Tokyo Weather in December: Temperature, Rainfall & What to Pack

📒 Tokyo Climate & Weather Overview

Located on the eastern coast of Japan, Tokyo experiences four distinct seasons, a world away from the year-round tropical climate many travellers from Singapore are used to. The city's geography means it enjoys warm, humid summers and cool, dry winters. 

Understanding the Tokyo climate is key to a comfortable trip, as the weather in Tokyo by season can dramatically change your sightseeing plans.

For those accustomed to constant humidity, the crisp, dry air of a Tokyo winter can be a refreshing change. Instead of sticky heat, visitors are met with chilly mornings and clear, sunny skies. 

The average temperatures in Tokyo fluctuate significantly throughout the year, making it a city where your packing list for March looks very different from your list for August.

Seasons in Tokyo

• Spring (March–May): This is a beautiful time with mild temperatures and the famous cherry blossoms. It's comfortable for walking, but expect some light spring showers.
• Summer (June–August): Tokyo's summer is hot and humid, often feeling quite similar to Singapore. The season kicks off with a rainy period known as tsuyu in June and July.
• Autumn (September–November): As the heat and humidity subside, autumn brings comfortable temperatures and stunning foliage. This is widely considered one of the best times to visit Tokyo.
• Winter (December–February): Winter is cold, dry, and generally sunny. Snowfall in central Tokyo is rare, but the clear skies often provide spectacular views of Mount Fuji from city viewpoints.

❄️ Does It Snow in Tokyo in December?

Snow in central Tokyo in December is possible but not likely—it’s usually a cold, clear and dry month with only the occasional light flurry that rarely settles.​

Average December temperatures hover around 5–12°C, so if you’re dreaming of deep powder you’re better off day‑tripping to ski regions like Nagano or Tohoku instead of relying on snowfall in the city itself.

🎒 What to Pack for a Trip to Tokyo in December

Packing correctly is essential for enjoying the Tokyo temperature in winter, especially when you're coming from a tropical climate. The key is layering, which allows you to stay warm outdoors and comfortable inside heated buildings and trains.

Clothing Essentials:

• Thermal Base Layers: Long-sleeved thermal tops and leggings (like Uniqlo's HEATTECH) are a must to wear under your clothes.
• Mid-Layers: Pack a few fleece jackets, jumpers, or cardigans to wear over your base layer.
• Warm Outer Jacket: A windproof down or padded jacket is crucial for staying warm, especially in the evenings.
• Trousers: Jeans, corduroys, or lined trousers will be much warmer than lightweight materials.
• Comfortable Boots or Shoes: Choose waterproof footwear with good grip, and pair them with warm socks.

Weather Gear:

• Scarf, Gloves, and Beanie: These are non-negotiable for protecting you from the cold wind.
• Lip Balm and Moisturiser: The dry, cold air can be harsh on the skin.
• Sunglasses: Winter days are often bright and sunny, so a pair of sunglasses is surprisingly useful.
• Hand Warmers: These small, disposable heat packs (kairo) can be bought in any convenience store and are perfect for keeping in your pockets.

Travel Accessories:

• Power Bank: Cold weather can drain phone batteries faster than usual.
• Daypack: To carry your layers, water bottle, and any shopping you do.
• Reusable Water Bottle: Stay hydrated, even though it's cold.

Pro Packing Tips:

• Indoor heating in shops, restaurants, and trains can be very effective. Layering allows you to remove your jacket and jumper to avoid overheating.
• If you're short on winter clothes, consider buying affordable and quality items from Japanese brands like Uniqlo or Muji upon arrival.
• Leave the umbrella at home. December is one of Tokyo's driest months, and hotels often provide one if needed.

Must-Know Tips

• Weather Preparedness: Always check the daily forecast, paying attention to the "feels like" temperature, which can be lower due to wind chill. It gets dark early (around 4:30 PM), so plan your outdoor sightseeing for earlier in the day.
• Cultural & Safety Considerations: New Year is a major holiday in Japan. Many shops, restaurants, and attractions may close from around 29 December to 3 January. Plan accordingly if your trip spans this period.
• Practical Planning Tips: December is a popular travel month, so it's wise to book accommodations early to secure good rates. A Suica or PASMO travel card is essential for navigating the city's excellent public transport system with ease.
