Winter in Japan, From Tokyo's Sunny Days to Hokkaido's Snow

Pairing a big city with the snow country means a lot of checking on the go. A HelloRoam Japan eSIM, installed before you fly, turns each bullet train time, ski bus schedule or snow forecast into a quick tap.

Weather figures in this guide are JMA's 1991 to 2020 averages. Event dates, travel times and visitor counts come from the organizers and operators themselves, checked in October 2026, so confirm them on the official sites before you book.

Japan Has Three Winters: Mild Cities, Snow Country and Warm Okinawa

Snow rarely piles up in the big cities. Tokyo's official tourism site says snow generally falls in January and February but rarely settles, and JMA's normals count 2.8 days with snow in January and 3.5 in February. January is also Tokyo's sunniest month, with 192.6 hours of sunshine on average.

Hokkaido is a different trip. The Sapporo Snow Festival's own guide says the city's first snow comes in November, builds from late December and stays until March. Okinawa sits at the other end, with a January high of 68°F in Naha, so it suits mild sightseeing, not snow. Where to go depends on your goal: Sapporo and Otaru for snow festivals, Nagano for snow monkeys and Hakuba skiing, Niseko for powder and Abashiri for drift ice.

JMA Expects a Milder Winter Than Usual in 2026-27

JMA's outlook for December to February, issued on September 18, 2026, expects El Niño to last through the winter and cold air to have less effect on Japan than usual. It forecasts above-normal temperatures for eastern and western Japan, which include Tokyo, Kyoto and Osaka, and for Okinawa, with normal or above-normal temperatures in the north.

JMA also expects less snow than normal on the Sea of Japan side of eastern and western Japan. On the Sea of Japan side of the north, it expects normal or less snow.

A mild outlook doesn't rule out heavy snow. JMA's summary of last winter (December 2025 to February 2026) calls it warm across Japan but with big temperature swings. Even so, the Sea of Japan side of western Japan got 135% of its normal snowfall.

The Big Winter Festivals Fall Between Mid-January and Late February

These are the 2027 dates each organizer has published so far:

Shirakawa-go light-up. The World Heritage village of Shirakawa-go in Gifu lights up on four evenings in 2027: January 11, 17, 24 and 31, from 5:30 to 7:30 p.m. Its tourist association says entry is by advance reservation only, through a village stay, a parking space or a bus tour. No tickets are sold on the day.

Nozawa Onsen Dosojin Fire Festival. The village tourism association says this January 15 festival has about 300 years of history and is a nationally designated Important Intangible Folk Cultural Property. Men aged 25 and 42, ages treated as unlucky, guard a wooden shrine built without nails or wire. On the night of January 15, villagers try to set it on fire for about an hour and a half before the shrine is finally lit.

Yokote Kamakura. About 60 snow huts go up around Yokote, and children inside invite visitors in for amazake, a sweet rice drink, and rice cakes from 6 to 9 p.m. The custom honors a water god and goes back about 450 years. Yokote City moved the festival in 2026 from February 15 to the second Friday and Saturday of February, so check the dates in older guides.

Kitano Tenmangu plum festival. Kyoto's Kitano Tenmangu shrine has about 1,500 plum trees of 50 varieties. Its plum garden usually opens in early February, and the trees peak from late February to mid-March. The Baikasai festival on February 25 includes an outdoor tea ceremony served by geiko and maiko from the Kamishichiken district.

The Sapporo Snow Festival Runs February 4 to 11, 2027

The 77th Sapporo Snow Festival runs from Thursday, February 4 to Thursday, February 11, 2027. The last day is National Foundation Day, a national holiday. The festival uses three sites: Odori Park in the city center, the Tsudome sports center and the Susukino district. At Odori Park, five large snow sculptures are planned as the centerpiece, with the International Snow Sculpture Contest at the west end.

Expect crowds. The 2026 festival counted 2,539,000 visitors at Odori Park and Tsudome over its eight days, plus 1,378,000 at the Susukino ice sculpture site. That year also marked the 250th anniversary of the United States, with US-themed sculptures and snow attractions across all three sites and a visit from the US ambassador to Japan.

