Kana Wordle: Learn 400 Japanese Words by Playing One Puzzle a Day

Kana Wordle is a free daily Japanese word game on Ryno Tools: you guess one 4-kana hiragana word in 6 tries, with an English clue shown from the start and learner hints that explain every miss in terms of the kana table. It is built for people still getting comfortable with hiragana who want a reason to touch Japanese every single day. Played alongside a hiragana course, a 3-minute puzzle habit becomes a slow, steady drill through roughly 400 JLPT N5 and N4 words.

TL;DR: Kana Wordle borrows the habit machinery that made Wordle stick (one puzzle a day, streaks, spoiler-free sharing) and points it at Japanese vocabulary. Because the English clue is always visible, each guess is an act of recall rather than blind guessing, and each miss is decoded with ↕, ↔ and ≈ marks that teach consonant rows, vowel columns and voicing marks.

Why does a daily puzzle beat a flashcard session you keep skipping?

Most vocabulary plans fail on consistency, not content. A stack of 800 N5 flashcards is a fine resource that quietly stops being opened in week three. Wordle solved the consistency problem for millions of people, and Jen Clinehens's analysis of its design (UX Magazine, Choice Hacking) points to a few reasons: there is only one puzzle per day, so the game never exhausts you and the wait creates a small craving; a streak makes skipping a day feel like a loss; the colored square grid you share is memorable and spoiler-free, so friends prompt each other to play; and because a new puzzle arrives with each new day, the habit stacks onto morning coffee or a commute. A round takes a few minutes, which is small enough that people actually do it.

Kana Wordle keeps every one of those levers: one 4-kana word at local midnight, a streak and win percentage, a guess distribution, and a spoiler-free emoji grid of green, yellow, orange and gray squares you can paste anywhere.

The second reason a puzzle beats passive review is the testing effect. In Roediger and Karpicke's 2006 experiments, students who repeatedly restudied a passage felt more confident and did slightly better five minutes later, but students who had instead been tested recalled substantially more after two days and after a week. Pulling a fact out of memory strengthens it more than looking at it again. Every Kana Wordle turn is a retrieval attempt: you read the clue, try to produce がっこう from memory, and then have to spell it kana by kana.

The third reason is spacing. Cepeda and colleagues' 2006 meta-analysis of 839 comparisons across 317 experiments found that practice spread over time beats the same practice massed together, and that the ideal gap between sessions grows with how long you want to remember. A once-a-day format is spaced practice by construction, and Practice mode brings words you missed back more often than words you got right, so your weakest items get the most repetitions.

How does Kana Wordle work?

The short version, so the rest of this post makes sense:

• Daily mode gives you one 4-kana hiragana word and 6 guesses. A new word unlocks at midnight in your time zone.
• The English clue is always shown (a description, not the dictionary meaning). Settings has a Hide clue hard mode that withholds the meaning until the game ends and marks your share result as hard.
• Practice mode is unlimited, and Easy mode uses 3-kana words.
• Input is romaji on your keyboard (ka becomes か, kya becomes きゃ, tt becomes っ, nn becomes ん) or taps on an on-screen gojūon keyboard whose ゛゜小 key cycles the last kana through its variants (か → が, は → ば → ぱ, つ → っ).
• Small kana are their own tile. きょう is three tiles; がっこう is four.
• Any well-formed hiragana guess is accepted. There is no ‘not in word list’ rejection, so you can probe with kana you know. If a guess happens to be a real word from the list, its meaning is shown as a bonus.
• After each game you get a word card with kanji, romaji, meaning, part of speech, JLPT level, an example sentence and a pronunciation button that uses your browser's text-to-speech. Every word you meet is saved to a My words panel on your device.

The word list is 546 hand-authored JLPT N5 and N4 words: 415 four-kana words for Daily and Practice, and 131 three-kana words for Easy. Nothing requires an account, and nothing leaves your device.

How do the hints turn every miss into a kana lesson?

This is what makes Kana Wordle a study tool rather than a novelty. Standard Wordle feedback has three states: green (right kana, right spot), yellow (in the word, wrong spot) and gray (not in the word). Kana Wordle adds three learner hints, and each maps to a piece of the gojūon, the traditional 5-by-10 grid that organizes the 46 base hiragana.

In the gojūon, each 行 (gyō, usually translated "row") groups kana that share a consonant, so the か-row is か き く け こ. Each 段 (dan, "column") groups kana that share a vowel, so the a-column is あ か さ た な は ま や ら わ. Voiced marks (dakuten, ゛), semi-voiced marks (handakuten, ゜) and the small kana are derived from that core grid rather than part of it (our hiragana guide walks through all of it). Kana Wordle's hint labels use those standard names, and its on-screen keyboard lays the table out the traditional Japanese way, each consonant row standing as a vertical column with the vowels running across, which is why the consonant hint uses an up-down arrow and the vowel hint a left-right one:

• ↕ means the answer kana in that slot is in the same consonant row as your guess (you played き, the answer has か).
• ↔ means the answer kana in that slot is in the same vowel column (you played ま, the answer has か).
• ≈ means you have the right base kana but the wrong voicing or size (you played た, the answer has だ; you played つ, the answer has っ). It shows as an orange ring around the tile.

Here is a worked example, checked against the game's engine. The answer is がっこう (school). Your first guess is たっこい:

• た ↔ — not in the word, but the answer here (が) is in the same vowel column; た and が are both a-sounds. Slot 1 is an a-column kana other than た.
• っ green and こ green — right kana, right spot.
• い ↕ — the answer here (う) is in the same consonant row. い and う both sit in the あ row, the vowel-only row. Slot 4 is one of あ う え お.

