Heating Your Apartment
Japanese apartments are notoriously poorly insulated. Single-pane windows and thin walls make winters tough.
Main Heating Options
エアコン (Air conditioner — heat mode)
- Most apartments have one; cheapest to run
- Set to 20–22°C; use timer at night
石油ファンヒーター (Kerosene fan heater)
- Very common in Japan, especially in colder regions
- Cheap to run; heats a room fast
- Requires kerosene (touyu) from gas stations or home centers
- Not suitable for rooms without ventilation — open windows slightly
コタツ (Kotatsu)
- Low table with a heating element underneath, covered by a blanket
- Classic Japanese way to stay warm — energy efficient and cozy
- Buy at Nitori or second-hand shops from ¥5,000
Electric carpet / panel heater
- Good supplemental heat; safe for overnight use
What Doesn’t Work Well
- Central heating — most Japanese homes don’t have it
- Heated floors (床暖房) — available in newer apartments; check before signing lease
Staying Warm: What Japanese People Use
Heat-Tech (ヒートテック)
Uniqlo’s heat-retaining inner layer is a staple for everyone in Japan. Layer under your clothes.
- Heattech top + bottom: ¥1,500–2,000 each
- Extra Warm and Ultra Warm versions for colder climates
Hand Warmers (カイロ)
Disposable stick-on warmers are everywhere — convenience stores, ¥100 shops.
- Standard hand warmer: ¥100 for 10 packets
- Stick-on (貼るカイロ) for back/waist — use during outdoor activities
Other Essentials
- ネックウォーマー (neck warmer) — better than a scarf in public transport
- 電気毛布 (electric blanket) — run before bed, turn off while sleeping
- 足湯 (foot bath) — small electric foot baths from ¥3,000 at home centers
Snow Regions: Practical Tips
If you live in or visit a heavy-snow region (Niigata, Hokkaido, Nagano):
Getting Around
- Snow tires required — if you drive, swap by November
- Carry a snow brush and ice scraper in your car
- Studded tires banned — use studless snow tires
- JR trains run with surprising reliability — even in heavy snow
Walking in Snow
- Slip-resistant shoes — buy anti-slip covers (滑り止め) from ¥500
- Watch for icicles — falling ice from buildings is a real danger; avoid walking under eaves
- Cities like Sapporo use underground heating on main streets — find these routes
Home Preparation
- Clear snow from car before driving (legally required in some prefectures)
- Roof snow — old wooden houses may need snow removal; hire professionals
Winter Events and Activities
- 冬花火 (Winter fireworks) — major fireworks festivals in Nagano and Niigata
- 雪まつり (Yuki matsuri) — Sapporo Snow Festival (February) — world-class snow sculptures
- スキー / スノーボード — Niseko, Hakuba, Nozawa Onsen are world-class ski resorts
- Onsen — perfect in winter; snow onsen (雪見風呂) is one of Japan’s best experiences
- Illuminations — cities and theme parks covered in lights December–February
Winter Food and Drinks
- 鍋料理 (Nabe) — Japanese hot pot, the ultimate winter comfort food
- 甘酒 (Amazake) — warm sweet rice drink, sold at shrines

December is busy with:
- お歳暮 (Oseibo) — year-end gift giving to bosses and mentors
- 大掃除 (Osoji) — major home cleaning before New Year
