Hours of Sunlight and Twilight
Hakone’s winter sunshine is limited, but it changes a bit each month. In December, you get about 6.5–7 hours of sunshine per day. Days are short and clouds are frequent, so it’s the dimmest stretch of the year.
January keeps about the same amount of sunshine, but stubborn clouds can make those hours feel even shorter. In February, the weather breaks up a bit, letting in 7–8 hours per day on average.

Additional Winter Weather Factors
Winter in Hakone isn’t just about cooler temperatures. Wind, humidity, and even sea water temperatures play a role in how the season feels.
Local activities often change to match these shifting weather patterns.
Wind and Humidity Levels
Hakone sits in the mountains, so winds can be pretty variable, especially up high. The winds aren’t wild, but they definitely make chilly days feel even colder.
If you’re heading to open spots like Lake Ashi or Owakudani Valley, plan for stronger gusts.
Humidity sticks around at moderate to high levels through winter. Even when it’s cold, the air keeps a bit of moisture, making the chill feel damp instead of sharp.
That’s not quite like the dry winters you might find elsewhere.
Wind and humidity together can really affect how comfortable you feel outside. For example, a 45°F day with just a light breeze feels fine, but if the air is damp and the wind picks up, you’ll want heavier clothes.
Wearing wind-resistant layers and moisture-wicking fabrics will help you stay comfortable.
Sea Water Temperatures
Hakone isn’t right on the coast, but nearby sea water still shapes its winter weather. In December, average sea surface temperatures hover around 64°F (18°C), then cool down to about 59°F (15°C) by February.
These waters help keep air temperatures from dropping too low, especially compared to other inland areas at similar heights.
You probably won’t swim in the sea during winter, but those water temperatures matter for another reason. They influence local humidity and add to the frequent cloud cover you notice in colder months.
For most visitors, the real water highlight is Hakone’s hot springs. The contrast between brisk mountain air and naturally heated baths is a big winter draw.
Honestly, the sea’s effect on the climate just makes those onsen baths feel even better.
Weather Impact on Local Activities
Winter weather really shapes how you experience Hakone’s attractions. Colder air and the occasional snowfall turn Mount Fuji and Lake Ashi into something out of a postcard, but honestly, you’ll probably run into icy paths up in the higher areas.
Walking trails can get slippery fast, and sometimes they just close off certain routes for safety, which is understandable.
Sightseeing boats still cruise across Lake Ashi, but trust me, you’ll want to bundle up if you’re heading out on the water. The skies tend to clear up in winter, giving you some of the best views of Mount Fuji—photographers love this time of year.
Hot springs take center stage once the cold sets in. That damp chill makes soaking in an onsen almost irresistible, and honestly, it just feels right.
Museums, indoor exhibits, and ropeway rides stay open, so you’ve got options when the weather isn’t cooperating.
