More info on how Japan solved the problems of large snowfall
Posted on | January 24, 2016 | No Comments
In much of Japan, that kind of snow—the kind that is currently producing headlines on the East Coast—is not uncommon. Japan has the most ski resorts outside of the United States, festivals for building ice sculptures andsnow shrines, and a website dedicated to the art of shoveling snow. (“[Snow removal] is not a labor, it is an exercise!”) Snow even gives an entire region—known as “snow country”—its nickname. In these hilly, mountainous areas, visitors can see Japanese macaques, or “snow monkeys,” bathing in hot springs, and traverse alpine corridors that are carved out in the winter to make them passable: On the Tateyama Kurobe route, the walls can reach up to 65 feet.
People in “snow country” have developed snow-management techniques that would be the envy of the Eastern Seaboard. A 2006 New York Times article about Tsunan, in Niigata, described some of them, leading off with the story of a woman exiting her house through a “second-story window.”
The snow has buried cars and houses and trifled with Japan’s famed bullet trains. It has flanked plowed streets with 10-foot-high walls of snow and transformed towns into white labyrinths inside which human beings scurry as if they were mice. … The snow country, or this corner of it at least, began conquering the snow in the late 1960’s. Sprinklers were installed in the middle of streets, the first one here in 1972; electrical pumps nowadays send mild underground water to melt the snow all over Tsunan. Some streets, especially those near the train station, are heated. Snowplows clear the roads for the town’s 12,000 residents, thanks to the $1 million the town spends on snow removal from its annual $50 million budget.
The “sprinklers installed in the middle of the street” are shosetsu (snow-melting) pipes, which eject warm groundwater onto the surface of the street. Morerecently developed methods involve heating roads by circulating hot water below the pavement with the help of solar power that is stored in the summer. Another snow-management system is the ryusetsuko, a channel of river water that runs alongside roads and carries chunks of snow away. Houses in snowy areas have steep roofs to make snow slide down them—although sometimes, according toSnow Engineering: Recent Advances, “deep snow accumulated on the ground reaches the snow on the roof, interfering with the sliding of snow off the roof.” (Japanese use old-fashioned snow-clearing—josetsu—techniques as well, meaninghands and heavy machinery.)https://www.theatlantic.com/international/archive/2016/01/japan-snow-country/426738/
