Frequently asked questions
What is hiragana?
Hiragana (ひらがな) is one of the two Japanese kana syllabaries. It has 46 basic characters plus dakuten (voiced) variants like ga, za, da, ba, handakuten (semi-voiced) variants like pa, and combination characters (yōon) like kya, sha, cha. Together these cover all the sounds used in native Japanese words. Moji Ninja lets you practise all of them.
What is katakana?
Katakana (カタカナ) is the second Japanese kana syllabary with 46 basic characters, plus dakuten, handakuten, combination, and extended characters for foreign sounds like fa, fi, va, vi, ti, di, che, she. It is used to write foreign loanwords, onomatopoeia, scientific terms, and for emphasis. Moji Ninja covers all standard and extended katakana.
Can I learn kanji with Moji Ninja?
Yes. Moji Ninja teaches the 284 kanji of JLPT N5 and N4 in 34 small themed sets, with stroke-order drawing and typed-answer reviews. Each kanji's meaning, reading and writing are reviewed separately with spaced repetition, and you learn the readings through real words. Every example word and sentence uses no kanji but the one you are learning, so you can read all of them as soon as you know it.
How long does it take to learn hiragana and katakana?
Many learners can memorise the 46 basic hiragana in 1–2 weeks and the 46 basic katakana in another 1–2 weeks. Dakuten, handakuten, and combination kana are easier to learn once you know the basics — typically another 1–2 weeks. Moji Ninja's spaced repetition, quizzes, typing drills, and stroke-order drawing accelerate the entire process.
What is the best way to learn kana?
The most effective approach combines recognition (quizzes), recall (typing the romaji from memory), and muscle memory (practising correct stroke order). Spaced repetition ensures you review characters just before you would forget them. Moji Ninja offers all of these methods in one free tool.
Is Moji Ninja free?
Yes, Moji Ninja is completely free with no sign-up required. It works in any modern browser, can be installed as a PWA for offline use, and has no ads or paywalls.
