Heavy snow covered many parts of Japan on Friday, with some western cities seeing record snowfall due to winter pressure patterns taking hold amid a weather agency warning of traffic disruptions, snowstorms and high waves.

The Japan Meteorological Agency said it expects the rough weather to continue through Sunday, mainly in northern Japan and along the Sea of Japan coast, while western Japan could see possible heavy snow as a cold air mass is expected to stay at least through Saturday.
