Frequently Asked Questions

Picture turning kanji study into an epic adventure, where each symbol is a card to collect and every Quiz a challenge to conquer. Kanjidon is an app that mixes gamification with learning, using a spaced repetition system (SRS) to lock kanji into your long-term memory.

Open packs, tackle dynamic Quizzes, follow lessons, and track your progress with detailed stats. Whether you’re a beginner or a Japanese pro, Kanjidon makes every step fun and rewarding.

Kanjidon turns kanji into collectible cards with unique designs, like a trading card game. Each kanji has a rarity, and collecting them levels you up, all the way to 50!

Missions, rewards, and a global leaderboard add a competitive edge, while the SRS ensures you’re learning for real, stress-free. It’s studying that feels like a game!

There are thousands of collectible cards (we’re already over 3,000) on Kanjidon, updated monthly. Basically, you’ve got all the tools to live, work, or travel in Japan, and even read manga or ace the world’s most famous Japanese exam: the JLPT.

No way! Kanjidon is your all-in-one buddy for learning Japanese. Besides kanji cards, you’ll find hiragana and katakana cards (for total beginners), plus vocab and grammar cards to master Japanese from every angle.

You get cards from packs, and they’re all waiting to be discovered. There are different types of packs, with N5 as the starter level. Each pack can have 4 or 6 Kanjidon cards, which get added to your Collection. Get opening!

The Home is your command center: here you’ll find the Pack Opening section to open new packs, the heart of the app. But that’s not all—you’ll also get Lessons to dive into Japanese grammar! Plus, there’s your profile with a custom avatar, a counter for your Daily Goal (tap it for details), a Tama coin counter, and the News Center for the latest updates.

It’s designed to be super intuitive: one tap, and you’re ready to study or collect.

In the News Center, top right on the Home screen. It’s your personal bulletin for seasonal events, new cards, features, and official updates.

Stay in the loop so you don’t miss surprises or exclusive bonuses! Notifications stick around, so even if you’re new, you can check out past news—it’s always nice!

With the menu bar at the bottom of the screen, switching between Home, Collection, Quiz, Stats, and Profile is a breeze. One tap, and you’re where you want to be, no hassle.

Smooth navigation for a seamless experience.

The cards are the core of Kanjidon: JLPT-themed packs (Kana, N5, N4, N3, N2, and even N1) each have 4 Kanjidon cards (6 for Premium users!). You need 30 Tama, the Kanjidon world’s coins, to open a pack. Open as many cards as you can and check out what they offer: each card has a meaning, an on reading, a kun reading, and an example sentence… everything you need to learn kanji the best way!

The JLPT (Japanese Language Proficiency Test) is a test to check your Japanese skills. It’s split into five levels, from N5 (beginner) to N1 (advanced), and it’s used to certify your Japanese language abilities.

Kanjidon organizes cards by these levels, so you can study in a focused, structured way. If you’re starting from scratch, begin with the Kana packs: they only have hiragana and katakana, the two Japanese syllabic alphabets!

Cards range from 1 to 4 stars, with unique designs for each rarity. There are also super-rare golden cards and special two-star golden event variants, available only during specific periods.

With over 20 thematic types (Nature, Fire, Sky, etc.), each card is a work of art that keeps your Collection fresh and exciting.

Free users can open up to 3 packs a day. It's a perfect pace to stay consistent without feeling overwhelmed.

Open, discover, repeat: every day's a new adventure.

Once you’ve opened packs, your cards go to the Collection, the perfect spot for studying and reviewing. Here, you can see all your cards and use the bottom-right button to filter by rarity, JLPT level, type, or opening date.

It’s your personal album, and you should use it for your study sessions.

In the Collection, just above the filter button, there’s a button for the Full Collection, sorted by Kana and JLPT levels (N5, N4, N3, N2, N1). Here, you can see how many cards you’re missing to complete the entire Kanjidon Collection and become a true Japanese Sensei.

You bet! Each kanji card has tons of extra info to boost your studies. In the Collection, tap a card. You’ll see an INFO button at the bottom of the screen. Tap it, and you’ll unlock a whole world about that kanji! Pronunciation, similar kanji, stroke order… everything you need. Try it now!

