Japanese conjunctions are one of those things that quietly hold your sentences together, and once you actually acquire them, your reading and listening comprehension takes a noticeable step forward. I spent a long time treating them as background noise, just particles and connectors I'd sort of absorb eventually, and that was probably a mistake. Getting deliberate about these nine conjunctions, from the basic hiragana-level ones up to kanji-heavy JLPT N2 territory, changed how I processed native content faster than almost anything else I tried.
Why Conjunctions Are the Hidden Lever in Japanese Acquisition
Here's the deal: when you're reading a native Japanese text and you hit a conjunction you don't know, you don't just miss a word. You lose the logic of the whole sentence. Is this a contrast? A cause-and-effect? A condition? Without that connector, you're guessing at the relationship between ideas, and that's a tax on your comprehension that adds up fast.
I noticed this clearly when I started doing more immersion with long-form articles and dramas. My vocabulary was decent, but I kept getting tripped up not on nouns or verbs but on the little structural words binding clauses together. So I pulled back and got focused. Nine conjunctions, that was my entry point.
What most people don't know is that conjunctions in Japanese operate slightly differently depending on whether you're in casual speech, written prose, or formal register. Acquiring them in context, rather than just memorising a translation, is the difference between knowing a word and actually using it correctly.
The 9 Japanese Conjunctions You Need to Know
1. demo (but / however)
This is probably the first conjunction most learners pick up, and for good reason. でも (demo, but / however) sits at the start of a sentence to introduce a contrast or a counterpoint. You'll hear it constantly in casual conversation. Think of it as the everyday version of しかし (shikashi, however / but), which we'll get to in a second. If you've spent any time watching Japanese variety shows or slice-of-life anime, you've already heard demo hundreds of times without necessarily locking it in.
2. shikashi (however / but, more formal)
Shikashi carries more weight. It's the written, slightly more formal cousin of demo, and you'll run into it often in news articles, essays, and JLPT reading passages, especially at N3 and above. My tip is this: when you're doing reading immersion with news sources like NHK Web Easy, pay attention to how shikashi marks a shift in the argument. That pattern alone is worth noting.
3. dakara (so / therefore)
だから (dakara, so / therefore) signals a result or conclusion drawn from something stated before it. It's causal and it's everywhere in spoken Japanese. Ever wondered why native speakers can follow a conversation so quickly even when the grammar seems complex? Part of it is that conjunctions like dakara signal the direction of the sentence before you've even finished processing the clause before it.
4. nazenara (because / the reason is)
This one is a bit more deliberate. なぜなら (nazenara, because / the reason is) introduces an explanation, often followed by から (kara, because / from) or node at the end of the clause. It has a slightly explanatory, almost rhetorical feel, like you're about to lay out reasoning. You'll see it more in writing than in casual speech. It tends to show up around JLPT N3 level and it rewards learners who are already comfortable with basic sentence-final forms.
5. sorede (so / and then / as a result)
それで (sorede, so / and then / as a result) is softer than dakara. Where dakara feels like a logical conclusion, sorede often just moves the narrative forward, linking events in sequence. In storytelling or casual conversation, it's almost a verbal stepping stone. Picture this: someone telling you about their day in Japanese, stringing events together. Sorede is doing a lot of that connective work.
6. tokoroga (however / but unexpectedly)
This is one I underestimated for a long time. ところが (tokoroga, however / but unexpectedly) doesn't just contrast; it implies that what comes after was surprising or contrary to expectation. That nuance matters. In JLPT N2 reading sections, missing that expectation-reversal meaning can throw off your interpretation of the whole passage. Wait, there's more: tokoroga also appears in spoken Japanese, particularly in storytelling, which makes it worth acquiring through both reading and listening input.
7. mata (also / in addition / or)
Mata is versatile. Depending on context, it adds information, offers an alternative, or simply means again. At beginner level, learners often know mata as just the word for again, but its conjunction use, connecting parallel statements or adding a related point, is where it gets more interesting. No exaggeration: once you start noticing it as a conjunction in native material, you'll see it constantly.
8. tsumari (in other words / that is to say)
つまり (tsumari, in other words / that is to say) is a summarising conjunction. It signals that the speaker or writer is about to restate or clarify something in simpler or more direct terms. What I especially like about tsumari is how it functions as a comprehension checkpoint in native content. When you hear or read tsumari, you know a clearer restatement is coming, which is actually useful for learners trying to parse dense material. It tends to appear around JLPT N2 and in formal or semi-formal contexts.
9. taisite (in contrast / as opposed to)
Taisite marks a clear opposition between two things. It's more formal and shows up most often in written Japanese, academic or journalistic prose, and higher-level JLPT material. By the way, if you're targeting N2 or N1, taisite is exactly the kind of conjunction that distinguishes a strong reading score from a decent one, because it signals structure that test questions often ask about directly.
How to Actually Acquire These, Not Just Memorise Them
Flashcards have their place, but conjunctions are structural words. They need to be acquired in context, through repeated exposure to sentences where the logical relationship is clear. I'd suggest pulling example sentences from sources you're already using for immersion and tagging instances of these conjunctions as you encounter them. Sentence mining tools work well for this.
Did you know that conjunctions appear at a much higher frequency in formal written Japanese than in casual speech? This means your immersion sources matter. If you're only watching anime, you're getting heavy exposure to demo, dakara, and sorede, but you might be underexposed to tokoroga, taisite, and tsumari. Mixing in some native reading, even short NHK articles or blog posts, balances that out.
Basically, don't try to drill all nine at once. Work through them in rough order of JLPT level and frequency. Get the N4 and N3 ones solid first, then move up. The higher-register ones will start making sense through immersion once the foundational ones are locked in. That's how acquisition actually works, in my experience anyway.
Oh, almost forgot: pronunciation matters here too. Conjunctions like dakara and sorede are often reduced in fast natural speech. If you've ever watched a Japanese drama and felt like people were swallowing words, some of that is conjunctions being clipped. Training your ear to catch them in fast speech is its own separate step, worth doing alongside the reading work.
So if I could go back to the early stages of my Japanese acquisition and do one thing differently, it'd be getting deliberate about structural words like these much sooner. Vocabulary is the obvious target, grammar patterns get their due attention, but conjunctions sit in the middle and get quietly overlooked. That's worth correcting.
more Japan news on jpnerd.comFrequently Asked Questions
What level do I need to be to start learning Japanese conjunctions?
You can start with basic conjunctions like 'but' and 'so' as early as beginner level. The more formal and nuanced ones are typically covered in intermediate to upper-intermediate study, roughly equivalent to JLPT N3 to N2.
Is it better to memorise conjunctions from a list or learn them in context?
Context wins every time. Memorising a translation gives you a rough sense of meaning, but actually seeing a conjunction used repeatedly in real sentences is what builds the instinct to use it correctly. Reading native material and noting conjunctions as you go is one of the most effective approaches.
Do Japanese conjunctions work the same in spoken and written Japanese?
Not always. Some conjunctions are mostly found in formal written Japanese, while others are common in casual speech. Getting exposure to both reading material and spoken content, like dramas or podcasts, helps you build a feel for which conjunction fits which situation.
