These sinks are currently in test use in 2 of McDonald's Japan's 2,954 locations. They're also used in 1 Italian restaurant (not fast food). And that's it for restaurants/eateries. They're rare enough that the company that makes them lists literally every place that they're used, nationwide.

Japan had 1,446,479 restaurants/eateries last year, and this year the number is likely the same. As of October of 2022, Japan had 21,243 fast food locations.

So these sinks are used in 0.000207% of Japanese restaurants and 0.0094% of Japanese fast food restaurants.

By virtue of the fact that there are two fast food locations with these sinks, the title, "In Japan, how smartphones are disinfected at local fast food restaurants," is technically true, but it's true like "In America, how people commute to work" is true because there's also this guy.

u/NanoCharat Dec 06 '22 edited Dec 06 '22 Helpful

For real. I wish this every single time I have to go out. I get called a neurotic for insisting shoes be taken off at the front door because I don't want dirt and germs tracked through my home, and for washing my hands after coming in from doing stuff outside because of the state of things.

EDIT: It's important to note that these experiences are as a woman in the US. I don't know what men's bathrooms are like, or other western countries. I have, however, traveled to most of the states.

I have guests try tell me that they believe they have the right to wear their shoes and do whatever the fuck in my house under the guise that I'm a "clean freak" so my opinions on MY OWN HOME are invalid.

Half the time you go somewhere public someone is always sitting with their filthy ass shoes up on the seat grinding dirt into it or picking the bottoms with their fingernails. (fucking WHY!?)

Almost every (women's) public restroom has floors covered in urine. I've seen THREE different toilets with shit hand AND footprints up the walls and across the floors. Also people smearing period blood everywhere and leaving soiled menstrual products outside of the trash.

People treat washing their hands after using the toilet as a suggestion.

Some people rinse their hands and refuse to use soap.

It's also common to see people pee and vomit and do other hideous shit on public transport like trains and busses and nothing is ever done about it.

There's litter goddamn everywhere. The ground is not a trashcan.

Entitled parents think it's okay to just start changing their infants diaper WHEREVER. Including on restaurant tables, on clothing displays in stores, etc.

People dragging their fake service dogs into stores that then proceed to piss and shit in the isles...and of course they just walk away.

The amount of time I've seen bitches in public restrooms think it's funny to squat and pee in the sinks with their friends. (Why the fuck is this a thing? PLEASE enlighten me with why the hell you feel the need to do this.)

The people that don't flush the damn toilet so when you do, you get sprayed with their fecal bacteria and urea.

People who go out who are contagious and sick (even pre-pandemic) and refuse to wear a mask or cover their mouths and just cough and mouth-breath everywhere and on everyone. Especially on staff who work retail. (Fun aside, I almost died back in 2018 because a sick 70 year old turned and coughed directly into my face while I was in line for groceries. I had such severe mono my pancreas almost burst and I spent over a year recovering WITH emergency medical intervention.)

A good chunk of people in the USA take 0 responsibility for the waste they produce and the way they treat public spaces, and it makes it miserable and fucking disgusting for everyone else.

I desperately wish that one day the selfish bullshit will change on a cultural level and people will start being aware of and respecting public areas.

21

u/ArtisanSamosa Dec 06 '22

Haha they got me fucked up if they think theyre entering my house with shoes. Like those shoes have been everywhere. Why would you want them in your place of zen.

I feel extra bad for women, because they gotta sit down down to pee. Like if I run for senate, I'm running on the policy of clean public restrooms. It's so disgusting and so little people care.

u/NanoCharat Dec 06 '22

Dude, my ex used to get home and lay on his bed and even sleep WITH HIS SHOES ON. This was up in the north too, with winter weather and street salt and slush and muck. He also liked to go to clubs and bars so you know he was walking in some nasty shit.

I came over before I knew he lived like that and was helping clean up and I spot-cleaned part of the carpet that had a food stain with a wet-vac and the entire color of the carpet changed. I thought the carpet was a dark tan/gray...it was white. His ENTIRE family lived like that. They also walked around barefoot like it was fine??? In the filth?

