Packing tips for Japan
- Pack light. Trains have limited luggage space and many stations involve stairs. Big bags over 160 cm total need a reserved seat on the Tokaido/Sanyo/Kyushu Shinkansen — see our Shinkansen guide.
- Buy on arrival: toiletries, Heattech layers, umbrellas and most medicines are easy to find in Japan.
- Medicines: some common medicines are restricted in Japan; check the Ministry of Health rules before you fly (see our entry guide).
- Plugs: Japan uses Type A (two flat pins) at 100V — many devices are dual-voltage, but check.

What to Buy in Japan Instead of Packing From Home
- Uniqlo & GU basics: Heattech thermals in winter, AIRism shirts in summer, and ultralight packable down jackets are cheaper in Japan and tax-free over ¥5,000.
- Clear vinyl umbrellas & ultralight folding umbrellas: sold at every 7-Eleven, Lawson, FamilyMart, and Don Quijote for ¥600–¥1,500.
- Coin laundry in hotels: nearly all Japanese business hotels (Dormy Inn, Tokyu Stay, Sotetsu Fresa, APA) have coin-operated washer-dryers (¥300–¥500 with detergent auto-dispensed), so packing 5 days of clothes is plenty for a 14-day trip.
Frequently asked questions
Why are slip-on shoes and clean socks so important to pack for Japan?
In Japan you will remove your shoes multiple times a day—at temple halls, castle keeps (like Himeji and Matsumoto), traditional ryokan inns, tatami-mat izakaya dining rooms, and museum tea houses. Broken-in slip-on sneakers and hole-free socks save minutes at every entrance and keep your feet comfortable over 18,000–25,000 daily steps.
Can I bring prescription or over-the-counter medications into Japan?
Up to a 1-month supply of most standard prescription drugs and up to a 2-month supply of non-controlled OTC medicines can enter Japan without prior paperwork. However, stimulants containing amphetamine/dexamfetamine (Adderall, Vyvanse), codeine/hydrocodone painkillers, and pseudoephedrine decongestants (Sudafed) are strictly prohibited—check the Ministry of Health Narcotics Control Department rules and apply for a Yunyu Kakunin-sho certificate if needed.
Do Japanese hotels have coin laundry machines so I can pack for only 5–7 days?
Yes—almost every Japanese business hotel and mid-range hotel has 24-hour self-service washer-dryers on site (typically ¥300–¥600 per load with automatic detergent dispensing). Packing 5–6 days of clothing into a carry-on or medium suitcase and doing one laundry load mid-trip is far easier than hauling oversized bags through train stations.
What small daily items should I keep in my daypack while sightseeing in Japan?
Carry your physical passport (required by law for foreign visitors and needed for tax-free shopping), a small microfiber hand towel (many public restrooms lack paper towels or air dryers), a zip-top plastic bag for your own trash (public bins are rare), a 10,000mAh power bank, and a coin pouch for ¥100 and ¥500 coins.
