The Science Behind Drunken Salarymen

Alcohol is viewed a little differently in every culture in the world. Here in the US, we start (legally) drinking later in life than most countries, and our attitudes towards alcohol isn’t always healthy.

And then there’s Japan. Drinking is a huge part of Japanese culture; whether it’s going out to a bar with your friends, or hitting an izakaya with your coworkers, it’s hard to find a social occasion that doesn’t involve kicking back a few cold ones.

But there are also plenty of problems with alcohol in Japan. Today, Japan chugs down 6 times more booze than they did 50 years ago. The crown prince of the Japanese royal family had to be treated for alcoholism, and a few years ago, the Japanese finance minister held a press conference drunk:

Maybe nobody is more notorious for not being able to hold their alcohol than Japanese salarymen. Just a couple of beers (even light, watery Japanese beers) send salarymen stumbling down city streets late at night, neckties around their foreheads, faces beet-red.

You might think that salarymen are wusses or lightweights for getting drunk so easily, but there is actually a scientific explanation behind why the Japanese can’t always hold their liquor.

Drunken Science

A big reason so many Japanese have trouble with alcohol is because of a condition called the “alcohol flush reaction,” (or “Asian glow”). It’s a genetic condition that affects something like ⅓ of all East Asian people.

What does this Asian glow do to people? In a nutshell, it means that the body can’t break down alcohol all the way, causing even light drinking to result in really bad hangovers and bright red faces (hence the name “Asian glow”).

For relaxing times...

But besides the obvious, visible effects of alcohol on those who have the Asian glow, there are other things going on beneath the surface, chemical reactions within the body.

Japanese Mutants

Typically when somebody drinks alcohol, it’s processed by the body in two basic steps. First, alcohol is broken down into a harsh chemical, then into a milder chemical that’s basically vinegar.

The enzyme in your body that makes that important second step happen called aldehyde dehydrogenase (ALDH).  ALDH makes sure that alcohol is only in that harsh chemical form for a little bit of time.

But for some reason, about 40-45% of Japanese people are mutants.

No, not cool kind of mutants, but the regular ol’ boring kind. These people have a different kind of ALDH (called ALDH2) that doesn’t break down the alcohol as well nor as fast, leaving the alcohol in the body at that harsh chemical state for longer.

So while people with the Asian glow might not be able to shoot lasers out of their eyes or have Adamantium claws (they’re only Vibranium), this mutation is still pretty important, especially in a culture where drinking is so prominent.

    No more “I don’t get drunk fast and it’s not because I’m Japanese”-talk from my Japanese friend then… :3

    I’ve heard the Native American genetics have this same issue.

  • Hokkaidoolaf

    Pls be a bit more correct. Your title contaims ‘science’ so, it should be science. Aldehyde is not a harsh form of alcohol. It is a different kind of chemical

    Interesting article!!!

    I remember watching an Anime (Clannad After Story) and on this girls 20th birthday (yep you already know) she decided to drink alcohol, and she got drunk on the first sip. So yeah, that’s kinda understandable.  I thought it was just an Anime, and that she couldn’t hold her alcohol cause she was so fragile, and unrealistic, etc. But after reading this, I guess it’s a lot more common than I thought it was. I guess the anime had some truth to this matter.

    I didn’t mean to imply aldehyde was an alcohol, sorry. What wording threw you off?

  • http://www.tofugu.com/ Hashi

     Thank you!

  • http://www.tofugu.com/ Hashi

    I don’t know if you can get drunk on the first sip, but it’s probably not too far off :p

  • http://www.tofugu.com/ Hashi

     Huh, I hadn’t heard that before. Interesting!

  • kuyaChristian

    I think the questions is…do you suffer from this, Hashi? :P We saw you wasted on that Salaryman video! xD

  • http://ogijima.com David @ Ogijima

    Makes sense. North East Asians and Native Americans share the same ancestors.

  • K’

    I have somewere native american blood and the first time I drink (just a little of) wisky
    I was like that japanese minister of the video :3

    Here is something I want to know…  Is being Drunk looked down upon in Japan?  Some girls from different parts of Asia had a presentation in college class about how being drunk is shameful.   Does this apply to Japanese culture as well?

  • Hinoema

    That’s not just Asians. My mom is half Cherokee and gets toasted on a glass of champagne. Many Native Americans can’t hold the hootch either. (Fortunately I inherited my father’s hardy Irish-Italian drinking genes.)

  • Hinoema

    Another interesting thing is that populations that can’t process liquor effectively (Asians, Natives, and so on) are also genetically lactose intolerant.

    This article is seriously lacking in Drunk Salaryman Hashi Antics… just sayin…

    We used to cross reference studies and experiments done with Japanese/Chinese and Native American people.  As it turns out they have similar genetic tendencies and their cultural isolation histories make for interesting correlations.  The obesity research is especially striking.

    Glad to be a part of the other 2/3.  Well… maybe a minority of the majority.  My dad’s genetics make sure I can handle my alcohol (Sansei) but my mom’s (Japanese) make sure that I turn red no matter how little a sip I take. 

