How to stay warm in winter…Japanese style

The day before yesterday, it was snowing in many parts of Japan…including Tokyo.

(That day (February 11th) was also a holiday in Japan, so we didn’t have to go to work or school in the snow.)

Does it snow in the winter where you live?

It normally snows one or two days each winter in Tokyo. And not a lot of snow. The snow that fell here Friday melted later in the day.
(It does snow much heavier in northern Japan, though.)

How do you stay warm in the winter where you live?
Do you heat your entire house with electric central heating? It’s a waste to heat the whole house all day…especially parts of the house that are unoccupied.

In Japan we stay warm in winter a bit differently.

First of all, rather than heating unused rooms of the house with central heating, homes here use either an electric wall-unit air-conditioner / heater or a gas heater and warm only rooms with people in them.

Japanese wall-unit A-C / heater is high-tech with a timer and remote-control.

The same gas room heater that we have.

The heater isn’t on all day and night. Once the room is warm enough, it’s turned off. Saves money.

But this isn’t the only technique used here.
We also use:

Heated carpet

炬燵　(A "kotatsu") traditional Japanese table with a heater under it to keep you warm in winter and a blanket to keep it's heat in.

"Hanten" winter room coat

湯たんぽ (Hot-water bottle)

Also, bathtubs in Japan are separate from the shower and they have a thermostat that keeps the water warm…so, unlike bathtubs in America, Japanese baths are used daily—especially in the winter.

Outside the house, during the cold months in Japan you can buy hot canned coffee, tea and other drinks from vending machines.

And many people carry　「ホカロン」 (charcoal hand-warmers).

Does your country have any useful techniques like these to stay warm during the winter?
