Toilets that have the sink above the tank, so water washes your hands and then fills the bowl underneath.
Loudspeakers that play a little melody at dusk, to accompany the sunset and to warn children that it is time to head home.
These loudspeakers (and there are many of them) primarily warn communities of earthquakes, hurricanes, and other natural disasters. The music is played each day at the same time, sometimes more than once, to test the system.
This means you can swing by after work without bringing your smelly shoes. There are many of these stations near the largest parks in Tokyo.
Taxis that close and open their doors automatically, so you don’t need to worry about slamming them shut.
Restaurants that make you choose your meal on a vending machine before you enter, so staff inside can concentrate on your meal rather than your cash.
They’re located outside, and you get your order on a slip. You hand it to the staff when you enter the store.
Stores that sell noodles and have a hot water dispenser near the exit, so there’s no need to go home and boil water for a snack.
Ice cubes stored in plastic cups for cheap iced coffee. You just add the coffee near the exit after you have paid.
Umbrella holders on bikes, so you can cycle with both hands on the handlebars when it is raining and not get wet.
I know this sounds obvious, but many train stations, like ones in the UK, only have one or two terrible sandwich shops next to a station.
In Japan, there can be entire malls full of food located next to your train platform. It makes sorting out dinner for a journey a snap.
Train stations, like in Osaka, are given a letter and a number, so knowing when to get off is a breeze.
No need to head home and have a bath after work when you can just head to a sento. They are cheaper than a hot drink from a store.
There are also many onsens, where the water comes from a volcanic hot spring nearby. It’s pretty incredible.
