes earlier, so working south to north avoids arriving back to a thaw. If your flights are fixed in and out of Tokyo, the simpler shape is to use Tokyo as a base and run two separate shinkansen legs — one to Echigo-Yuzawa, one into Tohoku.

First snow sweeps from Asahikawa on October 19 to Tokyo on January 3, two and a half months apart, which means seeing two or more snow regions on one trip almost guarantees long-distance shinkansen legs. Across several of them a nationwide JR Pass on KKday usually beats buying leg by leg, while a single region is better served by a regional pass — break-even maths and four worked routes are in the JR Pass guide 2026.

Driving instead? Read winter driving in Japan first — snow tyres, whiteouts and hill starts are outside this article's scope and covered far better there. For the seasonal food side of a snow trip, see Japan winter food guide.

How to check snow yourself: the official pages

Normals give you the skeleton. What decides whether you can leave the hotel on a given morning is live data — and Japan has an excellent official tool that almost no foreign visitor uses.

All three pages are Japanese-only, with no English versions — but they are map-driven and colour-coded, so the language barrier is lower than it looks. The genuine barrier is connectivity: an hourly-updating page is worthless if you are standing in snow country with no data. Wi-Fi coverage on regional buses, in subway stations and in mountain ryokan lobbies is patchy, so activating a Japan eSIM on KKday before departure beats hunting for a SIM counter on arrival. Five providers compared in the Japan eSIM guide 2026.

What shuts down for winter: Tateyama Kurobe and Kamikochi

"When does it snow in Japan" has an inverse that catches people out: some of the most photogenic mountain destinations close completely for the snow season, and they close for a long time. These two cause the most trouble:

The shared misconception is "it snows a lot there, so winter must be the time to go." In fact the snow is precisely why they close. Tateyama Kurobe's following-season dates are typically announced between the preceding winter and early spring; at the time of writing the 2027 dates are not published, so treat the 2026 window as a rough guide and do not book flights on it. Kamikochi's closing-ceremony date is not stated on the official news page, and the dates circulating online could not be matched to an official source, so this article says only "closes in mid-November." Access and how to work the route once it reopens are in the Kamikochi access guide.

Also worth flagging: many ropeways run annual maintenance closures, most commonly in November, with each operator setting its own dates — check the specific facility's site before booking. For the wider "which season should I visit at all" question, compare the best time to visit Japan and Japan weather month by month.

The 2026-27 winter: official release schedule

Which brings us to the question everyone actually wants answered: will the 2027 winter be a big snow year?

This site does not forecast that, and right now there is no official version to cite either. What is useful is the schedule:

The implication is blunt: before September 18, 2026, any claim that "this winter will be snowy" or "this winter will be mild" is not an official forecast. Every autumn, reasoning of the form "it is an El Niño year, so expect a mild, low-snow winter" circulates online. El Niño and La Niña are monitoring of sea surface temperature conditions, separated from snowfall in any particular Japanese city by several layers of atmospheric process, and they cannot be translated directly into a snowfall prediction. The JMA itself does not attach Japanese winter snowfall conclusions to its El Niño monitoring bulletins.

There is a deeper limitation too. Even after the official outlook lands on September 18, what it provides is probabilities of above- or below-normal temperature and snowfall tendency — not "it will snow in Sapporo on January 20." Seasonal forecasting simply does not resolve to individual days. The workable approach is three-stage: use the normals on this page to choose a month, use the weather forecast one to two weeks out for direction, and use the JMA live snow page on the day for the next six hours.

This page will be revisited after the September 18, 2026 release, at which point it will add only "the official outlook is out, here is where to read it and how to interpret it" — it will not restate forecast numbers as if they were this site's prediction. For the fixed calendar dates of winter events (snow festivals, illuminations, icebreaker sailings), there is a separate hub: Japan in winter.

Frequently Asked Questions

Q1：When does it start snowing in Japan?

It depends entirely on the city, not the month. Using Japan Meteorological Agency 1991-2020 normals, the earliest first-snow dates on the mainland are Asahikawa on October 19 and Sapporo on October 28. Northern Honshu follows in early November (Aomori November 8, Sendai November 17), the Sea of Japan coast in late November to early December (Niigata November 23, Kanazawa November 24, Toyama December 3), and western Japan plus the big tourist cities only in mid to late December (Kyoto December 11, Fukuoka December 16, Nagoya December 18, Osaka December 26). Tokyo is the latest of all at January 3. These are 30-year averages, not a forecast for any given winter.

Q2：Does it snow in Tokyo?

Yes, but far less than most visitors expect. By JMA 1991-2020 normals, Tokyo averages first snow on January 3 and last snow on March 9, with just 6 snowfall days per year (3 in January, 3 in February), roughly 8 cm of total annual snowfall and a maximum snow depth of about 5 cm. December snowfall in Tokyo averages zero, so a snowy Tokyo Christmas is statistically not a thing. The bigger issue is not whether you will see snow but what happens when snow does fall: Tokyo has very little tolerance for it.

Q3：What is the difference between first snow and first snowcap?

First snow (hatsuyuki) is the first day the weather station observes falling snow, including sleet. It only requires that something frozen fell from the sky; no accumulation is needed. First snowcap (hatsukansetsu) is the first day a mountain summit visible from that weather station is seen covered in snow. Because summits cool earlier, snowcap almost always comes first. Toyama is the clearest example: the same station reports a first-snowcap normal of October 12 for Mt. Tateyama but a first-snow normal of December 3 for the city itself, a gap of 52 days.

Q4：Where and when should I go to see snow that actually sticks?

Mid-January through February on the Sea of Japan coast or in Hokkaido is the reliable answer. By JMA 1991-2020 normals, annual snowfall totals are 567 cm in Aomori, 479 cm in Sapporo, 253 cm in Toyama, 157 cm in Kanazawa and 139 cm in Niigata, against roughly 8 cm in Tokyo. January is the single snowiest month nationwide (195 cm in Aomori, 137 cm in Sapporo). Build the core of a snow trip around mid-January to mid-February in Tohoku or Hokkaido and your odds are far better than betting on Tokyo.

Q5：Will the 2027 winter be a heavy or light snow year?

Nobody can tell you yet, and this site does not make its own forecast. The first official Japanese outlook covering the whole cold season is the JMA cold-season forecast, scheduled for release at 14:00 on September 18, 2026 alongside the three-month forecast. Three-month forecasts covering December to February follow on January 19 and February 22, 2027. Before September 18 there is no official winter snowfall outlook. Also note that seasonal forecasts give probabilities for temperature and snowfall tendency, not dates on which snow will fall.

Q6：Which month guarantees snow in Japan?

None. Meteorologically there is no guarantee, only probability. What does exist is a JMA statistical concept usually rendered as long-term snow cover, generally understood as snow lying continuously for 30 days or more, compiled only for observation points in northern Japan. In plain terms it marks the stretch when snow in the north simply stops melting. Travel-wise that maps to roughly January through February in Hokkaido and the Sea of Japan side of Tohoku. Even in Sapporo, whether it snows on one specific day remains a probability, so check the JMA live snow page before you head out.

📚 Once you know when it snows, the next two questions are what to wear and what to do. Region-by-region gear is in what to wear in Japan; monthly temperatures and travel highlights are in Japan weather month by month; fixed winter event dates are at the winter hub.
