Why Do Japanese People Wear Surgical Masks?

For first time visitors to Japan, seeing people out and about in surgical masks can be a bit confusing. Are they germaphobes? Do they have really bad allergies? Do they have some sort of awful incurable disease that requires them to wear a mask to prevent the spread of infection? Oh, God! Should I be wearing one too!?

Okay, so maybe that’s a bit of exaggeration. But for those unfamiliar with the way things are done in Japan, the whole surgical masks being worn in public thing can be kind of strange and unfamiliar. So why do they do it, anyway?

They’re Sick

By far the most common reason people in Japan wear surgical masks out in public is because they’re sick. Chances are it’s not some life threatening, dangerous and debilitating illness – they’re just wearing the mask to be considerate of others and to help contain the spread of germs. Just think about how many people cough or sneeze into their hands and then go on to touch the things we use every day. Door handles, guard rails, the poles and rings you hold onto on the subway. People touch a lot of stuff.

These surgical masks really help as far as containing germs and preventing the spread of contagious colds and illnesses. And people aren’t going to avoid you like the plague if you happen to be in a mask either. They’ll be more likely to avoid you if you aren’t wearing one (if you’re coughing up a storm that is). In most cases, you’ll be treated just like anyone else not wearing a mask.

When I was in Japan, one of our friends got sick on the trip but was still coming out with us and going to the local college and everything. The Japanese girls encouraged her to get a mask and wear it when she was socializing. She didn’t seem too keen on the idea and saw it as an inconvenience, and the Japanese girls seemed kind of disappointed in her when she wasn’t wearing it. They thought it was inconsiderate.

So if you’re in Japan and you get a cold or a bad cough, don’t be surprised if one of your Japanese friends asks you to get a mask to wear and definitely don’t be afraid to do so. I wish more people in the United States did this, especially those in schools (those illnesses spread like crazy).

Occasionally you’ll have somebody who’s pretty into Japanese culture wear a mask like this when they get sick, but because it’s not the social convention here in America, they usually (and unfortunately) end up looking kind of silly, even if their mask is quite fashionable.

Everyone Around them is Sick

Another reason you’ll see Japanese people wearing masks out in public is because they’re afraid of getting whatever illness that happens to be going around. Maybe it’s flu season or something and they’re just trying to avoid getting sick for the third year in a row because the hand sanitizer alone just isn’t cutting it.

It makes sense when you think about it. I mean, I usually come down with something near the start of summer (I’m actually getting over a cold right now) and I usually get sick again near the start of winter. Maybe if I wore a mask around these times I would be less likely to fall under the weather or avoid the illness altogether.

But like I said before, it’s not the social convention here in America and I’d look kind of silly coming into the office in the morning wearing a surgical mask. Oh well, NyQuil and Sudafed to the rescue once again.

They Have Bad Allergies

On the whole, wearing masks because of allergies isn’t as common as wearing one because of illness, but around hay fever season in Japan mask wearing out in public becomes a much more common sight. I touched on it in a post I wrote a while back about Hay Fever Hell in Japan, but along with masks, the Japanese have a lot of things around to combat allergies and you’ll definitely see a surge of mask wearers out in public during allergy season.

They’re a Bosozoku Bike Gang Member

If you see a bike gang member in Japan I’m sure that their surgical mask is not going to be what gives them away. But it is not unusual for a bosozoku member to wear a mask like this for no other reason than concealing their face. Most likely they aren’t wearing it for allergies or germ prevention (unless of course they are a very kind, caring, and socially considerate bosozoku).

And if you want to learn more about these folks, you can read all about ‘em in a post I did a while back entitled Violent Japanese Biker Gangs Just Not What They Used To Be.

They’re Too Embarrassed to Show Their Face on YouTube

Okay, so this isn’t technically in public, but you still see it a lot (if you’re on YouTube a lot and wander to the stranger corners of it like I tend to do sometimes). This one mostly applies to the ladies from what I’ve seen, but there are a lot of videos of Japanese gals doing some sort of choreographed dance or playing an instrument on YouTube/Nico Nico Douga. A lot of these girls are shy and will wear a mask like these to hide their face/identity.

Since I can’t actually ask them why they choose to do it, I can only guess. Perhaps they are shy. Perhaps they think they are unattractive. Or perhaps they think they are too attractive and want their dancing/instrumental skills to be judged honestly, not wanting to be complimented just because the audience thinks they’re hawt. See examples below.


And now you know pretty much all the reasons why you might see someone in Japan wearing a surgical mask. It’s not a weird or strange thing to do and most often they’re just looking out for the well being of others or trying to protect themselves from a seasonal illness or pollen invasion.

But what do you guys think about the wearing of masks like this? Wish you could wear one in your home country but are afraid of the social stigma? Have you ever done it in a Western country and got strange looks from others? Let us know in the comments!

    Jonadab does not now what he/she is talking about.
    While there are several types of masks, N95 masks will trap nearly all (about 95%) of particulates, including mucous and saliva droplets that contain bacteria and viruses.
    “Airbourne” viruses/bacteria don’t actually float around in the air all by their lonesome. They are carried by aeosolized droplets out of a person’s respiratory tract into the air around them.
    While a mask may not trap ALL pathogens that a person is breathing out, it will trap most….which greatly reduces the transmission rate of the disease. It’s not about maintaining a sterile environment….it’s about creating a barrier that is difficult for the pathogen to get thru.
    If a sick person is wearing a mask, they are preventing a significant percentage of respiratory pathogens from spreading into the air around them…..and if a healthy person near them is also wearing a mask, then the healthy person is significantly reducing the percentage of the reduced number of respiratory pathogens that DID make it “into the open” from entering his/her body.

    i wear a mask in japan because i am too ashamed of my acne . Can you help me with my problem? i really need your help .

