Hello everyone.
Today, I would like to introduce a convenient item "Hokairo (ホッカイロ)" that is useful in winter!
"Hokairo (ホッカイロ)" is now popular in countries other than Japan. Did you know that items were actually born in Japan? I will introduce the history and trivia!

What is a "Hokairo "?
Originally, it was an item for warming hands and stomach by putting warm stones in a cloth bag. The current "Hokkairo" is a bag containing iron sand inside. The first one sold in 1975. Most of them are disposable, and the effect is often about 10 hours. When it comes in contact with air, the iron sand inside oxidizes, and the heat generated by the chemical reaction is used to warm the bag itself. On average, the temperature rises to about 50 ° C for the type that you carry with you, and about 53 ° C for the type that you use by sticking it on your clothes. Nowadays, some shoes are put in shoes to warm the toes. The price varies depending on the size and purpose, but it is about ¥ 300- ¥ 600 for 30 pieces.

| Hand-held type Hokkairo |
Originally developed with reference to "a certain item" in the United States!
The item is a "foot warmer". It was developed by a Japanese company with reference to the foot warmer used by the US Army. The name at that time was "Hokaron". By the way, some are still sold under the name "Hokaron".

Insanely convenient when it's cold! But be careful!
Hokkairo is a big success at work and events on cold days! However, if you use it incorrectly, you may get burned or injured, so be careful! I will explain about that.
1. Do not keep hitting the same place on your body for a long time!
As mentioned above, the temperature of disposable Hokkairo is about 50 ° C, but the temperature rises to about 63 ° C at the maximum. Therefore, if you keep applying it to the same area for a long time, you may get "low temperature burns". For the type that sticks to clothes, avoid sticking the stretched place to the same part for a long time. Also, please be careful as it is dangerous to leave it in your pocket if you use it in your hand.
2. Do not use when sleeping!
The reason is the same as explained in "1.". However, there are quite a lot of people who get low temperature burns when sleeping, so I will write it again. This is because many people take a nap with their Hokkairo on their clothes or in their pockets. When you wake up, your skin may irritate. When taking a nap, keep the Hokkairo away from the sleeping position. Don't use it because it's cold when you go to bed at night!
3. It is miserable when the bag is torn.
As I wrote in the explanation, the contents of the iron sand are mainly "iron sand". If you touch the contents, there is no adverse effect on the human body. It is dangerous to get it in your eyes or swallow it, so be careful. Basically, the contents of the Hokkairo sold in Japan will not come out unless it is intentionally broken. However, if the contents come out ... Imagine the iron sand scattered on the floor of the room. What if there was a PC or smartphone nearby? What if it gets scattered near furniture with magnetic force? Be careful as it can be very annoying.
It has been exported outside Japan since 2012, and the largest exporters are foreign countries in Asia.
It seems that it is sold under the name of "disposable hand warmer" in New York. It seems that there is not much distribution in European countries. If you want to use it, please come to Japan! Also, in Russia, it seems to be popular with traffic police officers, especially the type of Hokkairo that is used by putting it in shoes seems to be selling! Hokkairo will be a strong ally in extremely cold regions.
That's all for this article.
How was everyone? Did you know Hokkairo?
If you want to use it, please come to Japan.
It is a very nice item that warms your body on a cold day.
Oh, but be careful when you can buy it as a souvenir.
It seems that customs in countries other than Japan may mistake it for illegal drug powder. lol
At that time, try using this article and actually in front of the first one.
see you later then!
