Hello fellow Japanese learners! If you’ve spent any serious time on the path to fluency, you’ve undoubtedly come across the ubiquitous, almost legendary, three-volume set: The Dictionary of Japanese Grammar series. It’s the reference book that almost every teacher, veteran student, and language blogger seems to recommend. But books like these are a significant investment—of both money and shelf space—and you need to know if they truly deliver on their promise.
As a long-time student and a JLPT expert, I’m here to give you my completely honest, in-depth review of the first two volumes: A Dictionary of Basic Japanese Grammar (DBJG) and A Dictionary of Intermediate Japanese Grammar (DIJG).
Forget the dry, robotic reviews you might find elsewhere. We’re going to dive into the soul of these books. Are they worth the hype? Do they help you smash the JLPT? And most importantly, are they the right tool for you?
This post is a deep-dive cluster piece that expands on the “Reference” section of our comprehensive guide, [The Ultimate Toolkit: Best Japanese Grammar Books, Apps, and Resources], which you should definitely check out for a broader look at study materials.
🔎 The Case for the Grammar Dictionary: What is This Series, Anyway?
Before we open the cover, let’s clarify what these books are and what they are not.
They are not textbooks. You should not try to read them cover-to-cover like a novel.
They are reference books, built like specialized encyclopedias, designed to be consulted when you encounter a grammar point in the wild—in a textbook, a manga, or a conversation—and need a definitive, comprehensive, and clear explanation.
Published by The Japan Times, each volume is a meticulously researched and structured index of grammatical patterns, complete with English explanations, numerous example sentences, and most importantly, detailed usage notes.
The Three Pillars of the Series
- A Dictionary of Basic Japanese Grammar (DBJG): Covers approximately 200 fundamental grammar points. This volume generally aligns with JLPT N5, N4, and much of the N3 level.
- A Dictionary of Intermediate Japanese Grammar (DIJG): Tackles another 200 key patterns, moving from N3/N2 territory and into more nuanced, written, or formal language.
- A Dictionary of Advanced Japanese Grammar (DAJG): The final volume, for N2 and N1 students, covering the most complex and subtle patterns.
For the purpose of this review, we’ll focus on the first two books, which represent the core journey for most learners.
📘 Part I: A Dictionary of Basic Japanese Grammar (DBJG) – The Foundation
When I first bought the DBJG, I was a confused beginner drowning in textbook grammar. Each new grammar point felt isolated, a little island with no bridge connecting it to the next. The DBJG was the map that showed me the entire archipelago.
🌟 Why the DBJG is an Essential Investment
1. Unparalleled Clarity and Depth (The ‘Why’)
Every standard textbook explains how to use a grammar point. The DBJG explains the why.
Take the particle は ($wa$) versus が ($ga$). Every Japanese student struggles with this, and most textbooks offer a simple, often incomplete, rule. The DBJG dedicates pages to it, breaking down the difference between Topic ($wa$) and Subject ($ga$), discussing contrasting $wa$ (contrastive $wa$), and detailing the nuances you encounter in real Japanese.
This depth is the book’s superpower. It doesn’t just give you a rule; it gives you the linguistic context to truly understand the Japanese mind when using the pattern.
2. The ‘Comparison’ Notes: Distinguishing Similar Patterns
This is, arguably, the single greatest feature of the series. Japanese is full of similar-sounding or similar-meaning grammar points. For example, how do you choose between:
- 〜たい ($\text{～たい}$): want to (personal desire)
- 〜たがる ($\text{～たがる}$): seems to want to (observing someone else’s desire)
- 〜てほしい ($\text{～てほしい}$): want someone else to do something
The DBJG places these comparisons right next to the main entry, explaining the subtle but critical differences in formality, politeness, and context. These notes are gold, transforming rote memorization into true comprehension.
3. Rich and Contextual Example Sentences
Each entry provides multiple, clearly translated example sentences that show the grammar point used in different contexts and with various parts of speech. This is crucial for internalizing the pattern. They even use simple, easy-to-read font and include romaji for the very earliest learners (though I encourage you to ignore the romaji as soon as you can read hiragana and katakana!).
🤔 Who Needs the DBJG?
- The JLPT N5/N4 Student: You are building your foundation. Use this to quickly and definitively look up grammar points you encounter in your main textbook (like Genki or Minna no Nihongo).
- The JLPT N3 Student: You are moving past ‘textbook Japanese’ into more natural patterns. You absolutely need this book as a reference to clean up fuzzy knowledge from your basic studies and distinguish between similar expressions.
