About iroiro JLPT: Japanese Vocab
Japanese? The real problem is kanji.
You've tried flashcard apps. You've ground through vocabulary lists. But kanji just won't stick — because you've been memorizing shapes instead of understanding structure.
Every kanji is built from smaller components called radicals. Learn the radicals, and kanji stops being a wall of random strokes. It becomes a system — one you can actually read, remember, and use.
iroiro JLPT is a Japanese vocabulary app designed to make kanji click, not just cram.
How it works
We break each kanji into its radicals, then lock the meaning in place with a vivid mnemonic — a short, memorable image that connects the pieces to the whole. Instead of seeing 休 as an arbitrary symbol, you see a person (亻) leaning against a tree (木) to rest. That's not a trick. That's how the character was built.
Do this consistently, and something shifts: unfamiliar kanji starts to look readable. You recognize the parts, guess the meaning, and you're right more often than you'd expect.
What makes iroiro JLPT different
◦ Radical decomposition + mnemonics for every kanji — understand the structure, not just the stroke order
◦ Vocabulary and kanji learned together — double the efficiency in the same study time
◦ FSRS spaced repetition algorithm — review exactly when you need to, skip what you already know
◦ Hiragana & katakana through visual association — master the basics fast
◦ Example sentences + native audio — hear how words actually sound in context
◦ Kanji writing practice — go from recognition to production
◦ Step-by-step JLPT levels (N5 → N1) — a clear path from beginner to advanced
◦ Content reviewed by a former Japanese textbook author
◦ Cross-device sync — pick up where you left off on any device
Built for you if…
You want to learn Japanese but kanji feels like a wall.
You've been stuck on conversation because reading feels impossible.
You started with a gamified app but hit a ceiling once kanji showed up.
You've tried flashcard apps but the setup was too much work.
You can chat in Japanese but can't read a menu.
You've used other JLPT apps but kanji learning always felt like an afterthought.
You review and review but forget everything within a week.
You're tired of planning what to study instead of actually studying.
Your learning flow
1. Master hiragana & katakana with visual mnemonics
2. Choose your JLPT level (N5 – N1)
3. Break down each kanji into radicals
4. Lock it in with a mnemonic
5. Review at the optimal time — powered by FSRS
6. Confirm with example sentences and audio
7. Seal it with writing practice
Stop fighting kanji. Start understanding it.

Review momentum
65/100
faster than 73% of Education apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About iroiro: Japanese Vocab & JLPT
Japanese? The real problem is kanji.
You've tried flashcard apps. You've ground through vocaabulary lists. But kanji just won't stick — because you've been memorizing shapes instead of understanding structure.
Every kanji is built from smaller components called radicals. Learn the radicals, and kanji stops being a wall of random strokes. It becomes a system — one you can actually read, remember, and use.
iroiro is a Japanese vocabulary app designed to make kanji click, not just cram.
How it works
We break each kanji into its radicals, then lock the meaning in place with a vivid mnemonic — a short, memorable image that connects the pieces to the whole. Instead of seeing 休 as an arbitrary symbol, you see a person (亻) leaning against a tree (木) to rest. That's not a trick. That's how the character was built.
Do this consistently, and something shifts: unfamiliar kanji starts to look readable. You recognize the parts, guess the meaning, and you're right more often than you'd expect.
What makes iroiro JLPT different
◦ Radical decomposition + mnemonics for every kanji — understand the structure, not just the stroke order
◦ Vocabulary and kanji learned together — double the efficiency in the same study time
◦ FSRS spaced repetition algorithm — review exactly when you need to, skip what you already know
◦ Hiragana & katakana through visual association — master the basics fast
◦ Example sentences + native audio — hear how words actually sound in context
◦ Kanji writing practice — go from recognition to production
◦ Step-by-step JLPT levels (N5 → N1) — a clear path from beginner to advanced
◦ Content reviewed by a former Japanese textbook author
◦ Cross-device sync — pick up where you left off on any device