Getting there is simple. JNTO, Japan's national tourism organization, says dozens of flights a day connect Tokyo's Haneda and Narita airports with New Chitose, Sapporo's airport. The express train from there to Sapporo Station takes 35 minutes. From December 11, 2026, United also flies nonstop from San Francisco to Sapporo three times a week through March, so you can skip a connection in Tokyo.

Add an evening in Otaru, 30 minutes west of Sapporo by train. Its candle-lit Snow Light Path runs February 6 to 13, 2027, and the Blue Canal illumination runs along Otaru Canal from sunset to 10:30 p.m. from November 1, 2026 to January 31, 2027, the Otaru Tourism Association says.

Jigokudani's Snow Monkeys Bathe Mainly to Beat the Winter Cold

Jigokudani Yaen-koen, better known as the Snow Monkey Park, sits at 850 meters (about 2,790 feet) in the Yokoyu River valley in northern Nagano. The park says winter lows there drop below 14°F (minus 10°C) under more than a meter (over 3 feet) of snow. Wild Japanese macaques bathe in a hot spring pool the park built for them to get through that cold, though not at all hours and not in warm months.

The monkeys are wild, so they don't show up every day. The park posts a weekly appearance forecast and a live camera on its website. From December through April, visitors with online tickets get priority entry. Admission fees change on December 1, 2026, and winter hours (November to March) are 9 a.m. to 4 p.m.

To get there, the park lists the fastest Hokuriku Shinkansen from Tokyo to Nagano at 79 minutes. From Nagano Station, take the Nagano Dentetsu limited express to Yudanaka (38 minutes) and a 15-minute bus to the Snow Monkey Park stop. The express bus toward Shiga Kogen (41 minutes) also stops there. From there it's a 35-minute walk on an unpaved path, so wear boots with good grip.

Drift Ice Reaches Hokkaido's Okhotsk Coast Around Late January

Sea ice reaches Hokkaido's Sea of Okhotsk coast around the end of January, says the operator of the Aurora icebreaker in Abashiri. It explains that the ice forms where the Amur River empties into the Sea of Okhotsk, then spreads south. The company calls this coast, at 44 degrees north, the southernmost point where the ocean freezes, and runs its sightseeing cruises from January 20 to March 31.

Farther east, JNTO lists drift ice walk tours on the Shiretoko Peninsula, where you put on a dry suit and walk out onto the floes. Memanbetsu and Kushiro airports have direct flights from Tokyo's Haneda and Narita, JNTO says.

Niseko Logged 44 Feet of Snow in the 2025-26 Season

Niseko United, the four linked resorts of Annupuri, Niseko Village, Grand Hirafu and Hanazono, recorded 13.5 meters (44 feet) of snowfall in 2025-26. Fresh snow fell on 80 days, and January alone brought 6.2 meters (20 feet). The resort calls that season on par with recent winters, below heavier years such as 2020-21 at 15.9 meters (52 feet).

Two details help US skiers. Niseko United is on both the Ikon Pass and the Mountain Collective. Ikon days depend on your pass type, and Mountain Collective holders get two All Mountain lift tickets plus 50% off extra days, the resort says. JNTO puts Niseko two hours by train from Sapporo Station.

On the main island, JNTO points Tokyo-based skiers to Nagano. Hakuba Valley's 11 resorts get around 11 meters (36 feet) of snow a year. They open in late November and run until early May on the higher slopes, and January and February are the peak powder months. Nozawa Onsen's ski area, in the fire festival village, holds its 2026-27 season opening festival on December 19.

In the Kansai region, JNTO suggests Biwako Valley, in the mountains above Lake Biwa, as an easy day trip from Osaka or Kyoto.

Seven Days Covers Tokyo, the Snow Monkeys and Sapporo

This sample week links the sights above using the official travel times quoted in this guide. Shift it to catch the Sapporo festival (February 4 to 11, 2027) or the Nozawa fire festival (January 15).