    Hmm… maybe I should hang out with friends by saying “Let’s get RED FACED!”

    Ooo… maybe a cocktail called the Red Face.  Sake Bombs with lipovitan or Asahi and Suntory Whiskey Boilermakers.   Must get to the drink lab!!!!!

    It’s because in Asia (or America or wherever else) people did’t drink alcohol thousends of years ago ’cause they were clever enough to boil the whater to make it drinkable, while the Europeans (and who ever else) kinda “desinfectet” it by adding alcohol. So the people drinking alcohol developed that enzyme to break it down, while the others naturally didn’t. It’s kinda like you never had a desease so you don’t develop the antibodies. Just guessing, but it’s probably the same with milk.

  • http://www.tofugu.com/ Hashi

     What is it about the obesity research that you found interesting?

  • http://www.tofugu.com/ Hashi

     Huh, I was wondering why that was the case. Where did you learn that?

  • http://www.tofugu.com/ Hashi

    I think there’s a time and a place to be drunk, but if you’re drunk outside of that space, then it’s looked down upon.

    Beer was created at the dawn of civilization. Some think that it’s one of the reasons people settled down to tend crops.

    By then, though, everyone was already spread across the world.

    There is a documentary about beer I saw, it was called something like “How Beer Saved the World” or something like that. The title and the show had to do with beer and how it has influenced history and may be the reason our civilization exists.

  • http://www.facebook.com/profile.php?id=630637211 Brandon Inoue

    Quite true.  I remember that the ancient Mesopotamians (Sumerians) created the first civilization and that they used barley based beer for everything.  Including regular internal organ washings for disease treatment.  Yes I said organ washing.
    Alcohol  also has an interesting correlation to fighting.  People who are more prone to substance addiction are also more likely to pick up arms and fight.  Psychological research has seen that those who have battled addiction are more ready to sacrifice their lives in battle than those who have never abused anything.  It’s strictly correlation though and not a cause and effect thing.

    That when 1st generation people come to America (Native or Asian), their health significant suffers for 1 or 2 generations.  Our university did a study on this and found that even with activity levels that are similar to the ones in Japan, Japanese students gain an average of 10 – 20 lbs. the first year of college in America.  Their markers of heart disease go up as well (IL-6, blood pressure, blood glucose tolerance, cholesterol levels, etc).
    It eventually evens out around the 3rd or 4th generation.  Most likely due to more cultural acclimation and the body’s ability to adapt and thrive.

    A certain population in the US is considered the most obese group in the world (per capita).  They are South American in origin (if I remember right).  Back in their home country the obesity rates are some of the lowest in the world.  In America, they live on reserved land and have some of the worst health researchers have ever seen.  It’s estimated that nearly 90% of them are obese (last I checked). 

    There was almost no obesity in China until they started to industrialize.  Obesity then skyrocketed very recently.  All signs point to more available and affordable food sources.  Of course, this is all brought to our attention because the spike in obesity correlates to exactly when KFC and McDonalds show up in their country.

    One of my old professors wanted to do genetic research on Native Americans.  According to him, a Chinese Junk ship was found at the bottom of a lake in 1800s in the northern part of America (I believe he stated that George Washington himself found it).  It predates almost all the other seafaring visitors to this land.  Since the ship was abandoned, his guess was that some of the Chinese must have settled here integrated into a native population.  He wanted to test their DNA and mitochondrial DNA to test their genetic origins and see if they cross.

    We have done so many correlation studies that I just wish I could do some double blind placebo controlled studies of how food interacts in the bodies of different ethnic groups.

  • http://www.tofugu.com/ Hashi

     Wow, really really interesting. I’d really like to hear more about that Chinese junk ship – got any more details, or is that more of a professor’s anecdote?

  • http://twitter.com/shollum Shollum

    Perhaps it has something to do with the ‘Warrior Gene’. Even though it is not a sure indicator of violence, it’s quite astonishing how many of those fighting-type people have it.

  • Deanthompson88

    Thats the best genetic defect ever, Think of the money you could save and still have an awesome time.

  • Deanthompson88

     That sounds like the girls fathers got togeather and went for the reverse psychology approach to stop their daughters from drinking if you ask me. In all seriousness though i agree there is a time and a place for everything.

  • http://www.facebook.com/profile.php?id=630637211 Brandon Inoue

    Nothing like alcohol and violence!  Maybe that’s why we have the BATF?

  • http://www.facebook.com/profile.php?id=630637211 Brandon Inoue

    I’ve tried on several occasions to find resources on it.  I’m guessing you’d have to go to the actual area to find any more information (if I’m remembering it right, the ship was located in one of the great lakes). 
    I do get some memory flashes of a Cracked article alluding to it.  But that could be false memories. 
    The only thing I was able to find was that book 1421 The Year China Discovered The World.  Extremely controversial but could possibly be where my professor got his facts from.  Even if it was all false, I’d still be willing to see how the DNA ends up.

    This mess would not have happened if the Vikings had just stayed in North America. The natives would have gained a higher tolerance to booze, resistance to Eurasian diseases, and ironworking far earlier.
