There's no single "best" way to learn Japanese, but the research points to a few consistent levers: use active strategies (not just passive rote copying) for kanji, space out your vocabulary review and testing rather than cramming, pay deliberate attention to pitch accent early on since it's rarely taught but hard to fix later, and expect your existing language background and learning environment (classroom vs. self-study vs. study-abroad) to shape which strategies work best for you.
Answered for language learning in general. No specific language was set for this question, so the findings are drawn from general second-language research rather than one language’s literature.
Studies of learners of Japanese found that the kanji (Chinese-character) learning strategies people actually use cluster into a handful of types: reading practice, using context, breaking characters into parts (decomposition), rote copying/writing, listening, and memory tricks (mnemonics). Learners tend to settle into a strategy mix early and don't change it much over months.1,2
In plain terms
Learners whose native language uses an alphabet approach new Japanese characters differently than learners whose native language already uses Chinese-style characters, but the setting you're learning in (which country's classroom) can matter just as much as your native language background. In one comparison, Chinese-background learners studying in Australia used strategies similar to English-background classmates, not similar to what you'd expect just from their character experience — while learners in Sri Lanka showed a different pattern altogether.2,4,5
Learners whose first language uses an alphabet (rather than characters) tend to rely more on sound-based shortcuts and process kanji piece-by-piece rather than as whole shapes, and this leads to a distinctive error pattern (writing plausible-looking but incorrect fake characters). This gap versus native-speaking children narrows with more advanced study but doesn't disappear.5
A diary study comparing digital and printed flashcards for Japanese vocabulary found that digital flashcard users had shorter, more scattered study sessions and were more prone to distraction/technical issues, while printed flashcard users studied for steadier stretches with more repetitive practice but reported the kanji itself as the main sticking point.3
Example
Spacing out repeated exposure to a new word (rather than seeing it several times in one sitting) helps you consciously recall its meaning later, though it doesn't seem to speed up the kind of automatic, gut-level word sense that builds up regardless of spacing. Separately, a study of Japanese university students learning vocabulary found that quizzes which kept cycling in old words alongside new ones beat quizzes covering only the newest batch — but only once students had done enough practice repetitions, and the benefit was largest for lower-proficiency students.8,15
In plain terms
Example
Japanese uses 'pitch accent' — a rise and fall in pitch on specific syllables that changes a word's meaning — and multiple studies agree it is rarely explicitly taught, is hard for English-speaking learners to both hear and produce correctly, and doesn't reliably improve just from more classroom time or a study-abroad stay. Targeted practice (such as a dedicated pitch-accent training program, or training that pairs sound with a visual notation of the pitch pattern) produced measurable improvement where ordinary instruction did not.7,10,11,12,14
Example
Learners whose first language is a 'tonal' language (like Mandarin Chinese, which itself uses pitch to distinguish words) tend to have an edge in perceiving Japanese pitch accent over learners whose first language is not tonal (like Korean or English), even at advanced levels.7,11
In plain terms
A close study of Japanese classrooms found that learners actively sought out corrections and paid attention to feedback given to other students, not just feedback aimed directly at them, and gradually developed more appropriate ways of interacting through this classroom practice. Contrary to trends that de-emphasize teachers in favor of pair/group work, the study found the teacher's role in designing and framing peer activities was still critical to how much of the benefit students actually got.6
For advanced Chinese-speaking learners of Japanese, recognizing Japanese loanwords borrowed from English was easier when the word was more familiar and when its pronunciation sounded more similar to the English original; surrounding sentence context didn't reliably help and in some cases modeled worse alongside sound-similarity.9
A survey of Arabic-speaking anime fans found Japanese to be their most-desired third language to learn, and many engaged in informal learning (like watching anime) even without formal courses, suggesting media-driven immersion is a common and motivating entry point, though this source doesn't measure how much actual language proficiency resulted.13
