What to pack for Sapporo in December
Heading to Sapporo in December? Here's a packing list built directly from local climate averages — not generic blog advice.
December is one of the coldest months of the year in Sapporo (ranked 10 of 12) and among the rainiest (ranked 1 of 12). Day temperatures are 8°C cooler than November and cooling toward January — so this month's packing list won't be identical to November's or January's.
Essentials
- ★ Passport + a photocopy stored separately Travel documents
- ★ Phone + charging cables (USB-C, Lightning as needed) Daily essentials
- • Refillable water bottle (1L) Reduces single-use plastic + saves money
- • Compact daypack (15–20L) For day trips, hands-free walking
- • Travel-size first-aid kit (band-aids, ibuprofen, antihistamines) Pharmacy access varies
Tops
- ★ Thermal merino-wool base layers (3 sets) — e.g. Icebreaker, Smartwool Avg high only 0.2°C — base warmth without bulk
- ★ Heavy wool or cashmere sweaters (2) Insulation against deep cold
- • Fleece mid-layer (e.g. Patagonia R1, Uniqlo fleece) Temperature regulation
Bottoms
- ★ Insulated/lined trousers (2) — Uniqlo HEATTECH lined or similar Cold weather
- • Heavy jeans or wool pants (1) Backup for travel days
Outerwear & layers
- ★ Heavy down parka rated to −20°C (e.g. Canada Goose, Fjällräven, Uniqlo Ultra-Light Down + shell) Overnight lows -6.8°C
- ★ Insulated waterproof snow boots Snow + ice protection
- ★ Wool beanie + thick scarf + insulated gloves Heat retention at extremities
Rain & weather protection
- ★ Full waterproof shell jacket (Gore-Tex or similar — NOT a 'water resistant' soft shell) 24 rain days, 69 mm
- ★ Compact umbrella (windproof, vented) Heavy rain — basic umbrellas invert in wind
- ★ Quick-dry pants (1 pair) Cotton/jeans become miserable when soaked
- • Waterproof phone pouch + dry-bags for electronics Heavy rain WILL find its way in
Footwear
- ★ Insulated waterproof boots (Blundstone, Sorel, or hiking-grade) Cold + possibly wet conditions
- ★ Wool socks (5+ pairs) — Smartwool, Darn Tough Warmth and dryness; cotton socks freeze fingers in damp cold
Accessories
- • Lip balm with SPF + thick hand cream Cold dry air cracks skin fast
Power, voltage & adapters
- ★ 100V at 50/60Hz Mains electricity standard for Japan
- ★ Plug types: A, B (Type A — flat 2-pin (US/Canada/Japan style)) Most common: A. Older buildings may also use B.
- • From the UK/Ireland: bring a G→A travel adapter UK Type G plugs don't fit Japan's outlets
- • From continental Europe: bring a C/F→A travel adapter EU Type C/F plugs don't fit Japan's outlets
- • If your device is labeled '220–240V only' (common for European hairdryers/kettles), it WILL underperform or not work at all here. Most phone/laptop chargers are dual-voltage — they're fine. Japan runs 100V — too low for EU-only 230V devices
- · Easiest option: a universal travel adapter (e.g. Anker, Epicka) that handles A/B/C/E/F/G/I in one — covers ~95% of countries. If you travel to multiple regions
❌ Can you carry-on?
Probably not — winter coat, insulated boots, and thermal layers in December push most travellers into a checked bag, unless you're a committed minimalist with a dedicated cold-weather travel system.
26 suggested items total — 5 essentials, 8 clothing items, 2 pairs of shoes.
What you can leave at home
Based on Sapporo's December climate, here's what won't earn its bag space:
- shorts & sandals (too cool to wear comfortably)
- beach towel (unless you're brave)
- delicate suede or leather shoes (they'll get ruined)
- snow boots and ice grips
