visa app if not a resident in home country?

hi all, this is probably a pretty unique question so here is some context:

in august i went to japan for travel purposes and stayed until february this year, and returned to the uk where i was born and hold a british passport. i decided i wanted to try to stay and live in japan for longer and applied for a working holiday visa, but i was denied under the reasoning that i was not a uk resident because i was out of the country for more than three months.

i have now been offered a working visa sponsored by a language school in japan whom i disclosed my time in japan and time back in the uk to. so now i am preparing the documents for the coe and visa, but i�fm worried about being rejected due to this same reason of �gnot being a uk resident�h even though i am a citizen �c

so my question is if anyone knows if this will affect my application?

i was trying to read online about when you are considered a uk resident and i read one about living in the uk for 90 days consecutively (which i haven�ft right now, but will have by the time i�fm expected to start work in japan), or living in the uk for 183 days or more within the tax year (which i have). so im super confused and stressed out.

For a WHV there is a requirement that you must have lived in your home country for x time before you can apply. I guess it is to avoid to have people who do one WHV after another in different countries (not sure why Japan wants to avoid this).
For a normal working visa (and most/all? other visas) it is irrelevant where you lived so far.
