Your First Trip to Japan Checklist: What to Book, Arrange, and Pack

There's a lot to get right before your first Japan trip, and a few things genuinely need to happen in a specific order. I've helped enough American friends prep for Japan to know exactly where people get tripped up — the Japan Rail Pass decision, cash logistics, connectivity, and getting travel insurance in time to actually use it. This checklist organizes everything by timeline so nothing slips through.

Two Weeks Before You Fly

I know this list looks administrative — and it kind of is. But every item here has a trip I've seen go sideways without it. The two-week mark passes faster than you think, and some of these have hard dependencies: the JR Pass needs delivery time, travel insurance has a coverage window, and peak-season accommodation can disappear overnight. I lost my first-choice ryokan in Hakone for cherry blossom week because I waited too long to book. Learned that one the hard way.

• Japan Rail Pass — decide now. If your itinerary covers multiple cities (Tokyo, Kyoto, Osaka, Hiroshima), compare the JR Pass cost against individual Shinkansen tickets. The JR Pass does not cover the Nozomi — only Hikari and Kodama on the Tokaido line, and Sakura on the Sanyo line. A concrete example: a Tokyo→Kyoto round trip on Hikari costs roughly ¥27,600, and a Kyoto→Hiroshima round trip adds about ¥22,600 — totaling ~¥50,200. The 7-day pass costs ¥50,000. Those two routes alone pay for it, and every JR train you ride beyond that is free. Buy from a licensed overseas reseller; it's cheaper than purchasing in Japan, and allow 5–10 days for delivery.
• Passport validity. Japan requires your passport to be valid for the full duration of your stay. No six-months-beyond-entry rule, but check it anyway.
• Visa. Americans don't need a visa for tourist stays up to 90 days. Nothing to arrange — just confirm your trip doesn't exceed that.
• Accommodation. Book early if you're traveling during cherry blossom season (late March–early April) or autumn foliage (mid-October–November). Ryokan in Hakone, Kyoto, and Nara fill up months ahead for peak weeks.
• eSIM or pocket Wi-Fi. You will not want to navigate Japan without mobile data. If your phone supports eSIM, activate a Japan-specific plan before you land — Airalo has Japan plans starting around $4.50 for 1GB/7 days. Prefer pocket Wi-Fi (better battery life, shareable)? Reserve it for pickup at Narita or Haneda.
• Travel insurance. Book within 10–14 days of your first trip payment — that's the window for pre-existing condition waivers and time-sensitive upgrades like CFAR. Already past that window? Still buy it. You'll lose the pre-existing waiver and CFAR option, but emergency medical coverage and medical evacuation — the most critical protections for Japan — are available no matter when you purchase. More on this below.

One Week Before Departure

• Download Google Maps offline. Search each city, tap the three-dot menu, download the offline map. Essential in tunnels and low-signal areas.
• Set up Suica on your phone. Suica (and Pasmo) IC transit cards can be added to iPhone Wallet on iPhone 8 or later running iOS 16+. Set it up before you leave the US — the process doesn't always complete reliably once you're on a foreign network. This is how you pay for trains, buses, vending machines, and most convenience stores. Cash is still accepted everywhere, but IC card is much more convenient.
• Cash plan. Plan to arrive with ¥30,000–50,000 ($200–330) in yen. Skip the currency exchange booths at US airports — the rates are genuinely bad. Your better options: convert at your US bank before you leave, or use a 7-Eleven or Japan Post ATM once you land. Both reliably accept foreign cards at much better rates.
• Confirm hotel check-in timing. Standard check-in in Japan is 3pm. If your flight lands at 7am, your room likely won't be ready until afternoon. Most hotels will store your luggage at the front desk — call ahead if you want to be sure.
• Download translation apps. Google Translate with Japanese downloaded for offline use — specifically the camera lens function, which lets you point your phone at a menu and translate it in real time. Use this constantly, especially at izakaya and local spots.
• Screenshot all reservations. Don't rely on data at the airport immigration desk. Hotel confirmations, flight info, insurance policy number — all offline.
• Check medications. Japan restricts certain common US medications, including some stimulants (Adderall is prohibited — no exceptions, even with a valid US prescription) and some cold medicines containing pseudoephedrine. Carry a copy of your prescription, keep medication in the original labeled bottle, and bring a letter from your doctor stating the purpose of the drug. Customs officers do not make on-the-spot exceptions.

Smart Packing for Japan

The packing reality most Americans don't hear before their first trip: you will take your shoes off constantly. Ryokan, traditional restaurants, some temples, even fitting rooms in certain department stores — slip-on shoes make daily life significantly easier. My favorite travel shoes for Japan are low-profile sneakers with no complicated lacing.

