The Ultimate Japan Trip Packing List (Pre-Departure Checklist)

Documents & money (do these first)

• Passport with at least 6 months' validity
• Proof of onward/return travel — sometimes checked at immigration
• Travel insurance confirmation (paper or digital — don't rely on finding Wi-Fi to pull it up)
• A little Japanese yen in cash before you land — not all rural ATMs and shops take foreign cards, and cash is still king outside major cities
• A credit/debit card that doesn't charge foreign transaction fees
• IC card (Suica/Pasmo) — you can now add these directly to Apple Wallet or Google Wallet before you even land, which saves a line at the station

Connectivity

• eSIM or pocket WiFi — decide before you fly, since airport counters queue up and eSIMs need setup before you lose home signal. (We've got a separate guide comparing eSIM vs pocket WiFi if you're deciding between the two.)
• Universal plug adapter — Japan uses Type A/B outlets, same shape as the US but sometimes only 2-prong
• Offline maps downloaded (Google Maps offline areas, or a dedicated app) — don't assume you'll always have signal, especially in mountain or rural areas

Clothing & comfort

• Layers — Japan's seasons are more extreme than many visitors expect; check the specific month and region, not just "Japan" as one climate
• Comfortable walking shoes you can slip on and off easily — you'll be removing them constantly at temples, traditional restaurants, and some accommodations
• A compact umbrella — convenience stores sell cheap ones everywhere, but having your own for day one helps
• Modest clothing for temple/shrine visits — nothing strict, just avoid very revealing outfits at religious sites

Health & toiletries

• Any prescription medication in original packaging, plus a doctor's note for controlled substances — Japan has stricter rules than many countries on certain common medications (some ADHD and allergy medications are restricted). Check Japan's official customs guidance before you pack if you're on regular medication.
• Basic first-aid items — pharmacies are excellent in Japan, but having your own painkillers/motion sickness tablets avoids a pharmacy hunt on day one
• Deodorant — Japanese drugstore versions tend to be milder; bring your own if you have a strong preference

The part most checklists skip: safety prep

This is a five-minute task, not a packing item, but it belongs on the list precisely because it's easy to forget: decide what you'd do in an emergency before you're in one.

Japan is a very safe country in the everyday sense — crime is low, scams are rare compared to other major travel destinations. The specific risk worth a few minutes of prep is natural disasters, mainly earthquakes, since Japan sits on some of the most active fault lines in the world. Building codes and early-warning systems handle most of the actual danger — the real gap for visitors is not knowing where to go or what to expect, since you won't have grown up with the school earthquake drills locals have.

Neither is necessary for a normal trip. Both take less time than deciding which walking shoes to bring. For the wider picture on safety beyond earthquakes — crime, scams, traffic, health — see is Japan safe for tourists?

What NOT to bring (buy it there instead)

• Adapters/chargers beyond one — convenience stores and 100-yen shops sell cheap backups everywhere
• A full toiletry kit — drugstores (Matsumoto Kiyoshi, etc.) are everywhere and well-stocked
• Bulky rain gear — umbrellas are cheaper and more available locally than a packed raincoat
• A physical guidebook if you're comfortable with apps — most restaurants and shops now have QR-code menus and Google Maps reviews in English
