Japan is one of the few countries where over-packing is an easy mistake to make — and where Japan itself sells better versions of many things you might bring. The country has excellent pharmacies, convenience stores, 100 yen shops, and department stores that are open late every day. Understanding what Japan stocks reliably changes how you should think about your suitcase.
1. Essential Documents & Tech
Must bring
- Passport (valid 6+ months)
- Printed/digital copies of passport, insurance, bookings
- Credit card (Visa/Mastercard widely accepted)
- Cash — ¥30,000–50,000 for first few days
- Travel insurance documents
- Portable power bank (10,000+ mAh)
- Universal adapter (Type A sockets — same as US)
Less critical
- Physical guidebooks — apps and offline Google Maps are more current
- Currency converter app — Google does this
- Pocket WiFi rental — an eSIM is cheaper and simpler in 2026
2. Clothing: Year-Round Essentials
- Comfortable walking shoes — already broken in before you travel. This is the single most important item
- Slip-on shoes — easy to remove at temples and traditional restaurants where shoes must come off. Lace-ups slow you down at every shrine visit
- Layers — Japan's weather is variable within a day; a light jacket or cardigan that fits in your bag is more useful than one heavy outer layer
- Modest clothing for temple visits — shoulders and knees covered is respectful, though not strictly enforced at most sites
- Socks without holes — you will remove your shoes many times; worn-out socks attract more attention than they would at home
Autumn (September–November) additions
- Light to medium-weight jacket — September is warm (25°C), November cools significantly (12–15°C in Tokyo)
- One light thermal base layer for late November onward
- Scarf or neck gaiter — useful from October
Winter (December–February) additions
- Warm coat — Tokyo winters are cold (5–10°C typical), Hokkaido and mountain areas are significantly colder
- Thermal underlayers
- Gloves and warm hat
- Waterproof outer layer if visiting snow regions
3. Toiletries: What to Bring vs Buy in Japan
Bring from home
- Prescription medication (check legality for Japan)
- Contact lenses or glasses prescription
- Deodorant (harder to find in Japan — bring your usual brand)
- Tampons or menstrual products (limited range in Japan)
- Larger shoe sizes (above men's US 11 / women's US 10)
Buy in Japan (better/cheaper)
- Sunscreen — Japanese SPF products are excellent quality
- Basic OTC medication (pain relief, cold medicine)
- Shampoo, conditioner, body wash — hotel provides these; drugstores stock great brands
- Hair dryer — hotels always provide
- Moisturiser — Japanese skincare is exceptional value
- Umbrella — buy at a 100 yen shop or convenience store for ¥500–1,000
4. Travel Accessories Worth Bringing
- Foldable tote bag — Japan charges ¥3–5 per plastic bag at shops; a tote pays for itself in a day
- Small day bag or backpack — you will carry things every day: camera, water, jacket, souvenirs
- Luggage lock — not for security (Japan is safe) but required for some luggage forwarding services
- Packing cubes — Japan's hotels are often small; organised luggage makes a real difference
- Download Google Translate offline — the camera mode translates menus and signs in real time
5. What NOT to Over-Pack
- Clothing for every day — coin laundries are everywhere in Japan, usually ¥200–400 per wash; plan to do laundry on longer trips
- Towels — hotels always provide; onsen and sento have towels available to hire or purchase
- Large amounts of cash — bring enough for your first day; 7-Eleven and Japan Post ATMs are international-card-friendly and available everywhere
- Multiple guidebooks — one digital app is sufficient; books add weight and go out of date
- Work laptop — if you are not working remotely, leave it at home; Japan's bullet trains and cafes have reliable WiFi
6. Luggage Tips for Japan
Japan's trains and public transport are not designed for large suitcases during rush hour (7–9 AM and 5:30–8 PM). Large luggage during these times is considered inconsiderate, and some seats on shinkansen are reserved for customers with oversized bags.
The practical solution used by most experienced Japan travellers is takkyubin (luggage forwarding). Services like Kuroneko Yamato deliver your suitcase from hotel to hotel overnight for ¥1,500–2,500 per bag. This means you can travel freely between cities with only a day bag. Drop your luggage at the hotel by 9 AM and it arrives at your next hotel by the following morning.
FAQ
Yes — bring enough for your first 1–2 days (¥30,000–50,000 recommended). After that, 7-Eleven ATMs and Japan Post ATMs accept most international cards and are available throughout Japan. Card acceptance is improving rapidly in 2026, but some traditional restaurants, temples, and smaller shops remain cash only.
Japan's standard clothing sizes run smaller than Western equivalents. Taller visitors and those wearing above US L size in clothing or US size 10+ in shoes will find limited options in regular Japanese stores. Larger sizes are available at some international retailers (Uniqlo carries up to XL in most stores) and in specialty shops, but availability varies. Packing clothing you know fits well is safer than relying on shopping in Japan for larger sizes.
An eSIM is more convenient in 2026 — no device to pick up or return, no risk of losing it, and coverage is equivalent to or better than pocket WiFi services. Major providers like IIJmio, Mobal, and Ubigi offer Japan eSIMs purchasable before travel. Pocket WiFi is still a solid option if your phone doesn't support eSIM or you are travelling with multiple people sharing one connection.
