Quicky: although, like back home, mirrors are used in some unclear situations in traffic, the Japanese have almost made an art out of placing them in strategic positions.
Quicky: it’s not obligatory to have a red tail light. Having a white front light and a red reflector at the back is enough. But, but, but…?
Quicky: my ultra deluxe compact photo camera (which is taking lots and lots of very nice pictures — they will follow) seems to be running Windows 95 or Vista because it crashes and freezes multiple times per day. Otherwise, I am so very happy with it. <3
Quicky: you can always tell at what operator’s station (train, subway, or otherwise) you are because each operator will play different sounds and tunes at for example entrances, platforms and moments of arrival.
Quicky: when spontaneously visiting a restaurant, be prepared to have a need for a “reserve” (that is, a reservation) or look for foodstuffs elsewhere. This looking elsewhere can take lots of time, mind you.
Quicky: traffic lights blink yellow where I come from, to indicate that they’re out of commission for the moment. They may blink red in Japan. Be careful.
Quicky: you don’t bring your wet umbrella into a store, that’s just impolite what with the floor getting wet from your dripping umbrella. Instead you are offered some kind of condom to stick it into (or so I’ve heard) or are required to leave your umbrella at the door in a designated holder.
Quicky: you are easily underdressed in Japan. Many folks, even in the simplest of jobs (no offense!), will wear a uniform. Yesh, that does impress, I must admit.
Quicky: as said, many things make noise. For example, (some) trucks turning left or right will have a recorded female voice playing, warning it’s surroundings of this fact.
Also: while there is very little green (nature) to be seen (except in kōen, parks), crickets are heard everywhere. Even in rogue flower pots or in front of the central station.
Quicky: no matter where in the world you are, to kids the black “stripes” in zebra crossings are lava.
