JLPTLord vs Bunpro: Vocabulary vs Grammar Focus

Why This Comparison Matters

The JLPT tests two core language skills that require dedicated study: vocabulary and grammar. Most learners eventually realize they need separate tools for each, because no single app does both equally well. Bunpro and JLPTLord are frequently mentioned together in JLPT study communities precisely because they each excel at one of these two skills. Understanding how they differ — and how they overlap — helps you build a study plan that covers all your bases without wasting time or money on redundant tools.

This is not a typical "which one is better" comparison because these tools are not really competing. Bunpro does not try to be a comprehensive vocabulary app, and JLPTLord does not try to be a grammar teaching platform. They occupy different lanes. The real question is whether you need one or both, and how to use them together effectively if you choose both. We will examine each tool in depth, compare their features side by side, and give you honest recommendations based on your goals and budget.

Whether you are just starting with JLPT N5 or grinding toward N1, the combination of strong vocabulary and solid grammar knowledge is what separates candidates who pass from those who fall short. Let us look at how each tool helps you get there.

Learning Approach: Vocabulary vs Grammar

JLPTLord: Vocabulary-First, Exam-Aligned

JLPTLord is built around one core mission: ensure you know every vocabulary word that could appear on your target JLPT level. The platform organizes its 10,000+ words by JLPT level, from the approximately 800 words at N5 through the 10,000+ words needed for N1. Every word is presented with kanji, furigana (hiragana reading), romaji, and English meaning — giving you every representation you will encounter on the exam or in real life.

For example, the word 経験 (けいけん / keiken) — experience — appears with its kanji form, the hiragana reading in parentheses, the romanized pronunciation, and the English definition. This multi-format display means you can recognize the word whether you see it written in kanji in a reading passage, hear it spoken in the listening section, or encounter it in a vocabulary question. JLPTLord uses spaced repetition to schedule reviews at optimal intervals, and tracks your mastery percentage for each JLPT level so you always know how close you are to full coverage.

JLPTLord also includes a placement test that identifies words you already know, so intermediate and advanced learners do not waste weeks reviewing basic vocabulary. You start at your actual level and focus your time on the words you have not yet mastered. This efficiency is critical for learners with a specific exam date approaching.

Bunpro: Grammar-First, SRS-Driven

Bunpro takes the concept of spaced repetition — typically applied to vocabulary flashcards — and adapts it for grammar. Instead of showing you a word and asking for its meaning, Bunpro presents an example sentence with a blank where a grammar point should go. You must type or select the correct grammar construction in context. This active recall approach forces you to understand not just what a grammar point means, but when and how to use it.

Bunpro covers approximately 800 grammar points across all JLPT levels. Each point includes a clear explanation, nuance notes comparing it to similar grammar, multiple example sentences from different sources, and links to textbook references (Genki, Tobira, A Dictionary of Japanese Grammar, and others). The SRS algorithm tracks your accuracy for each grammar point and adjusts the review schedule accordingly — grammar patterns you struggle with appear more frequently, while those you have mastered fade into longer intervals.

For JLPT preparation, Bunpro's organization by level is extremely convenient. You can select "N3 Grammar" and study only the grammar points tested at that level, working through them systematically. The fill-in-the-blank format also mirrors how grammar is tested on the JLPT, where you must choose the correct grammatical construction to complete a sentence.

Feature-by-Feature Comparison

The following table compares JLPTLord and Bunpro across every major dimension. Since these tools target different skills, many features are complementary rather than directly competing.

JLPT Alignment: Both Get This Right

One of the strongest shared qualities of JLPTLord and Bunpro is that both tools organize their content by JLPT level. This is not the case with many other Japanese learning tools — some follow their own curriculum order, some organize by textbook chapter, and some have no JLPT alignment at all. When you are preparing for a specific exam date, being able to filter content by your target level is essential.

On JLPTLord, you select your target level and study the complete vocabulary list for that level. The platform shows you exactly how many words are in each level and what percentage you have mastered. On Bunpro, you select your target level and study the grammar points assigned to that level, with clear progress tracking showing which points you have learned and which remain. This parallel organization makes it natural to use both tools for the same level simultaneously — studying N3 vocabulary on JLPTLord and N3 grammar on Bunpro, for example.

