What customs, way of life or products in Japan do you wish your home country would adopt?

Better manners. I go to a local izakaya in my city because the ex-pat customers are far more polite than the average restaurant or bar in my city.

So many, it's hard to list just a few.

"Oshibori" and a glass of water when you go to restaurants; not having to tip; takyubin delivery service; warm toilet seats; convenience store services; barber shops (my barber gives a scalp massage, and it's divine); good manners.

Basic intelligence and literacy, humbleness, non-religiosity.

Washlets. Oshibori. Chopsticks for salads. Polite service. Responding to customer's entering the store, rather than making customers wait until they are finished with whatever they were doing when the customer entered the store. Non-religiosity (agree with M3M3M3) Not needing to be confrontational about everything

No guns for sure. As for "better manners", I must have lived in a different Japan for nearly ten years. The sound of salarymen slurping their spaghetti at lunch is still ringing in my ears, as well as the sight of people stabbing a huge piece of meat with their fork, and repeatedly gnawing at it, rather than use a knife to cut it up.

No guns for sure.

Agree 100%.

Neither of which are bad manners in Japan.

Washlets. More oshibori. Being more accepting. Being able to have a night out in a bar without people behaving disgracefully.

Agreed. But the questions was "What customs, way of life or products in Japan do you wish your home country would adopt?", and these are ones that would definitely not fall into that category.

Love Hotels

Taking off your shoes when you enter someone's house. I started doing that years ago before I even moved to Japan because it made sense-- the bottoms of your shoes are filthy and they track dirt all over the carpet. Plus, you're probably going to be walking over that same spot in bare feet at some point that day or the next morning. It drives me crazy when people in my family sit on the sofa with their feet up while wearing shoes, or lie on the bed. Why wear shoes unless you have to for some reason? Also, pouring drinks for your friends when you're eating out. That's such a pro-social thing to do and it encourages politeness and bonding between people dining together.

The Washlet.

As others said :

polite service

oshibori

no guns

non-aggro-ness (in home country always someone with WTF you looking at?)

being able to get my wallet back intact when lost.

Washlet. Good public transport. General honesty. Limited street crime.

No tipping.

All of the above, plus people taking pride even in routine jobs. I'm sure it makes it more meaningful to do it, and for everyone receiving the service it's so much nicer, even if a bit slow sometimes.

Better manners, cleaning up after you, saying hello, etc...

Being from California where things can get tight in the city. I wish we could get "Japanese style parking garages,"especially in the SF Bay Area where it would really help clear up a lot of space and car congestion. The japanese parking system is just one of the best car inventions around and it's a shame other countries don't have them.

"Love hotels"

I second that!

No guns.

Affordable ticket prices for football matches.

I am surprised how many people love oshibori, I still can't find them to be all that exciting. Different strokes I suppose.

I think 'products' is where I find the most I want to bring back home. For example, I really like the refill packages available for soaps, pens, etc. And convenience stores...Japan does them well. Oh, and I wouldn't complain if I could get 'all I can drink' beer for 10-20 bucks back home.

Bosozoku motorbikes (minus bosozoku rider).

The U.S. needs to get rid of guns and tipping

Year-round schools. The kids here get 2 1/2 months off in the Summer to forget everything they learned in the previous 9 1/2 months.
