Bunpro Review: Best Grammar Tool, But Is It Enough? (2026)

Overview

If WaniKani is the king of kanji SRS, Bunpro is the king of grammar SRS. It takes the spaced repetition system that works so well for kanji and applies it to Japanese grammar -- every particle, every conjugation, every sentence pattern from JLPT N5 all the way through N1.

For $5 a month, it's one of the best deals in Japanese learning. But there's a question the Bunpro community asks constantly -- so often it's practically a meme on their forum: 'How do I practice speaking?'

That question tells you everything about what Bunpro does (brilliantly) and what it doesn't do (at all). This review covers both sides.

‍

What is Bunpro?

Bunpro is a web app that teaches Japanese grammar through spaced repetition and cloze deletion exercises. You're given a sentence with a blank where the grammar point goes, and you type the correct answer. Get it right, the review interval extends. Get it wrong, it comes back sooner.

The platform covers 900+ grammar points from JLPT N5 through N1, with clear explanations, example sentences, and links to external grammar resources. It integrates with popular textbooks (Genki, Tobira, Minna no Nihongo) so you can study grammar in the same order as your textbook.

Pricing: $5/month, $50/year, or $150 lifetime. There's a 30-day free trial.

What Bunpro Does Brilliantly

‍

Grammar Coverage from N5 to N1

This is Bunpro's superpower. While most grammar resources cover basics (N5-N4), Bunpro goes all the way to N1 -- the advanced level that most textbooks don't even attempt. If you're preparing for any JLPT level, Bunpro has the grammar points you need, organised by test level and difficulty. That comprehensiveness is rare and genuinely valuable.

‍

SRS That Makes Grammar Stick

The cloze deletion format forces active recall -- you can't just recognise the answer, you have to produce it. That active engagement makes grammar patterns stick in a way that reading textbook explanations doesn't. Over weeks and months, patterns that felt foreign become automatic. The SRS timing ensures you review grammar points right before you'd forget them.

‍

Textbook Integration

Following Genki? You can set Bunpro to present grammar in Genki's chapter order. Using Tobira? Same thing. This integration means Bunpro reinforces whatever textbook or course you're using rather than competing with it. It's designed to be part of your stack, not your entire stack -- and that self-awareness is refreshing.

Bunpro is genuinely one of the best grammar tools available. Here's what it can't do...

‍

What Bunpro Does NOT Teach

‍

Speaking: The Community's #1 Request

Search the Bunpro forum for 'speaking practice' and you'll find dozens of threads. 'Getting better at speaking? Practice suggestions?' 'How do you practice speaking?' 'Cheap/effective speaking practice for Japan trip.' The community knows this is the gap, and they're actively looking for solutions.

Bunpro teaches you grammar rules through typing exercises. It does not ask you to speak those rules out loud, use them in conversation, or apply them in real-time interaction. You learn about Japanese grammar. You don't learn to use it.

‍

Listening Comprehension: Absent

Bunpro includes audio for example sentences, but there's no listening practice for natural-speed conversation. Real Japanese comes at you fast, with dropped particles and casual contractions. Bunpro's clean written sentences don't prepare you for that.

‍

SRS Burnout: A Real Problem

This is less about what Bunpro doesn't teach and more about how it teaches. With 900+ grammar points, review queues can pile up rapidly. Multiple forum threads describe being overwhelmed with hundreds of daily reviews, leading to burnout. The system is effective but demands consistent daily engagement -- skip a few days and the review mountain grows.

‍

The WaniKani + Bunpro Gap

Many Japanese learners run both WaniKani and Bunpro simultaneously. Combined annual cost: approximately $139. Combined coverage:

‍

Kanji: covered. Grammar: covered. Speaking and listening: completely uncovered. You can spend $139/year on two excellent tools and still be unable to hold a basic Japanese conversation.

That's not a failure of either tool -- it's a stack that's missing its most important layer.

Completing the Stack

‍

The most effective Japanese learning stack combines:

• WaniKani for kanji recognition ($9/month)
• Bunpro for grammar drilling ($5/month)
• A live course for speaking, listening, and applying what WaniKani and Bunpro teach

‍

Japademy's 10-week courses are purpose-built for this: weekly live classes where you use grammar patterns in real conversation with a certified native teacher and classmates at your level. $279 USD for 10 weeks -- all materials included.

‍

Keep your WaniKani reviews. Keep your Bunpro drills. Add the speaking layer that makes both of them actually useful in the real world.

Who Should Choose What

Keep using Bunpro if you...

• Want systematic grammar drilling from N5 to N1
• Enjoy SRS-based learning and can maintain daily reviews
• Are following a textbook and want reinforcement exercises
• Are willing to find separate resources for speaking and listening

‍

Add a live course if you...

• Know grammar rules but can't apply them in conversation
• Want a certified teacher to explain nuances that cloze exercises can't capture
• Need speaking practice -- the skill Bunpro's own community asks about most
• Are experiencing SRS burnout and want a different kind of engagement

What Students Say

'Bunpro taught me every grammar pattern from N5 to N3. I could ace written quizzes. But the first time I tried to use those patterns in a real conversation, my mind went blank. Knowing grammar and using grammar are completely different skills. Adding a weekly live class where I had to actually produce those patterns out loud was transformative.' - Nurys A.

'I was drowning in Bunpro reviews -- 200+ per day, getting burned out. Joining a live class gave me a different kind of engagement. Speaking with classmates, hearing the teacher use grammar naturally, laughing when we all make the same mistake. It recharged my motivation in a way that no SRS app ever could.' - Trenton B.

Frequently Asked Questions

‍

Is Bunpro worth it for Japanese grammar?

For grammar specifically, yes. At $5/month or $150 lifetime, Bunpro covers N5 through N1 with 900+ grammar points. But it only covers grammar -- no speaking, listening, or live interaction.

‍

Does Bunpro teach you to speak Japanese?

No. Bunpro is text-based grammar drilling with no speaking exercises, conversation features, or pronunciation practice.

‍

What should I pair Bunpro with for speaking?

A live course like Japademy ($279/10 weeks) provides weekly speaking practice where you use the grammar patterns Bunpro teaches in real conversation.

‍

Is WaniKani plus Bunpro enough?

Together they cover kanji and grammar but leave speaking and listening uncovered. Combined cost ~$139/year -- and you still can't hold a conversation without additional resources.

‍

Can Bunpro replace a Japanese course?

No. Bunpro replaces grammar exercises, not an entire course. A course includes grammar, speaking, listening, teacher feedback, and structured progression. Bunpro covers one of those five elements.

Bunpro is one of the best tools in the Japanese learning ecosystem. Use it. It's excellent at what it does. Just remember that grammar knowledge without speaking practice is like learning to drive by reading the manual -- technically correct, but you'll stall the moment you turn the key.
