Japan Travel Apps & Services 2026: What to Set Up Before Your Trip (Smoker-Friendly Edition)

What categories of apps do you need in Japan?

Lists of "must-have apps" go out of date quickly — names, features, and pricing change every season. A more durable way to prepare is to think in categories: decide which jobs you need covered, pick one service per job, and verify the latest details on each service's official page just before departure. For a typical trip to Japan in 2026, six categories cover almost everything:

• Transit and route search — Japan's rail network is dense, and a route-search service that compares lines, fares, and transfer times is the single most-used tool for most visitors.
• Maps and navigation — a general-purpose map service for walking directions, plus offline map downloads for areas with weak signal.
• Translation — text and camera translation for menus, signs, and package labels; offline language packs help in basements and rural areas.
• Payments — a mix of an international credit or debit card, a transit IC card where your device supports it, and some cash for small shops.
• Ride-hailing and taxi — useful late at night, in the rain, or in areas with sparse train coverage.
• Luggage storage and delivery — coin lockers, staffed storage counters, online locker-search and booking services, and hotel-to-hotel or airport luggage delivery.

Transit and navigation

Japanese cities are best explored by train and on foot, and the difference between a smooth day and a stressful one is usually route planning. Major map and transit services generally cover Japanese rail well, including English station names, but the depth of fare information and platform guidance varies by service — check the current coverage on each provider's official site rather than relying on an old blog post. Many travelers also add a transit IC card to their phone wallet where their device and home region support it; support status changes over time, so confirm the latest official information for your specific phone before counting on it, and have a physical card or paper ticket as a fallback.

A note for travelers who smoke: all Shinkansen trains have been fully non-smoking since March 2024, so there is no longer any onboard smoking room on any line. When you plan an intercity leg, build in a few minutes to use a designated smoking area at the departure station before boarding — large stations often have one inside or near the gates, while smaller stations may not have any.

Translation and menus

Camera translation has become good enough to handle most menus, signs, and product labels, and text translation covers conversations with hotel and restaurant staff. Before departure, download an offline language pack for Japanese if your chosen service offers one — basements, older buildings, and rural train lines still have dead zones. Two pieces of signage vocabulary are worth memorizing rather than translating each time: 喫煙所 (kitsuenjo, designated smoking area) and 禁煙 (kin'en, no smoking). Recognizing these two at a glance helps you follow local rules without pulling out your phone, and keeps you from accidentally lighting up in a no-smoking zone.

Luggage storage and delivery

Dragging a large suitcase through rush-hour stations is the part of a Japan trip most people regret not planning for. The good news is that luggage logistics is a mature service category in Japan: major stations and many commercial buildings have coin lockers in several sizes, larger stations and airports have staffed storage counters, and online services let you search for and in some cases reserve storage space near where you will be. Separately, door-to-door luggage delivery services can move a suitcase between airports, hotels, and private accommodations, typically arriving the same day or the next day depending on distance — exact options, prices, and cut-off times vary, so check the current conditions on each service's official page.

For smokers there is a practical bonus: with both hands free you can actually use designated smoking areas comfortably. Many outdoor smoking spots are compact, and maneuvering a large suitcase into one is awkward at best. Dropping your bags at a locker or sending them ahead to the hotel, then moving around with a small day bag, makes the whole routine — finding a spot, stepping in, smoking, disposing properly — far easier.

Do you need an app to find smoking areas?

No — this is one category where you can skip the install. MottoSuitai is a free web service that shows designated smoking areas across Japan on a map, and it runs entirely in your smartphone browser. Bookmark the MottoSuitai map before you leave, or start from the smoking area map page, and you can search by your current location or by district with nothing to download. If you want the full reasoning on why a browser beats an app for this particular job — storage space, no account, instant updates — see our guide to finding smoking areas without an app.

Why does this matter enough to prepare for? Because the rules in Japan are stricter than many visitors expect. Indoor smoking is generally prohibited under the revised Health Promotion Act, fully in force since April 1, 2020, with smoking allowed only in separately ventilated smoking rooms. Many city-center districts also ban smoking on the street by local ordinance, with on-the-spot fines of roughly 1,000–2,000 JPY. And note that smoking under the age of 20 is prohibited by law in Japan. Knowing in advance where the designated areas are — near your hotel, near the stations you will use — removes all the guesswork.

Setting everything up before departure

A practical checklist for the week before your flight:

• Install and sign in to one service per category (transit, maps, translation, payments, ride-hailing) while you still have your home phone number for SMS verification.
• Confirm your credit or debit card works for overseas online payments, and tell your card issuer you will be traveling if it requires travel notices.
• Download offline maps and an offline Japanese language pack if your chosen services offer them.
• Arrange connectivity — an eSIM, SIM card, or pocket Wi-Fi — and test it before departure if activation is possible in advance.
• Look up luggage storage or delivery options for your arrival day, especially if your hotel check-in is in the afternoon and you land in the morning.
• Bookmark the MottoSuitai map in your browser and check the designated smoking areas around your hotel and main stations in advance.
• If you smoke, plan to pick up a portable ashtray at a convenience store on arrival — it costs a few hundred yen and protects you from littering fines.
• Re-check the official pages of every service you plan to rely on; features and supported regions change, and the latest official information is the only reliable source.

Apps are only half of the preparation — the other half is knowing the rules themselves. For a complete overview of where smoking is and is not allowed in Japan, including street smoking ordinances, heated tobacco, and prices, read our complete guide to smoking in Japan as a tourist before your trip.
