I tried to search in the previous posts but it's kinda unclear. I'm considering quitting my job and spend 6 months up to a few years in thailand/traveling. I CAN'T buy an elite visa but I have more than 500k in the bank. I thought of DTV but since I'm going to quit my job, I believe that my boss won't help me with this task. (I teach in person). I read about some folks applying to DTV for medical reasons and all they had to do is just showing the embassy they booked an appointment at a hospital and their bank account. Does that really work and how it works? I could eventually point out I need to do some dental crowns but not sure if that'd be enough. Do you guys have any advice?

So I have been living and working in Japan for around 15 years or so, but have never really needed to get my PR, so haven't gone down that route. I have a spouse visa though. Does anyone know if this is going to be good enough to apply for the DTV in Tokyo or is it strictly PR? Can anyone with experience please share their insights? I've read mixed reports, but mostly stating PR is a must. TIA!
