Keeping Warm in the Winter, Japan-Style

3 Japanese tanuki statues covered in snowPoor tanuki: they must be freezing their balls off.

Now that Halloween is all over and done with, it’s time to look ahead at the upcoming cold months. To quote Game of Thrones, winter is coming.

And winter in Japan, especially in the northern parts of Japan, can be unforgiving. Not only are winters cold and snowy, but in lots of buildings Japan there’s very little insulation to protect you from the ravages of winter. Fortunately, there are lots of awesome, uniquely Japanese ways to stay warm and toasty in the frigid winter months!

Japanese homes don’t usually have central heating or cooling, they have little insulation, and double-paned windows that keep the cold out and the heat in are regrettably rare. This is because lots of places in Japan have traditionally been designed to be breezy in the summer, and central heating and cooling is pretty expensive.

There are other theories why Japanese homes are so poorly insulated – that they’re built cheaply to prepare for the inevitable destruction of earthquakes, that they’re poorly built to save big construction companies money – but those are kind of fringe theories.

But regardless of why some Japanese homes are so cold, people have found ways around it. Let’s take a look at the coolest ways to say warm in the Japanese winter:

Kotatsu

No post about winter in Japan is complete without talking about kotatsu. The idea behind kotatsu is both simple and brilliant: it’s a low table with a blanket around the edges and a heater strapped beneath it.The blanket keeps all the heat trapped underneath the table to warm up cold legs.

It’s the greatest idea since eating Cheetos with chopsticks.

KotatsuLooks cozy!

Kotatsu are a great way to keep warm, and forcibly gather the family together in one place. Nothing says “family time” like huddling together for warmth. People even take naps under them, and kotatsu become pretty much become permanent spots for household pets, as exhibited by YouTube superstar Maru:

Kotatsu are less popular in the northern regions of Japan, where it’s important to keep the entire room, apartment, or house warmed up so that water pipes don’t freeze and burst. But on the main island of Honshu, kotatsu are plentiful.

Space Heaters EVERYWHERE

Since many Japanese households don’t have central heating because of the cost, lots of people rely on smaller space heaters to heat rooms individually. Some households practically have a space heater for every room in the house, but most have at least one for the main living area.

There are lots of different kinds of heaters that people in Japan use; everything from kerosene and oil to regular ol’ electric heaters.

And, once again, your cat or dog will probably use your heater more than you will. How do the animals get all the breaks?

Haramaki

Haramaki originally referred to the armor a samurai would wear around his waist, but that’s so 16th century. Nowadays, haramaki refers to something a little bit different.

Today, a haramaki is a knit cloth garment that you wrap around your stomach to keep your core warm.

Usually Japanese people associate haramakis with children and old people, but haramaki makers have been trying to make it seem a lot more trendy and fashionable. They’ve also been trying to show – scientifically – that haramaki make you a lot warmer, too.

Science!

People who sell haramakis also say that they “promote wellness” as well, doing things like keeping a baby warm during pregnancy, accelerating the processing of alcohol by the liver, and relieving menstrual cramps.

The Japanese love to talk about how important a warm stomach is to staying well.

Whether or not these claims have any basis in science is a little questionable, but that doesn’t stop a haramaki from keeping you toasty.

Hot Water Bottles

Hot water bottles: also available in mini sizes.

Back in the day, obaasan and ojiisan used to have to cultivate trees, cut them down, turn them into charcoal, heat water, pour it into a giant metal hot water bottle, and scald their feet while they slept in order to keep warm. Okay, not really, but hot water bottles have been around for a while, and they used to be a bit more of a hassle.

Nowadays though, hot water bottles are a great way to keep toasty while you sleep. They’re much smaller, cuter, and more manageable than the clunky metal hot water bottles from back in the day. People even accessorize their hot water bottles with covers and the like.

Pff. Kids these days.

Don’t Die

A skull engraved on a tombstone

No, seriously; don’t die. While all of these ways of keeping toasty in wintertime look awesome, they can be deadly too.

