What to pack for Japan, without overpacking

Start with the season. Japan swings dramatically between July's humidity and February's snow, so the list above filters by month. The shorter version: comfortable walking shoes, a half-empty suitcase, a coin purse for the ¥500 coins, prescriptions in original packaging, and a power bank. Leave most toiletries at home, the drugstores in Japan are excellent and a fraction of the airport markup.

Summer (June to early September) runs 28°C to 35°C with monsoon humidity, so pack lightweight linen or cotton, breathable shorts or skirts, a UV hat or parasol, and a thin sweat towel. Winter (December to February) drops to 2°C in Tokyo and below freezing in the mountains, so layer thermal tops under a down jacket, wool socks, and a packable umbrella for the sleet. Spring and autumn need layers across both ends.

Japan dresses politely. Smart-casual lifts the experience, black, navy and neutrals slip you into the local rhythm, and bare shoulders feel out of place in restaurants and shrines. Bring layers for the temperature swings between train stations and street, and shoes you can slip off easily, since you will remove them at temples, ryokan, izakaya and many homes.

Sakura season runs late March into early April, with temperatures swinging from 8°C in the morning to 18°C by mid-afternoon. Pack layers: a light wool sweater, a packable rain shell for the surprise showers that knock blossoms loose, a long-sleeve tee, jeans or chinos, and the most comfortable walking shoes you own. A picnic blanket folds flat into the bag and earns its keep at the first hanami spot.

One cabin-sized bag for a trip of three to five days. A 24 to 26 inch checked case for a week or more. Anything bigger fights you on Tokyo trains and station stairs. The more useful rule: arrive with the case half-empty, since travelers routinely buy a second bag in Japan just to fly everything home. Takkyubin (宅急便) couriers ship a full suitcase between hotels next-day for around ¥2,000.

Yes, and it is easier than most travelers expect. Trains and station stairs punish big bags, takkyubin couriers ship anything you do buy between hotels for around ¥2,000 a leg, and konbini sell every toiletry you forgot. Pack five outfits, do laundry once a week at the hotel, and leave a third of the bag empty for the haul home. The test before flying: pack the case and walk a mile with it.

Less than you think. Plan for one cabin-sized bag on the way over, leaving the suitcase half empty for the haul home. Japan's trains and station stairs reward light luggage, and takkyubin (宅急便) couriers ship a full suitcase between hotels next-day for around ¥2,000. The most common regret across the videos we studied was packing too much before the trip even began.

Plain, dark, easy to slip off. You will remove them at temples, ryokan, izakaya, fitting rooms and most homes, so laces become friction and bright colours feel out of step. A broken-in walking sneaker in black or navy is the safest bet. Expect 10,000 to 20,000 steps a day, so this is one item not worth breaking in on the plane.

Modest but not formal. Cover shoulders, skip short shorts, and wear shoes that slip off easily, since you will remove them at temple halls and the ryokan entrance. The ryokan provides a yukata (浴衣) cotton robe to wear in the room, around the building, and at dinner. Tattoos still need covering at most public onsen, less so at private ryokan baths. Plain colours blend in best.

Probably not, if you are flying from North America. Japan uses the same flat two-pin Type A plug as the US and Canada, so most chargers work without an adapter. The voltage is 100V vs 120V at home, which is fine for phones, laptops and most modern electronics. UK, EU and Australian travelers do need an adapter, and anyone bringing a high-draw appliance like a hair dryer should check the voltage on the box.

Yes, but check the list first. Common Western medications including pseudoephedrine (Sudafed, Vicks inhalers) and codeine are banned in Japan, and ADHD stimulants like Adderall require advance permission. Carry everything in original packaging with your doctor's note. For controlled medications or larger quantities, file a Yakkan Shoumei (薬監証明) declaration with the Ministry of Health before you fly.

More than you would expect. Card acceptance has improved sharply, and tap-to-pay works on every train, but small restaurants, shrines, vending machines and most ryokan stay cash-only or cash-preferred. Carry around ¥10,000 in mixed notes and coins per day, and refill at any 7-Eleven konbini ATM, which takes foreign cards 24/7 in English. The ¥500 coin is the heaviest in the developed world, so a flat coin purse keeps the weight off your hip.

Most of your toiletries, the hair dryer, the umbrella, and the power adapter if you are flying from North America. Japanese hotels supply shampoo, conditioner, body wash and a toothbrush. Every konbini sells a sturdy clear umbrella for around ¥500. The drugstores carry better skincare and sunscreen than most bathroom shelves. Leaving these home buys you the suitcase space for the haul back.

A small hand towel. Most public bathrooms in Japan have no hand dryers and no paper towels, on purpose. Locals carry a thin tenugui or handkerchief in their pocket. Konbini sell them, so this is more a habit to start than a bag to add. The other quiet regrets: a coin purse for the heavy ¥500 coins, a small bag for your rubbish, and a power bank for Google Maps battery drain.
