Preparing for a stay with a shared bath
You are looking forward to the hot spring, and slightly nervous about the bathing part.
Hotels, ryokan and rooms
Hotel heating and cold rooms in winter
You are used to warm nights, and a chilly hotel room is a real worry.
Most Japanese hotel rooms are heated and comfortable, but the building around the room can be cold. Plan for chilly corridors, drafty windows and cold bath areas, and ask about heating before you book.
This guide is for travellers from hot climates who have never slept in a cold room.
Why can a Japanese room feel cold?
The Japan National Tourism Organization (JNTO) notes that Japanese buildings are often not well insulated and central heating is rare 1. A room can be warm while the corridor, lobby or older wing stays cold.
Winter outside is a bigger jump for you. Tokyo averages 5.4 °C in January and Sapporo averages -3.2 °C, according to the Japan Meteorological Agency 2.
Which stays tend to be warmer?
Modern business and city hotels usually have an in-room heater or air conditioner that you control. Hotels with an onsen, a hot spring bath, add a long hot soak before bed.
Older ryokan, with sliding paper doors and tatami floors, can feel cooler at night. Our ryokan sleeping guide for elders explains the bedding.
What should you check before booking?
Ask these questions:
- What heating does the room have, and can I control it?
- How cold are the corridors and the bath area?
- Can you add an extra blanket or heater?
- Is the room near the lift, away from drafty stairs?
- Is the bath tub deep enough for a soak?
Put elders or young children first when you ask. A short message to the hotel works better than a long one.
How do you stay warm in the room?
Set the heater when you arrive, not at bedtime. Soak in the bath, since most hotel bathrooms have a deep tub 3. Keep a kairo, a small heat pad sold in convenience stores, in socks or pockets 3.
Sleep in thermal innerwear and keep slippers by the bed. The cold-weather packing guide lists what to bring.
When should you choose another stay?
If anyone in your group struggles with cold, choose a modern hotel near a station over a remote old inn. The onsen-ready stay checklist and the Hokkaido winter stay guide cover other winter choices.
If winter nights are your main worry, send us your dates and who is travelling, with any elders or small children. We reply with room types that keep the cold manageable and the questions to confirm.
Keep planning
Tatami rooms and futons for elders
Your parents want the ryokan night, and you worry about getting up off the floor.
Cold-weather packing for tropical travellers
You have never needed a coat, and a Japanese winter is coming.
Hokkaido winter stays and icy walking
You are used to warm pavements, and you worry about dragging luggage over ice.
Winter coats and luggage allowance
Your coat is bulky, your suitcase is limited, and you have never packed for real cold.
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.
Questions travellers ask
Are Japanese hotel rooms warm in winter?
Most modern hotel rooms have an in-room heater or air conditioner that you control, so the room itself is usually comfortable. JNTO notes that Japanese buildings are often poorly insulated and central heating is rare, so corridors, lobbies and older buildings can feel cold.
Are ryokan colder than hotels?
Older ryokan can be, because of thin walls, sliding doors and cold corridors. Many keep rooms warm with heaters and futon, but check the heating type and ask for an extra blanket. Hotels with onsen can be a warmer choice for elders.
What can I do if my room is cold?
Ask the front desk for an extra blanket or a second heater, set the room heater early, and soak in the bath before bed. A kairo warmer tucked into socks helps overnight. Keep thermal innerwear packed for sleeping.
What should I ask before booking in winter?
Ask what heating the room has, whether you control it, and how cold the corridor and bath area get. Mention elders or young children. The answer helps us choose a room that suits tropical travellers.
