Hotel heating and cold rooms in winter
You are used to warm nights, and a chilly hotel room is a real worry.
Preparing from Malaysia
Cold-weather packing for tropical travellers
You have never needed a coat, and a Japanese winter is coming.
Pack in layers, not in one big coat. Wear a thermal base layer, a warm middle layer and a windproof outer layer, and keep each piece easy to take off. This is the best way for a tropical body to stay comfortable between cold streets and warm rooms.
How cold is it, really?
The Japan Meteorological Agency (JMA) gives January mean temperatures of 5.4 °C for Tokyo, 6.2 °C for Osaka and -3.2 °C for Sapporo 1. Winters in Tokyo are cold and dry, with snow rare but possible 2.
Wind and damp make it feel colder than the number. In the mountains, it can be much colder: Murodo on the Alpine Route is about 15 °C lower than at sea level 3.
What does layering mean?
Layering means several thin layers, each doing one job.
- Base layer: thermal underwear, close to the skin.
- Middle layer: fleece, a light sweater or a down vest.
- Outer layer: a windproof, water-resistant coat.
- Extras: gloves, a hat, a scarf and warm socks.
Three layers suit Tokyo and Osaka. Add a fourth, and snow boots, for Sapporo and mountain towns. Our first snow guide shows what a family needs.
Why does indoor heating matter?
Trains, shops and many hotels are heated, so a thick coat feels too hot indoors. That is why layers beat a single heavy coat.
Wear a thin top you are happy to sit in, and carry the coat. Keep a small bag for it. Read heating and cold rooms in Japan for what to expect at hotels and inns.
How do you pack for the suitcase?
Wear your bulkiest layer on the flight, and pack thin items.
- Thermal wear packs small, so bring two sets.
- Pack gloves and a hat in your day bag.
- Leave a quarter of the suitcase empty for souvenirs.
- Choose one coat that works for the whole trip.
If you buy a coat in Japan, send heavy items ahead. Most major hotels can arrange luggage delivery between hotels, with limits of about 160 cm in total size and 25 to 30 kg, and station coin lockers cost 300 to 600 yen 4. See seasonal luggage and winter coats.
What should Malaysian travellers remember?
Try your layers at home in an air-conditioned room first. Children and elders feel the cold sooner, so add a spare layer for each. Choose thermals before a coat, since they help most.
If you are unsure what to pack, send us your cities and dates. We list the layers for your itinerary.

Keep planning
Hokkaido in winter or summer
You are choosing between snow and cool green fields, and want to know what each demands.
How cold is Tokyo versus Hokkaido in winter
You have never felt anything below the air-conditioning, and you want to know what winter means.
Japan with grandparents, fewer bag transfers
You keep picturing a parent on a station staircase, suitcase in hand.
Packing light for a multi-city Japan trip
You are moving between cities, and every extra kilo has to be carried up a station staircase.
Winter coats and luggage allowance
Your coat is bulky, your suitcase is limited, and you have never packed for real cold.
Questions travellers ask
How cold is Japan in January for a Malaysian?
The Japan Meteorological Agency gives January means of 5.4 °C for Tokyo, 6.2 °C for Osaka and -3.2 °C for Sapporo. Tokyo's January mean is far below anything at home. Wind makes it feel colder, so choose windproof layers.
What is layering, and how many layers do I need?
Layering means several thin layers instead of one thick coat. Wear a thermal base layer, a warm middle layer such as fleece, and a windproof outer coat. You add or remove one layer as you move between outdoors and heated rooms. Three layers suit Tokyo and Osaka, and a fourth suits Sapporo.
Will I be too hot indoors?
It can happen. Trains, shops and many hotels are heated, so a thick coat becomes uncomfortable. Layers you can take off and carry solve it. Keep a light bag for the coat, and wear a thin top you can sit in comfortably.
How should I pack a winter coat in my suitcase?
Wear your bulkiest coat on the flight and pack thin layers. Thermal wear packs small. Leave space for souvenirs, and if you add a coat during the trip, send heavy items ahead with luggage forwarding. We help plan this with your hotels.
