About Kanjijo

Mastering Kanji, Simplified.

Our Story

As Japanese learners ourselves, we know the struggle all too well. Kanji feels like an endless mountain — thousands of characters, each with multiple readings, countless vocabulary combinations, and no clear roadmap on where to start.

We spent years battling the same frustrations: forgetting kanji we’d studied just days ago, feeling lost without a structured system, and jumping between scattered resources that never quite connected the dots.

That’s exactly why we built Kanjijo.

Our Philosophy

Minimalist. Focused. Intentional.

We believe that a cluttered app leads to a cluttered mind. Our interface is designed to keep you focused on what matters: the Kanji. Currently supporting English and Vietnamese, with more languages on the horizon.

Learning Path

To ensure true mastery, Kanjijo uses Sequential Unlocking. You must pass the proficiency test of your current lesson to unlock the next. This ensures quality learning — no skipping ahead, no gaps in knowledge.

Pricing Plans

Free Tier

Free users get full access to our learning content — one new lesson per day. Each lesson covers approximately 20 vocabularies, the ideal amount for daily study. You also get access to smart review reminders, the home screen widget, and all core features. To unlock a new lesson, you can choose to watch a short rewarded ad — but only when you decide to. We never interrupt your learning with unwanted advertisements.

Premium Tier

Need more? Premium users can unlock unlimited lessons per day with absolutely no ads — not even rewarded ad prompts. The sequential unlock system still applies to maintain learning quality, but there’s no daily limit holding you back. And you get access to full features of the app.

We hope Kanjijo becomes your trusted companion on the path to mastering Japanese. This is just the beginning — we’re constantly improving and adding new features.