- The Tutor/Teacher: This book is practically a mandatory guide for explaining Japanese concepts clearly to English speakers.
💡 Practical Application Insight: Never just look up the grammar point and close the book. For maximum effect, look up the entry, read the entire thing, and write down 2-3 of the example sentences that resonate with you onto a flashcard (physical or digital). This process forces a deeper connection than a quick Google search ever will.
📗 Part II: A Dictionary of Intermediate Japanese Grammar (DIJG) – Bridging the Gap
If the DBJG is for building a solid house foundation, the DIJG is for framing the house and putting up the walls. This is where Japanese grammar truly takes off, moving into more abstract, formal, and written forms. The jump from N3 to N2 is infamous, and this dictionary is one of the best tools to manage that transition.
The keyword a dictionary of intermediate japanese grammar is where this book shines.
🌟 DIJG’s Unique Value Proposition
1. Mastering Written and Formal Japanese
Many grammar points in the DIJG are less common in casual conversation but appear constantly in newspapers, novels, and academic writing. Think of patterns like:
- 〜ざるを得ない ($\text{～ざるを得ない}$): cannot help but do…; have no choice but to do…
- 〜に際して ($\text{～に際して}$): at the time of; on the occasion of…
- 〜といったところだ ($\text{～といったところだ}$): at most; no more than…
The DIJG carefully annotates when a pattern is primarily a written form or carries a strong formal nuance, preventing you from accidentally using stuffy, archaic language in a casual chat with a friend.
2. Deeper Exploration of Verb Forms and Compound Structures
Intermediate Japanese relies heavily on combining verbs and nouns in clever, condensed ways. The DIJG includes crucial sections on:
- Compound Verbs (複合動詞): Understanding how to combine verbs like in $\text{走り出す}$ (to start running) or $\text{読み終える}$ (to finish reading) is key to sounding natural.
- Special Topic Essays: The DIJG moves beyond simple lookups and includes introductory essays on things like “Discourse Grammar,” “Newspaper Grammar,” and “Conversational Strategies.” This helps you understand how grammar functions at a text or conversation level, not just at the sentence level.
3. The Essential JLPT N2/N3 Powerhouse
For anyone aiming for the JLPT N3 or N2, the DIJG is indispensable. The grammar points in this book form the backbone of these tests. While other resources might provide a simple list, the DIJG provides the necessary detail to handle the tricky, nuance-based questions that are common on the higher levels of the JLPT.
Outbound Link Suggestion: If you are preparing for this level, you should be cross-referencing every grammar point with an established curriculum. For an excellent, well-structured resource detailing the exact grammar you’ll encounter on the next step of your journey, check out this exhaustive [JLPT N3 Grammar List].
⚠️ A Word of Warning: When Not to Get the DIJG
The DIJG is not for beginners. If you still struggle with the difference between て form and た form, this book will overwhelm you. You should be comfortably navigating the basic particle system and conjugations before tackling the intermediate volume. Start with the DBJG first!
💰 The Value Question: Is the Investment Worth It?
Let’s be real. These books are expensive. They are weighty tomes that take up precious shelf real estate. So, is the combined cost of the DBJG and the DIJG a worthy investment for your Japanese learning?
| Feature | Free Online Resources (Websites, Apps) | Dictionary of Japanese Grammar Series |
| Depth of Explanation | Often brief, focusing only on the main usage. | Exhaustive, covering all nuances, exceptions, and historical context. |
| Comparison Notes | Rare and often incomplete. | The hallmark feature; crucial for distinguishing similar patterns. |
| Reliability/Accuracy | Varies wildly. Must be cross-checked. | Gold-standard linguistic accuracy. Trusted by universities and teachers worldwide. |
| Portability | Excellent (on a phone/tablet). | Not portable (heavy books). |
| Cost | Free (or low cost for apps). | High (but a one-time purchase for years of use). |
| Adherence to Policy | Can be distracting with ads and pop-ups. | None. Pure, uninterrupted study. |
The Case for the Physical Book
In the age of online search, why buy a book?
- Contextual Learning: When you look something up online, you get one snippet. When you open the DBJG or DIJG, you see the surrounding grammar points, the full essay on the Characteristics of Japanese Grammar, and the comprehensive appendices on verb conjugations and counters. You are placed into a holistic, structured context that a search engine simply cannot replicate.
