I am a Filipino currently working here in Singapore (pass holder). I have a flight to Japan booked on July, 2015, but my port of origin will be in Philippines. I will be on a vacation in my home country on the same month so I decided to book my flight from there. However, one of the requirements in applying for a Japan visa here in SG is that the flight should depart and terminate here.
Does this mean that I need to apply my visa in the Japanese embassy in the Philippines? Or are there any additional documents I need to submit for me to be eligible to apply here despite my port of origin being in Philippines?
