Japanese Formal Connector Lessons

～にかわり marks acting on behalf of someone, or in their place, in a more formal written register. Formation is a person, role, or organization noun + にかわり, then the action you take for them: 校長にかわり、式辞を述べます. Treat it as the written style twin of に代わって. For object swaps or trade-offs, use 代わりに; for time or space spans, use にかけて.

～に関わる marks involvement, connection, or a matter that has a bearing—often stronger than mild “regarding.” Formation is a noun for a matter, person, or field + に関わる, used as a predicate or before another noun: 命に関わる, 環境に関わる研究. Prefer it when stakes, responsibility, or real connection matter; for soft topic-marking “about,” use について or formal に関して / に関する.

～に応じた is the noun-modifying form that labels something as suited to a prior condition, capacity, or request. Formation is a noun + に応じた + another noun: 予算に応じたプラン, 能力に応じた仕事, 年齢に応じた教材. Use it before a noun; for clause-level adapting before a verb, use adverbial に応じて instead.

～に沿った is the noun-modifying form that labels something as in line with a path, guideline, rule, theme, or expectation. Formation is a noun + に沿った + another noun: 方針に沿った改革, ガイドラインに沿った運用, 川に沿った遊歩道. Use it before a noun; for clause-level following before a verb, use adverbial に沿って instead.

～に基づく is the dictionary form that grounds a following noun—or a predicate—in a foundation such as data, law, facts, evidence, or research. Formation is often a noun + に基づく + another noun: 調査結果に基づく報告, 憲法に基づく権利, 統計に基づく予測. Use it to label something as founded on evidence; for "based on X, do Y" before a verb, prefer adverbial に基づいて.

～をきっかけに marks a specific chance, event, or opportunity as the starting trigger for a later change, habit, relationship, or new effort. Learners usually meet it at N3 in written Japanese, news-style narration, presentations, and careful polite storytelling about how something began. The part before をきっかけに names the trigger; the clause after it states what started or changed as a result.

～を中心にして marks a noun as the center that an action, organization, discussion, or arrangement revolves around. You attach it after a noun with を, then continue with the clause that describes what is organized, discussed, or arranged around that center. At N3 it is common in writing, news, reports, and careful spoken explanations, and it has close surface variants such as を中心に, を中心として, and を中心とした.

～をはじめ attaches after a noun and presents that noun as the first, main, or typical member of a wider group. After the connector, the sentence usually continues with other examples, a category label, or a predicate about the whole set—not only about the named item. You meet this formal connector often in news, reports, speeches, and careful explanations at the N3 level.

～をはじめとする is an attributive pattern that frames a following noun group as headed by a foremost or typical member. Formation is noun (A) + をはじめとする + noun (B): ピアノをはじめとする楽器, 医師をはじめとする医療従事者, 米をはじめとする穀物. Use it to label a set with A as the lead case; for a continuing list or predicate about the wider group, prefer adverbial ～をはじめ or ～をはじめとして.

～てからでなければ means B cannot happen, is not allowed, or is hard until A is finished first—especially in formal or written Japanese. Attach it after verb (te-form) + からでなければ, then follow with a blocked, negative, or difficult result. Keep it distinct from everyday ～てからでないと, sequential ～てから, and continuity ～て以来.

The Japanese grammar pattern ～あげく introduces what finally happens after a long, troublesome process—usually a regrettable or wasted-effort ending. Attach it to a verb in the ta-form or to a noun with の; optional に gives あげくに with the same feel.

～あげくに marks what finally happens after a long, troublesome process—usually a regrettable or wasted-effort ending, with に linking into the outcome clause. Attach あげくに to a verb in the ta-form or to a noun with の; the clause after it names the disappointing close.

～上は marks a settled premise—something already done or already true—and then forces a serious follow-through: obligation, determination, or a natural duty. It is highly formal and mostly written or ceremonial; attach it to V-た, the dictionary form, or noun and na-adjective with である.

