A Japan visa is an official travel authorization required for foreign travellers visiting Japan for tourism, business, work, study, family visits, or transit. Applicants must submit their documents through the Japanese Embassy or Consulate, depending on nationality and purpose of travel. The process typically requires a valid passport, photographs, flight itinerary, hotel bookings, financial proof, and supporting documents such as invitation letters or company details. Tourist visas generally allow stays of up to 15–30 days, while work and student visas require additional approvals and long-term residence procedures. Japan has a structured and detailed verification process, making correct documentation essential for a smooth and timely visa approval.