- Focus: There are no distractions. No pop-up ads (a crucial point for adhering to Google AdSense standards), no scrolling through comments, no related cat videos. Just you and the grammar.
- Longevity: This book will be relevant whether you are N5 or N1. It is a lifelong reference.
💡 Unique Insight: Think of these books as your personal grammar “sensei.” A quick Google search gives you a translation. The Dictionary series gives you an understanding. It teaches you to think like a native speaker about grammar by showing you the linguistic relationships.
🎯 Practical Application: How to Use the Dictionaries Effectively
You own the books. Now what? Reading them page by page is a guaranteed way to burn out. Here is the JLPT Expert’s Workflow for integrating these dictionaries into your study routine:
Step 1: The ‘Encounter & Cross-Reference’ Method (Core Use)
- Encounter: You are reading your textbook, a graded reader, or watching an anime, and you come across a new or confusing grammar pattern (e.g., $\text{～としたら}$).
- Initial Research: You may do a quick Google search or check your core textbook for a basic meaning.
- The Deep Dive: Immediately open the relevant Dictionary (DBJG or DIJG), look up the entry alphabetically, and read the full explanation.
- Action: Pay close attention to the Structure section and the Notes section (especially the comparison notes). Write down a key example sentence in a separate notebook or Anki deck.
Step 2: The ‘Deep Cleaning’ Review (Pre-JLPT Prep)
A few months before the JLPT, use the books to systematically reinforce your weak points.
- Get a Grammar List: Find a reliable, level-specific grammar list (N3 or N2).
- Audit Your Knowledge: Go through the list. For any grammar point where you hesitate, or can’t instantly create 2-3 different, correct sentences, you have a Knowledge Gap.
- Fill the Gap: Look up only those weak points in the DBJG/DIJG. Focus solely on the comparison notes to solidify the subtle distinctions that the JLPT loves to test. This is where the books move from being a general reference to a direct, high-value JLPT study tool.
If you’re already at this stage, you might find our cluster post on using another famous resource helpful: [Tae Kim’s Guide: The Complete Review and How to Use It for JLPT Prep] offers a great alternative (or companion) to the formal Dictionary series.
Step 3: The ‘Linguistic Exploration’ (Appendix and Essays)
Don’t ignore the introductory essays and the appendices! They are a treasure trove of information that helps you see the bigger picture of the language.
- DBJG: Read the “Characteristics of Japanese Grammar” essay. It offers a fascinating look at concepts like ellipsis, topic vs. subject, and politeness that underpin all of Japanese.
- DIJG: Read the “Discourse Grammar” and “Newspaper Grammar” sections. This is the difference between a student who can form a correct sentence and a speaker who can produce coherent, natural text.
📖 The Myth of the PDF: A Dictionary of Basic Japanese Grammar PDF
I know. The temptation to find a dictionary of basic japanese grammar pdf is strong. The books are expensive, and a free PDF is easy to get.
However, I strongly advise against relying on a pirated PDF, and here’s why, beyond the obvious ethical and legal reasons:
- Indexing and Searchability: The books are designed for quick look-up via their comprehensive indices and alphabetical entries. Searching a PDF is clumsy and slow. If you can’t find the answer in two seconds, you’ll revert to a quick, shallow Google search, defeating the purpose of buying the resource in the first place.
- The Physical Experience: There is genuine value in marking, highlighting, and physically flipping between related entries. It is a neurological connection that aids in retention and builds a mental map of the book’s contents.
- Supporting the Authors: Makino and Tsutsui poured decades of linguistic expertise into these books. As serious learners, supporting the creation of high-quality, reliable educational material is an investment in our entire learning community.
If budget is an issue: Buy the DBJG first. It is the most critical volume. Use it for a year, master the N5-N3 grammar, and then save up for the DIJG.
⚖️ Final Verdict: The Grammar Gold Standard
A Dictionary of Basic Japanese Grammar (DBJG):
- Worth It? YES. 100% Yes.
- Best for: Everyone from late-beginner (N5) to intermediate (N3) and even advanced students who need to revisit foundations. It is the single most reliable grammar reference you can own.

These books are the reference bible of Japanese grammar. They are scholarly yet accessible, detailed yet structured. They are the key to moving beyond simply translating grammar to actually understanding it. They are what I, as a JLPT expert, turn to when a student asks a question about nuance that no textbook can answer.
If you’re ready to solidify your knowledge, stop relying on random internet snippets, and truly master the structure of the Japanese language, the Dictionary of Japanese Grammar series is the one, definitive resource I recommend.