～以上は marks a premise that already stands—an act done, a role held, a fact known—and then treats the next clause as a natural or justified follow-through: duty, resolve, judgment, or strong advice. Attach 以上は to V-た, the dictionary form, the ない form, noun or na-adjective with である, or an i-adjective; keep the second clause serious.

～から言って means “judging from that evidence” or “assessing from that standpoint.” It names a basis on the left—evidence, a result, experience, a situation, or a standpoint—then delivers a judgment or conclusion on the right. Formation is typically a noun or noun phrase plus から言って: 態度から言って, 結果から言って, 経験から言って, 私から言って. A judgment such as 反省していない, 成功した, or 無理だ often follows. Keep it apart from aspect-speaking ～からいうと, bare-judgment ～からすると, looking-metaphor ～から見ると, and part-to-whole emphatic ～からして.

～かと思うと marks a quick pivot from what just happened or what just seemed true to what follows right after—often sudden or contrary. Attach かと思うと after a plain clause: Verb (dictionary or ta-form), i-adjective, or noun or na-adjective plus だ. A factual sequel follows on the right. Compare formal ～や否や, near-simultaneous ～か～ないかのうちに, literary ～と思いきや, bare ～が早いか, and spoken twin ～かと思ったら—this lesson keeps the かと思うと surface primary.

～かと思ったら marks a quick pivot from what just happened or what just seemed true to what follows right after—often sudden or contrary. Attach かと思ったら after a plain clause: Verb (dictionary or ta-form), i-adjective, or noun or na-adjective plus だ. A factual sequel follows on the right. Compare formal ～や否や, near-simultaneous ～か～ないかのうちに, literary ～と思いきや, bare ～が早いか, and written-leaning twin ～かと思うと—this lesson keeps the かと思ったら surface primary.

～かと思いきや marks a sharp pivot from what you expected or briefly took as true to a contrary factual outcome. Attach かと思いきや after a plain clause: Verb (dictionary, ta-form, or ない-form), i-adjective, or noun or na-adjective plus だ. A factual sequel follows on the right. Compare twin ～と思いきや, spoken-leaning ～かと思ったら and ～かと思うと, and emotional ～のに—this lesson keeps the かと思いきや surface primary.

～といったら lifts a noun topic into an extreme-degree emotional peak: The speaker stresses how intense, amazing, or unbearable that quality is. Attach といったら after a noun, often a quality noun in さ or ぶり, then follow with a strong evaluation, ない, ありはしない, or なかった. Compare complaint-leaning ～ときたら, extreme-case ～に至っては, and neutral topic-shift ～といえば; this lesson keeps the extreme-degree といったら surface primary.

～といえば opens a topic by association: The speaker names something just mentioned or worth bringing up, then continues with a related remark. Attach といえば after a noun (or a short noun-like phrase), then add the association, memory, plan, or characterization that follows from that topic. Compare extreme-degree ～といったら, complaint-leaning ～ときたら, and fixed recall marker そういえば; this lesson keeps neutral speaking-of association primary.

～というと takes a word just named or heard and continues with the association, first image, or clarification that word triggers. Attach というと after a noun (or a short noun-like phrase), then add what that wording brings to mind, asks about, or defines. Compare speaker-led ～といえば, extreme-degree ～といったら, complaint-leaning ～ときたら, and fixed recall marker そういえば; this lesson keeps word-triggered association and clarification primary.

～ものだから gives a casual, defensive reason when the speaker wants understanding for a late arrival, mistake, or personal limit. Attach ものだから after a plain verb, i-adjective, or after な with a na-adjective or noun; the next clause states the result or soft request. Prefer ものですから in polite workplace talk; keep ～から for neutral reasons and せいで when blaming an outside cause.

～ものですから gives a polite, defensive reason when the speaker wants understanding for a late arrival, mistake, or personal limit. Attach ものですから after a plain verb, i-adjective, or after な with a na-adjective or noun; the next clause often apologizes, softens a request, or explains a careful exit. Keep ～ものだから and もんだから for casual familiars; use bare ～から for neutral reasons and せいで when blaming an outside cause.

