Kyoto Immigration Office
So a few countries are allowed to extend their 90 day tourist visas for another 90 days, I'm from one of these countries. There is very little information available online on how to do this. I'm seeing a Japanese girl and we are not ready for a spouse visa, and would like to travel more for a few months to see how we get on. She doesn't get much holidays, so her coming to my country is impractical. So we can really only travel together on weekends, so 90 days hasn't been that much time of being together 24/7 as I don't stay at her place. Official Japanese site says to just apply at the closest immigration office, and there is one in Kyoto.
I'm wondering if anyone has any experience of doing this? Looking at the Google reviews for the office there are mixed reviews, though most people seem to be extending long term visas and don't mention the one I want specifically. I'm wondering with overtourism complaints by locals are the staff here a bit hostile to such requests. Or if people know how they are in general that would be great. Some old reviews say there is no English speakers so maybe I'd need to bring a translator with me? as in a Japanese speaker not just an app.
