The Best Way to Learn Kanji (and Why Most Methods Fail)
Compare the major approaches to learning kanji — RTK, WaniKani, frequency-first, and reading-in-context — and find the one that actually fits adult learners.
Kanji is the part of Japanese that scares people off. 2,136 jōyō characters, each with multiple readings and meanings. Here's how the major methods compare, and what to actually do.
The four main approaches
1. Heisig (Remembering the Kanji / RTK)
Learn meaning + writing first, readings later. You blast through all 2,200 kanji in 3–6 months using mnemonics, then spend the next year attaching readings via reading.
Best for: Disciplined learners who tolerate delayed gratification. Worst for: Most people, because reading nothing for 6 months kills motivation.
2. WaniKani
SRS-based, teaches radicals → kanji → vocab in a fixed order. Excellent UX, takes 1.5–2 years if you stay consistent.
Best for: People who want a guided system and don't mind paying. Worst for: Learners who already know some kanji from Chinese — you'll be bored.
3. Frequency-first + SRS
Learn the top 1,000 kanji by frequency. They cover ~90% of newspaper text. Pair with reading real Japanese from day one.
Best for: Self-learners who want efficiency. Worst for: Total beginners who don't know what "top 1000" means yet.
4. Reading-in-context (organic)
Skip dedicated kanji study. Just read native Japanese constantly with instant lookups. Frequent kanji stick because you see them 50 times in a week.
Best for: People who hate flashcards and read a lot. Worst for: Learners who need to pass JLPT on a deadline.
What actually works for most people
A hybrid: WaniKani or frequency-SRS for the first ~500 kanji, then reading-in-context for the rest. The first 500 give you enough leverage to read graded content, and once you're reading daily, the next 1,500 stick through repeated exposure.
The mistake most learners make is treating kanji like a pre-requisite — "I'll start reading once I know 2000 kanji." You won't. You'll quit. Start reading at 300 kanji with a reader that handles lookups, like InputDojo, and let exposure do the rest of the work.
One uncomfortable truth
Writing kanji by hand is mostly obsolete unless you live in Japan and need to fill out paper forms. Modern Japanese is typed. Spending a year on stroke-order drilling pays off less than spending that year reading. Optimize for recognition, not production.

Frequently asked questions
How many kanji do I need to read Japanese?
The 2,136 jōyō kanji cover everyday adult text. The top 1,000 cover ~90% of newspaper content — enough to read with occasional lookups.
Should I learn kanji readings or meanings first?
For Western learners, meanings first (RTK-style) is faster early, but readings via vocab is more practical long-term. WaniKani and most modern systems do both in parallel.
Can I learn kanji without writing them?
Yes. Modern Japanese is typed, so recognition matters more than handwriting. Focus on reading; learn to write only if you'll live in Japan.
Stop reading about it. Start reading.
