Japanese Working Holiday Visa application (from Germany)

Hi everyone,

I’m currently preparing my WHV application from Germany and I have a couple of doubts about how to proceed:

1.I previously stayed in Japan for 5 weeks at a language school this year. Would mentioning this stay lower my chances of approval in any way? I heard about someone having some brief doubt about that for the same reason in a different Reddit post (they ended up getting the visa) but I’m kind of losing sleep over that.

2.I already have an apartment lined up for my WHV year. Should I mention this in my application? Or would it possibly even better my chances? My travel plan involves visiting many different regions across Japan, and I’m not sure if it would look inconsistent or unbelievable if I say I’ve secured one apartment for the year while also planning to travel around.

Any advice would be greatly appreciated
