January in Niseko averages -5.4°C and Furano dips to -14°C at night. How to layer, which gloves and socks work, and plugs (Type A, 100 V).
Japan's ski towns are cold but not extreme: in January, Kutchan (the town below Niseko) averages -5.4°C with nightly lows around -10°C, Furano drops to about -14°C overnight, and Hakuba in Nagano averages -2.8°C. If you have never been in snow, pack three thin layers instead of one heavy coat, waterproof gloves and outerwear, wool socks, sunglasses or goggles, and a strong moisturizer. Japan uses Type A plugs at 100 V, so bring an adapter if your home plugs are different.

The top of a ski lift is several hundred metres higher than the town and usually colder, and wind on a chairlift makes it feel colder again. In Hokkaido, expect it to feel well below -10°C at the top on a windy January day. If you also visit Tokyo, a normal winter coat is enough there. Our best time to ski in Japan guide has month-by-month temperatures.
Use three layers that you can add or remove during the day.
One heavy city coat is a poor choice: it is not waterproof, it is too hot when you walk uphill in boots, and you cannot take part of it off.
If you will ski only once or twice in your life, rent the jacket and pants. Most large rental shops in the ski towns rent clothing as well as skis. At Spicy in Hakuba, for example, a jacket and pants cost ¥6,600 for one adult day in 2026-27 (Spicy Rentals). Bring or buy your own base layers, socks and gloves, which shops do not rent. Our rental guide compares shops, and the packing checklist lists everything by budget.
Waterproof boots with grip, a warm waterproof jacket, gloves and a hat. If you plan to play in the snow at a resort, waterproof pants as well. See snow play parks for non-skiers.