• Days 1 and 2, Tokyo. Land at Haneda or Narita and spend two winter days in the city.
• Day 3, Nagano. Take the Hokuriku Shinkansen to Nagano (79 minutes at the fastest), then the train to Yudanaka (38 minutes), and stay nearby.
• Day 4, snow monkeys. Visit Jigokudani in the morning, then head back to Tokyo by train.
• Day 5, Sapporo. Fly from Tokyo to New Chitose and take the 35-minute train into Sapporo.
• Day 6, Otaru. Spend the day in Sapporo and the evening in Otaru, 30 minutes away by train.
• Day 7, home. Fly out of New Chitose, nonstop to San Francisco on United's winter schedule or via Tokyo.

With 10 days, add three nights at Niseko, two hours from Sapporo by train, or at Hakuba, by bullet train to Nagano and an express bus. With 14 days, add the drift ice at Abashiri from late January or Kyoto's plum season in late February.

Crowds Peak at New Year and Lunar New Year, Not All Winter

Winter isn't Japan's empty season. JNTO counted 3,597,881 foreign visitors in January 2026, close to April's 3,692,364. Fewer of them were American: 207,784 Americans arrived in January 2026, against 375,948 in March.

The busiest stretch is New Year. JNTO calls the year-end and New Year period extremely busy, with domestic travel at its peak and many businesses closed for several days from late December to early January. On January 1, crowds head to shrines and temples for hatsumode, the first visit of the year, and JNTO names Meiji-jingu Shrine as Tokyo's top spot for it.

Lunar New Year falls on February 6, 2027, during Sapporo's festival week, and JNTO's Hakuba guide calls Chinese New Year a particularly busy time on the slopes. Japan's own winter holidays in 2027 are January 1, January 11 (Coming of Age Day), February 11 (National Foundation Day) and February 23 (the Emperor's Birthday), the Cabinet Office says.

Your Phone Needs Data, Power and a Transit Card

Your US number can stay on for calls and texts while a HelloRoam travel eSIM handles data, since Apple says iPhone can keep both lines active. If setup stalls, 24/7 support can help. New to this? Here's how an eSIM works.

Before you buy, check that your phone supports eSIM and is unlocked. On iPhone, Apple says to open Settings, then General, then About, and look for "No SIM Restrictions" next to Carrier Lock. Then follow the step-by-step install guide at home before you fly.

When you land, iOS 26 may prompt you to Turn On Travel eSIM. Apple says that if you keep both lines on, the travel eSIM handles data, but your home line can still pick up roaming fees. To weigh that cost, see how eSIM and roaming costs compare. You can also choose the data line in Settings, then Cellular, then Cellular Data.

Cold is the winter catch. Apple says iPhone works best between 32° and 95°F (0° and 35°C) and that battery life can drop in very cold conditions, though only until the phone warms up again. Sapporo's average January high is 31°F, so keep your phone in an inside pocket and carry a charger.

To size a plan, estimate how much data you need for your trip. If several people will share one connection, compare pocket Wi-Fi versus an eSIM first.

For trains and buses, PASMO, one of Japan's transit IC cards, can live in Apple Wallet on iPhone. PASMO says most Android phones bought outside Japan can't run its mobile version, so Android users need the card. Its TOURIST PASMO for visitors is sold at Haneda and Narita airports.

Hokkaido's Icy Sidewalks Call for Winter Boots and Shoe Grips

JNTO says a warm winter jacket is a must anywhere in Japan in winter, and Tokyo's tourism site adds sweaters, gloves and scarves. Indoors is a different story: the Sapporo Snow Festival's guide notes that buildings are well heated, so wear layers you can take off easily.

Up north, the bigger risk is underfoot. The festival's advice for icy streets: wear winter shoes, add slip-on shoe grips and wear a hat and gloves. Grips are sold at convenience stores and the festival's official shops. Take care on crosswalks and where heated sidewalks end. During the festival, its official shops in Odori Park lend walking poles for free.

Outlets take Type A plugs at 100 volts, JNTO says, at 50 or 60 Hz depending on the region, so check the input range printed on your chargers. For the rest of your bag, work through our full travel packing list.
