Winter in Japan offers an enchanting mix of snowy landscapes, steamy hot springs, and cozy cultural experiences. Whether you’re heading north to Hokkaido’s powder snow, exploring Kyoto’s quiet temples dusted with frost, or strolling through Tokyo’s glittering winter illuminations, each region offers a different side of the season. Packing wisely will make all the difference in keeping you warm, comfortable, and ready to enjoy it all. Below is a guide on what to bring for your winter trip to Japan.
Travel Essentials
Layered Clothing
Japan’s winter temperatures vary greatly depending on where you go. In Hokkaido and northern Honshu (like Aomori or Akita), temperatures can drop well below freezing, while Tokyo and Osaka remain milder, usually between 2°C and 10°C. Okinawa, on the other hand, rarely gets cold at all. Pack thermal base layers, sweaters or fleece, and a waterproof, insulated jacket. Layering allows you to adjust easily as you move between the outdoor chill and heated indoor spaces.
Winter Accessories
Winter in Japan can range from mildly chilly in the south to bitterly cold in the north, so the right accessories can make all the difference. Start with a warm hat, gloves, and a scarf, essential items to protect against the wind, especially when sightseeing outdoors or walking between train stations. For snowy regions like Hokkaido or Nagano, choose waterproof gloves and insulated wool socks to keep your hands and feet dry and warm throughout the day. A neck warmer or thermal gaiter is also useful, as it can easily double as a face covering when the temperature drops sharply.
If you’re planning to spend time outdoors (skiing, visiting snow festivals, or exploring mountain villages like Shirakawa), consider wearing ear muffs or heat-retaining headbands, which are compact yet very effective in windy areas. Touchscreen gloves are another great addition, allowing you to take photos or use your phone without exposing your hands to the cold.

Kairo (Japanese Heat Packs)
During Japan’s winter, one of the most popular ways to stay warm is by using kairo (カイロ), small disposable heat packs that generate warmth through a natural oxidation process. Inside each pack is a blend of iron powder, salt, water, and activated charcoal that reacts with oxygen when opened, producing gentle, consistent heat for up to 8-12 hours. There are two main types: stick-on kairo, which you can stick to clothing (never directly to skin) around your back or abdomen for body warmth, and pocket kairo, which are ideal for keeping hands warm inside gloves or coat pockets. You can find them everywhere in winter, at convenience stores, drugstores, supermarkets, and even vending machines. Prices usually range from 100 to 300 yen for multipacks, making them an affordable and practical must-have for any winter traveler in Japan.
Footwear
A reliable pair of waterproof boots with a solid grip is essential for safely walking on snowy or icy paths, particularly in the northern areas or when exploring hot spring towns such as Hakone or Noboribetsu. In urban destinations, insulated sneakers or shoes with warm lining are typically sufficient, though keep in mind that you’ll often need to take them off when entering temples or traditional ryokan inns. So wear a pair of warm socks underneath!
Compact Umbrella or Rainproof Jacket
Although winter in most regions is relatively dry, snow can melt into slush or turn into light rain, particularly in central Japan. A small, foldable umbrella or lightweight rainproof jacket will come in handy.
Moisturizers and Lip Balm
Cold winds and indoor heating can be harsh on your skin. Bring your preferred moisturizer, lip balm, and hand cream; while Japanese drugstores sell a great selection, your favorite brands may not be available.
Medicine and Cold Remedies
If you tend to catch colds easily, pack your usual medicine. While Japan’s pharmacies carry reliable brands, product names and dosages can differ, and it’s often more convenient to have what you’re used to.
Plug Adapter and Power Bank
Japan uses Type A plugs (the same as in the U.S.) with 100V voltage. Most modern devices will work fine, but Europeans and others may need adapters or converters. Winter days are shorter, and you’ll likely spend more time taking photos of snowy streets and night illuminations, so a power bank is essential.
Cash
Some mountain resorts and rural ryokan still prefer cash payments, especially in regions like Nagano or Tohoku. Keep some yen on hand for small shops, local transport, and vending machines near ski areas.
A Compact Humidifier
Many Japanese hotels (especially business hotels) have dry indoor air. Small USB or bottle humidifiers help keep your throat and skin from drying out. They’re cheap and easy to find at electronics shops like Bic Camera or Yodobashi.
Bath Essentials for Onsen Visits
If your winter plans include visiting an onsen (hot spring), bring a small towel and toiletries you prefer, though most facilities provide basics. Avoid wearing jewelry in hot springs, as minerals in the water can cause discoloration.

Snacks for the Road
Travelling in winter often means long train rides or bus trips between regions. Japanese convenience stores offer a wide range of seasonal treats, try yaki-imo (roasted sweet potato) or anman (steamed buns filled with red bean paste). These warm, easy snacks are perfect to keep your energy up during travel days.

HeatTech Clothing: Your Secret Weapon Against the Cold
If there’s one winter essential you’ll see everywhere in Japan, it’s UNIQLO’s HEATTECH, a revolutionary fabric technology designed to keep you warm without bulk.
HEATTECH was developed in the early 2000s by UNIQLO and Toray Industries, one of Japan’s leading textile companies. The goal was to create a fabric that could generate and retain heat naturally while staying thin, soft, and comfortable.
The material blends rayon, acrylic, polyester, and spandex, which together absorb moisture from your body and convert it into heat through a gentle chemical reaction. The fibers then trap that warmth close to your skin. Some lines also include argan oil for softness and anti-static technology to prevent cling in dry weather.
There are several types of HEATTECH fabrics:
- HEATTECH (Standard): Great for everyday use in Tokyo or Osaka.
- Extra Warm: 1.5× more heat retention, ideal for colder regions like Nagano.
- Ultra Warm: 2× warmer, perfect for Hokkaido’s snow.
You can find HEATTECH items across Japan, from UNIQLO stores in airports and malls to local branches in every city. It’s affordable, packable, and a true Japanese innovation that makes winter travel much more comfortable. If you don’t have access to UNIQLO, brands like GU, Muji, and Airism Warm also produce similar technology-based thermal wear. Outdoor brands like The North Face, Columbia, or Montbell offer high-performance thermals designed for extreme cold or mountain activities.
Regional Overview
- Hokkaido: Pack heavy-duty winter clothing, thermal socks, snow boots, and layers suitable for subzero temperatures. Sunglasses are also useful, as sunlight reflecting off snow can be intense.
- Tokyo and Kansai (Kyoto, Osaka, Nara): You’ll need moderate winter clothing, including warm coats, scarves, and gloves, which should be sufficient. As it rarely snows heavily in these regions, an umbrella is more useful than snow gear.
- Nagano and Tohoku: Prepare for deep snow, especially if skiing or visiting outdoor hot springs. Waterproof boots and insulated pants will make your trip far more comfortable.
Winter in Japan is both serene and festive. From snow-covered shrines to steamy outdoor baths surrounded by mountains, this season offers unforgettable sights. With the right packing list, you’ll be ready to embrace Japan’s winter charm, no matter which region you explore.