Your second guess is かこいん:

• か ≈ — right base kana, but the answer is the voiced form が. Add the dakuten.
• こ yellow — こ is in the word, just not in slot 2 (your first guess already turned it green in slot 3).
• い and ん gray — not in the word at all.

Two guesses in, you have not just narrowed the answer; you have rehearsed the three things beginners most often get wrong. The ↔ mark made you think about which kana share a vowel with た. The ↕ mark made you scan the あ row. The ≈ mark reminded you that か and が are the same shape with a different sound, and that the difference changes the word. Over dozens of puzzles those scans become automatic, which is exactly the fluency you need to stop reading hiragana one character at a time. A dot on a keyboard key reinforces the same idea: it means one of that key's variants (が, っ and so on) already has a known state, so you learn to treat か and が as a family.

Exam tip: The JLPT N5 expects you to read typical sentences written in hiragana, katakana and basic kanji, and its vocabulary questions test exact spellings. Voicing and small kana are where beginners lose points: がっこう (school) is not かっこう, and きって (stamp) is not きて. The ≈ hint drills exactly that distinction every time it appears, so pay attention to it rather than clicking past it.

If the arrows feel like too much help, switch learner hints off in Settings and play with plain green, yellow and gray. The mechanics owe a clear debt to Kotobade Asobou (言葉で遊ぼう), the earlier Japanese-language Wordle, which also uses 4-kana words and marks close kana, matching vowels and matching consonants with similar symbols. Kotobade Asobou gives 12 tries, requires a valid dictionary word, and assumes you already read Japanese. Kana Wordle is the beginner's version: 6 tries, an English clue from the start, and hints explained in terms a first-month learner can use.

What does Kana Wordle not do?

An honest scope note, because a game that overpromises is worse than one that does not:

• It does not teach grammar. Each word card's example sentence shows the word in context, but there is no explanation of particles or conjugation. The Sentences track at ryno.tools/japanese/ does that.
• It does not drill kanji reading. Kanji appear on the word card so you recognize the written form, but you type and see hiragana only.
• It does not cover katakana. Every answer is native hiragana vocabulary; loanwords are out of scope. See hiragana vs katakana for why katakana is a separate job.
• It is not the full N5 list. 546 words against the ~800 usually cited for N5, with N4 words mixed in, so treat it as a core-vocabulary drill, not a checklist. Our JLPT N5 overview explains what the test actually asks.
• Stats live on one device. There is no account, so a streak on your phone does not carry to your laptop.

Kana Wordle is a supplement, not a course. Pair it with real lessons and it earns its place; use it alone and you will learn 400 words and not much else.

How do you pair the game with hiragana lessons? A four-week plan

This plan assumes 15 minutes a day: about 10 on the hub's lessons and 3 to 5 on the puzzle.

Week 1 — the base 46. Work through the vowel row and the か through な rows in the hiragana lessons at ryno.tools/japanese/. In the game, stay in Easy mode (3-kana words) with hints on, and use the on-screen kana keyboard rather than romaji so you are looking at hiragana shapes, not Latin letters. Expect lots of gray; that is fine.

Week 2 — finish the grid, add dakuten. Cover は through ん, then the voiced and semi-voiced rows (が ざ だ ば ぱ). Move to the Daily puzzle and start typing romaji so your fingers learn that ga and ka are one modifier apart. When you see ≈, say the pair out loud (か, が) before fixing it.

Week 3 — small kana and yōon. Learn っ and the きゃ きゅ きょ combinations. Open My words, tap Practice missed words, and clear the backlog from weeks one and two. Start sharing your emoji grid with a study partner; a second person is the cheapest streak insurance there is.

Week 4 — remove the scaffolding. Turn on Hide clue in Settings to test true recall on the Daily puzzle, and switch it back off whenever a Practice word is new to you. Read each example sentence in My words aloud with the pronunciation button. By now you read hiragana at a glance, you have met well over a hundred N5 words, and you are ready for the Vocabulary and Sentences tracks on the hub. Keep the daily puzzle going; it costs three minutes and protects everything you just built.

Frequently asked questions

Is there a Japanese Wordle?

Yes. Kana Wordle on Ryno Tools is a free daily Japanese Wordle for learners: one 4-kana hiragana word, 6 guesses, an English clue from the start, and hints that explain each miss using the kana table. Kotobade Asobou is an earlier Japanese-language Wordle for people who already read Japanese, with 4-kana words, 12 tries and a dictionary-word requirement.

Do I need to know the word already?

No. The clue gives you the meaning and the tiles teach you the spelling. Any well-formed hiragana guess is accepted, so start with kana you know and let the green, yellow, gray, ≈, ↕ and ↔ feedback narrow the answer. When a guess happens to be a real word from the list, its meaning is shown as a bonus.

Does Kana Wordle work offline?

Yes. Ryno Tools is a progressive web app. After you have opened Kana Wordle once while online, the page, word list and styles are cached on your device and the game keeps working without a connection. Your streak, statistics and My words list are stored locally on that device only.

Do small kana count as their own tile?

Yes. Each hiragana character is one tile, so きょう is three tiles and がっこう is four. The ゛゜小 key cycles the last kana through its voiced, semi-voiced and small variants, and in romaji a doubled consonant (tt) produces っ.

How many words are in Kana Wordle?

546 hand-authored JLPT N5 and N4 words: 415 four-kana words for Daily and Practice, and 131 three-kana words for Easy mode. Each word card shows kanji, romaji, meaning, part of speech, JLPT level, an example sentence and a pronunciation button.
