Hi! I’m Sensei.
“Winter (Fuyu / 冬) in Japan is too cold to sleep!”
“I left the Air Conditioner (Air-con / エアコン) on and my electricity bill went over 10,000 yen…”
For everyone coming from Southeast Asia, the cold in Japan can be really tough.
However, if you blast the AC, the electricity bill for your dorm will get expensive, and you might end up fighting with your roommates.
In times like these, let’s use Japanese wisdom: the “Electric Blanket (Denki Mofu / 電気毛布)”.
With this, you’ll stay warm until morning even if you turn off the AC, and your electricity bill will be cheap!
Why is the Air Conditioner not the best option?
The AC uses a lot of electricity because it warms the entire room.
But when you sleep, you only really need to warm the “inside of your futon,” right?
| Type of Heater | Electricity cost per hour | 1 Month (8 hours/day) |
|---|---|---|
| Air Conditioner (Air-con / エアコン) |
Approx. 20 – 50 yen | Approx. 5,000 yen+ Expensive! (Takai / 高い) |
| Electric Blanket (Denki Mofu / 電気毛布) |
Approx. 1 yen | Approx. 240 yen So cheap! (Yasui / 安い) |
- Just lay it under your futon and it’s as warm as heaven.
- If it gets dirty, you can remove the cord and wash it in a washing machine (Sentakuki / 洗濯機).
- The price is low (you can buy one for around 3,000 yen).
Recommended ones you can buy on Amazon!
I’ll introduce some cheap and durable Japanese manufacturers that sell well on Amazon Japan.
I recommend companies like “Sugiyama (スギヤマ)” or “Yamazen (ヤマゼン)”.

A bestseller that Sensei also uses.
If you turn it on 30 minutes before bed, you’ll feel pure bliss the moment you get under the covers.
- Size: 140cm × 80cm (Perfect for a single bed)

Summary: Don’t catch a cold!
If you get sick in Japan and go to the Hospital (Byoin / 病院), it will cost a lot of money.
Buying a 3,000 yen electric blanket is also an “investment in your health.”
Use the money you saved on electricity to eat something delicious.
And if you want to use your smartphone cheaply outside, don’t forget to review your SIM card plan too!
