Your IC card maxes out at 20,000 yen and only tops up with cash

A Suica or Pasmo card is the single most useful thing in your pocket in Japan, but it caps at a maximum stored balance of 20,000 yen, so it is a tap-to-ride card, not a wallet for big purchases. The bigger catch for tourists: a physical Suica can only be topped up with cash at station machines and convenience stores, never with a foreign credit card. The exception is a Suica added to Apple Wallet on an iPhone, which you can recharge with a card via Apple Pay.

Android users still cannot get a digital Suica

Japan launched a Welcome Suica Mobile app on March 6, 2025, but it runs only on iPhone and Apple Watch, and the older Mobile Suica app for Android only works on a phone actually bought in Japan. That means Android travellers cannot load a virtual Suica and must buy a physical green card or Welcome Suica at the airport or a JR station. IPhone users have it easy: open Apple Wallet, tap plus, choose Travel Card, scroll to Japan and add Suica before you even land.

Japan is still cash-heavy in exactly the places you most want to visit

Tap-to-pay and IC cards are everywhere in city chains, but small family restaurants, rural shops, shrines and temple offering boxes frequently remain cash-only. The standard local move is to carry around 10,000 yen in cash as a buffer and pull more from a 7-Eleven (Seven Bank) ATM or a Japan Post Bank ATM, the two networks that reliably accept foreign-issued Visa, Mastercard and other overseas cards.

The JR Pass roughly doubled in price and no longer pays off for most trips

The nationwide Japan Rail Pass underwent a price increase of about 70% on October 1, 2023, pushing the 7-day ordinary pass to 50,000 yen, with 14-day at 80,000 yen and 21-day at 100,000 yen. For a typical Tokyo-Kyoto-Osaka loop it now costs more than buying individual Shinkansen tickets, so unless you are crossing the whole country it usually does not pay off. Run your exact route through a rail-pass calculator before buying.

Uber in Japan just calls you a regular taxi, and GO is what locals actually use

There is no cheap UberX in most of Japan. Uber works, but it partners with local taxi operators rather than offering private-car rides, so you pay metered taxi fares.

The app locals overwhelmingly use is GO, which holds roughly an 80% share of taxi-app usage time and covers nearly the whole country. DiDi is a useful third option for discounts, having operated since 2018 in regions like Kansai, Kyushu and Hokkaido.

Tipping is not a thing, and trying to do it causes confusion

Unlike the US, tipping is not customary or expected anywhere in Japan, including restaurants, taxis and hotels, and attempting it usually just creates polite confusion. Staff often literally cannot accept the money because it is not built into their pay or tax system, and may chase you down the street to return change you left behind. Good service is the baseline, not something you pay extra for.

Public bins are rare and eating while walking is frowned upon

Japan removed most public trash bins decades ago, so you are expected to carry your rubbish until you find one, usually back at a convenience store or your hotel. Eating or drinking while walking is also considered impolite; locals typically finish a snack standing right outside the shop that sold it. Convenience stores and vending-machine clusters are your best bet for both a bin and a place to consume what you just bought.

The escalator-standing side flips between Tokyo and Osaka

On escalators you stand to one side and leave the other clear for people walking, but which side depends on the city: in Tokyo you stand on the left, while in Osaka you stand on the right. Get it wrong and you will quietly block a commuter rushing past. The same keep-to-one-side logic applies on station stairs and busy walkways.

How To Travel Around Japan

Buy a Suica Card Before You Do Anything Else

Get a Suica or Pasmo IC card the moment you arrive and you can stop thinking about train tickets entirely. You tap on entering the gate and tap off when you leave, and the fare is calculated automatically; the same card works on virtually all trains, subways and buses, plus convenience stores and vending machines.

Crucially the IC cards are interoperable across regions, so a Suica bought in Tokyo also works on the ICOCA network in Kyoto and Osaka and the SUGOCA network in Fukuoka, as Rakuten Travel’s Suica guide lays out. The one limit is that you cannot tap from one regional area straight into another, and the card does not cover Shinkansen or limited-express surcharges.

Don’t Trust Google Maps for Japanese Trains

For routing, do not rely on Google Maps alone. Google Maps is excellent for transit directions in Japan but, unlike most countries, it does not work offline here, so a working eSIM matters more than usual. Dedicated rail apps are often better for trains: Jorudan’s Japan Transit Planner is the most-downloaded navigation app in Japan, supports 13 languages including English and works offline, while Japan Travel by NAVITIME is built for tourists and can filter routes by whether you hold a rail pass, plus handle buses, taxis and expressway tolls.