As you do Quizzes, kanji change status. They go from ‘new’ to ‘memorized’ if you answer correctly in Quizzes! If you get one wrong, it becomes ‘to review,’ and the algorithm will show it more often until you nail it.

The symbols on kanji are: N (new, just collected), M (memorized, if you got it right in Quizzes), R (to review, if you got it wrong once), and E (error, if you got it wrong twice in a row). Do lots of Quizzes and aim for all kanji to be M!

The little x2 or x3 symbol on cards in your Collection shows how many copies you have of that card. Yup, packs can give you duplicates, just like in real life! Good news: duplicates aren't useless—you can trade them for an Omikuji, a Japanese fortune oracle.

Absolutely! When viewing a card in the Collection, you'll see the Notes button at the top of the screen, right above the card. Press it to add your personal notes about that kanji: mnemonic tricks, example sentences, or anything that helps you remember it better.

Your notes sync automatically across all your devices, so you can keep studying anywhere with your annotations always at hand!

Yup, just like in real life! Every pack opening is an adventure, and it can go great, good, or not so great, meaning you might get cards you already have in your Collection! But don’t worry, you can still make use of them.

In the Pack Opening section, scroll down, and you’ll see a button to access Omikuji draws, the famous Japanese fortune oracles. If you have 5 copies of the same card, you can trade 4 for an Omikuji.

Omikuji are in the Pack Opening section for a reason—they’re a real adventure. You can draw lucky or unlucky oracles, but the best Omikuji give bonuses like extra coins or Quiz Keys!

Turn duplicates into opportunities: every card counts!

Yeah, besides Omikuji, you can also trade your duplicates to get a Kanjidon card you don't have. Go to Collection, and press the button to view the full Collection. You'll see the cards you don't own are semi-transparent. Try tapping one! It'll start the trade process.

Decks are collections of cards you can create and customize however you want. You can group cards by themes, difficulty levels, or any criteria you like. It's a way to organize your Collection and study efficiently!

In the Collection section, tap the Decks button, then tap to create a new Deck. You can name your Deck, pick an icon and color, and start adding cards. Experiment with different combos and themes!

For sure! Once you've created a Deck, you can always edit it by tapping the pencil button. Add or remove cards, change the name or icon, customize it however you want, or delete it. Decks are flexible and adapt to your study needs.

If you long-press a Deck you created, you can also move it to the top of the list, so you can find it more easily.

You can use the Decks to do targeted quizzes. In the Quiz section, hit the Filter button and pick the Deck you wanna use. That way, you can focus on specific study spots and boost your skills way better!

In the menu bar, the third button is for Quizzes. This is the spot to train hard and test yourself to see if you’ve studied your kanji well in the Collection section.

You bet! There’s not just one type of Quiz—there are tons, and new ones keep coming! That’s because it’s better to tackle Japanese from every angle, never get bored, and learn kanji and grammar from every possible perspective.

Each Quiz section has 10 questions, but every time you get one wrong, that kanji goes back in the queue and pops up again during the Quiz section. Kanjidon's powerful SRS algorithm tailors your Quiz sections based on your Collection, mistakes, and successes, making every session super effective.

A Quiz isn't a test—it's a challenge to grow and improve your skills.

Kanjidon uses the SM-2 algorithm, a scientifically validated spaced repetition system used by millions of students worldwide. It's based on decades of neuroscience research on how your brain forms memories.

Each kanji has its own score that adapts to your learning: if you answer correctly, it will be shown again after increasingly longer intervals. If you make a mistake, the interval shortens to help consolidate your memory.

This approach lets you review right before you forget, maximizing retention with the fewest repetitions possible.

Yup! From the Quiz section, use the Filter button at the bottom right. You can pick your JLPT level (N5, N4, N3, N2, or N1) or even filter by Kana to practice just hiragana and katakana. It’s a system that adapts to your pace, skipping stuff that’s too easy or too hard.

Learn what you need, when you need it!

