To Work In Japan, a foreigner must receive a job offer from a guarantor in Japan, and then apply for a working visa at an embassy or consulate outside the country.
Working visas are valid for a period of 3 months to 5 years, and may be used to secure employment at any employer within the scope of activities designated on the visa "including employers other than the guarantor".
April marks the start of the year for schools and many companies in Japan — a month when many newcomers from overseas arrive in the country, just in time for the cherry blossom season.
If you are one of these new arrivals, a lot will be fresh and unfamiliar, and that, unfortunately, applies to the problems you may face as well as the positive aspects of your new life here. Even long-term residents are not immune to complications related to their visa status, work, money, family and so on.
The Japanese Ministry of Justice has decided that it is going to amend the rules for becoming a permanent resident in Japan to allow foreigners to apply for permanent residence after as little as one year in Japan. These rules will become effective as of the end of March 2017.
