Pack light — Japan has everything you could forget — but a few items genuinely matter.
Always pack
- Comfortable, easy-off shoes (lots of walking; shoes off indoors).
- Type A power adapter if your plugs differ (Japan is 100V, flat two-pin).
- A small coin purse — you’ll accumulate coins.
- Passport (also needed for tax-free shopping).
- A way to stay online: eSIM or pocket WiFi.
By season
- Spring/Autumn: layers + a light jacket; weather swings day to night.
- Summer: breathable clothes, a fan, sunscreen, a compact umbrella (rainy season).
- Winter: warm layers, especially up north; indoor heating is strong, so layers you can shed.
Nice to have
- A foldable tote (shops may not give bags).
- Hand sanitiser and a small towel (some restrooms lack paper towels).
Then check the best time to visit and plan with the 7-day itinerary.
