Traveling to Japan with another nationality requires a valid passport for the days to stay in Japan, and onward ticket to next destination or return ticket. Depending on the days of the stay and nationality, a Visa may be required. Because travel regulations and restrictions are complex and are subject to change with short notice, confirm the announcements by the Government of Japan.

A passport serves as proof of nationality and identification. Therefore, you will need to carry a valid passport for the duration of your stay and present it when requested upon entering Japan, during your stay, and upon departing Japan. When planning to travel Japan, be sure to make the passport arrangements required.
In addition to ensuring that the passport is valid for the duration of the stay, please note, that in some cases, people are unable to depart Japan if determined the passport is invalid. Requirements depend on nationality, the duration and purpose of the visit, so if your passport expires within a year, be sure to check the requirements.

Visa is for foreigners to apply before entering another country, to prove that the activities they intend to carry out in another country meet the conditions for landing, such as those that fall under one of the statuses of residence (excluding “short-term visitor” and “permanent resident”). In addition, the issued Certificate of Eligibility can be submitted and presented at the time of visa application or landing application at a diplomatic mission abroad to promptly obtain visa issuance or landing permission.
Any foreign visitor entering Japan must have a valid passport for the duration of the stay, and all visitors must comply with the conditions of the visas.
Regarding the visa conditions, please refer to the website of the Embassy or Consulate General of Japan.

Injuries and illnesses during your stay in Japan may incur in high medical expenses. Engagement with private medical insurance with sufficient coverage in case of emergencies is suggested.
