Before You Go to Japan - Complete Guide

Most Japan trips go wrong not because of anything that happens in Japan, but because of what didn't get sorted out at home. A little planning spread across the weeks before departure removes almost all of the stress that first-time visitors associate with the trip.

This is the hub version of that planning: a realistic, complete guide to what to handle and when, so nothing gets left to the last, panicked week before you fly.

Start With the Big Decisions: When to Go and How Long to Stay

Before anything else, settle on rough dates and a length of stay. Japan has four distinct seasons that genuinely change the experience — cherry blossoms in spring, hot and humid summers with occasional typhoon activity, comfortable autumn foliage, and cold, sometimes snowy winters in the north. None of these are "wrong" times to visit, but each changes what you'll pack and how far in advance you'll need to book popular accommodation. If you're combining Tokyo, Kyoto, and Osaka in one trip, most travellers find that anything under ten days feels rushed once train travel time and jet lag are factored in.

Length of stay also interacts with jet lag more than people expect. Most visitors need a day or two to adjust, so building a lighter first day or two into the itinerary — rather than scheduling an ambitious full day of sightseeing straight off a long flight — tends to make the whole trip feel less rushed. It's a small adjustment, but it changes how the first impressions of the trip land.

Two to Three Months Out: Entry Requirements and Big Bookings

Check your passport's validity and any visa or entry requirements for your nationality well ahead of time — these rules do change, so verify current requirements directly with official immigration sources rather than relying on old blog posts. This is also the window to lock in international flights and any accommodation in high-demand areas or seasons, since good ryokan and centrally located hotels in popular cities can book out months in advance during peak periods like spring and autumn.

This is also a sensible point to research whether your itinerary needs any specialised bookings — a particular ryokan experience, a train reservation that requires advance planning, or a seasonal event with limited capacity. None of these need to be finalised yet, but knowing they exist means they don't get missed later when the trip is closer and other logistics are competing for attention.

One Month Out: Money, Connectivity and Key Apps

Japan is more cash-friendly than many travellers expect, even though contactless and IC card payments have expanded a great deal. Decide in advance how you'll access cash (an IC card such as Suica or Pasmo, plus enough yen for smaller shops, markets, and rural areas), and how you'll stay connected — an eSIM, a physical SIM card, or a pocket wifi router, each with different pickup or activation requirements. This is also a good time to download a train navigation app, a translation app, and an offline maps app, so they're ready and tested before you land rather than something you're fumbling with at the airport.

Two Weeks Out: Packing and Reservations

With dates and season confirmed, finalise your packing list. Layering works better than bulky items, comfortable slip-on shoes are genuinely useful for temples and traditional restaurants where shoes come off, and a compact umbrella is worth packing regardless of season. If your itinerary includes long-distance shinkansen journeys, this is also the point to reserve specific seats where you can, particularly around busy travel periods, so you're not standing for a two-hour ride.

The Week Before You Fly

In the final week, confirm your accommodation addresses (having them written in Japanese characters is genuinely useful for taxi drivers and for entering addresses into navigation apps), photograph or photocopy your important documents, and share your rough itinerary with someone at home. Etiquette basics are worth a quick refresher too — quiet voices on trains, no tipping, and removing shoes where indicated are small habits that make daily interactions smoother once you land.

A few smaller tasks are easy to overlook in this final window but pay off disproportionately:

• Photograph or photocopy your passport, insurance policy, and key bookings, and store the copies separately from the originals.
• Load your IC card onto your phone (if supported) or confirm you know where to buy one on arrival.
• Check the weather forecast for your actual travel dates rather than relying on general seasonal averages.
• Notify your bank of your travel dates if that's part of their fraud-prevention process.
• Charge every device and portable battery fully the night before you fly.

Treat this as the master checklist and each of the areas above — money, connectivity, packing, transport, etiquette — as a topic worth its own closer look once you've got the broad shape of the trip settled. That's the approach this Before You Go To Japan guide takes throughout: broad orientation first, then depth on the specific decisions that actually change your experience once you land.

Keeping It Simple

It's easy to over-plan a Japan trip down to the hour. In practice, a loose framework — dates, entry requirements sorted, money and connectivity decided, key bookings locked in, and a sensible packing list — covers the vast majority of what actually matters. Everything else tends to sort itself out once you're there, because Japan's transport and service culture is genuinely built to help visitors find their way.
