かは〜によって違(ちが)うDepends on, Changes depending on, Differ depending on

～かは～によって違(ちが)う is an expression in Japanese that appears quite complex at first, but is actually quite simple when broken down into its parts. かは is a combination of the case marking particle か in its role as a quotation, paired with the adverbial particle は, highlighting the topic of the sentence. Together these can be translated as 'whether (A)'.

によって違(ちが)う is made up of the case marking particle に (highlighting a location), the て form of よる (a う - Verb), followed by 違(ちが)う 'to differ', (another う - Verb).

All together, this can be translated as '(A) depends on (B)'. More accurately though, the meaning is 'whether (A) will differ depending on (B)'. かは is regularly used after an entire phrase, followed by a noun and then によって違(ちが)う.

Alternatively, かどうか may be used instead of かは. This changes the nuance from 'whether (A)', to 'whether or not (A)'. When translated directly, かどうか is quite similar to 'whether (A) or however'.

Finally, this expression may also be seen without 違(ちが)う. In a sentence like this, 'differs' is simply removed, becoming 'whether (A) will depend on (B)'. As conjugation between the verbs is no longer required, によって will become による.
