Cosmetics and food can complicate the cabin plan. Narita's international-flight guidance generally requires liquids in containers with a capacity of 100 ml or less, together in a transparent resealable bag of no more than one litre, limited to one bag per passenger. Gels and products such as miso can also count as liquids. Check exceptions and any transfer-airport restrictions before packing. Narita liquid restrictions

Airport luggage delivery can reduce what you carry across Japan, but you still need an airline-compliant arrangement at departure.

Here, “tax-free” means purchases made under Japan's consumption-tax exemption system for eligible visitors. It does not remove your destination country's import or declaration rules. Keep the Japanese departure procedure and the rules for bringing goods into your home country as two separate checks.

For purchases from November 1, 2026, Japan introduces a refund method following departure customs confirmation. Complete the procedure with all your tax-free purchases in your possession, before checking your bags. Earlier purchases also require customs confirmation before checking bags containing tax-free goods. Japan Tourism Agency: new method · Japan Customs: earlier guidance
