Citizens of 62 countries and territories, including most Western nations, can obtain landing permission on arrival without a visa. This is usually good for a stay of up to 90 days, although certain European nationalities and Mexicans are permitted to stay for 180 days if they note a longer stay upon entry. All other nationalities must obtain a "temporary visitor" visa prior to arrival, which is generally good for a stay of 90 days. The Ministry of Foreign Affairs maintains an online Guide to Japanese Visas. Note that no visa is required for a same-day transit between international flights at the same airport, so long as you do not leave the secured area.
All foreigners (except those on government business and certain permanent residents) at the age of 16 and over are electronically fingerprinted and photographed as part of immigration entry procedures. This may be followed by a short interview conducted by the immigration officer. Entry will be denied if any of these procedures are refused.
A customs issue that trips up some unwary travellers is that some over-the-counter medications, notably pseudoephedrine (Actifed, Sudafed, Vicks inhalers) and codeine (some cough medications) are prohibited in Japan. Some prescription medicines (mostly strong painkillers) are also banned even if you have a prescription unless you specifically apply for permission in advance. Go to [4] for more information. You may also require permission in order to import drug-filled syringes, such as Epi Pens and the like. Ignorance is not considered an excuse, and you can expect to be jailed and deported if caught. See Japan Customs for details, or check with the nearest Japanese embassy or consulate.
By plane
Most intercontinental flights arrive at either Narita Airport (NRT) near Tokyo or Kansai Airport (KIX) near Osaka; a smaller number use Chubu International Airport (NGO) near Nagoya. All three are significant distances from their respective city centers, but are linked to regional rail networks and also have numerous bus services to nearby destinations. Other international airports include Hiroshima (HIJ), Fukuoka (FUK) and Sapporo New Chitose (CTS). Tokyo's other airport, Haneda Airport (HND), more formally the Tokyo International Airport is the busiest in Asia but primarily serves domestic flights; the only international flights are shuttle services to and from Seoul-Gimpo, Shanghai-Hongqiao and Hong Kong.
Just about every sizable city has an airport, though most only offer domestic flights and a few services to China and Korea. A popular alternative for travellers to these cities is to fly via Seoul on Korean Air or Asiana Airlines: this can even be cheaper than connecting in Japan.
Both Narita and Kansai airports are generally easy to get through and not particularly crowded assuming you avoid the main holiday periods - namely New Year's (end of December - beginning of January), Golden Week (end of April - beginning of May), and Obon (Mid-August), when things are more hectic and expensive.
Japan's two major airlines are Japan Airlines (JAL) and All Nippon Airways (ANA). Northwest Airlines and United Airlines also operate sizable hubs at Narita, with flights to many destinations in the US and Asia.
By boat
There are a number of international ferries to Japan. Except for the ferries from Busan to Fukuoka and Shimonoseki, these are generally uncompetitive with discounted air tickets, as prices are high, schedules infrequent (and unreliable) and travel times long. In roughly descending order of practicality:
Korea
* Busan-Fukuoka: JR Kyushu Ferry, 092-281-2315 (Japan) or 051-469-0778 (Korea), operates hydrofoil service several times each day, taking about 3.5 hours and costing ¥13,000 one way. Camelia Line, 092-262-2323 (Japan) or 051-466-7799 (Korea), operates a ferry which takes about 8 hours and starts at ¥9000; if overnight, it may stop and wait in front of Busan Port in the morning until Korean Immigration opens.
* Busan-Shimonoseki: Kanbu Ferry, 0832-24-3000 (Japan) or 051-464-2700 (Korea), daily service. 13.5 hours; ¥9000+.
* Busan-Osaka: Barnstar Line, 06-6271-8830 (Japan) or 051-469-6131 (Korea), offers thrice weekly service. 18 hours; ¥13,700+.
China
* Shanghai-Osaka/Kobe: Japan-China Ferry, 078-321-5791 (Japan) or 021-6326-4357 (China), thrice weekly service. 45 hours; ¥20,000+.
* Tianjin-Kobe: China Express Line, 03-3537-3107 (Japan) or 022-2420-5777 (China), weekly service. 50 hours; ¥22,000+.
* Qingdao-Shimonoseki: Orient Ferry, 0832-32-6615 (Japan) or 0532-8387-1160 (China), thrice weekly service. 38 hours, ¥15,000+.
Russia
* Sakhalin-Wakkanai: Heartland Ferry. 5.5 hours; ¥21,000+. Service is suspended December-April due to sea ice.
