How cold is Japan in winter for tourists?

Japan’s winter temperatures vary by region, but they often feel colder than the numbers suggest because of humidity, wind, and how much time you spend outside. Tokyo averages around 1–10°C (34–50°F) in January, while Sapporo in Hokkaido can drop to −6°C (21°F) or lower. Mountain and ski areas like Hakuba, Nozawa Onsen, and Niseko frequently sit below freezing. If you’ll be outside for sightseeing, waiting for trains, or attending winter festivals, plan for proper winter gear: insulated jacket, thermal layers, gloves, hat, scarf, and waterproof shoes with good grip.