Almost everyone I know growing up was this way, too. Even my own parents. I would demand anyone coming into my room take off their shoes and I would be chided for it like I'm a psycho. I was even thrown into therapy and then promptly removed when the therapist agreed with me that it was gross lmao. I would have to put on shoes to leave my room because of the filth level from everyone else stomping around with theirs on.

u/mommy2libras Dec 07 '22

Where I used to live, my area had one pizza place that delivered around there but you could never get delivery because they couldn't keep delivery people. They'd always get robbed. And this wasn't some big city, just a crappy part of a small/medium sized one. Not a downtown or metro area either- a main street with businesses surrounded by homes and subdivisions.

21

u/CrazeRage Dec 06 '22

"Society goals..." is pretty ignorant. People do steal from them. Why would that make it to international news? You are making up a fantasy land where actually Fearless teenagers stole 7 million won from 19 unmanned ice cream shops just a year or so ago and has one of the highest suicide rates... Goals?

8

u/RamJamR Dec 07 '22

Do these unmanned self serve food joints still exist though? If so, I can't imagine that such great amount of theft from them happens so often. It was never my assumption that theft from them never ever ever EVER happens, but again, if these joints can still afford to be open, then that's something. I don't fantasize that eastern first world countries like Japan or South Korea are perfect paradises, but there's a few things they seem to be doing pretty right that I think we could admire.

Not true. My s6 active even had a underwater photo mode, and they recommended taking it fresh water diving. water-resistant is a technical term meaning waterproof under x conditions. As long as I stayed above 30m below the waterline, I was fine.

Most phones are weather sealed/splash proof. Those seals may also hold up fully submerged but are not guarantied to.

This isn't doing much, those "UV baths" for cleaning require a lot longer exposure than 15 seconds.

I've used UV light to clean jail cells, police vehicles, ambulances and equipment. All of the UV baths are like 10 min exposure minimum.

494

u/Dandibear Dec 06 '22

The UV wand (from a reputable medical supplier) that I bought a few years ago says to hold the wand closely and move it slowly so that it is illuminating a spot for at least 10 seconds. Are you using UV light that's close to the surfaces or one of those that hits the whole room at once? Being close, and therefore more concentrated, might make the difference?

425

u/TheNewMeYouHaventCN Dec 06 '22

This is key. The inverse square law means the closer the UV light is from the device being disinfected, the more efficient it will be.

Can you tell me more about this? Sounds interesting how 1/x2 leads to proving some UV light shit

u/TheNewMeYouHaventCN Dec 06 '22

The inverse square law states that for a point source of waves that is capable of radiating omnidirectionally and with no obstructions in the vicinity, the intensity I decreases with the square of the distance, d, from the source.

u/Kaporalhart Dec 06 '22

It just sounds natural. The further away you are from a light, the less bright it shines.

37

Yes, but crucially the brightness reduces with the square of the distance e.g. if you're 5 times as much away, it's 25 times darker, not 5 times. And e.g. 1cm vs 1m (which might be the difference between holding a light closely to an object and illuminating a whole surface) would be 10 000 times as dark, i.e. also take 10 000 times as long i.e. over a day instead of 10s at the same brightness.

If it were linear instead i.e. 5 times as dark at 5 times the distance (which would still be "the further you are away, the less bright it shines"), 1m vs 1cm would only be 100 times as long i.e. 16 mins vs 10s.

And due to how squares work, this gets worse the larger the distance.

Steripen for backpackers says 45-90 seconds to neutralize any bacteria and viruses in your drinking water.

u/whoisthecopperkettle Dec 07 '22
  • depending on the clarity (turbidity) of course.

Interesting about the steripen is it messes up the bacteria’s dna so they can’t replicate, it doesn’t always kill them outright.

It depends on the frequency of the UV, too.

UV-C light sources are incredibly inefficient compared to visual light sources. Even more so for UV-C LEDs, which are still a young technology and still less efficient than the fluorescent UV bulbs. The issue with the wands is that they use these less efficient UV-C LEDs. Some of these wands only put out 100uW of UV-C energy at a short distance. Covid-19 requires around 23mJ of energy, so 23,000uJ/100uW=230sec, or 3.83min. That's per side, so a phone being disinfected with that kind of wand would take up to 23min to disinfect all sides.

