Does Japan impose layover restrictions for travellers from India to the USA?

Are there any restrictions for a layover in Japan when I am travelling to the U.S. from India?

I am cleared to travel to the U.S. but not sure about layover requirements for Japan.

The connecting flight will be in 4 hours after I land in Japan.

Best Answer

For the purposes of this answer I am assuming that you are:

travelling on a single ticket;
arrive and depart from the same airport (probably Narita) within the same calendar day; and
do not need to re-check your bags or pass immigration for any other reason.

In such cases, a transit visa or any other documentation was not required to transit Japan. This still holds true during the pandemic: as long as you are not entering Japan (i.e. passing immigration), the Japanese government imposes no restrictions.

In the words of Japan Air Lines from their website (select guests entering Japan and then scroll down):

Travelers who are not entering Japan and transferring directly to a third country by transit, are not required to submit any documents and undergo PCR tests.

However, the following cases require entry into Japan. Please be informed that foreign nationals arriving from prohibited countries will not be allowed to enter Japan.

Transferring between Tokyo International Airport (Haneda Airport) and Narita International Airport

Travelers with a connecting flight out of Narita International Airport the following day

So this itinerary is possible.