The Shinkansen: Is the JR Pass Still Worth It?

The Shinkansen (bullet train) is the backbone of intercity travel, and you should reserve a seat for popular routes rather than relying on the limited non-reserved cars, especially around holidays. Since the Japan Rail Pass jumped about 70% in October 2023, most travellers doing a simple Tokyo-Kyoto-Osaka trip are better off buying individual tickets than buying the pass. Mobile coverage along the main Tokaido line between Tokyo and Osaka is strong 4G the whole way, dropping only briefly in tunnels and reconnecting on its own, so you can navigate and work as you travel.

Money: How Payments Actually Work

Cities Take Cards, the Countryside Wants Cash

Japan has modernised fast, and in cities contactless cards, Apple Pay, Google Pay and IC cards are accepted almost everywhere, but the country is still notably cash-heavy the moment you step off the main drag. Small individually run restaurants, older shops, market stalls, shrines and temple offering boxes are routinely cash-only. The safe habit is to always carry around 10,000 yen in cash as backup even on days you expect to pay by card.

Get Yen at 7-Eleven, Skip the Bank

When you need more yen, skip the bank counter and use a convenience store. 7-Eleven’s Seven Bank ATMs and Japan Post Bank ATMs are the two networks that reliably accept foreign-issued Visa, Mastercard, Amex and other overseas cards, operate in English, and are open long hours.

Many other domestic bank ATMs simply reject foreign cards, so these two are the ones to look for. Note that some machines push you toward withdrawing 10,000 yen or more at a time, and a small per-transaction ATM fee usually applies.

Two Card Habits That Save You Real Money

Two payment-card habits save real money and hassle. First, when an ATM or card reader offers to charge you in your home currency rather than yen, always decline and choose to be charged in yen to avoid inflated dynamic-currency-conversion rates. Second, remember a physical Suica can only be reloaded with cash; if you want to top up your transit balance with a credit card, you need the Suica inside Apple Wallet on an iPhone, per Rakuten Travel’s Suica guide.

How Much Data You Actually Need

The biggest mistake travellers make is underestimating the amount of data they need, then burning through a 1GB plan before lunch on day one. Here is what real activities consume per hour:

Phone Numbers and SMS

Most travel eSIMs for Japan are data-only, meaning you get mobile internet but no Japanese phone number for calls or SMS. In practice this is rarely a problem because you make calls and send messages over the internet instead: use LINE, which around 78% of Japan’s population uses, plus WhatsApp, FaceTime or Google Meet for everyone back home.

If you need to receive bank or app two-factor-authentication codes by SMS, the cleanest setup is dual-SIM: keep your home SIM active in a second slot purely to receive texts while your eSIM carries the data, or use a virtual number from a service such as Wise or Revolut. For genuine emergencies, Japan does not use 911; dial 110 for police and 119 for fire or ambulance, both free from any phone, 24 hours a day.

Emergency calls to 110 and 119 generally connect even on a data-only eSIM as long as your phone can reach any network.

Where You Will Actually Use Your eSIM

• Tokyoconstant real-time navigation across the world’s busiest rail network using Google Maps, which crucially does not work offline in Japan, plus topping up your Apple Wallet Suica on the move; coverage is full 5G across all 23 wards.
• Osakalive restaurant hunting on Tabelog around Dotonbori and Namba and hailing taxis with GO or DiDi late at night; remember the escalator-standing side flips to the right here versus the left in Tokyo, a detail worth checking on your phone.
• Kyotopulling up temple opening hours, bus routes and Google Translate for menus while your Tokyo-bought Suica works seamlessly on the local ICOCA network; signal is strong in the city centre and around the major shrines.
• Mount Fuji / Hakonemaps and weather checks in the mountains, where NTT Docomo has the strongest signal and coverage can weaken between the climbing-trail stations, so an eSIM riding Docomo is the safest bet.
• Hokkaido or Okinawaoffline-map downloads plus a Docomo-based eSIM matter most here, because while main islands and towns have good 4G, Docomo has the best coverage on Okinawa’s outer islands and rural Hokkaido roads.
• Shinkansen between citiesstaying online while travelling at speed; the Tokyo-Osaka Tokaido line has strong 4G throughout with only brief tunnel interruptions that reconnect automatically, so you can work, stream and navigate the whole way.