According to Japan Probe, something like 20 people die every year in Japan from space heaters when they throw things (clothes, blankets) on top of them and forget about it. Not only that but with kerosene-powered heaters you have to keep a can of kerosene around to refill the heater, which can spill and catch fire and burn your whole house down.

And of course, kotatsu are basically designed to be the biggest fire hazard ever. Who thought “Hey let’s design a heater that’s completely covered at all times?” Dangerous enough to warrant a government warning? You decide.

Don’t even get me started on hot water bottles. All I can say is that most of my family is gone from this world because of it.

Okay, I might be exaggerating a little bit about the dangers of these things. But you should probably nonetheless be careful when using them.

    Another great article from Hashi!! First comment woo!!

    God I love kotatsu. Best idea ever

  • http://twitter.com/MissJenn610 Nihonjenn

    I live in Hokkaido and life would be incomplete without kotatsu. Also, the hyakuen shop has all those wonderful stick on heating pads. Heavenly! :) Fun article… though I’m not quite ready for winter yet… :P

  • http://valerauko.net Vale

    And of course no buildings are insulated. At all.

  • Ollie Capehorn

    Why no mention of ユニクロ HeatTech products? They sell out every year as they’re hugely popular – almost a winter staple in Japan.  

  • Calobrin

    Whenever I get cold around the winter months, I usually have a decent sized space heater next to my desk at my computer. (It is where I spend most of my time) but the thing is I don’t leave it on for extended periods of time due to it being a hazard. or it blowing a fuse, whichever comes first.

    Of course being in America I don’t have the problem with insulation to a degree. I live in the basement, a well furnished basement but a basement none the less.

    Great article! This gets me warm just thinking about it :D

  • JD

    Great article, but god I hate using all of these products (coming from a land with central heating and properly insulated buildings). I wonder how much it’d cost to build a house that conforms to both British and Japanese regulatory standards (if that’s even possible!).

    I can’t be the only one that finds kotatsu uncomfortable to use, but you mentioned an added disadvantage: family time! hehehe

    Somebody in the comments mentioned Uniqlo Heat Tech products, which are awesome. They work tremendously well, and have only one downside: when you get to school/work/etc. some annoying individual has to turn the heating all the way up to 30 celsius (86F) because they’re underdressed for the winter…

    I really love haramaki. I’ve even got one that has a little pouch for putting in a small heat pad/hand warmer thingy. Pretty spiffy, though the feeling of it takes some getting used to.

  • http://www.tofugu.com/ Hashi

    Well, they do have *some* insulation, but it sure doesn’t feel like it!

    From what I can tell, Japanese building standards are getting better over time.

    You’re right, I probably should’ve HeatTech stuff, I guess I was thinking of more traditional stuff.

  • :3

    I wish that I had a kotatsu — it’d be the perfect place to internets in the winter. Anyone know where I could get one reasonably priced in the states? (lol)

  • Moose

    Sooo, I’m a poor college student living in Wisconsin and I have to say, I should make my own Haramaki to wear in the winter.  Things I usually do when it’s cold:
    1. keeping a warm drink nearby, even if it means I’m just going to hold the cut to keep my hands warm
    2. lots of warm toasty knee-high or thigh-high socks.
    3. I don’t trust hot water bottles, so I have a sock stuffed with rice that I put in the microwave.

    As someone who lives in the mountains(the cold months started like 3 weeks ago, though it’s still sunny most days I don’t think the snow is going to melt) I have to say if the CENTER part of me is cold I really need to put on more clothes. Gloves hats and cozy socks are where it’s at. Though the haramaki probably WOULD be good for menstrual cramps. They should make battery heated ones or something.

  • http://www.tofugu.com/ Hashi

    I know that the Asian market near me lets you mail-order kotatsu through them, but I don’t know how expensive it is. Still, might be worth checking out!

  • http://www.tofugu.com/ Hashi

    Out of curiosity, why don’t you trust hot water bottles?

