In addition to a valid passport, some foreign nationals are required to obtain a visa, issued by the Japanese Embassy or Consulate in your country, to enter Japan.
In case it's uncertain whether the visa is necessary, or if you need to know details of the procedures, please visit the website of the Ministry of Foreign Affairs of Japan or contact the Japanese Embassy or Consulate in your country, since required steps to obtain visas vary from country to country.
