December is one of the most underrated months to visit Japan. Skies in Tokyo are usually clear and dry, cities are covered in winter lights, the ski season starts in the north, and the autumn crowds have gone. The one thing to plan around is the New Year holiday at the very end of the month, when prices peak and many businesses close.

Quick answer: Early to mid-December (about 1–20 December) is the sweet spot: cool, mostly sunny weather in Tokyo and Kyoto (daytime highs of around 10–12°C), illuminations and Christmas markets in full swing, and normal prices. Book ahead if you'll be in Japan on 23–25 December (some illuminations need advance tickets) or from about 27 December (New Year trains and hotels). Heading to Hokkaido? Expect snow and highs around 2°C.

December weather in Japan

Japan stretches a long way north to south, so "December weather" depends heavily on where you are. The figures below are long-term averages from the Japan Meteorological Agency (1991–2020 normals), rounded. Any single year can be warmer or colder.

City	Average high	Monthly average	What it feels like
Tokyo	About 12°C	About 8°C	Crisp, sunny, dry; cold after dark
Kyoto / Osaka	About 11–12°C	About 7–8°C	Similar to Tokyo, chillier mornings in Kyoto
Sapporo	About 2°C	About −1°C	Snowy; icy pavements, real winter

For Tokyo, Kyoto and Osaka, a warm coat, layers and comfortable shoes are enough. For Hokkaido or the Japan Alps, you'll want a proper winter jacket, gloves, a hat and shoes with good grip. Indoors (trains, shops, restaurants) is often heated well, so layers you can take off are more useful than one very thick sweater.

Best illuminations and Christmas markets in December 2026

Japan's winter illuminations ("irumineshon") are a big part of the season. Most city displays switch on from mid- or late November, and many of the Christmas-themed ones end on 25 December, so December is the month when nearly all of them are running at once.

Tokyo Christmas Market 2026: two sites this year. The new Shin-Toyosu site runs 20 November to 25 December, and Shiba Park (by Tokyo Tower) runs 4 to 25 December. Entry for adults is about ¥1,000 on weekdays and ¥1,500 at weekends, with higher prices on 24–25 December. Check the organiser's site for ticket rules before you go.
Sapporo White Illumination: the Odori Park venue runs 20 November to 25 December 2026, while other central Sapporo venues stay lit into February or March 2027. It's free.
Nabana no Sato (near Nagoya): one of Japan's biggest light shows, famous for its long tunnel of lights. The season runs from autumn into spring. In the 2025–26 season, visiting from 15:00 on 23–25 December required a date-specific ticket bought in advance, so expect similar rules for Christmas 2026 and check the official site.
Kobe Luminarie is no longer a December event: the 2027 edition is scheduled for 29 January to 7 February 2027.

Nabana no Sato is awkward to reach by public transport in the evening, which is why many visitors join a bus tour from Nagoya that combines it with outlet shopping.

December events and holidays

Date	What happens	What it means for you
2–3 December 2026	Chichibu Night Festival (Saitama), with giant lantern-lit floats and fireworks on the 3rd	Very crowded trains from Tokyo; plan your return in advance
Early–mid December	Ski resorts in Hokkaido and Nagano start opening, depending on snow	Early-season snow is not guaranteed; check resort opening dates
24–25 December	Christmas: a romantic date night in Japan, plus the famous KFC Christmas dinner	Popular restaurants and illuminations are busy; book dinners early
About 27–30 December	Year-end exodus from big cities	Shinkansen and flights are packed; reserve seats
31 December	New Year's Eve: temple bells (joya no kane) and first shrine visits after midnight	Some city train lines usually run late or all night; check timetables

Christmas is not a public holiday in Japan, so shops, museums and transport run normally on 25 December. The real holiday is New Year: government offices traditionally close from 29 December to 3 January, and many small restaurants, some museums and some shops close for a few days around 1 January. Convenience stores, big chains, department stores (often with New Year "lucky bag" sales from 1 or 2 January) and most major sights stay open.

What to book before a December trip

Most of December needs little advance planning. These are the exceptions:

Anything on 23–25 December: Christmas Eve dinners, popular illuminations with advance-ticket days, and hotels in date-night areas.
Trains and hotels from about 27 December: reserved Shinkansen seats generally go on sale one month before travel. Book on the first day for peak dates.
Ski trips and snow tours: lift tickets, gear rental and airport transfers, especially over New Year. Our winter booking guide covers Shirakawa-go, the Sapporo Snow Festival and snow monkeys in more detail.
Mobile data: maps, train apps and translation matter more in winter, when daylight ends around 16:30. A Japan eSIM set up before you fly means you're online from the moment you land.

Snow monkeys at Jigokudani are at their most photogenic once the snow arrives, and the park now uses timed online tickets for peak winter months. A day tour from Tokyo bundles the transport and entry.

Pros and cons of visiting Japan in December

Pros: stable, sunny weather on the Pacific side; illuminations and Christmas markets; fewer crowds and lower prices than autumn-leaf season in early December; start of ski season; hot springs feel their best.
Cons: short days (sunset around 16:30 in Tokyo); late-December price spikes and closures around New Year; snow can disrupt travel in the north and on the Sea of Japan coast; early-season ski conditions vary.

If you're driving in Hokkaido, winter tyres come as standard on rentals there, but icy roads still take real care. Read our Hokkaido car rental guide before booking a car.

Frequently asked questions

Is December a good time to visit Japan?

Yes, especially the first three weeks. The weather in Tokyo, Kyoto and Osaka is cool and usually dry, illuminations are everywhere, and prices are normal until the New Year rush starts around 27 December.

Does it snow in Tokyo in December?

Rarely. Snow in central Tokyo is uncommon in December and more likely, though still occasional, in January and February. For reliable snow, go to Hokkaido, Tohoku or the Japan Alps.

Can I still see autumn leaves in December?

Sometimes, in early December. In recent years leaves in Tokyo and Kyoto have often lingered into the first week or so of December, but it varies by year and by spot. Check our autumn leaves 2026 guide for forecasts.

Is everything closed in Japan over New Year?

No. Many small family-run restaurants and some museums close for a few days around 1 January, but convenience stores, chain restaurants, big department stores, trains and most major shrines and sights stay open. Shrines are at their busiest on 1–3 January.

Bottom line

For the best mix of weather, lights and prices, aim for 1–20 December. If your trip covers Christmas or New Year, book the few things that sell out (advance-ticket illuminations, holiday dinners, Shinkansen seats and hotels) as early as you can, and leave the rest flexible.
