random thought- is it harder for a japanese native speaker to learn english, or for an english native speaker to learn japanese?

i know this isn’t necessarily japanese studies related but i think about this all the time. the two languages have such drastically different ways of thinking and speaking (in terms of grammatical order but also usage of negatives vs positivists, inquiring, giving advice, honorifics vs. non honorifics, etc) that i always wonder which mindset is “easier” to adopt, when coming from the other. if that’s even true! they might be equally difficult to learn.

i’m an english native speaker learning japanese, so i’m curious to hear others’ thoughts on this question
