Japanese transit cards and rail pass basics

Get a transit card first

In Japan's big cities, one rechargeable IC transit card gets you onto most trains, subways and buses. You no longer need to look up each fare on a route map and feed coins into a machine, which takes a lot of the strain out of the first day. The major regional cards are interoperable, so a card bought in one region works in most other big cities, and you can also use it to pay at convenience stores, vending machines and station lockers. You can buy a physical card from station machines or ticket offices, or add a transit card to your phone. There are also cards made for tourists; where they are sold, how long they last and whether the deposit is refunded may differ from regular cards, so check the conditions when you buy.

Ticket gates and low balances

At the gate, simply touch the card to the reader. You tap in and tap out, and the fare is calculated from both; if your balance is too low, the exit gate will close. Don't panic: use the fare adjustment machine near the gates to top up the shortfall and go through again. Many of these machines take cash only, so keep a little change on you. Buses work differently from region to region. In some places you board at the front and pay first; in others you board at the back, take a numbered ticket or tap your card, and pay at the front when you get off according to the fare display. On an unfamiliar bus, watch what the person in front of you does.

Where the card won't work

A transit card is not universal. Some rural railways and buses accept only cash or paper tickets. Even in big cities, if you cross the boundary of a card area and get off at a station in another area, the gate may not let you through. Show your card to station staff and they will settle the fare. Bullet trains and reserved-seat limited expresses usually cannot be boarded with a transit card alone, or need separate registration, so assume that long-distance journeys need their own tickets.

Types of rail pass

Japanese rail passes fall into three broad groups: nationwide passes for short-term foreign visitors that cover lines across the country for a set period, regional passes valid only within a particular area, and one-day tickets for unlimited rides on a city's subway or buses. Each pass differs in which companies and lines it covers, which train classes you can ride, who is eligible and how to buy it, and the rules change regularly. Even with the same pass, some high-speed trains may require a supplement or a separate ticket, so always confirm the coverage on the operator's official site before buying.

How to decide whether a pass pays off

The more you ride, the better a pass looks, but single tickets often work out cheaper for a given route. Instead of buying on instinct, work it out in this order.

• Decide which city you will travel between on each day
• Look up the regular fare for each leg with an official route search and add them up
• Compare with the pass price, adding any legs the pass does not cover
• If most trips are within one city, see whether a day ticket or a transit card is enough

Riding bullet trains and limited expresses

Long-distance fares are usually split into a basic fare ticket and a limited express ticket for the faster train. Seats are either reserved or non-reserved, where it is first come first served; on busy holidays and weekends the non-reserved cars fill up and you may have to stand. Some lines require passengers carrying luggage above a certain size to book a seat with an oversized baggage area in advance. The size limit and what happens if you don't book differ by line, so check before booking if you have a large suitcase. Trains leave exactly on time, so get to the platform with time to spare.

Finding your way in stations

Large stations in Tokyo or Osaka bring together lines run by several companies, each with its own gates even under the same station name. Many stations mark lines with a colour and a letter and each station with a number, so following the line code and number is faster than following station names. Exits are numbered too; knowing the exit nearest your destination saves long detours underground. When transferring to a line run by another company, you may need to pass through a dedicated transfer gate, and if you step outside, the fare may be calculated separately.

Common mistakes and cautions

City trains are extremely crowded during the weekday morning rush, so moving with large luggage is easier for everyone at other times. Some lines have women-only cars during rush hours, marked on the platform floor or the car itself. Avoid phone calls on board and keep your phone on silent. Some lines stop surprisingly early at night, which can leave you needing a taxi, so check the time of the last train in advance. Fares, pass prices and luggage rules change, so use the principles here and check the current numbers on the railway company's official site.
