WHV for Japan – UK citizen

Hi guys,

I am from the UK but currently living in Australia. I am just wondering if anyone knows or has experience getting a WHV for Japan under these circumstances. I know you have to be residing in your home country. I will be going home for a little bit in September and plan to apply for the visa then. But i was planning on returning to Australia before flying to Japan. Does anyone know if you can do this (enter Japan but not from your home country? – if that makes sense?)

Thanks so much!
