Shipping Your Household Back to Japan: Customs, Unaccompanied Baggage, and the 6-Month Rule

Why this is a different problem than a suitcase of medication

If you searched your way here after reading about bringing medication into Japan, you are in the wrong article for that specific question. Bringing medications to Japan covers the Yakkan Shoumei process for a traveler's personal drug supply. This article covers a different, larger problem: what happens to the furniture, electric bed, wheelchair, and boxes of household items when you or an aging parent moves back to Japan permanently, not just for a visit. The two rules overlap only at one point, which we cover in Part 3.

Customs treats your belongings differently depending on how they travel, not on how important they are to you.

Japan Customs sorts everything you bring into three legal categories, and each one has its own form, deadline, and duty treatment. Accompanied baggage is what physically travels with you on the plane. Unaccompanied baggage is what you ship separately but declare at the airport when you land. Anything you decide to send later, without having declared it on arrival, is treated as an ordinary import and loses the duty-free relocation allowance entirely. Getting this sequencing wrong is the single most expensive mistake families make when repatriating an aging parent, because the exemption cannot be claimed retroactively once you have already cleared immigration without declaring.

The legal basis is Japan Customs FAQ 7301, "Procedures for importing/exporting of Household Effects for Home Relocation." It applies to anyone who has been abroad for more than one year, or who plans to stay in Japan for more than one year going forward. Both conditions are common for a returning retiree: decades abroad on one side, a permanent move back on the other. If either condition is true, your used household effects can be imported duty-free, within a quantity customs considers reasonable for personal use, not resale.

Who this rule is actually built for

The relocation exemption is written for one-time movers, not frequent travelers with extra bags.

Customs officers are trained to distinguish a genuine household relocation from someone trying to import goods duty-free by calling them "personal effects." A returning retiree bringing a used sofa, a decade-old bookshelf, kitchenware, and clothing fits the intended profile cleanly. A shipment of unused electronics still in retail packaging does not, and customs can reclassify it as a standard dutiable import on the spot. If your household includes both genuinely used furniture and some newer purchases, separate them in your packing list so the used items are not delayed while an officer questions the new ones.

New items are not automatically excluded. Customs allows new goods with a combined overseas value under ¥200,000 to be included in the general accompanied traveler's duty-free allowance (Japan Customs FAQ 7104-2), but that allowance is a separate, smaller bucket from the household-effects relocation exemption and it is calculated per person, per entry, not per shipment.

Three routes goods can take across the border

The choice is not about cost alone; it is about what deadline and paperwork you can realistically meet.

Accompanied baggage is anything that arrives with you, checked or carry-on. It needs no special declaration beyond the ordinary customs form everyone completes, and Japan Customs FAQ 7102 covers the process. This route works for what fits in luggage: documents, a few days of medication, small electronics, a modest number of personal items.

Unaccompanied baggage is goods you ship separately, by sea or air freight through a mover, but declare on the "Declaration of Accompanied Articles and Unaccompanied Articles" (Customs Form C-5360) at the airport the day you land, even though the goods themselves are still weeks away. You submit two copies; the officer stamps both and returns one to you. That stamped copy is what lets the shipment clear customs duty-free later, so it needs to survive in a folder you will not lose for months, not a jacket pocket.

A standard import is what happens if you skip the declaration step, or if your shipment arrives more than 6 months after your own entry date. At that point Japan Customs FAQ 7103 no longer treats the goods as unaccompanied baggage; they are cleared as an ordinary commercial-style import, with duty and consumption tax calculated on the shipment's declared value like any other imported cargo.

How the 6-month rule actually plays out with a mover

The 6-month clock starts on your entry date, not on the day you hire a moving company or the day the container leaves port.

Sea freight from North America, Europe, or Australia to Japan typically takes 5 to 10 weeks in transit, and international movers commonly quote a full household shipment to Japan in the range of roughly $4,000 to $12,000 depending on volume and origin, according to shipping cost surveys of international movers serving Japan. Air freight clears in 1 to 3 weeks but can cost several times more per shipment. If you plan to declare unaccompanied baggage, book the mover and confirm a realistic delivery window before you fly, not after, so the shipment has a real chance of clearing within the 6 months.

