What to Wear in Japan Today

Figuring out the right outfit can save you a lot of discomfort. Based on today’s conditions in Japan, here’s what we recommend:

Cold weather calls for serious layering. A thermal base layer, followed by a warm sweater or fleece, topped with a sturdy winter jacket. Gloves, a scarf, and a warm hat are strongly recommended — your body loses a significant amount of heat through your head and hands. Waterproof boots are a must with precipitation in the forecast. If you’ll be outdoors for extended periods, consider thermal socks and hand warmers.

What Is the Climate Like in Japan?

Japan experiences a classic four-season climate with meaningful variation throughout the year. Winters can be quite cold with the possibility of snow, springs bring warming temperatures and blooming nature, summers are warm and often the driest period, while autumn showcases cooling temperatures and changing foliage. This variety means you’ll want a wardrobe that adapts to every season.

In February, which falls in winter — the coldest months with short days, and potential for snow or frost depending on location, conditions in Japan are typical of the seasonal pattern. The forecast data above gives you the most accurate real-time picture of what to expect right now.
