Around 20 million people live in Japan's "snow zone," where a single winter brings at least five meters of snow altogether. Japan is distinct in having so much snow so far south. Life in the snow zone has inspired many innovations. Traditional homes in Gifu Prefecture have steep, snow-shedding roofs and flexible frames. People in Niigata Prefecture weave colorful textiles whose brightness can be enhanced by laying them on the snow on a sunny day. Snow creates beautiful visual effects, as well as bringing great pleasure to children. In parts of Japan, children gather in snow huts on winter evenings. Some farmers look at mountainside snowmelt patterns to help them decide when to plant rice, and one farmer even uses snow to preserve the taste of freshly harvested rice. On this edition of BEGIN Japanology, we look at snow - how the Japanese appreciate it, cope with it, and coexist with it.
