Kanji & reading guide
How furigana, on’yomi and kun’yomi work—and how to use the clues without treating them as rigid rules.
Furigana
Furigana is the small kana printed above or beside kanji. It tells you how the whole written word is pronounced in this sentence.
学校
Word reading: がっこう
The furigana belongs to the complete word. It is the first thing to trust when reading the sentence aloud.
食べる
Word reading: たべる
The kana after the kanji is called okurigana. It often carries conjugation and is a strong clue that the reading is kun’yomi.
On’yomi and kun’yomi
On’yomi are sound-based readings that entered Japanese through Chinese vocabulary. Dictionaries and this portal normally display them in katakana.
Kun’yomi connect a kanji’s meaning to a native Japanese word. They are normally displayed in hiragana.
A kanji can have several readings. The correct one belongs to the word, not to the character in isolation. Hover a kanji in a sentence to see the exact word pronunciation first, then its common on- and kun-readings.
Useful rules of thumb
| Pattern | Likely reading | Example | Why |
|---|---|---|---|
| Two or more kanji together | Often on’yomi | 学校, 電車 | Many compounds were formed from Sino-Japanese vocabulary. |
| Kanji followed by okurigana | Often kun’yomi | 食べる, 新しい | The native stem is written with kanji and the changing ending stays in kana. |
| A kanji used as a standalone everyday word | Often kun’yomi | 山, 水 | Many basic native Japanese words are written with one kanji. |
| Fixed, irregular or mixed reading | Learn the whole word | 今日, 大丈夫 | Japanese contains exceptions, historical readings and mixed formations. |
How to study in this portal
- Try to read the kanji before looking at its furigana.
- Use the furigana to confirm the complete word.
- Hover the kanji and compare the word reading with its on- and kun-readings.
- Open Writing Studio and trace the same character.
- Remember the word as a unit; do not guess only from an isolated reading list.
About the N4 deck
The N4 switch contains original practice material built around everyday reading, listening and grammar patterns. It is N4-aligned rather than an official syllabus: the JLPT defines ability levels, but does not publish one mandatory public sentence, vocabulary or kanji list.
Less common technical terms stay in kana so the new kanji load remains gradual. N5 and N4 sentence progress is stored separately.

Your first week
The beginning alternates kana, useful Japanese, readable words and selected handwriting. You will hear genuine expressions before you are expected to read every symbol.
Review is automatic
Correct answers move an item forward. Missed answers return sooner. You do not need to choose a difficulty rating or manage intervals yourself.
Writing and accessibility
Required Path characters use bundled stroke-order templates and work offline. Draw with a finger, stylus or mouse. When precise drawing is difficult, choose Watch & confirm instead, view every stroke, then confirm that you followed the order.
Practice follows the Path
Kana, writing and other trainers reveal only material that has already appeared in your course. Locked destinations explain when they become available instead of opening an empty screen.
Frequently asked questions
Why can’t I open every trainer yet?
Early choices are intentionally limited so the next step stays clear. Features unlock as soon as their prerequisite material appears on the Path.
Do I need to finish handwriting perfectly?
No. The drawing score is deliberately forgiving, and the watch-and-confirm route is available for motor or input limitations.
Can I keep studying after the daily goal?
Yes. The goal is a suggested stopping point. Choose Continue whenever you would like another short block.
Can I replay the beginning?
Use Replay first sounds above. Your saved Path progress is not reset.
