Learn the First ~100 JLPT N5 Kanji with Visual Mnemonics
TL;DR: The JLPT N5 covers roughly 100 kanji. The fastest way to learn them is not rote copying but visual mnemonics: break each kanji into its radical parts, tie those parts into a vivid little story, then meet the kanji inside real vocabulary and review it on a spaced-repetition schedule.
How many kanji are at JLPT N5 (and beyond)?
The JLPT no longer publishes official kanji lists, but analysis of past exams gives a reliable community consensus. At N5 you need around 100 kanji and about 800 vocabulary words. That is genuinely achievable in a few weeks of steady study.
For perspective on what comes next:
| Level | Approx. kanji | Approx. vocabulary | What you can do |
|---|---|---|---|
| N5 | ~100 | ~800 | Read basic signs, simple sentences |
| N4 | (builds on N5) | ~1,500 | Handle everyday topics in plain text |
| N3 | (builds on N4) | ~3,000 | Read simplified news, follow daily conversation |
The takeaway: N5 kanji are a small, finite set. You are not facing 2,000 characters yet. You are facing about 100, and most of them are simple, concrete, and visual.
Why kanji are perfect for image-based memory
Kanji began as pictographs — drawings of real things. 木 was a tree. 山 was a mountain. 川 was a flowing river. Over centuries the drawings got stylized, but the visual logic is still there, and that is exactly what makes kanji friendly to image-based memory.
Two well-established findings explain why mnemonics beat brute repetition:
- The Picture Superiority Effect: we remember pictures far better than words alone.
- Paivio's Dual-Coding theory (1968): information encoded as both a verbal label and a mental image creates two retrieval paths instead of one.
A kanji is already a tiny picture. When you attach a deliberate mental image to its shape and meaning, you are dual-coding by design. This is the same principle behind the power of visual memory — your brain is built to hang on to pictures.
Radicals: the building blocks
The trick that makes mnemonics short is radicals — the recurring component parts that kanji are built from. There are 214 traditional radicals, but a small core set covers most common characters, so you learn them once and reuse them everywhere.
Two quick examples of radicals combining into meaning:
- 亻 (person) + 木 (tree) = 休 "rest" — a person leaning against a tree to rest.
- 日 (sun) + 月 (moon) = 明 "bright" — the sun and the moon together, doubly bright.
So the chain runs radicals → kanji → vocabulary: radicals are the bricks for kanji, kanji are the bricks for words. Once you know the bricks, every new kanji is a recombination of pieces you already recognize, not a wall of unfamiliar strokes.
A sample of N5 kanji with mnemonics
Here are several common N5 kanji broken into parts, with a mnemonic, the meaning, and a basic reading. Treat the stories as starters — the ones you invent stick best.
| Kanji | Meaning | Reading | Visual mnemonic |
|---|---|---|---|
| 一 | one | いち (ichi) | A single horizontal line — one stroke, one thing. |
| 木 | tree | き (ki) | A trunk with branches and roots spreading out. |
| 山 | mountain | やま (yama) | Three peaks rising side by side. |
| 川 | river | かわ (kawa) | Three lines flowing downstream. |
| 日 | sun / day | ひ (hi) | A window with the sun framed inside it. |
| 人 | person | ひと (hito) | A figure walking, two legs striding. |
| 休 | rest | やす(む) (yasu-mu) | A person (亻) resting against a tree (木). |
| 明 | bright | あか(るい) (aka-rui) | The sun (日) and moon (月) shining together. |
| 大 | big | おお(きい) (oo-kii) | A person stretching arms wide: "this big!" |
| 木 + 木 = 林 | woods | はやし (hayashi) | Two trees standing together make a small wood. |
See how 木 reappears in 休 and 林? That is the radical payoff. Learn one component and it pays dividends across many characters.
Pair kanji with vocabulary and spaced repetition
Kanji learned in isolation fade fast. The fix is two-part.
1. Anchor each kanji in real words. The moment you learn 山 (mountain), meet it inside 富士山 (Mount Fuji) and 火山 (volcano). This is where kanji study and vocabulary study merge — and it is why this guide has a companion. Work through the JLPT N5 vocabulary guide in parallel so every kanji you mnemonic-encode immediately shows up doing real work in sentences.
2. Fight the forgetting curve. In 1885, Hermann Ebbinghaus showed that memory decays predictably — steeply at first, then leveling off. The countermeasure is spaced repetition: review each item just before you are about to forget it, stretching the interval each time you succeed.
Modern algorithms like SM-2 and FSRS automate this. They track how well you recall each card and schedule the next review for the optimal moment, so you spend your time only on the kanji that are slipping.
| Without spaced repetition | With spaced repetition |
|---|---|
| Review everything equally | Review only what's fading |
| Memory decays between sessions | Intervals timed to recall |
| Effort scales with the whole deck | Effort focuses on weak cards |
KaChiKa makes that loop automatic. Photograph a mountain, a tree, or a sign and it becomes the flashcard: the picture is the mnemonic, and the built-in scheduler decides when you see it again. You get dual-coding and spaced repetition without building a single deck by hand.

FAQ
How many kanji do you need for JLPT N5?
By community consensus, the JLPT N5 covers roughly 100 kanji, alongside about 800 vocabulary words. The official JLPT no longer publishes fixed lists, but analysis of past exams puts N5 at around 100 of the most common everyday characters. For context, N4 expands to roughly 1,500 words and N3 to about 3,000 words.
What are radicals and why do they matter for learning kanji?
Radicals are the recurring component parts that make up kanji, such as the 'person' element or the 'tree' element. There are 214 traditional radicals, but a much smaller set covers the vast majority of common characters. Learning radicals first means each new kanji becomes a combination of pieces you already know, which makes mnemonics shorter and recall faster.
Are visual mnemonics better than rote memorization for kanji?
For most learners, yes. Kanji are visual by nature, so they pair well with image-based memory. The Picture Superiority Effect and Paivio's Dual-Coding theory both show that information encoded as both a word and an image is remembered better than words alone. A vivid mnemonic linking a kanji's shape to its meaning is far stickier than copying it dozens of times.
Should I learn kanji or vocabulary first for N5?
Learn them together. Kanji give you the meaning-building blocks, and vocabulary shows those kanji doing real work in words and sentences. A common approach is radicals to kanji to vocabulary: study a kanji's components and mnemonic, then immediately meet it inside a few N5 words so the reading and usage stick.
