The crunched up mish-mash nature of an urban Japan devoid of a need for even basic greenery and open space. Preferably with greenery in that space.
But when you find some natural beauty in Japan, its impressive.
I dunno, I lvoed Japan, but I'm the kind of guy who likes countryside and old things, well, you know, places that look like they are fairly well aged and lived in, I like rooms in a home to look like people have lived there for a while, a bit of a human feel to it.
Most of urban Japan seems chaotic, as if it cant stand a house or apartment block standing for any longer then a few decades.
I dunno, I guess especially for many Europeans, we have grown up in cities and societies that have a pride and respect in their architechural heritage, so we appriciate cities with old buildings along with new, also in the UK its just somethnig people expect, to have a reasonable patch of earth to call their own alongside a house.
In Japan I actually started seeing homes with even basic gardens and areas of open greenery as unique rather then the norm.
I saw a home nearby my girlfriends building, it had a garden, lucky to even be half the size of mine, and my garden isnt big, and i remember thinknig "Jesus, the guy who owns that must be bloody loaded!".
Apart from that I mostly enjoyed Japan, I think aslong as I could live on the edges of a Japanese city I would be fine.
I liked Ome city, it was pretty nice, I remember going on a fairly long walk to a shrine for new years, it was set in a nice place, must have been right on the edge of town though.
Its where I first descovered Yakisoba.
