>>77648845Japanese and English learning by each respective native learner is mutually difficult: Japanese is just as hard to learn for a native English speaker to learn as English is for a native Japanese speaker.
Consider the Foreign Service Institute's language ranking system, which rates languages in terms of how long in hours it usually takes English speakers to learn them to S-3/R-3 level proficiency.
Japanese is noted ad being the most difficult in the most difficult category that takes the longest. 88 weeks or 2200 hours of learning.
Japs require the same for English. Throughout their school life they might get 400 to 600 max of shitty learning no practice.
