I am traveling from India to USA on my company's official business. I am an Indian passport holder and have US business and tourist visa. On my return journey from San Francisco to India, I want to stop over at Tokyo for 4 days. Can I apply for transit visa to enter Japan for 4 days? The reason for this question is I am entering Japan while returning from USA to India and not while going to USA from India, so want to check if transit visa is still applicable in this case as I would be transiting back to my home country. The Japanese embassy website for India mentions just "foreign country visa" and "flight tickets" as requirement for transit visa so it is not very clear if it can be used only in one direction - from home country to foreign country or in any direction.
Any help will be appreciated.
