What do people get wrong about posting souvenirs home from Japan?
This answer is a draft. It stays unpublished until legal review and source verification are complete.
Shopping in Japan often ends with a suitcase that will not close. The post office is the answer more often than an extra bag — Japan Post is cheap, reliable and everywhere — but the rules, the paperwork and the size limits are not obvious.
The services (Japan Post, international)
| Service | Speed | 5 kg to US/Europe (approx.) | Notes |
|---|---|---|---|
| EMS | 3–7 days, tracked, insured to ¥20,000 | ¥10,000–15,000 | Max 30 kg; size limit 1.5 m longest side |
| Airmail parcel | 1–2 weeks | ¥8,000–12,000 | Tracking optional |
| Economy air (SAL) | 2–3 weeks | ¥6,000–9,000 | Suspended to some countries |
| Surface (sea) parcel | 1–3 months | ¥4,000–6,000 | Cheapest; fine for books, ceramics packed well |
| Small packet (up to 2 kg) | 1–2 weeks | ¥1,500–3,500 | For light items |
- Customs declaration: since 2021, most destinations require electronic advance data — fill in Japan Post's "International Mail My Page" online or use the counter tablet; handwritten labels may be refused for some countries.
- Prohibited or restricted: lithium batteries (device-installed only, limits apply), aerosols and perfume (flammable — not by air), meat products and many fresh foods (destination rules), knives (some countries), cash.
- Boxes: buy at the post office (¥100–400) or reuse; hotels will often post parcels for you for a fee.
- Your country's duty-free allowance applies to posted goods too — and two big ones have gone: the US ended its $800 duty-free rule for postal goods on 29 August 2025 (only gifts under $100 stay exempt), and the EU abolished its €150 customs-duty exemption from 1 July 2026. Expect duty/VAT on most parcels; check your customs authority before posting.
[Verify] Rates and services with Japan Post's international mail rate finder (they change yearly); prohibited items with both Japan Post and the destination's customs authority.
Misunderstanding 1｜It is cheaper to pay excess baggage
Airline excess-baggage fees run ¥5,000–15,000 per bag or per kilo band; a 5 kg surface parcel at ¥4,000–6,000 is usually cheaper if you can wait.
Misunderstanding 2｜Any post office can handle it
Any post office can accept international parcels, but small ones may have staff unfamiliar with the electronic form. Main post offices in cities have English forms and long hours.
Misunderstanding 3｜Write the address and hand it over
Many destinations now require the electronic customs declaration; a handwritten CN22/23 alone can be rejected. Do it on your phone before you queue.
Misunderstanding 4｜Anything you bought legally can be posted
Perfume, aerosols and most cosmetics with alcohol cannot go by air; lithium batteries have strict rules; food depends on the destination (meat almost never). Ask at the counter with the item visible.
Misunderstanding 5｜Duty is paid in Japan
Import duty and VAT are charged at the destination, if above your allowance, and usually collected on delivery — except for the US, where Japan Post now requires duties to be prepaid via its app before the parcel is accepted. Declare honestly; undervaluation causes delays and fines.
