So, you’re looking at a trip to Tokyo this month. Honestly, it’s one of my favorite times to be in the city, but if you’re expecting a cozy, snowy wonderland like you see in the movies, you might be in for a surprise. Tokyo weather this month is a weird, beautiful, and sometimes bone-dry beast.
Right now, we are sitting in the dead of winter. It’s cold.
But it isn’t the kind of "buried in six feet of snow" cold you find up north in Hokkaido. It’s a crisp, "I can see Mount Fuji from my hotel window" kind of cold. Most people don't realize that January is actually the sunniest month of the year for Tokyo. While the rest of the world is dealing with grey, slushy skies, Tokyo is often blasting you with bright blue sunshine. It’s deceptive. You see the sun, you think "Oh, it’s a nice day," and then you step outside and the Siberian wind hits your face like a frozen towel.

The Real Numbers (Not the Fluff)
Let’s talk brass tacks. You’re looking at daytime highs that struggle to reach 10°C (50°F). Once the sun goes behind a skyscraper at 4:30 PM? Forget it. The temperature drops fast, usually bottoming out around 1°C or 2°C (34°F).
Is it going to snow? Probably not. Tokyo gets maybe one or two "snow days" a year where the slush actually sticks to the ground for more than twenty minutes. Usually, if something falls from the sky this month, it’s just a very cold, very light rain. The city is remarkably dry. The humidity levels hover around 45%, which sounds fine until your skin starts peeling off.
You’ll see locals everywhere wearing surgical masks. Sure, some are avoiding the flu, but a lot of them are just trying to keep their own breath from drying out their throat. Seriously, pack some heavy-duty lip balm and hand cream. You’re gonna need it.
Why the Wind is Your Real Enemy
The temperature doesn't tell the whole story. It's the karakkaze—the "dry wind." This wind comes blowing down from the mountains, and it’s a total mood killer if you aren't dressed for it.
I’ve seen tourists walking around Shibuya in light hoodies because the thermometer said 9 degrees. Within ten minutes, they are ducking into a FamilyMart to buy those sticky heat packs (called kairo) just to survive the walk to the station.
How to actually dress
Don't just bring one big heavy coat. That's a rookie mistake. Why? Because the Tokyo Metro is heated to approximately the temperature of the sun. You will be shivering on the platform, then sweating like a marathon runner the second you step onto the Ginza Line.
- Base Layer: Uniqlo Heattech is the unofficial uniform of Japan for a reason. Get the "Extra Warm" version.
- The Middle: A fleece or a light wool sweater.
- The Shell: A wind-blocking coat. It doesn't have to be a massive puffer, but it needs to stop the breeze.
- The Secret Weapon: A scarf. If you keep your neck covered, you can handle a lot more than you think.
What's Actually Happening in Tokyo This Month
Since the sky is so clear, this is the absolute best time for photography. If you head up to the Tokyo Skytree or the Shibuya Sky deck, your chances of seeing Mount Fuji are about as high as they’ll ever be. In the summer, the mountain is usually hidden behind a wall of haze and humidity. This month? It’s standing there in all its snow-capped glory.
We also have the Hatsumode season. For the first few days of the month, millions of people cram into shrines like Meiji Jingu and Senso-ji. It’s loud, it’s crowded, and there’s a lot of hot sake being sold in paper cups.

Mid-month, keep an eye out for the Setagaya Boroichi Flea Market. It’s been running for over 400 years. You can find everything from ancient katanas to weird 1970s toys. Just be prepared to shuffle through the stalls with thousands of other people while the cold wind bites at your ears.
A Few Things That Might Annoy You
It’s not all "crisp air and blue skies." There are downsides to Tokyo weather this month.
First, the days are short. The sun sets before 5:00 PM. If you spent your morning sleeping in because of jet lag, you’ve basically missed all the "warm" hours.
Second, the static electricity is insane. Because the air is so dry, you will get shocked every time you touch a door handle or a vending machine. I’m not joking. It’s a legitimate hazard of Tokyo life in January.
The Verdict on Visiting Now
Should you come? Yes.
Travelers usually avoid winter because they’re scared of the cold, but that means shorter lines at DisneySea and easier dinner reservations in Shinjuku. The light is beautiful, the air feels clean, and the city feels "real" in a way it doesn't during the sweaty chaos of August.
Actionable Next Steps for Your Trip:
- Buy Kairo: The moment you land, go to a convenience store and buy a pack of "貼る" (haru) kairo. These have an adhesive side. Stick one on your lower back (over your undershirt, never on bare skin) and one on your chest. It’s like wearing a portable radiator.
- Hydrate Like a Pro: Buy a "hot" drink from a vending machine (look for the red labels). Not only can you drink it, but it doubles as a hand warmer while you walk.
- Check the "Wind Chill" specifically: Don't just look at the high of 10°C. If the wind speed is over 15 km/h, subtract about 5 degrees from your mental comfort level.
- Moisturize: Buy "Yuskin A" cream at any drugstore (it’s in an orange jar). It’s the gold standard for Japanese winter skin.
