Entering Japan
All foreigners, including foreign residents, get fingerprinted and photographed upon entering Japan as a measure aimed at preventing terrorism. Excluded from this procedure are persons under the age of 16 and a few special groups, such as diplomats and visiting dignitaries.
All foreigners receive a status of residence when entering Japan. There are more than twenty statuses of residence, including "temporary visitor" for tourists, and a range of statuses for students, workers and relatives of Japanese nationals and residents.
Workers
Foreigners, who wish to work in Japan, need to get a work visa from a Japanese embassy or consulate outside of Japan in order to enter the country on a status of residence permitting work.
There are over a dozen such statuses of residence, each allowing the holder to work only in a specific professional field, for example, journalism, arts, research, education, engineering, entertainment, business management, international services, etc. If you change jobs while you are in Japan and your new job falls into a different professional field (e.g. from education to engineering), you will need to change your status of residence.
A university degree or considerable professional experience in the applicable field is required to qualify for a working visa. Most types of working visas also require you to have a prospective employer as a sponsor. Residence permission is granted in periods of 6 months or 1, 3 or 5 years and is extendable.
Spouses and Dependents
Foreigners, who are married to a Japanese national or to a permanent resident of Japan (see below), can obtain a spouse visa, which allows them to engage in any paid activity in Japan. Residence permission is granted in periods of 6 months or 1, 3 or 5 years and is extendable.
Spouses of foreigners, who are currently staying in Japan under a status of residence permitting work, can apply for a dependent visa. Residence permission is granted in periods of between 3 months and 5 years and is extendable. Dependents are not allowed to engage in any paid activities, unless they get permission from the immigration office. Even then, dependents may work only a set maximum number of hours per week.
Staying in Japan
Inside Japan, most immigration related matters, such as extending residence permission, changing status of residence or obtaining a re-entry permit, are handled by the Immigration Bureau (Nyukoku Kanrikyoku), which has branches across the country.
Alien registration
The Alien Registration system was discontinued on July 9, 2012. Instead, foreigners are now registered in the same residence system as Japanese nationals, and alien registration cards are replaced by residence cards (see below). Old alien registration cards can be used instead of a residence cards until they expire or until July 8, 2015, whichever comes first.
Residence Card
From July 9, 2012, all new foreign residents are issued a residence card upon initially entering Japan at Narita,Haneda, Kansai or Chubu Airports. New residents arriving through different ports can get their cards at their municipal offices. Existing residents may continue to use their alien registration cards instead of a residence card until their cards expire or until July 8, 2015, whichever comes first. At that time, their alien registration card will be replaced by a residence card.
The residence card is an important document required for opening a bank account, obtaining a cell phone, converting a drivers license and similar activities. It stores the holder's personal information, including the current address, the status of residence and period of stay. Foreign residents are required to carry their residence card with them at all times.
Extending residence permission
Most statuses of residence allow you to stay in Japan for a period between three months and five years. If you wish to stay longer, you must apply for an extension at an immigration bureau inside Japan before the expiry date of your current residence permission.
The application process is relatively simple, provided that you still fulfill the conditions for the specific status of residence. It typically takes a couple of days or weeks for the application to be processed, and you are allowed to remain in Japan during that time even if your previous residence permission expires in the meantime.
Changing status of residence
It is possible to change your status of residence (e.g. from temporary visitor to instructor or from student to engineer) at an immigration bureau inside Japan. You will have to provide similar documentation as you would have to when applying at an embassy or consulate outside of Japan.
Re-entry permits
Foreign residents, who wish to temporarily leave Japan for longer than a year, need to get a re-entry permit, otherwise, they lose their status of residence. Re-entry permits can be obtained at immigration offices in Japan. For absences of less than one year, re-entry permits are not required anymore as of July 9, 2012.
Permanent residence
Foreign residents who have shown good conduct and have sufficient assets or ability to make an independent living, can be granted permanent residence if they reside in Japan for typically ten or more consecutive years (less in case of spouses of Japanese nationals and people who have made significant contributions to Japanese society). Permanent residence status is indefinite and allows any paid activity.
Naturalization
Foreigners, who have resided in Japan for at least five consecutive years (less if married to a Japanese national), have shown good conduct, have never plotted against the Japanese government, have sufficient assets or ability to make an independent living and are willing to renounce any other citizenship held, can be granted Japanese citizenship.
