What's some amazing technology they have in Japan that's very normal but as a blow your mind here

Its the small things, not anything massive.

For example, most toilet paper holders in Japan have this floating lid that sits on the toilet paper, which allows you to cleanly rip a sheet off every time, and prevent tearing a corner off.

The suica or iccoca cards (trains and subway cards) can be used to tap to pay near everywhere, including vending machines and such. Quite convienent.

You can pay many of your utility bills, in cash, at most main convienence stores. It allows for more methods of payment outside of everything tracked by credit card.

Many shower rooms ( Japanese bathrooms tend to have a full wet room for bathing) often have an advanced fan system, with a dehumidify option for drying clothes you hang in that room.

Many bathtubs have a water recirculate option, which reheats the same bathwater keeping it warm without needing to refill or add water to the tub.

Ah, one of my favorites is in many bedrooms there is a small square panel on an outside wall, and if you click it it vents to the outside, providing outside fresh air without needing to crack a full window. They often have filters built in as well.

Its becoming more common in the US now, but minisplit AC systems are ubiquitous in Japan. Its nice being able to control each bedroom separately.

I could go on. I lived there for a bit with my wife, in Osaka and in her hometown ( in Nagano).

These are all on my list of cool things I tell people about Japan. It really is a bunch of small stuff that I found great.

Another small one - most grocery stores have a packing area past payment and there's usually a little bottle with a light temporary glue next to the plastic bags. So the line moves faster and you never fumble opening the thin plastic bags

Define "here". This is an international community

I'm going to guess that he is American, only Americans think the world is flat and oddly shaped US
- Weird, seems like a lot of flat-earthers are from the UK. Not sure what your point is.
We all know a yank asked this one. They always assume we are all from the US.
- Well yea, you’re from Michigan.
  
  The person you replied to is from Nevada.
  
  I don’t see the problem here.
- No we just assume that if you know the question’s directed at Americans you’ll be an adult about it
Probably somewhere other than Japan.

Bidet toilet seats

When you go to a cloth shop you just place your bag in a box and pay. No scanning or anything. It takes less than a minute.

The employee had to help me because I was trying to figure out how to scan my stuff.

I've seen decathlon employ this in their stores as well. Think they're primarily in Europe.

It's definitely weird the first time you do it, but I'm assuming they're using RFID technology, so each product has a little microchip in its price tag.
- I was going to say the same. Decathlon is pioneering this I guess.
- And, of course, Uniqlo does it too

The car garages. I never drove a car in Japan, but it looked like there was a system and some kind of futuristic hydraulic automation thingy to put your car in an available slot??

But in general, I got a lot of retrofuturism vibes in Japan.

Also, while not technology, it is worth mentioning that people there are incredibly polite and friendly - even in Tokyo rush hour.

They have this in Denmark if I understand correctly. Like you park in on of the robot lifts, there was 5 where I was, then the machine parks your car, and when you’re done it collects it back.
- I wouldn’t say they are common but they definitely exist. The new harbour front parking in Aarhus is fully automated; you drive under the public library, which is raised on concrete pillars, and enter into any available “garage” - after you’re out of the car, you press a button to close the “garage” and the floor plate is lowered down for automated storage. An empty plate is then brought back up and the garage is opened again for the next person. It apparently increased capacity 40% to do it this way.

Meat stickers that detect ammonia and block the barcode if the meat has spoiled.

What does here mean?

Lemmy?
- Lemmy as opposed to Japan? I think OP just neglected to post his coubtry of origin.
The place where the speaker is

Much higher quality product options/expectations and far more choice because the consumer makes intelligent choices instead of spontaneous purchases based primarily on price and instantaneous gratification.

because the consumer makes intelligent choices instead of spontaneous purchases based primarily on price and instantaneous gratification.

What does this even mean?
- It’s a new paradigm of expanded potentiality portfolio synthesis with advanced KPI full-spectrum improvement sprints.
  
  Japan, baby
- It is a reference to US culture's big box store and monopoly driven markets. The USA has lots of products and niches, but very few people here seek them out.
  
  Retail here in the USA is mostly driven by big box stores and wholesale distribution chains that hold monopolies in every major product category from which consumers make purchases. These outlets tend to offer high profit margin products and limit consumer product availability to just these high profit items from convenient local retail sources. It happens in stores from your local bike shop's distribution chain to big box home improvement stores to the small business general retail killers of Walmart and Target, or local grocery stores. Either the store chain is as large as the major wholesale distributors, or the small business is dependent on the wholesale supply chain. Product profit margins are always kept low, putting a strain on any small retailers, and the wholesale distributors readily offer credit lines and the convenience of central product ordering and combined free shipping, while general shipping prices in the USA are very high for small businesses.
  
  This complex combination makes the US market mostly a situation where the consumer just goes to a big box store and buys whatever is available without doing any research or shopping around. This in turn has lead to further profit margin optimisation where even the large competing big box stores are all carrying the same physical hardware contract manufactured by the same factory with only different lettering and colors.
  
  This junk is so prevalent that even major Japanese brands like Makita are not the same high quality tools as the ones sold in Japan and are the exact same contract manufactured junk found in every other big box store's tools section.
  
  There is no path to retail market for grass roots innovations in the USA and therefore no interesting novelties or innovations in niches like there are in Japan. Stuff no doubt exists and many trying to succeed, but the distribution and big box monopolies rarely take on any product unless it is highly profitable in their middle man niches on par with their highly optimised source chain. So the only real products that can break into the market are ultra low quality over priced junk.
  
  I was the wholesale buyer for a chain of retail stores for 6 years.
Sounds like a place to live!

Can't help you mate without knowing where here is.

Gee gosh. I wonder if OP is in Angola? Or The Phillippines? Or maybe the USA?

There’s no way to know! He could be anywhere!

Good public transit is #1! So much goes into making those trains awesome.

The second one that comes to mind is vacuum tubes. They still keep them in stock. You can just walk into Tokyo Radio Tower and there's normally quite a good selection -- in a brick-and-mortar store. It blows my mind that they are still so readily available!

Water proof phones.

Most high end and done midrange phones have dust and water resistance.
