What to Pack and What to Leave Behind When Moving from Japan to the USA
Packing for an international move is not just about filling boxes, it is about deciding what your new life in the United States actually needs. For Japanese families, professionals, and students relocating to the U.S., the challenge is balancing sentimental value, practicality, and customs rules within a shipment that has to travel across the Pacific. As a licensed door-to-door moving company, we put together this guide to help you decide what to bring, what to leave behind, and how to pack it all correctly.
Start With a Packing Plan, Not a Box
Before any tape comes out, sort your belongings into four categories: pack and ship, store in Japan, sell or donate, and discard. This step alone prevents the most common mistake we see, which is shipping items that cost more to move than to replace.
Once you know what is coming, build an itemized inventory organized by room, with a description, quantity, condition, and estimated value in U.S. dollars for each entry. This inventory supports your customs declaration, your insurance valuation, and your own sanity when unpacking. If you are shipping by sea freight, plan to have your packing finished four to six weeks before your move date to account for container scheduling and port congestion at major entry points like Los Angeles.
Sea freight transit time from Japan to the U.S. West Coast typically runs three to five weeks once your container departs, with East Coast routes running longer due to the added inland leg. These are typical ranges rather than guarantees, since port congestion, customs holds, and seasonal demand can shift the timeline in either direction.
What to Bring
Pack for your destination climate rather than the whole country. Japanese thermal wear such as Heattech is genuinely hard to find in the U.S. and worth bringing if you are headed somewhere cold. Most modern electronics are dual voltage, but bring plug adapters regardless, since Japan runs on 100V with A and B style plugs versus the 120V standard in the U.S.
Bring a supply of any prescription medications with English translated documentation, along with common Japanese over the counter remedies that are not sold in U.S. pharmacies. Keep passports, visas, marriage or birth certificates, academic transcripts, and your U.S. lease or job offer letter in a folder you carry with you, never packed in a box.
Electronics deserve extra thought beyond voltage. Label every cable and charger before packing, since an unlabeled cable is one of the most common causes of unpacking frustration at the other end. If you rely on a Japanese language keyboard or input method, bring your own hardware rather than assuming you can source it easily once you arrive.
If Japanese cooking is part of your daily routine, a rice cooker, good kitchen knives, and items like a donabe or sushi molds are worth shipping since equivalents are often hard to find. Photos, keepsakes, and other irreplaceable items should travel with you rather than in the container whenever possible.
What to Leave Behind
U.S. Customs and Border Protection prohibits fresh food, meat, plants, seeds, and soil, along with explosives, counterfeit goods, and endangered animal products. Alcohol, tobacco, medications, and aerosol products are allowed but require documentation or fall under quantity limits, so declare them rather than guess. If you are unsure whether something qualifies, ask before you pack it rather than after your shipment is already at port.
Large furniture, major appliances, and heavy books are usually better sold or donated in Japan. Voltage incompatibility alone makes most large appliances impractical to ship, and furniture is often cheaper to replace than to freight across the Pacific.
Packing Fragile and Valuable Items
Heirloom dishware, artwork, and instruments need more than bubble wrap. Our professional packing service uses ISPM-15 certified wooden crates, foam cushioning, and climate safe wrapping for exactly this kind of item, and our packing materials and documentation are built to meet U.S. customs and quarantine requirements. Label every box in both English and Japanese with its contents and room, and mark fragile items clearly on more than one side.
Documentation That Keeps Your Shipment Moving
CBP Form 3299 and a detailed English language inventory are the core documents U.S. customs will expect. Incomplete or vague inventories are the most common reason household goods shipments get held at port. For a full walkthrough of the customs process for this corridor, including what triggers inspections and how long clearance typically takes, see our guide to customs clearance from Japan to the USA.
Not Ready to Ship Everything Yet
If your U.S. housing is not settled or you are moving in phases, short and long term storage near Tokyo and Osaka is available so your belongings do not have to travel until you are ready for them. This guide covers packing specifically. For a broader overview of the full move, from budgeting to shipping method, see our complete guide to moving from Japan to the USA.
Common Packing Questions
Can I pack my rice cooker or other kitchen appliances?
Small appliances that are dual voltage generally travel fine. Large appliances built specifically for Japanese voltage are usually not worth shipping once you factor in the cost of a transformer versus buying locally.
Do I need to declare gifts or souvenirs in my shipment?
Yes. Every item in your inventory should be declared with an estimated value, including gifts, even if they were not purchased for resale. Undeclared items are one of the more common triggers for a customs hold.