No worries! Above the Filter button, there’s a Random Quiz button, a super handy feature that picks a Quiz for you randomly. Perfect for those moments when you can’t decide which Quiz to do! After all, every Quiz is special and useful, and mixing them up gets you the most benefit.

Every correct answer earns you 1 Tama, the currency of Kanjidon’s world. The cool part? If you ace a session—10 correct out of 10—you get a +5 Tama bonus! Plus, correct answers move your cards to ‘memorized’ (M) status, and you earn Tama to open new packs and grammar lessons.

Ps: every correct answer gives you Experience Points (XP) to climb the Ranking, but every wrong answer… makes you lose XP!

The ‘Decidi’ Quiz is unlimited for everyone. Other Quizzes are for Premium users only, but don’t stress! Every day, you can get a Quiz Key, a special key that unlocks one Premium Quiz! That way, you can try them out and find the style that suits you best.

Give them all a shot!

If you're a free user, you get one free Quiz Key a day! Each Premium Quiz costs one key, but if you nail 5 perfect Quiz sections (10/10), you score an extra key.

Keys are your pass to new challenges!

Yup, every 5 perfect sections (10/10) gets you an extra Quiz Key. It’s a reward for your consistency and precision.

Aim for perfection and unlock more opportunities!

You can have up to 5 Quiz Keys at once. If you already have 5, you won't be able to get more until you use some.

On Kanjidon, you can customize your Avatar in the Profile section, the last button in the menu bar. Have fun switching up your Avatar to make your Kanjidon experience your own.

Did you know you can level up on Kanjidon? You start at level 1, and you can keep climbing. It all depends on how much you open packs!

Besides your 1-50 level, Kanjidon also tracks your actual JLPT level based on the kanji you've memorized! When you hit 50% memorized kanji for a JLPT level, your profile shows a colored badge and the level box changes color.

The progression goes: N5 (green) → N4 (light blue) → N3 (amber) → N2 (purple) → N1 (red). You gotta complete each level before moving to the next. It's your real progress in Japanese!

Besides the Avatars you unlock with levels, there are also super special Avatars you can unlock every month with the World Ranking. If you make it to the top 10 positions or even 1st place, on the first day of the next month you'll get a notification saying you’ve scored an awesome Avatar.

Basically, you can win a new Avatar every month if you rock the Ranking!

In the Home, under the Unpack button, you'll find the Practice section. Here you can decide to learn a bunch of Kanji properly each day, learn grammar with dozens of lessons, and read and translate super fun stories!

With the Kanji section, you can randomly pick a number of Kanji from your Collection (5, 10 or however many you want) and learn them properly. You'll get sentences to read and repeat, so you absorb all the Kanji in your Collection at a gradual pace!

It's your daily dose of Japanese learned well!

In the Practice section, you'll find the Grammar button. This is the right spot for you when you've had your fill of Kanji and want to learn Japanese grammar. These are the two big pillars that'll get you to conquer Japanese, so don't underestimate grammar or Kanji. They gotta go hand in hand!

Lessons are structured paths to learn Japanese, from basics to advanced grammar, including greetings, adjectives, conjugations, and everything you need to build your sentences right. Each lesson costs 30 Tama and includes Quizzes to lock in what you learn.

Every step is a chapter that gets you closer to mastering Japanese!

The first step is accessible to give you a taste and kick off your adventure right away.

What actions? It's a mystery, you'll have to find out yourself. Collecting all Stamps is an extra challenge that adds flavor to your journey.

Explore and uncover Kanjidon's hidden secrets!

Kanjidon has 5 Leagues based on JLPT levels: N5 (green), N4 (blue), N3 (terracotta), N2 (purple), and N1 (red). Each League has its own separate monthly Leaderboard, so you can compete with players at your same level!

Pick your League in the Leaderboard section and start climbing the ranks!

The first time you open the Leaderboard, you'll be asked to pick a League among N5, N4, N3, N2, and N1. Choose based on your current Japanese level! You can always switch Leagues later from the same section.

Starting with N5 is perfect for beginners, while N1 is for real experts!

Each League has its own independent monthly Leaderboard. Do Quizzes to earn Experience Points (XP): every correct answer is worth points that vary by League (harder = more XP!). Perfect sessions (10/10) give you bonus XP.