  • Hailey

    I am not looking forward to the winters when I go and study abroad for a year. I’m such a pansy when it comes to cold. I hope no one in Japan minds if I just nap under the kotatsu the entire time!!!

  • Kellylav143

    The haramaki are cute! I’m in New England and I always wear layers during the winter, and wearing a haramaki and leg warmers would be a great way to retain more freedom of movement! (wearing pj pants under your jeans and 3 shirts is pretty constricting) =)

    Yes. I am a mutant superhuman who is immune to cold. But that’s just as far as my super powers go. When it’s hot on the other hand…

    Seems to me that the Japanese are a pretty pessimistic people, trying to save money by building cheap buildings for inevitable earthquakes. Are they cheap??? I live in California within 50 miles of San Francisco and we get 4.0s every year and the next major earthquake is 5 years overdue but no one is freaking out cuz we’re used to it. Everyone spends SO MUCH FREAKIN MONEY on building reinforcement, plywood, pretensioning, etc here, I bet my 2 cents that less than 100 buildings will come down in a 9.0.

  • キツネじゃない

    But aren’t those fringe theories kinda fringy?

  • キツネじゃない

    Aha, but if I sort by the newest comment, then your’s will be eternally at the bottom! Dramatic irony, that!

    It’s because the walls are holograms. If they turn off, the “house” is revealed to be nothing more than some furniture on a plot of land.

  • Ternasha

    My teacher made a kotatsu for our Japanese class.
    They are indeed cozy to nap under… xD

    I’ve got a rant on space heaters here: http://hanlonsrzr.blogspot.com/2011/01/theyre-called-space-heaters-for-reason.html

    This crap they call housing wouldn’t keep you alive in my Canada in autumn!

  • Foozlesprite

    It might actually be cheaper to nail a king-sized comforter to a table with sawed-off legs and stick a space heater under it than to buy a kotatsu.  Can’t find a decent price on one in the states as they all have to be imported, and shipping on that can cost an arm and a leg.

  • キツネじゃない

    Are you using the alt + shift shortcut to change languages? That worked for me.

  • Matthew Stiltner

    I actually considered buying a Kotatsu when I moved into my new place, but the whole “this may catch a flame and destroy all my belongings” thought crept into my mind all too much. I wonder if it is common to hear about fires caused by Kotatsus in Japan?

    One more very important item for winter is a heated toilet seat. 
    When I lived in the dorm at the start of my arrival to Tokyo, toilet was probably the only warm place at home thanks to this invention.

    I’ve actually found that living in Japan, my winters are much warmer because of the methods that Japan uses to heat. I grew up in Upstate NY in a quite drafty house with radiators in every room which didn’t work well. My school likes its teachers to not freeze, so we have double paned windows and insulation. In addition, the toyu heater keeps my room warm and heats up my room in the time it takes to take a shower. Winter in Japan can be nice and toasty, you’ve just gotta know what to do and how to get your hands on insulation.

  • http://pulse.yahoo.com/_NMMV6AXYY4MPQ67ULYXG542TKA Jen

    I actually prefer the Japanese method of heating. I grew up in a drafty Victorian house in Upstate NY with radiators that you had to touch to feel the heat. Here I just push a button and my room is up to 18 in ten minutes. Perhaps it’s because I’ve found the mythical “double-paned windows and insulation,” maybe it’s because I can close the doors. Regardless, I like it much more here, and I live in the Northern Japanese Alps.

    I am just about impervious to the cold except when I sleep, so for that, I have a water bed (it’s for my back, don’t judge). There is nothing like climbing into a warm bed after a long day (or short, since it is winter and all).
    Also, a nice mug of hot chocolate or tea does a lot of good as well. By the way, am I one of the only Americans that makes their own tea by hand (as in; getting loose tea leaves, steeping them, and straining them for each mug)?

    I live on the coast of South Carolina, though, so it doesn’t get ‘cold’ like it does for a lot of y’all. Even though the thermostat doesn’t usually drop below fifteen degrees(F) the humidity makes it feel much colder… and hurts your joints, yay for that heated water bed!
