If you feel colder than expected while traveling in Japan, you’re not alone.
Japanese winters are not only cold in temperature, but also come with chilly winds and damp air, which can make sightseeing uncomfortable—especially if you are walking a lot.
That’s when Japanese disposable heat packs, known as “Kairo,” become incredibly helpful.
Where to Buy Heat Packs in Japan
Disposable heat packs are widely available during winter in Japan.
You can easily buy them at:
- Convenience stores (7-Eleven, FamilyMart, Lawson)
- Supermarkets
- Drugstores / pharmacies
They are inexpensive, usually costing only a few hundred yen, and are perfect for travelers who suddenly feel cold while sightseeing.
Two Types of Heat Packs in Japan
There are mainly two types of disposable heat packs.
Non-adhesive (Hand warmers)
- Held in your hand or placed in a pocket
- Easy to use for short outdoor activities
- Can be taken out whenever needed
However, they only keep you warm while you are holding them, so the warmth is limited.
Adhesive heat packs (Highly recommended)
The most recommended option for travelers is the adhesive heat pack.
The best way to use it is to stick it on your back, inside your clothing.
Why sticking it on your back works best
- Gently warms your entire body
- Keeps your hands free
- Does not interfere with sightseeing
- Comfortable even during long walks
Because the back is close to your body’s core, warming this area helps maintain overall body temperature.
Most adhesive heat packs last for about 12 hours, making them perfect for all-day sightseeing from morning to night.
Perfect for Sightseeing in Winter
Adhesive heat packs are placed under your clothes, so:
- They are invisible from the outside
- They do not add extra luggage
- You don’t have to worry about dropping them
They are ideal for walking tours, visiting temples and shrines, or enjoying night views during winter in Japan.
Why Japanese Heat Packs Are So Comfortable
Japanese heat packs are designed for daily use and are known for:
- Stable and gentle heat
- Long-lasting warmth
- Reliable temperature control
In many countries, heat packs are mainly outdoor or emergency items.
In Japan, they have evolved into everyday winter essentials, made for comfort, safety, and convenience.
Important Safety Tips
Important: Do not stick heat packs directly onto your skin.
Always place them over underwear or clothing to avoid low-temperature burns.
If you have sensitive skin or feel discomfort, stop using the product immediately.
Summary: Stay Warm While Traveling in Japan
If you feel cold while traveling in Japan:
- Buy disposable heat packs at convenience stores, supermarkets, or drugstores
- Choose adhesive types if available
- Stick one on your back for the best warmth
- Follow safety instructions carefully
This simple tip can make your winter trip in Japan much more comfortable and enjoyable.