If a shipment is genuinely going to miss the 6-month window, because of a slow mover, a delayed departure, or a family emergency that pushed back your own travel, contact the mover's Japan-side customs broker before the goods arrive. Brokers who regularly handle relocations to Japan can sometimes negotiate a limited extension with the local customs office when the delay is documented, though this is decided case by case and is never guaranteed.

Mobility aids and medical devices as household effects

Mobility and medical equipment mostly qualifies as personal effects, but quantity is where the rule bends.

An electric hospital-style bed, a manual or powered wheelchair, a walker, or a shower chair that has already been in use counts as household effects under the same relocation exemption as furniture, provided it belonged to you or a family member before the move and is not being imported for resale. Declare it on the same C-5360 form alongside everything else; it does not need a separate medical import procedure just because it is medical equipment.

A CPAP machine or similar single-patient medical device for personal use is generally allowed into Japan without a Yakkan Shoumei import certificate, but only one device per person. If you are bringing a second unit, such as a spare machine or one for a spouse who is not the named patient, customs can require the same import certificate process used for medication, which is the one overlap with bringing medications to Japan. Confirm the current single-device threshold with the certifying Regional Bureau of Health and Welfare before you travel, because device categories are reviewed periodically.

Prescription medication itself is not part of this household-goods exemption at all. It follows the separate quantity limits in the Yakkan Shoumei system, roughly a 1-month supply for most prescription drugs and a 2-month supply for most over-the-counter drugs without a certificate. If a parent is relocating with a multi-month supply built up before the move, plan the certificate application at least a month ahead, and read how to bridge the continuing prescriptions period once the local prescriber and pharmacy take over.

Vehicles, and the goods that do not qualify at all

A few categories of belongings sit outside the simplified relocation process entirely.

Automobiles can be imported duty-free as household effects, but only with a registration certificate proving the vehicle was owned and used abroad, and only if it is not resold or given away within 2 years of import approval. Vessels and aircraft follow the same used-and-owned logic. All three require the separate "Application for Duty Exemption on Household Effects" paperwork, not the simplified traveler's clearance used for furniture and boxes.

Firearms, certain plants and animal products, and items requiring a special permit under other Japanese laws are excluded from the simplified relocation process regardless of how long you owned them. If your household includes anything in these categories, resolve the separate permit before the shipment leaves, since customs will hold the entire container, not just the flagged item, until it is settled.

The decision that actually saves money

For most returning households, the cheapest strategy is shipping less, not shipping faster.

Because Japanese apartments and senior housing units are frequently smaller than a family home overseas, and because sea freight is priced by volume, families who sell or donate large furniture before the move and ship only what will not fit a Japanese layout usually spend less overall than families who ship an entire household and then discover the bed frame does not fit the new room. Before booking a mover, walk through the moving checklist for the target home's actual room dimensions.

Weigh replacement cost against shipping cost item by item for anything bulky. A queen bed frame or a large sofa can cost more to ship by sea than to sell and rebuy in Japan, once packing, insurance, and the mover's Japan-side delivery fee are added. Medical and mobility equipment is the exception: an electric bed or a wheelchair fitted to a specific person is rarely worth replacing, and it qualifies for the same duty-free treatment as furniture, so shipping it is usually the right call even when the freight cost looks high in isolation.

Bridging the gap until the shipment arrives

Plan for weeks without your goods, because the C-5360 declaration only removes the duty, not the wait.

Even a well-organized unaccompanied baggage shipment can take 6 to 10 weeks to arrive after you land, so budget for short-term furniture rental, a temporary hospital bed rental, or a serviced apartment stay for that period, especially if the household includes someone who needs a bed, bathing equipment, or mobility aids from day one. Local rental medical-equipment providers and prefectural welfare offices can arrange short-term loans of items like wheelchairs and shower chairs while your own equipment is still in transit, which is often faster than expediting freight.

If the move coincides with re-establishing pension payments or reopening a bank account, sequence those tasks in parallel with the shipment rather than waiting for the goods to arrive first. Reviewing pension when returning to Japan and banking for foreign retirees before you fly means the household has working money and income sorted out during the weeks the furniture is still on the water.
