I am planning to travel from Hong Kong to the US with an Indian passport. I have a US visa. I don't have a Japanese visa. The most convenient flight will have a long layover (almost 24 hours) in Japan with an airport change (HND to NRT). I would really like to maybe take a cab ride through Japan at most or just switch airports at least. Will not having a Japanese visa interfere with the airport switch?
And how hard would it be to get a 24 hour transit visa?
Edit: This trip will be in early August. Not sure if the covid situation is going to be as bad as it is now.