* Vladivostok-Takaoka (Fushiki): Far East Shipping Co c/o United Orient Shipping, 03-5640-3901 (Tokyo), roughly weekly. 42 hours; US$320+.

Getting Around Japan
Japan has one of the world's best transport systems, and getting around is usually a breeze, with the train being overwhelmingly the popular option. Although traveling around Japan is expensive when compared to other Asian countries, there are a variety of passes that can be used to limit the damage.
For sorting through transport schedules and fares, Hitachi's Hyperdia [5] is an invaluable companion, with versions available for Windows and PalmOS, and is also usable online [6]. Jorudan and NTT Townpage both provide a useful English-language web versions. The paper version of this is the Daijikokuhyō (大時刻表), a phonebook-sized tome available for browsing in every train station and most hotels, but it's a little challenging to use as the content is entirely in microscopic Japanese. A lighter version that just includes limited express, sleeper and bullet trains (shinkansen) is available from the Japan National Tourist Organization's [7] overseas offices, or the same schedules are available for download at the J.R. website [8]
In Japanese cities, a place's address is useful for mail, but it's nearly useless for actually getting there. Most places are described in terms of the walking distance from the nearest train station, and relative to local landmarks. Business cards very often have little maps printed on the back to make navigation easier (at least if you can read Japanese). In addition, many train stations have maps of the local area that can help you find a destination if it is reasonably close to the station.

By railJapan's railways are fast, highly efficient and cover the majority of the country, making this the transport mode of choice for most visitors. The first and most confusing aspect of Japan's railway system (especially within large cities like
Tokyo) that you will encounter is the overlap of several private railway networks with the JR network. Tokyo also has two separate metro systems to add to the confusion. Being aware of this one fact will substantially reduce the confusion you experience trying to understand railway maps and find your way around.
JR network
The JR network is extensive as one would expect from what used to be the national rail system (now privately owned and split into regional companies). The JR group operates the Shinkansen lines, as well as a multitude of regional and urban mass transit lines. In the countryside the group companies also run bus services to connect places that don't have a rail service. However, the JR network is not a monopoly and particularly within major conurbations there are other private rail networks.
Interestingly, people refer to JR in Japanese by its English initials, "Jay-Arru." Hopefully even non-English speakers can help you find a station if you ask.

Train typesJR pioneered the famous Bullet Train, known in Japanese as Shinkansen (新幹線), and with speeds nudging 300 kilometers per hour (360 km/h in the near future), these remain the fastest way to travel around the country. Note that Shinkansen do not run at night, and eg. the last departures from Tokyo towards Kyoto and Osaka are around 9 PM.
The most important, most-travelled shinkansen route in the country is the Tokaido Shinkansen, operated by JR Central, which links Tokyo with Nagoya, Kyoto and Osaka. This line continues past Osaka as the San'yo Shinkansen, operated by JR West. Trains on the San'yo reach all the way to Fukuoka's Hakata station on the island of Kyushu, with stops at cities such as Okayama and Hiroshima.
On the Tokaido and San'yo Shinkansen, there are three types of services, reflecting the number of stops that the train makes:
Nozomi (のぞみ)
Nozomi is the fastest service, and is the primary service that runs through both the Tokaido and San'yo Shinkansen lines, though some other Nozomi trains run only between Tokyo and Osaka. A one-seat journey on the Nozomi from Tokyo to Hakata takes five hours. Seat reservations are required for all but three cars on the train. A small surcharge on top of the Shinkansen fare is required. Most importantly for tourists, the Japan Rail Pass is NOT valid on Nozomi trains.
