Next time I get to go to japan, which I hope is soon, but probably won't be for a few more years yet at least, I'm actually looking forward to just... travelling around by metro all over the place, checking out things, the different districts of Tokyo, what they're all like, feeling out their particular "flavours" and just... I dunno, visiting Ueno Park again and its zoo because SHOEBILLS :D :D :D
And visiting that inn up in the mountains they were so lovely.
There's a video of one here actually, they do this alternating chirping noise a lot of them do, it's really nice. Plus the visual countdown lights on the signage for how long you have to cross, AND (dunno if it's shown in the video) how long before you CAN cross as well.
Oh also thing I forgot!!
Crosswalk jingles!!
Whereas in england both ends of the crossing beep at walkers in unison, in Japan you get a beep at one end, and THEN the other end beeps, and back and forth, whilever it's safe to be crossing, so you can tell audiably which side you're getting closer to so you know more or less how far you might be across.
Also if there's a bunch of crossings in one small area, they each have different sounds!
