It is a common practice that the embassy will not divulge the reason why your visa is denied, especially going to countries with strict immigration policy. The embassy however will only show the criteria http://www.mofa.go.jp/j_info/visit/visa/procedure/issuance.html and ofcourse one should always follow that. I know that its a case to case basis for each individual's situation why they would be issued a visa or not. I was denied a visa back in August 2014 from Philippines, my purpose is to just visit my relative there for atleast 2 weeks or anything . I assume that i met all initial requirements because the agency had accepted it. My issue is, what are the tips i should take into consider or suggestion to have a greater chance of my visa to be approved.
I just think the following are some reason why it was not approved.
-I have an exit/re-entry visa from Saudi for 75 days before going back.
-I didn't include a statement of financial capacity because when my sister invited automatically i will stay in her house and she will take care of my expenses when i go there.
-Does including photo of you and your sister together back when you are younger will help? To prove that you are indeed related.