Each League has different difficulty levels: N1 offers up to 500 XP for a Battle win, while N5 offers 100 XP. Climb your League and become champion!

Each League's monthly tournament closes 3 days before the end of the month and restarts on the 1st. XP resets every month, giving everyone a fresh chance to win!

The top 10 players in EVERY League win exclusive monthly avatars. 1st place gets an even more special avatar!

Battle is where you challenge other players to real-time Quiz duels! You can challenge a friend locally, a random player online, or face a CPU opponent.

Every Battle is a test of speed, precision, and strategy with Power-ups!

In the Battle section, press 'Local Battle'. Generate a code and share it with a friend who's near you. They enter the code, join the room, and the one-on-one challenge starts!

Perfect for playing together and seeing who's the best!

Press 'Online Battle': the system automatically pairs you with a player from your same League and similar Rank. Matchmaking guarantees balanced challenges!

If it can't find anyone in 6 seconds, you'll face a CPU opponent. Win to climb Ranks and earn extra XP!

Battle has 3 steps, for a total of 15 questions (5 per step). You'll get on readings, kun readings, and meanings. Answer correctly and quickly to earn XP!

Every correct answer earns you points, but watch out: wrong answers make you lose XP. The key is balancing speed and accuracy!

During Battle, answering correctly earns you Power-ups to use to your advantage! Each battle has 3 power-ups randomly selected from these 7:

Use them strategically to win!

After 15 questions, whoever answered the most questions correctly wins. In case of a tie, whoever has the lowest average response time wins.

Each step has a countdown: when it runs out, it automatically moves to the next step. Speed and accuracy are essential!

Rank is the tier that measures your Battle skill. You start at Rank E (beginners) and climb up to S (experts), passing through D, C, B, and A.

Your Rank is visible on the badge on your Avatar and determines who you'll be matched with in Online Battles!

Win Battles to climb Ranks! The Ranks are:

• E (beginners)
• D
• C
• B
• A
• S (experts)

Watch out: losing battles can make you drop Ranks!

Each Rank has a different mix of kanji based on your League:

N5 League: Rank E starts with 100% Kana, then progressively introduces N5 kanji until Rank S (100% N5).

Other Leagues: Rank E has 70% kanji from the previous level and 30% from the current level. As you climb Ranks, the mix reverses until reaching 100% of the current level at Rank S.

The higher your Rank, the harder the kanji you face!

Every correct answer earns you XP (varies by League), and winning a Battle gives you a huge bonus:

• N5: +100 XP win
• N4: +150 XP win
• N3: +200 XP win
• N2: +300 XP win
• N1: +500 XP win

Harder Leagues offer bigger rewards!

Yup! Every 5 battles you win, you get 1 Mon, a special currency you'll need to open Special Packs. Every month you'll find a new themed Special Pack, and you need 1 Mon to open each one

Kanjidon rewards you for building a winning streak! Every time you win, your streak grows and you earn bonus XP:

• 2 wins: +10 XP
• 3 wins: +20 XP
• 5 wins: +40 XP
• 10 wins: +90 XP
• 11+ wins: +100 XP (max)

But watch out: if you lose or draw, your streak resets and you'll have to start over. Local battles with friends don't count.

Your streak also resets at the start of each month, along with the Leaderboard. Go for those consecutive wins to maximize your XP!

Special Packs are exclusive monthly themed packs! Every month you'll find a new Special Pack with unique legendary cards dedicated to a specific theme. They're only available during their month, so if you miss one... it's gone forever!

Every Special Pack is a themed adventure that lets you discover Japanese cultural curiosities through legendary cards.

To open a Special Pack you need 1 Mon, a special currency you get every 5 Battles won, against a friend or a random opponent. Once you've collected at least 1 Mon, go to the Pack Opening section, tap the star icon and open your Special Pack using 1 Mon.

Inside every Special Pack you'll find super rare legendary cards (✴️✴️) dedicated to the month's theme. These are cards you can't find in regular packs, with exclusive designs and detailed descriptions that tell you about Japanese cultural curiosities.