The JLPT tests vocabulary and grammar in the same section of the exam (Language Knowledge / 言語知識), so having strong preparation in both areas is not just helpful — it is required. A candidate who knows every vocabulary word but cannot parse grammar structures will struggle with reading passages. A candidate who understands every grammar point but lacks vocabulary will not be able to understand what the sentences are about. This is precisely why the JLPTLord and Bunpro combination works so well.

How Their SRS Implementations Differ

Both JLPTLord and Bunpro use spaced repetition, but they apply it to fundamentally different types of content, which means the review experience feels quite different. Understanding these differences helps you know what to expect from each tool.

JLPTLord's SRS is optimized for vocabulary retention. Each review shows you a word and asks you to recall its meaning (or shows the meaning and asks you to recall the word). The system tracks your accuracy and adjusts the interval — words you know well might not appear again for weeks, while words you miss will reappear within a day or two. Because vocabulary items are relatively discrete (each word is a self-contained unit), the SRS is straightforward and fast. Most learners can review 50-100 words in a 15-minute session, making it easy to maintain a daily habit. Learn more about the science behind this on our spaced repetition science page.

Bunpro's SRS is adapted for grammar, which presents unique challenges. Grammar points are not discrete items you can simply memorize — they require understanding context, nuance, and when to use one construction versus a similar alternative. Bunpro addresses this by presenting grammar as contextual fill-in-the-blank exercises rather than simple flashcard recall. Each grammar point has multiple example sentences, so you do not just memorize one sentence — you see the grammar used in different contexts across different reviews. This makes each review slightly slower than a vocabulary flashcard but significantly deeper. A 15-minute Bunpro session might cover 20-30 grammar points.

The practical takeaway is that both tools can be used efficiently in short daily sessions. A combined routine of 15 minutes on JLPTLord (vocabulary) plus 15 minutes on Bunpro (grammar) gives you 30 minutes of highly focused, SRS-optimized JLPT preparation each day. This is far more effective than spending the same time passively reading a textbook or watching videos.

Pricing Comparison

Both tools offer free entry points so you can try before committing. JLPTLord has a generous free tier that lets you study a substantial number of vocabulary words with full spaced repetition functionality. The paid plan unlocks all JLPT levels from N5 through N1 at an affordable subscription price — see our pricing page for current details.

Bunpro offers a limited free trial period and then transitions to a paid subscription. The annual plan works out to approximately $5 per month, while the monthly plan is approximately $8 per month. Bunpro occasionally offers discounts and has a lifetime purchase option that appears during sales events.

If you use both tools, the combined monthly cost is still modest — less than a single hour of private Japanese tutoring in most markets, and the SRS-driven approach ensures you are retaining what you learn rather than forgetting it between lessons. For serious JLPT candidates, the return on investment of having both vocabulary and grammar covered by dedicated SRS tools is substantial.

Pros and Cons

JLPTLord: Strengths and Limitations

Strengths: Comprehensive JLPT vocabulary coverage across all levels (10,000+ words). Clean organization by JLPT level with clear mastery tracking. Placement test saves time for intermediate and advanced learners. Multi-format word display (kanji, furigana, romaji, English) prepares you for every context. Generous free tier. Fast SRS reviews that fit into a busy schedule. The vocabulary focus means you are building the single largest component of the JLPT — the word list you need to know.

Limitations: JLPTLord is focused on vocabulary and does not teach grammar. You will need a separate resource (like Bunpro, a textbook, or a grammar reference) for grammar preparation. It also does not include listening practice or reading passages, though strong vocabulary knowledge significantly helps with both of these sections. For learners who prefer an all-in-one platform, the focused approach may feel incomplete — but that focus is also what makes JLPTLord exceptionally good at what it does.

Bunpro: Strengths and Limitations

Strengths: The only dedicated grammar SRS designed specifically for JLPT preparation. Comprehensive coverage of approximately 800 grammar points across all levels. Excellent example sentences drawn from multiple authoritative sources. The fill-in-the-blank format tests active production rather than passive recognition. Textbook path options (Genki, Tobira) for learners following a course. Nuance notes that distinguish between similar grammar points — extremely valuable at N2 and N1 where grammar distinctions are subtle.

