"How cold is Japan in winter?" The honest answer is: it depends where you go. Tokyo in January feels like a crisp, sunny autumn day by noon but drops close to freezing at night. Sapporo stays below freezing for weeks. And wherever you are, you will step from icy streets into heated trains, department stores and restaurants dozens of times a day. Packing for a Japanese winter is less about the warmest possible coat and more about layers you can take off and put back on.
This guide explains what to wear in Japan in winter, city by city, using official average temperatures, along with footwear tips and the things that are cheaper and easier to buy once you arrive.
1. How Cold Is Japan in Winter?
Japan's winter runs from December to February. These are the Japan Meteorological Agency's average daily highs and lows for each winter month. January is the coldest month in most cities.
| City | Dec high / low | Jan high / low | Feb high / low |
|---|---|---|---|
| Sapporo | 2.0°C / -4.0°C | -0.4°C / -6.4°C | 0.4°C / -6.2°C |
| Nagano | 6.9°C / -1.5°C | 3.8°C / -3.9°C | 5.3°C / -3.7°C |
| Tokyo | 12.0°C / 3.8°C | 9.8°C / 1.2°C | 10.9°C / 2.1°C |
| Kyoto | 11.6°C / 3.5°C | 9.1°C / 1.5°C | 10.0°C / 1.6°C |
| Osaka | 12.3°C / 5.3°C | 9.7°C / 3.0°C | 10.5°C / 3.2°C |
| Fukuoka | 12.6°C / 5.8°C | 10.2°C / 3.9°C | 11.6°C / 4.4°C |
| Naha (Okinawa) | 21.5°C / 16.8°C | 19.8°C / 14.9°C | 20.2°C / 15.1°C |

2. The Golden Rule: Layers
Japanese trains, shops, museums and restaurants are well heated. If you wear one thick jumper under a heavy coat, you will be too hot indoors and too cold when you take the coat off. Instead, build your outfit in three layers.
Thin thermal underwear. Thin enough to wear all day, indoors and out.
A sweater, fleece or light down vest that you can take off easily.
A warm coat. For Tokyo and Kyoto, a mid-weight coat is usually enough. For Hokkaido, bring proper down.
3. What to Wear, Region by Region
Tokyo, Osaka, Kyoto, Hiroshima, Fukuoka
Days are often sunny and dry. A warm coat, a sweater, a scarf and light gloves cover most days. Snow is rare in Tokyo and Osaka. Rain is less common than in other seasons, but a compact umbrella is still useful.
Hokkaido, Tohoku and the Japan Alps
This is real winter. You need a down jacket, thermal top and leggings, a warm hat that covers your ears, a neck warmer, insulated gloves and waterproof boots. If you are skiing or going to the snow monkeys, add waterproof trousers.
Okinawa
Mild and often windy. A light jacket and long sleeves are enough. Most people find the sea too cold for swimming.
4. Shoes for Snow and Ice
Footwear is the most important item for a trip to snowy areas, and the one travellers most often get wrong.
Choose boots with deep, rubber treads. Smooth soles and fashion boots are dangerous on packed snow.
Sapporo's official tourism site notes that anti-slip spikes that attach to your soles are sold at most convenience stores there.
You will take your shoes off at temples, ryokan and some restaurants. Laces that take five minutes to undo are a pain.
On icy pavements, take short steps and keep your weight over your front foot. Be especially careful at pedestrian crossings and building entrances, where snow is polished smooth by foot traffic.
5. Small Items That Make a Big Difference
- Kairo (カイロ): Disposable heat packs, sold at every convenience store and drugstore. Some stick onto clothing. Do not stick them directly onto your skin, and do not use them while sleeping.
- Lip balm and moisturiser: Winter air in Japan is very dry, especially indoors with the heating on.
- Touchscreen gloves: You will use your phone constantly for maps and train times.
- A small daypack or tote: Somewhere to put your scarf, hat and middle layer when you go inside.
- Thick socks: For temples, ryokan and tatami rooms.
Many of these are easy to pick up at a drugstore or convenience store. See our drugstore guide and convenience store guide.
6. Staying Warm Indoors
Hotels and modern buildings are heated, but traditional houses and some ryokan can be cooler. Look out for the kotatsu (こたつ), a low table with a heater underneath and a quilt over the top, which you may find in ryokan or rental homes. Soaking in a hot spring is the classic way Japanese people warm up in winter. See our onsen guide.
7. A Winter Packing Checklist
- Warm coat (down for Hokkaido and mountains)
- 2 to 3 thermal tops and leggings
- Sweaters or fleeces for the middle layer
- Scarf or neck warmer, hat, gloves
- Waterproof shoes or boots with good grip
- Thick socks
- Lip balm and moisturiser
- A day bag for layers you take off

Conclusion
Dressing for a Japanese winter is about matching your clothes to the region and being able to adjust them as you move between cold streets and warm buildings. Pack thin layers, a warm coat, thick socks and shoes with grip, and buy heat packs and extra thermals locally. Then you will be comfortable from the illuminations of Tokyo to the snow of Sapporo.
