Weather in Japan: The Ultimate 12-Month Guide
January
Dominant Weather Type: Sunny, with occasional light snow in Tokyo; heavy snow in northern and mountainous areas.
Temperature:
- High: 8.9°C (48°F)
- Low: 2.8°C (37°F)
- Average: 5.9°C (42.6°F)
January is Japan’s coldest month, with crisp, sunny days dominating Tokyo’s weather. Snowfall is minimal in the capital, typically 5mm across 1-2 days, but northern regions like Hokkaido and the Sea of Japan coast experience heavy snow, ideal for winter sports. Relative humidity is low at 59%, and rainfall is minimal (around 7 rainy days, 45mm total). Tokyo’s clear skies and short days (sunset around 5:30 PM) create a chilly but refreshing atmosphere. Northern Japan, particularly Hokkaido, sees temperatures as low as -25°C (-13°F) in inland areas, with significant snowfall transforming landscapes into winter wonderlands.
Best Place to Be: Hokkaido, especially Niseko or Sapporo, is a haven for skiers and snowboarders, offering world-class powder snow and events like the Sapporo Snow Festival. Hot springs (onsen) in Noboribetsu enhance the winter experience.
Worst Place to Be: Okinawa, despite milder temperatures (17-20°C), feels lackluster in January due to overcast skies and limited tourist activity post-New Year, with fewer attractions open.
What to Wear: In Tokyo, pack a thick winter coat, gloves, scarf, and warm shoes, as morning and evening temperatures can drop below freezing. For northern regions like Hokkaido, insulated, waterproof boots, thermal layers, and a down jacket are essential for heavy snow and wind chill. Even in milder southern areas like Osaka or Kyoto, a medium-weight jacket and layers are necessary for cool evenings.
January’s dry, sunny weather in Tokyo makes it ideal for sightseeing with fewer crowds, though the New Year period (January 1-3) sees closures of shops and attractions due to national holidays. Northern Japan’s heavy snow appeals to winter sports enthusiasts, while southern regions like Hiroshima offer milder winters with occasional light snow. Travelers should stay hydrated, as the dry air can be dehydrating, and check for occasional cold snaps that may bring light snow to Tokyo or heavier accumulations in mountainous areas.
February
Dominant Weather Type: Sunny in Tokyo, with light snow possible; heavy snow in northern and mountainous regions.

What to Wear: A heavy winter coat, scarf, gloves, and warm socks are crucial in Tokyo, with temperatures dipping to 3°C at night. In snowy regions like Hokkaido, thermal underlayers, waterproof outerwear, and insulated boots are necessary to handle deep snow and subzero temperatures. A medium-weight jacket suffices in milder southern cities like Fukuoka, but layers are still recommended.
February’s clear skies make it a great time to visit Tokyo’s cultural sites with minimal crowds, except around Chinese New Year. The Sapporo Snow Festival draws visitors to Hokkaido, where snow sculptures dazzle. Plum blossoms begin blooming in late February, signaling early spring in warmer areas like Okinawa.