Limitations: Bunpro does not provide comprehensive vocabulary coverage. While it has recently added vocabulary decks, these are limited and do not match the depth of a dedicated tool like JLPTLord. The grammar fill-in-the-blank format can sometimes feel ambiguous when multiple grammar points could technically fit a sentence. The learning curve is steeper than simple flashcard review — grammar SRS requires more cognitive effort per review session. There is no placement test, so learners must manually decide where to start studying.

The Power Combo: Using JLPTLord and Bunpro Together

The most effective JLPT preparation strategy is not choosing between these tools — it is using both. Here is a practical daily study plan that covers both vocabulary and grammar in under 45 minutes:

Morning (15 minutes): Complete your JLPTLord vocabulary reviews. The SRS will show you words that are due for review, and you can add new words from your target level. This session is fast and builds your word bank for the day.

Afternoon or Evening (15 minutes): Complete your Bunpro grammar reviews. Work through the fill-in-the-blank exercises, paying attention to the example sentences. Many of the vocabulary words you studied on JLPTLord that morning will appear in Bunpro's example sentences, reinforcing your memory.

Weekend (15 minutes extra): Add new grammar points on Bunpro and new vocabulary on JLPTLord. Review your progress dashboards on both platforms. Identify any areas where you are falling behind and adjust your daily load accordingly. If you are preparing for a specific test date, both tools let you see how much content remains so you can pace your study appropriately.

This combined approach means that when you encounter a reading passage on the JLPT, you have both the vocabulary to understand the words and the grammar to parse the sentence structures. Neither tool alone provides this, but together they cover the Language Knowledge section comprehensively. Pair this with listening practice and practice tests at your level, and you have a complete preparation system.

Who Each Tool Is Best For

Choose JLPTLord if: Your biggest weakness is vocabulary. You see words on practice tests that you do not recognize. You want to systematically learn every word at your target JLPT level. You already have grammar covered through a textbook, class, or Bunpro. You want a free option to start studying immediately. You need a placement test to skip vocabulary you already know. You learn best through efficient, focused study sessions.

Choose Bunpro if: Your biggest weakness is grammar. You understand individual words but cannot parse sentence structures. You want a dedicated SRS for grammar patterns. You are following a textbook (Genki, Tobira) and want a review tool that maps to your chapters. You are at N2 or N1 level where grammar nuance becomes critical. You want to practice producing grammar in context rather than just recognizing it.

Choose both if: You are serious about passing the JLPT. You want comprehensive preparation that covers both vocabulary and grammar. You have 30 minutes a day to dedicate to SRS study. You are targeting N3 or above, where both vocabulary breadth and grammar depth become essential. You want to build a study system that you can maintain consistently over months.

The Verdict

JLPTLord and Bunpro are not competitors — they are two halves of a complete JLPT preparation strategy. JLPTLord is the best dedicated vocabulary SRS for JLPT candidates, with 10,000+ words organized by level, a placement test, and efficient review sessions. Bunpro is the best dedicated grammar SRS for JLPT candidates, with 800+ grammar points, contextual exercises, and textbook integration. Neither tries to do what the other does best, and that focus is what makes each one excellent at its job.

If budget forces you to pick just one, choose the tool that addresses your weaker skill. If vocabulary is your gap, start with JLPTLord. If grammar is your gap, start with Bunpro. But for anyone targeting N3 or above — and especially for N2 and N1 candidates — investing in both tools gives you the most comprehensive SRS-based preparation available. The combined cost is modest, the daily time investment is reasonable, and the results speak for themselves: vocabulary and grammar are the two largest components of the JLPT, and having dedicated SRS coverage for both puts you in a strong position on exam day.

Start with JLPTLord's free tier to build your vocabulary foundation, add Bunpro when you are ready to systematize your grammar study, and complement both with listening practice and other tools as needed. This layered approach is how successful JLPT candidates prepare — not by searching for one perfect app, but by combining focused tools that each do one thing exceptionally well.
