Honestly the japanese public transport network is a thing of absolute wonder when compared to what we've gotta put up with in the UK*
(*: PUBLIC TRANSPORT IN NAME ONLY, FOR IT IS NEITHER, and so on. **)
((** actually I just realised that technically speaking the train networks are PRIVATE companies now, and they're only transportation in that they take people places, but holy FUCK they are a shambles, so... that ACTUALLY IS AN ACCURATE MEME holy fuck))
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.