Hikari (ひかり)Hikari is the next fastest service, but the fastest that is valid with the Japan Rail Pass. On the Tokaido Shinkansen, there are usually two trains per hour which depart from Tokyo. One train terminates in Osaka, and the other continues on the San'yo Shinkansen, terminating in Okayama. Separate Hikari services, known as the Hikari Rail Star (ひかりレールスター), operate on the San'yo route from Osaka to Hakata. Therefore, a Japan Rail Pass user will have to switch once in order to cover a journey such as Tokyo to Hiroshima. In most instances the best location to switch between Hikari trains is either at Shin-Kobe or Himeji station, since trains arrive on the same track.Kodama (こだま)The Kodama service, also valid under the Japan Rail Pass, is the all-stations service which stops at every shinkansen station on the route. Tokaido Shinkansen Kodama services generally run from Tokyo to Osaka, or Tokyo to Nagoya. Separate all-station Kodama services run on the San'yo Shinkansen. While Tokaido Kodama trains operate a full 16-car consist, San'yo Kodamas can operate with 16, 8, 6 or even 4-car trains, so check the signs on the platform for your proper boarding location. Other JR services, particularly suburban ones, use the following generic labels:
Regular (普通 futsū, 各停 kakutei or 各駅 kakueki) - local service, stops at every station
Rapid (快速 kaisoku) - skips approximately 2 out of 3 stops, no surcharge
Express (急行 kyūkō) - skips approximately 2 out of 3 stops, requires a surcharge
Liner (ライナー rainaa) - skips approximately 2 out of 3 kyuko stops, requires a surcharge
Limited Express (特急 tokkyū) - skips approximately 2 out of 3 kyuko stops, requires a surcharge and usually a reserved seat as well
Express services may offer first-class Green Car seats. Given that the surcharge of almost 50% gets you little more than a bit of extra leg room, most passengers opt for regular seats. However, if you really need to ride a particular train for which the regular seats are full, the Green Car is an alternative. The JR pass is available in two types "Ordinary", which you will have to pay the surcharge to use the Green Car, and "Green", which includes Green Car seats at no additional charge.
On N700 Series bullet trains (Tokaido and San'yo) and 8-car 500 Series bullet trains (San'yo only), smoking is not permitted except in a designated smoking room located between cars.
By planeTokyo's Narita Airport handles a few domestic flights, but most domestic flights leave from Haneda (HND) to the south of the city. Similarly, while there are some domestic flights from Kansai International Airport, more use Itami (ITM) to the north of Osaka, and Kobe's airport also fields some flights. Narita to Haneda or Kansai to Itami is quite a trek, so allow at least three and preferably four hours to transfer. Chubu, on the other hand, has many domestic flights and was built from the ground up for easy interchange.
List prices for domestic flights are very expensive, but significant discounts are available if purchased in advance. Both of Japan's largest carriers, Japan Airlines (JAL, 日本航空 Nihon Kōkū, [11]) and All Nippon Airways (ANA, 全日空 Zennikkū, [12]) offer "Visit Japan" fares where the purchaser of an international return ticket to Japan can fly a number of domestic segments anywhere in the country for only about ¥10,000 (plus tax) each. These are a particularly good deal for travel to Hokkaido or the remote southern islands of Okinawa. Some blackout periods or other restrictions during peak travel seasons may apply.
The low-cost carrier concept has yet to make significant inroads into Japan, but Air DO ([13]) provides a little much-needed competition between Tokyo and Hokkaido, while Skymark Airlines ([14]) and StarFlyer ([15]) serve Tokyo, Osaka and Kyushu. Usually these airlines offer lower walk-up fares than the majors but are not as competitive for advance-purchase discounted tickets.
ANA, JAL, and their subsidiaries offer a special standby card, the Skymate Card, to young passengers (up to the age of 22). With the card, passengers can fly standby at half of the full published fare, which is usually less than the equivalent express train fare. The card can be obtained from any JAL or ANA ticket counter with a passport-sized photo and a one-time fee of ¥1000
By boat
Given that Japan is an island nation, boats are a surprisingly uncommon means of transport, as all the major islands are linked together by bridges and tunnels. While there are some long-distance ferries linking Okinawa and Hokkaido to the mainland, the fares are usually more expensive than discounted airline tickets and pretty much the sole advantage is that you can take your car with you.
For some smaller islands, however, boats may well be the only practical option. Hovercrafts and jet ferries are fast but expensive, with prices varying between ¥2000-5000 for an hour-long trip. Slow cargo boats are more affordable, a rule of thumb being ¥1000 per hour in second class, but departures are infrequent. There are also some inexpensive and convenient short-distance intercity ferries such as the Aomori-Hakodate ferry.
These boats are typically divided into classes, where second class (２等 nitō) is just a giant expanse of tatami mat, first class (１等 ittō) gets you a comfy chair in large shared room and only special class (特等 tokutō) gets you a private cabin. Vending machines and simple restaurant fare are typically available on board, but on longer trips (particularly in second class) the primary means of entertainment is alcoholic — this can be fun if you're invited in, but less so if you're trying to sleep.

By busHighway buses
Long-distance highway buses (高速バス kōsoku basu; ハイウェイバス haiwei basu) serve many of the inter-city routes covered by trains at significantly lower prices, but take much longer than the Shinkansen. Especially on the route between Tokyo and Kyoto-Osaka-Kobe triangle the high competition broke down the prices: as low as ¥3500 one-way. There is a multitude of operators, including Star Express, Kansai Bus [16] as well as companies of the JR group.