• Luggage size matters. Shinkansen cars have small overhead racks and no luggage compartments. Oversized bags are a real problem on busy trains. Pack as light as you can — or use Japan's takkyubin service to ship your bags from hotel to hotel for about ¥1,500–2,500 per piece. My husband and I did this for a leg from Tokyo to Kyoto and it completely changed how I pack for Japan.
• Seasonal clothes. Japanese summer (June–September) is genuinely humid — lightweight, fast-dry fabrics only. Spring and autumn have wide temperature swings between morning and afternoon; layers are essential.
• Plug adapters. Japan uses Type A outlets — two flat pins. If your charger or device has a standard 2-flat-pin plug (most phone chargers and USB-C bricks do), it works without any adapter. If it has a 3-prong plug with the round grounding pin, you'll need a simple grounding adapter. Voltage difference (100V vs 120V) is fine for modern electronics.
• Laundry. Most hotels have coin laundry. A 2-week trip with a carry-on is completely doable.
• Coin pouch. Japan has six coin denominations in active daily use — ¥1, ¥5, ¥10, ¥50, ¥100, and ¥500 — and you'll accumulate all of them fast. A small pouch keeps you organized at the register. Bonus: coin pouches in Japan are adorable — picking up a kawaii one is a legitimate souvenir.
• Small cash wallet. Paying with exact change is appreciated. A slim, flat wallet dedicated to yen makes this much easier than digging through a card-heavy one at a busy register.

Why You Need Travel Insurance for Japan

Japan has excellent healthcare — clean hospitals, thorough doctors, reasonable wait times. The issue is payment. Japanese hospitals almost always require payment in full, upfront, before you leave. For a foreign patient, an ER visit or short hospitalization can easily run ¥500,000–1,000,000 ($3,300–$6,600) out of pocket before your US insurer reimburses anything — if they do at all.

I spent years working in travel insurance, and I've seen this play out more than once. A friend of mine got hit with a ¥600,000 invoice after a two-day hospitalization in Osaka for a GI issue that turned out to be nothing serious. His US health plan eventually reimbursed part of it — after a six-month claims fight. The travel insurance he'd passed on buying would have cost him $90.

Your US health plan likely does not cover international care. Medicare does not cover outside the US. And the travel protection on your credit card usually offers minimal emergency medical — enough for a minor issue, not a hospitalization or medical evacuation (flying you home with medical staff runs $50,000–$100,000 on its own). A solid plan with $50,000–100,000 in emergency medical and full evacuation cover runs $60–$150 for a two-week trip. That's the math.

Day of Departure

• Arrive at the airport early. US to Japan is long-haul international — build in 2.5–3 hours minimum at LAX, SFO, JFK, or ORD.
• Load your Suica. Add ¥3,000–5,000 before you board so you can tap straight through trains on arrival without stopping at a machine.
• Know your airport train. From Narita: the Narita Express (N'EX) to Shinjuku/Tokyo (~¥3,070, ~60 min) or the Keisei Skyliner to Ueno (~¥2,540, ~40 min). From Haneda: the Keikyu Line or Tokyo Monorail, both fast and straightforward. Know which you're taking before you land — you'll be tired.
• Visit Japan Web. Register before you fly at vjw-lp.digital.go.jp/en for digital immigration and customs processing. It's faster than paper cards and the app works offline once your forms are submitted.
• Tipping — know the real rule. In most of Japan, tipping isn't practiced and can actually feel uncomfortable to the recipient. But there's one tradition worth knowing: at ryokan, a practice called kokorozuke (心付け) — a small cash gift, typically ¥1,000–¥3,000 — is sometimes given to the nakai-san, the attendant who cares for your room and meals, when they first come to introduce themselves. My grandmother always did this, presenting it in both hands as a quiet way of saying: I see you, and I'm trusting you to take care of us. Not expected from foreign guests — but a gesture that carries real warmth if you choose to offer it.
• Have ¥3,000–5,000 cash for your first few hours. Even on IC card, you may need cash for your first meal, a coin locker, or a taxi.
• Activate your eSIM. If you're using Airalo or another eSIM provider, activate before you board so it's ready the moment you land.

The first time I brought my American friend to Tokyo, she stopped dead at Shinjuku Station — thousands of people moving in every direction — and instead of looking overwhelmed, she looked calm. 'I thought it was going to be chaotic,' she told me. 'But it's so organized.' That's the thing about Japan for first-time visitors: the country rewards preparation. Do the work in the right order and you'll arrive feeling ready. That's the whole point of this list.
