Why Japan Requires a Different Packing Approach
Japan has a unique combination of factors that affect what to pack: its incredible convenience store and pharmacy networks mean many everyday items are cheaper and more readily available there than at home; its strict customs rules mean some items cannot be brought in; and its culture (shoes on and off constantly, walking distances, onsen visits) requires specific gear that most packing guides overlook.
This guide is organised as: what to definitely bring, what to buy in Japan, what NOT to pack, and seasonal specifics.
Documents and Money: Non-Negotiables
- Passport — Valid for at least 6 months beyond your entry date.
- International Driving Permit (IDP) — Required if you plan to rent a car. Must be obtained in your home country before departure. See our IDP guide.
- Travel insurance documents — Japan’s excellent healthcare is expensive for uninsured foreigners. Comprehensive travel insurance is strongly recommended.
- Japan Rail Pass (if pre-purchased) — Must be exchanged at a JR office on arrival with your exchange order.
- Cash (yen) — Japan remains heavily cash-dependent outside major cities. Budget ¥20,000–¥30,000 in cash on arrival. Use 7-Eleven ATMs (accept international cards most reliably).
- IC card — Get a Suica or Pasmo at the airport on arrival for seamless subway travel.
Electronics and Connectivity
- eSIM or data SIM — Essential. See our SIM card guide. Pre-activate an eSIM before your flight.
- Universal power adapter — Japan uses Type A plugs (two flat prongs, same as USA/Canada). If you’re from North America, no adapter needed. All others need a Type A adapter. Japan runs on 100V (US/Canada use 120V, Europe uses 220V) — most modern devices (phone chargers, laptops) handle this automatically.
- Portable battery pack (power bank) — A must for full days of navigation. 20,000mAh is the sweet spot.
- Offline Google Maps — Download Tokyo, Kyoto, and Osaka before departure.
- Google Translate app — Download Japanese language pack offline. The camera function reads Japanese text in real time.

Clothing: What to Actually Pack
Japan involves a lot of walking — 15,000–25,000 steps per day is common for active sightseers. Prioritise comfort over fashion.
- Comfortable walking shoes — Bring shoes that slip on and off easily (shoes are removed frequently at temples, ryokan, and some restaurants). No elaborate lacing systems.
- Layers — Japanese buildings are aggressively air-conditioned in summer and sometimes underheated in winter. A light packable jacket covers both extremes.
- Compact umbrella — Japan’s weather is unpredictable. A small folding umbrella fits in any bag. Available everywhere in Japan for ¥500–¥800, but worth packing one to skip the first-day scramble.
- Modest clothing for temples — Shoulders and knees covered for temple/shrine visits. A light scarf or cardigan works.
- Light rain jacket — For hiking or prolonged outdoor sightseeing in wet weather.
What to Buy in Japan (Don’t Pack These)
- Toiletries — Japanese pharmacies (Matsumoto Kiyoshi, Sundrug) have excellent skincare products, sunscreen, and toiletries at low prices. Don’t fill your bag with heavy bottles from home.
- Over-the-counter medication — Available everywhere, but note that some Western OTC medications containing pseudoephedrine (Sudafed, certain cold medicines) are illegal in Japan. Check the Japanese customs prohibited items list before packing any medication.
- Phone charging cables — 100 yen shops (Daiso) sell decent quality cables. Don’t stress if you forget yours.
- Snacks — Convenience store snacks in Japan are genuinely better than anything you’d pack from home. Leave the space.
- Pocket tissues — Japanese marketing often involves free pocket tissue distribution on busy streets. You’ll accumulate more than you need within days.
What NOT to Pack (Japan-Specific Restrictions)
- Codeine-containing medication — Illegal in Japan. Check all medications against the Japan Customs Narcotics/Stimulants prohibited list.
- Poppy seeds — Technically regulated under Japanese drug laws.
- Drone without registration — Bringing a drone requires advance registration with Japan’s Ministry of Land.
- Large amounts of cash (over ¥1,000,000) — Must be declared at customs.
- Counterfeit goods — Strict enforcement at customs.
Seasonal Packing Specifics
Spring (March–May): Layers essential — mornings and evenings are cool even when cherry blossoms are at their peak in late March/early April. Pack a medium-weight jacket alongside t-shirts.
Summer (June–August): Japan’s summer is brutally humid. Lightweight, breathable fabrics only. Pack a hand towel or cooling towel — you’ll use it constantly. Sunscreen (SPF50+) and a portable fan are essentials. Avoid dark colours.
Autumn (September–November): The most comfortable packing season. Light layers for warm days, a medium jacket for evenings. Rain is possible. The most photogenic season — leave space in your luggage for shopping.
Winter (December–February): Pack genuinely warm layers — Japan’s outdoors can be very cold, especially in Kyoto (which has the wind tunnel effect between its mountains) and mountainous areas. Thermal underlayers, a proper coat, gloves, and scarf. Indoor heating in Japan is excellent; dress in removable layers.
Special Packing for Car Renters
If you’re renting a car — particularly a JDM sports car from Samurai Car Japan — pack your IDP (International Driving Permit) and home country driving licence. Pack a compact camera (dashcam-style, or a GoPro) if you want footage of your mountain pass drives. Most importantly, pack an eSIM or data SIM for navigation.
