What to pack for Tokyo in December
Heading to Tokyo 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 Tokyo (ranked 10 of 12) and among the driest (ranked 12 of 12). Day temperatures are 5°C cooler than November and cooling toward January — so this month's packing list won't be identical to November's or January's.

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?
Maybe — possible with a packable down jacket, careful shoe choices (one warm + one walking), and wearing your bulkiest layer on the plane. Expect to use most of the carry-on volume.
24 suggested items total — 5 essentials, 8 clothing items, 2 pairs of shoes.
What you can leave at home

- shorts & sandals (too cool to wear comfortably)
- beach towel (unless you're brave)
- snow boots and ice grips
