>The salaries in Japan arent great honestly, but mine, the quality of life and how far my money goes is so much better than if I lived back at the UK.

In a similar situation to you apparently. Every couple of years I'll take a look at UK as well as NZ and Aus (all places I can legally work) and Japan is still the better option. Even with the yen situation and despite all the doom and gloom others write online, life is still pretty nice here.
