How many kanji per day: the 5, 10, 15, 20 rates, the review-load curve that peaks at weeks 4 to 6, the three-block schedule, and the burnout signature.
Balancing Japanese skills the right way: per-level ratios for listening, reading, speaking, and writing from N5 to N1, plus the variables that override them.
Build a personal Japanese content library: a system to curate, rank by learning yield, and rotate podcasts, books, anime, and news so you never stall.
Critical period vs. adult learners: what research really shows about learning Japanese after childhood, broken down by pronunciation, grammar, and vocabulary.
Finding i+1 input at each Japanese level: a sourcing map of graded readers, podcasts, Satori, and native material for N5 to N1, plus the valley fix.
Habit stacking for Japanese wires study into habits you already have. Get the formula, proven Anki, listening, and journaling stacks, and how to scale.
Hours per day vs. the marathon for Japanese study: why daily consistency beats weekend bursts for SRS, when burst-mode works, and the no-zero-days rule.
Build a Japanese study plan from four inputs: level, target, weekly hours, and skill priorities, with default allocations and a monthly review.
How to learn kanji, decided by camp: kanji-meaning-first (Heisig), radical to kanji to vocab SRS (WaniKani), or kanji-via-context, with a selection rubric.
How to make mnemonics for kanji that stick: the four principles, four story templates, the reading layer, and when curated banks beat self-authored stories.
What is kanji.koohii: the community story bank for Heisig RTK, how its keyword-to-character SRS works, the best-rated story filter, and Anki hand-off.
Comprehensible input is Krashen's idea that we acquire language by understanding i+1 messages: what research backs, what it misses, how to use it for Japanese.
Learning kanji through vocabulary explained: the AJATT and Refold case for kanji-in-context, the vocab-deck workflow, and trade-offs vs. Heisig and WaniKani.
Pure input vs. structured study: the recommended time split at each JLPT level, why N5 stays structure-heavy, and why grammar still earns a slice at N2+.
A primer on second-language acquisition for Japanese learners: what Krashen, Swain, Long, and Ellis got right, why input matters, and which claims fail.
What order should I learn kanji in? School grade, corpus frequency, and Heisig-style component order compared, with a decision rule and tool list.
Swain's output hypothesis explains why input alone stalls production. See the three functions of output and why Japanese keigo and particles reward speaking.
The comprehension threshold tells you how easy Japanese input should be: aim for 95 to 98 percent, the research-backed band for painless reading and listening.
The Heisig method for kanji explained: how Remembering the Kanji uses primitives, keywords, and stories, the 3-month timeline, and who it actually fits.
The interaction hypothesis explains why conversation drives language learning: negotiation of meaning, pushed output, and how tutors and exchanges deliver it.
How to measure Japanese progress with metrics that work: hours invested, deck size, mock-test scores, reading speed, plus what to stop tracking.
Is WaniKani worth it? How the radical, kanji, and vocabulary SRS pipeline drives the 60-level path, the ~20-item daily load, and who the method fits.
