>>83990309Language learning is widely, incredibly misunderstood. It requires far more individual approach than the education industry can handle.
It depends on both the specifics of the native/working language of the learner and that of the target language. Native English speakers are at a massive disadvantage when learning Japanese.
Japanese has more productive morphology, it's vastly more important to be comfortable with recognizing parts of speech in a sentence etc. Japanese absolutely requires you to get comfortable with its grammar (and I'm saying grammar rather in the Latin sense than the English sense) BEFORE you can start grinding vocabulary. It's the other way around with English where caveman-ing it in the beginning is the way to go, since it's almost analytic with its null derivation and other stuff and derivation and syntax only start matter at around the upper intermediate level.
The preferred method to learn Japanese is to get a personal tutor who's a confident to fluent speaker of your own native language and is actually versed in the underlying linguistics and essentially go through a very dry, technical phase where you learn all the grammatical concepts at the basis of Japanese. By around the N3 level you can start immersing, grinding kanji etc. but also you probably still wanna keep your tutor around to ask them questions that are hard to find answers to by yourself such as the intricacies of the stylistics (Japanese being a very stylistically stratified language) etc.