  • Emily Howell

    I live in Michigan, but totally plan on getting some come this winter semester at college. It never fails that I get sick due to others hacking on their hands and then touching the doorknobs. At least if I get sick again, I can set an example that people ought to be considerate. Hell, I might wear one even if I am not sick If I see someone coughing. I don’t want to be delirious during an exam ever again.

    You’re just a pseudo-intellectual trying to be popular. As the guest said, do research before you attempt to sound intelligent.

  • pink

    Well done. Jonadab or whatever is just a pseudo-intellectual overcompensating for his lack of an education.

  • Rei

    wow stop with the greentext. What are you? From Reddit?

  • romea

    i really wish more people in the western hemisphere would be this sensible!!

    as to the effectiveness of n95 masks: for some years now, my husband & i will not enter a plane without them. before this, at least one of us would come home with a flu each time & every time… miraculously (or not… ;-)), this has stopped since we are wearing said masks.

    and, btw: WE COULDN’T CARE LESS ABOUT THE STRANGE LOOKS WE ARE GETTING!

    people get real! stop worrying about what others might think and put your health first. besides washing your hands frequently: protect yourself (and others – in case you are sick) by wearing n95 masks.
    flu-prevention really can be this simple!

    I wore a mask to work today. I got a lot of stares and people asking why I was wearing one, but when I told them it was so I don’t make them sick, they were very grateful and appreciated what I was doing. I’m in the Los Angeles area, BTW.

    For people tiring to make sense of this conversation

    Jonadab wasn’t exactly wrong as guest points out. If you haven’t got a high quality chemical grade mask then the chance of you getting infection is still theoretically* high because it wont stop water droplets from entering the mask. Guest is also right that if you breath out into something it does stop the air from spreading out.

    I would however question Heisenberg calling quotes from nytimes and wikipedia “actual facts”

    What Rich S says about N95 masks is not helpful but the rest is. Firstly the face masks worn are not ussually N95 masks since they are more expensive. Rich S says nearly what they say on the website fda.gov “when subjected to careful testing, the respirator blocks at least 95% of very small test particles” This means nothing since it fails it elaborate on what “careful testing” is and also fails to give the size of the particulates (which can vary greatly in size) some it could definitely not block while larger particulates could be blocked by a kitchen sieve.

    *Interestingly enough the masks can help stop you getting infection. A large (it’s difficult to place an exact value) amount of bacteria and viruses are passed to you by your hands not the air. A recent study (last year I think) showed that people in cities touched their faces on average between 3 and 4 times per hour. The mask helps prevent you from touching your face so helps prevent infection.

    I think the far more interesting question this raise is, is a reduction in disease transmission a good thing. If you live in a country where infection rates are lower does it mean you immune system is significantly lower so you will suffer more when you get an infection?

    probably wrote too much…….

    I think in some schools, if a student shows their face online, they get expelled. Please correct me if I’m wrong

    It helps a lot if everyone does it. Of course it wouldn’t help if only you do it. When everyone who is sick is wearing a mask, they are no longer covering their mouth with their hands, so they do not contaminate things as much when they touch things, and because everyone is doing this everything is less contaminated, so when you touch something you are not picking up as much bacteria on your hands, and you are not going to spread as much when you touch something else. Everything suddenly becomes cleaner. Of course you will still get sick, but I can see this making a significant difference. Also there will be less illness spread in the air. The only argument against this should be that when there is less bacteria being spread, and less people are being infected, our immune systems are not trained as well to fight against it. When we get the illness it might be more serious, if we don’t get it as often.

    wish more sick kunts would do this and stop spreading their pathogens and viruses around the filthy phuckers…

    I wore a mask to work during flu season maybe a year or two ago. My boss told me to stop because customers were complaining about an employee having to come into work when they’re sick. Admittedly at first I WAS sick and I kept wearing it because I didn’t want to get sick from others.

    I was told the masks are only effective for maybe a half hour, then they’re used up.

    I personally think it’s better than nothing. I suppose everybody around me says they’re not very effective and just make others uncomfortable, but the question isn’t “are they a key element in preventing the spread of illness” the question is “are they better than absolutely no barrier at all?”

  • Jenann80

    This doesn’t account for why it is primarily young females who wear these masks in Japan. Other people get sick too right?

  • Sanjay Tyagi

    Only way to assess the effectiveness of the masks is to do a controlled social experiment – an entire city should not use them for a season. This should be accompanied by city-wide measurements of incidence of cold, before, during and after the experimental stoppage. After repeating the experiment a number of times we may find if the practice helps. Does anyone have a sense of origin of this practice as to when and how it began?

  • Shayne O

    The mask will stop bacteria, but not virus (Well ,maybe a tiny bit). Unfortunately, most colds are viruses. As was sars.

    Stupidity. To give or get protection they would have to wear a hazmat suit.

  • Meeplogic

    No why most japanese youtubers wear masks is because in japan
    It is ilegal to post a vide of yourself under the age of 18