Note that your JR Rail Pass may be valid for JR buses (although choosing the bus instead of the Shinkansen or any Express train for the same trip would be a very akward choice in terms of comfort and speed).
Many of these are overnight runs (夜行バス yakō basu) which allows you to save on a night's accommodation. It may be worth it to pay a premium to get a better seat; remember that it's less fun to sightsee after a sleepless night. Look out for ３列シート sanretsu shiito, meaning there are only three seats per row instead of four. Intercity buses usually have significantly less legroom than intercity trains, so passengers over about 175cm may be uncomfortable.
Like their railroad counterparts, a few overnight buses can only be used by women (an example is the Ladies Dream Osaka bus service between Tokyo and Osaka).

Local busesYou won't need to use local buses (路線バス rosen basu) much in the major cities, but they're common in smaller towns and the idiosyncratic payment system is worth a mention. On most buses, you're expected to board from the back and grab a little numbered slip as you enter, often just a white piece of paper automatically stamped by the dispenser as you pull it. In the front of the bus, above the driver, is an electronic board displaying numbers and prices below, which march inexorably higher as the bus moves on. When it's time to get off, you press the stop button, match your numbered slip to the electronic board's current price, deposit the slip and corresponding payment in the fare machine next to the driver, then exit through the front door. Note that you must pay the exact fare: to facilitate this, the machine nearly always has bill exchanger built in, which will eat ¥1,000 bills and spew out ¥1,000 worth of coins in exchange. If you're short on change, it's best to exchange before it's time to get off.
Increasingly, buses accept smartcards such as PASMO and Suica - you will need to tap your card against a scanner by the entrance (usually above the ticket dispenser) and then again using the scanner next to the fare machine by the driver when you exit. If you fail to 'tap on' when boarding, you will be charged the maximum fare when alighting.
The electronic board almost always includes a display and recorded voice announcements of the next stop — usually only in Japanese, although some cities (like Kyoto) make a welcome exception. However, if asked most drivers will be glad to tell you when you've reached your destination.
By taxiYou will find taxis everywhere in Japan, not only in the city, but also in the country. Taxis are clean and completely safe, though a bit expensive: starting fees are usually in the ¥640-660 range and the meter ticks up frantically after the first 2 kilometers or so. But sometimes, they're the only way to get where you're going. Taxi meters are strictly regulated and clearly visible to the passenger. If you're not sure if you have enough money for the trip, your driver may be able to guess the approximate cost of a trip beforehand. Taxi fares are also higher at night. Tipping is not customary and would most likely be refused.
In the city, you can hail a taxi just about anywhere, but outside train stations and other transfer points you should board at a taxi stand. (The taxi stand will usually either have a long line of patient passengers, or a long line of idle taxis.) If the destination is a well-known location, such as a hotel, train station, or public facility, the name alone should be enough. Note that extremely few taxi drivers can speak English, so carrying a pamphlet or card of your hotel or destination with the address on it can be very helpful.
An interesting feature of Japanese taxis is that the driver controls the opening and closing of the rear left passenger door. Try to avoid the habit of closing your door when you board the taxi. Taxi drivers also have a reputation for speeding and aggressive driving, but there are very few accidents involving bad drivers.
By car
Rental cars and driving in Japan are rare in or around the major cities, as public transport is generally excellent and gets you almost everywhere. In addition, the roads of major cities like Tokyo are plagued with massive traffic jams with parking expensive and difficult to find so driving there may be more of a hindrance than anything else. However many rural areas can really only be explored with your own transport, so driving should certainly not be dismissed out of hand, especially on the vast, sparsely populated island of Hokkaido.A international driver's license (or Japanese license) will be required if you wish to rent a car or drive in Japan, and must be carried at all times. Rental rates typically start from ¥6000 a day for the smallest car. Driving is on the left as normally found in UK/Australia/NZ/India/Singapore, opposite to continental Europe/USA/Canada. There is no "right turn on red" (or left turn, rather) rule in Japan. Almost all official directional signs are in both Japanese and English. Driving while drunk can result in fines of up to ¥500,000 and instant loss of licence, at above the official "drunk driving" blood-alcohol limit of 0.25mg. It's also an offence to "drive under the influence" with no set minimum that can be fined up to ¥300,000, with a suspension of license. Using a cell phone while driving without a hands-free kit can result in fines of up to ¥50,000.
