I would like to know if there are other ways to say "at least~" (context below), along with the relevant nuances of each way.
This is for a piece of writing I'm doing where for the sake of style I want to avoid using the same phrase too many times. That said, please do include answers that may only be suitable for speech or conversation.
I am referring to "at least~" as used in the following context:
It looks like I won't be able to return to Japan for at least 6 months
(in other words I'm not looking for answers referring to phrases like せめて〜, which translates to a different meaning of the English phrase "at least")
