For all nationalities not listed above, a visa must be obtained prior to travelling to Japan. If travelling on business or as a tourist a 'Temporary Visitor's Visa' can be issued at your local Japanese Embassy and usually gives you permission to stay in Japan for a period of up to 90 days. If you are travelling to Japan to work, find employment or live then it is best to call your local Japanese Embassy or Consulate and ask them the best procedure. almost 5 years ago
