日本旅遊完整行李攻略。依季節、必備 vs 不必要、百圓店祕訣、在日本買不到的藥品。重量最佳化。

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

Season	Temp	Must-pack	Skip
Spring (Mar-May)	10-20°C	Layers, light jacket, hanami blanket	Heavy coat
Summer (Jun-Aug)	25-35°C	Cooling towels, sunscreen SPF50, fan	Sweater
Autumn (Sep-Nov)	10-22°C	Layers, light waterproof, warm socks	Winter coat
Winter (Dec-Feb)	-5-10°C	Heavy coat, thermals, waterproof boots	Shorts

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.

●Toothbrush + travel toothpaste: ¥200
●Shampoo (travel size): ¥100 (hotel has full-size)
●Face wash: ¥100
●Umbrella: ¥300-500
●Reusable shopping bag: ¥100 (needed since 2020 plastic bag fee)
●Snack containers: ¥100 each
