Ultimate Japan Packing List 2026: What to Bring, What to Leave Home

Overpacking for Japan hurts twice — once dragging luggage up 3 flights of stairs at Shibuya station, once discovering your hotel room has no room to open the suitcase.

Universal essentials (bring these to Japan any season)

• ●Passport + photocopies (store one copy separately)
• ●Travel insurance card + emergency contacts
• ●Plug adapter (Japan uses Type A, 100V — most US plugs fit but some need adapter)
• ●Portable charger (long train days drain phones fast)
• ●Debit card that works internationally (Charles Schwab Investor Checking, Wise = zero fees)
• ●~¥30,000 cash (many temples, small shops still cash-only)
• ●Comfortable walking shoes (you'll walk 15-25K steps/day)
• ●Reusable water bottle (free water at hotels, temples)

By season

The tech stack (essential for smooth Japan travel)

• ●International SIM or eSIM (Ubigi eSIM ~$15/10GB is best; buy before arriving)
• ●Google Maps offline maps (download Tokyo^PR/Kyoto/Osaka offline)
• ●Google Translate with Japanese dictionary downloaded
• ●Japan Travel by NAVITIME (best train app)
• ●LINE app (Japanese messaging, needed for some restaurant reservations)
• ●Currency converter app (XE.com)

Medications you CAN'T get in Japan (bring from home)

• ●Adderall / stimulants — illegal in Japan (bringing gets you arrested)
• ●Sudafed / pseudoephedrine — illegal in Japan
• ●Codeine — restricted; consult customs form
• ●Vyvanse — illegal
• ●Melatonin (higher dose) — 5mg+ requires customs approval
• ●Bring supply of: painkillers, allergy meds, personal Rx (with prescription copy)

The ¥100 store hack (Daiso, Seria)

Don't pack toiletries. On day 1, hit a Daiso or Seria (¥100 stores). Their travel section has: toothbrush, mini toothpaste, shampoo, hairbands, sewing kit, umbrella. Total spend ¥1,000-2,000 to fully stock. Saves 2-3kg of packing weight.

• ●Snack containers: ¥100 each

What to SKIP (available cheaply in Japan)

• ●Full-size toiletries (hotels + ¥100 stores stock)
• ●Umbrellas (7-Eleven ¥600 always)
• ●Chargers (Bic Camera has any type)
• ●Warm/cold weather clothes (Uniqlo everywhere; buy on arrival)
• ●Snacks (conbini > anything from home)
• ●Multiple heavy outfits (laundry in every hotel, coin laundry ¥400-600)
