About かどうか
かどうか is an expression in Japanese which combines the 'or' meaning of か, with the 'how' meaning of どう. (A) かどうか (B) is regularly translated as 'whether or not (A), (B)'.
To use かどうか, simply attach it to the end of any phrase that you want to express the 'or' use of か about, then add the (B) phrase.
Although 'whether or not' is the standard translation, the more literal translation of かどうか is 'if it's (A), or however it is, (B)'.

Considering this example sentence:
まだ日本に行けるかどうか分からない。
What tells me that the まだ connects with 分からない and not 行ける?
How would I express “I don’t know whether I can still go to Japan.”?

Hey @Isurandil492 !
To be honest, without context
まだ日本に行けるかどうか分からない。
can be understood as both
“I don’t know whether I can still go to Japan.” and " I still don’t know whether or not I can go to Japan."If one wants to be clear then we can move まだ and add some pauses:
私は日本に行けるかどうか、まだ分かりません。
" I still don’t know whether or not I can go to Japan."まだ日本に行けるかどうか、私は分かりません。
I don’t know whether I can still go to Japan.I hope it helps,
Cheers!
