How often can you border bounce?

I’m currently on my second tourist visa, I would like to go to tokyo and back before I fly to cambodia to apply for DTV visa. Is this possible? Or will i get into trouble when coming back from tokyo amd having my third entry in the country.

Dutch(The Netherlands) passport.

I have a colleague that needs to fly from japan to Thailand for cancer treatment. I can get the visas but I can’t get the flight. Anyone has any ideas I would really appreciate it!

Hi there, I am currently in Tokyo (though a UK resident). I am visiting Thailand from 3rd April for 34 days and have a flight booked back home. Is it possible to get a tourist visa for more than 30 days? Can I get my visa at the Tokyo airport when I fly and how do I do this?

If it is not possible to get a visa for more than 30 days is my next choice to get a 30 day one and then extend it after 4 days, at the Bangkok bureau?

Many thanks!
