High / low are average daily temperatures (°C). “Feels” reflects how hot or cold it feels, allowing for humidity.
Hokkaido (Sapporo, Niseko, Furano, Asahikawa)
Arctic-clear days are common in January across Sapporo and Asahikawa, with deep powder in Niseko and the ski resorts running at full tilt; pack a heavy down, insulated boots and be ready for short daylight. Travel can be slowed by local blizzards on rural roads but city services keep most airports open. Ski lifts and onsen are crowded on holiday weekends, so book early.
Tohoku & the Sea-of-Japan Coast (Aomori, Akita, Sendai, Niigata, Kanazawa)
Snow-laden streets and powerful sea-effect snow are typical on the Sea-of-Japan coast in January-expect heavy winter coats, snow boots and occasional rail delays around Niigata and Akita. Inland Aomori and the mountains are deeply cold and perfect for winter-sports; coastal towns may be shrouded in grey skies for days. Festivals and winter seafood are highlights but travel between towns can be slow.
Tokyo & the Kanto Plain (Tokyo, Yokohama, Kamakura, Mt. Fuji approaches)
Blue, crisp winter days are common in January across central Tokyo and Yokohama-air feels cool and dry with excellent views of Mt. Fuji on clear mornings. Crowds are modest outside New Year shrine visits and the city’s illuminations are in full effect; bring a warm coat but no bulky snow gear. Trains are reliable and walking tours are pleasant in the cool air.
Central Alps & Japanese Alps (Nagano, Matsumoto, Takayama, Kamikochi, Mt. Fuji approaches)
January is deep winter in the Japanese Alps-mountain passes are snowbound, lifts run at full capacity, and alpine towns like Hakuba and Nozawa Onsen are in their prime. Pack full winter kit and allow extra travel time on mountain roads; avalanches can close high routes. Hot onsen evenings are a classic way to recover from snowy days.
Kansai & the Seto Inland Sea (Kyoto, Osaka, Nara, Hiroshima, Okayama, Takamatsu)
January brings cold, dry days to Kyoto and Osaka-winters are milder than the north but mornings bite, especially inland in Nara. Temples are less crowded and New Year shrine visits create local spikes in travel. Pack a warm coat for evenings; snow is uncommon in the lower Seto Inland Sea but possible in the surrounding hills.
Kyushu & Okinawa (Fukuoka, Nagasaki, Kumamoto, Kagoshima, Yakushima, Okinawa main and outlying islands)
January is mild on Kyushu’s plains-Fukuoka and Kagoshima see cool but comfortable days, while Yakushima can be wet and lush. Okinawa remains pleasantly warm, with daytime temperatures often in the high teens to low twenties Celsius; it’s a good winter escape for beach walks and whale-watching in southern waters. Pack a light jacket for evenings and rain protection for mountainous islands.