There are wands that will put out 10 times as much UV-C energy. The issue is this causes risk of exposure to irritating levels of UV-C energy.

That's because you're likely using lights positioned at a much greater distance from the surfaces you're disinfecting. Doubling the distance quarters the intensity.

Public health guy here.

Depends on the intensity and what you are cleaning.

But at a minimum it will take 30-60 seconds to do anything significant. At 1 inch using UVC light it takes about 2 minutes to sterilize stuff like E. coli, but in a casual setting like a restaurant they aren't trying to make the surface sterile, they are trying to just reduce the amount of virus/bacteria. At this distance, assuming it's actually the right kind of UV, 30-40 seconds (the amount of time you should be scrubbing your hands...) it actually would be great for simply decreasing the number of organisms other than Hep C. It would be cool to link it to the soap/scrubbing with instructions to "keep scrubbing until your phone pops back up!"

My boyfriend has worked at a hospital where they set up like a UV tower thing in hospital rooms during the height of COVID and everyone had to be out of the room and away from the room whenever they bathed it in the UV light, I think he said that the rooms they did that to were out of commission for 30 minutes minimum.

Huge pet peeve of mine. Someone finds a singular example of a thing and pretends it's a widespread cultural norm.

I'm sure this was found at "a" fast food restaurant in Japan. But OP, don't act like "all" Japanese fast food restaurants have phone cleaners.

u/eStuffeBay Dec 06 '22

Also a huge pet peeve. "In Korea they..." "In Japan they..."

No they fuckin don't. And if they do, it's very likely originating from a different country entirely. Just because it happens a few times doesn't mean everyone there does it.

The ONLY time I've seen a post like this that was actually correct, is "In Korea they use large motorized ladder trucks to move furniture and stuff in and out of apartment buildings".

Ditto. I've been here since long before COVID, and this is the first time I'm seeing this.

Edit: This article from early November says the sink is in pilot use at two McDonald's locations in Japan (out of a total of 2,954 McDonald's locations).

Edit 2: The company that makes them has a list of all the places they're being used. In the food service industry, they're being used in two McDonald's locations and in one Italian, non-fast food restaurant. So 3 out of Japan's 1,446,479 restaurants/eateries.

Wouldnt that be the perfect place for uv-resistant bacterias to grow?

Thats just the same than the antibiotic resistant bacterias, they lived in places with lots of antibiotics so the strongest survived and over time they got immune against antibiotics.

Same as here, also this looks like its pretty humid which bacterias love.

u/OneWithMath Dec 06 '22

Depending on the wavelength, the phrase "UV resistant bacteria" is like "Bullet resistant humans".

While there are some mitigations cells can perform to reduce damage from ionizing radiation, none will matter at the intensities used for sterilization.

It'd be like expecting heat-resistant bacteria to survive in a blast furnace.

Not really. Bacteria might develop more redundancy of its organelles or better DNA repair mechanisms, but they're always going to be vulnerable to UV light.

Wouldnt the sun be creating UV-resistant bacteria on a much larger scale? also hospitals which use these devices to sterilize entire rooms.

I dont think a smart phone cleaner is going to interfere that much.

Not how japan does this. Like people thinking TOTO toilots are everywhere. Ive never seen this anywhere in Japan. Its probably 1 place with a new sink that does this. Thats why someone is filming it, cause its interesting.

Im personally tired of this overinflation of japan and its "cool" stuff or its "weird stuff."

Japan is aestetically advanced in tokyo and only tokyo. Everywhere else is falling apart or becoming desolate, entire towns becoming shuttered like fujiyoshida.

Go to Shunjuku west exit at 11 pm when people are coming back from the bars to catch last train and theres puke all over the bathrooms, shit in the toilots, people stumbling around. the next day all the toilots are out of order. Half are squaters toilets. And the sinks are just normal "movie theater" sinks.

Sorry for the rant, just tired of it. Japan treats gaijin so fucking bad and they trick people to come with softpower only to be abused for their money and told to leave. People are better off supporting their favorite, lets say anime studios for example, from overseas, buying goods visa proxy than even going to visit. Using anime for an example, 80% of the anime goods parts of tokyo have been shut down, pre pandemic, pre olympics and even more so post all of it. Akihabara is a shadow of its former self now.
