こんにちは! I’m Kenta. I know many people who sees kanji for the first time get intimidated by its unfamiliar structure compared to the latin alphabet, but you never have to learn alone. We’ll discover their radicals, practise their readings, and build your confidence one character at a time.
A short writing-system history
How kanji, hiragana, and katakana came together
1
Kanji arrived from China
Japan had a spoken language before it had a widely used native writing system. Chinese characters reached Japan through centuries of contact with the Asian mainland. Writers first used Classical Chinese, then adapted characters to record Japanese words and sounds.
2
Characters were also used for sound
One early method, now called man’yōgana, used kanji for their pronunciation rather than their meaning. It appears prominently in the eighth-century poetry collection Man’yōshū. This sound-based use became the foundation for both kana systems.
3
Hiragana grew from flowing forms
During the early Heian period, cursive handwritten forms of kanji used for sound became increasingly simplified. These rounded forms developed into hiragana, which became especially important for Japanese grammar and literature.
4
Katakana grew from character fragments
Scholars developed abbreviated marks from parts of kanji to annotate texts and indicate Japanese readings. Those angular shorthand forms developed into katakana, which later gained its modern roles for foreign words, scientific names, sound effects, and emphasis.
5
Modern Japanese uses all three
Today, kanji usually carry core meaning, hiragana handles many grammatical endings and native words, and katakana marks many borrowed or highlighted terms. They are complementary tools within one writing system—not three competing alphabets.
Learn the standard Jōyō kanji used in everyday Japanese, or study by JLPT or Kanji Kentei level.
Are there different standards for learning kanji?
Yes. Three useful ways to organise kanji study are the official Jōyō list, the proficiency levels associated with the JLPT, and the graded progression used by the Kanji Kentei.
Jōyō kanji
The Jōyō list contains 2,136 characters designated by the Japanese government for common use. Japanese schools teach them gradually across primary and secondary education.
JLPT kanji
The Japanese-Language Proficiency Test has five levels, from beginner N5 to advanced N1. Because the test does not publish official kanji lists, these groups are widely used community estimates.
Kanji Kentei (漢検)
Kanji Kentei has 12 grades, progressing from 80 beginner kanji at Grade 10 to roughly 6,000 at Grade 1. Kenta follows these proficiency ranges as an independent practice aid, not an official exam.
What is a radical?
A radical is a recognisable component inside a kanji. It can suggest part of the character’s meaning or provide a useful visual clue. If you recognise a shape but do not know the complete kanji, select it—or combine several radicals—to narrow the library to matching characters.

Your mastery journey
This belt exam covers every kanji in the level. A perfect score guarantees a rank-up. One to three mistakes earn a second chance with 10 new questions that mix in the kanji you missed.
1 · Choose a curriculum
Jōyō means everyday-use kanji: this course follows the kanji taught across Japanese primary and secondary school, arranged here as school Grades 1–9.
Independent practice aid: elementary levels follow Japanese school-grade coverage and Grade 2 covers all Jōyō kanji. Upper pools use frequency-ranked approximations to the published proficiency totals; this is not an official 漢検 exam simulator or affiliated with the Japan Kanji Aptitude Testing Foundation.

Follow the growing radicals
Grow a kanji one branch at a time.
Search all 6,359 kanji, then follow characters that contain the selected form as a component. Explore direct branches in manageable groups, including advanced kanji.
Try:
A component map, not an origin story: the tree recognizes both directly listed components and larger shapes reconstructed from the same smaller radicals. For example, it can connect 共 (together) to 供 (submit/offer), even when the source data lists 共 only through its inner shapes.

Kenta's practical tipHow to alphabetise Japanese books and gamesOpen
Japanese titles are ordered by their recorded pronunciation in the gojūon sequence—not by the shape, stroke count, or Unicode position of their kanji. Write a kana sorting form for every title before comparing them.
1
Write the official reading
Copy the title's furigana, publisher reading, or catalogue reading. Convert a kanji title such as 雨 to あめ. A kanji has several possible readings, so its printed shape alone cannot determine its place.
2
Normalize the script
For comparison, treat katakana as its hiragana equivalent: カ → か and ゲ → げ. Ignore spaces and ordinary punctuation unless your collection needs a special house rule.
3
Compare one mora at a time
Start with the first kana. If two titles match, compare their second kana, then their third, continuing until they differ. A shorter reading comes first when every sound up to its end is identical.

か き く け こ

Marks and smaller kana
゛ Voiced mark
Keep it with its base row and place the plain sound before the voiced sound: か before が; は before ば.
゜ Semi-voiced mark
In the は row, use the practical order は, ば, ぱ (and likewise ひ, び, ぴ).
Small ぁ・っ・ゃ
Compare them at the position of their full-size counterpart first. If two readings otherwise match, use small versus full size as a tie-breaker.
ー Long-vowel mark
Read it as the vowel prolonged by the previous katakana. For a hand-sorted shelf, write that vowel into your sorting form before comparing titles.
々・ゝ・ヽ Repetition
Expand the repeated kanji or kana to its spoken reading in your sorting form rather than sorting by the repetition mark itself.
Worked example: compare the readings, not the scripts雨あめ · ame→いぬinu→ゲームげーむ · gēmu→空そら · sora
For a personal shelf: write each title in hiragana on a temporary label, normalize the special marks using the rules above, and sort those labels from あ to ん. Large catalogues use formal collation standards and may differ in their final tie-break rules, so retain an institution's supplied reading when matching its catalogue.
