Driving in Japan

One of the more jarring/disturbing/counter-intuitive aspects of living here in the winter is the way that some roads are cleared and maintained during and after a snowfall. On many main town roads, such as the one that runs right outside of my house, there is a line of sprinklers that runs down the middle of the road. They're pretty small and unobtrusive (you can drive over them, obviously), but when there's a snowfall or freezing conditions these sprinklers spring into action, spritzing water onto the street.

"But wait," you say, "Water? On the ROAD!? When it's FREEZING?"
Yes, water. The roads are on a slight slant from the sprinklers in the middle down to drains on either side. Water is sprayed, it rolls down the sides of the road, and then it falls off. It's not terribly warm water, but perhaps my friend the Physics Ph.D./Duke Alexander B. Crew can tell you that if water is moving swiftly enough it won't freeze—and what's more, thanks to water's high heat capacity, even relatively cool water can still facilitate the melting of any snow on the road. It moves, it melts, and it's disturbing as hell to drive on—but in practice, it's a big step up from the rest of the roads.

Plowing is infrequent at best (I don't believe I've seen a plow yet, merely snow piles—evidence of their wake), and salting/sanding is unheard of, so if it's not one of the magical watery routes, it's more than a little harrowing to get around. Particularly on back country roads, normally so narrow that 2-way traffic is cautious as best; the roads might be cleared, but their new form is narrow enough with snowbanks as to make 2-way traffic all but impossible. I quickly learned this my first day back, with many a roadside pull-over to let traffic pass on the way to work.

Oh, and parking lots are similarly neglected much of the time—my usual spot, a short walk from my house, was one of the neglected, and my second day back was kicked off by 20 fruitless minutes spent trying to simply get my car out of its spot. The snow that was already underneath the wheels combined with another foot of accumulation overnight to make my itty-bitty Vivian strain and groan with no release. Eventually an unknown good Samaritan came and helped push from behind as I finally got off the snowfield and onto the street for another round of wet, slow going. At least all of the white stuff everywhere made for some pretty scenery.