～際 is a formal way to say when or at the time of an action or situation, common in manuals, notices, and careful workplace Japanese. Attach 際 after noun + の, or after a verb in dictionary or ta-form; the next clause often gives an instruction, requirement, or careful note. Keep everyday when as ～とき, reserve ～に際して for a special milestone, and treat ～際に as the same formal when with an added に.

～際に is a formal way to mark the time when an action or situation happens, common in manuals, notices, and careful workplace Japanese. Attach 際に after noun + の, or after a verb in dictionary or ta-form; the next clause often gives an instruction, requirement, or careful note. Keep everyday when as ～とき, treat bare ～際 as a close twin that often takes は, and reserve ～に際して for a special milestone.

～にあたり marks the formal occasion of beginning a planned event, role, or endeavor—common in speeches, notices, and careful written Japanese. Attach にあたり after a noun or after a verb in dictionary form; the next clause often gives a greeting, preparation, resolve, or careful request. Keep everyday when as ～とき, use broader formal when as ～際に, and treat ～に際して as a close milestone cousin that is more emotionally neutral.

～にあたって marks the formal occasion of beginning a planned event, role, or endeavor—common in speeches, notices, and careful written Japanese. Attach にあたって after a noun or after a verb in dictionary form; the next clause often gives a greeting, preparation, resolve, or careful request. Treat ～にあたり as a near twin with the same kickoff meaning; keep everyday when as ～とき and broader formal when as ～際に.

～に先立ち marks a preparatory step that comes before a formal event, ceremony, or planned process—common in speeches, notices, and careful written Japanese. Attach に先立ち after a noun or after a verb in dictionary form; the next clause usually names a check, briefing, rehearsal, or other setup. Treat ～に先立って as a near twin with the same “prior to” meaning; keep everyday before as ～まえに and kickoff occasions as ～にあたって.

～に先立って marks a preparatory step that comes before a formal event, ceremony, or planned process—common in speeches, notices, and careful written Japanese. Attach に先立って after a noun or after a verb in dictionary form; the next clause usually names a check, briefing, rehearsal, or other setup. Treat ～に先立ち as a near twin with the same “prior to” meaning; keep everyday before as ～まえに and kickoff occasions as ～にあたって.

～を前にして marks facing an upcoming event, person, or turning point—often with nerves, resolve, or reflection rather than a simple clock-time before. Attach を前にして after a noun; the next clause usually shows how someone stands toward that moment. Keep everyday before as ～まえに, preparatory formal steps as ～に先立って, and kickoff occasions as ～にあたって; keep approaching-date ～を控えて for calendar anticipation.

～を控えて marks that an important event or date is approaching on the calendar, and the next clause often shows lead-up preparation, busy atmosphere, or schedule pressure. Attach を控えて after a noun; do not insert の, and keep を (not に). Keep stance-focused facing as ～を前にして, preparatory formal steps as ～に先立って, and kickoff occasions as ～にあたって; keep everyday before as ～まえに.

～た途端 marks that the moment a verb action finishes, the next clause follows at once, usually as a sudden or unexpected result. Attach とたん after the verb ta-form. に may follow とたん, but the verb itself stays in the ta-form. Keep literary immediacy as ～や否や or ～が早いか, near-overlap as ～か～ないかのうちに, impression pivots as ～かと思うと, same-moment coincidence as ～と同時に, and a planned follow-up as the verb pre-ます form plus 次第.

～次第 marks that as soon as a verb condition is met, a planned next step follows. Attach 次第 to the verb pre-ます form, the part before ます. The right clause is often a future plan, report, or contact promise. Keep a sudden observed result as ～た途端, keep noun “depending on” as ～次第だ, and keep literary immediacy as ～や否や. Upcoming ～次第で and ～次第では stay comparison-only for now.

～次第で says that a result, a choice, or a difference depends on the noun before it. Attach 次第で directly to that noun. A clause can join with か or かどうか. Do not insert の before 次第. Keep a closing “it depends on” as ～次第だ, keep a marked possibility as ～次第では, and keep “as soon as” as the part before ます plus 次第.

～次第では says that one possible outcome depends on the noun before it. Attach 次第では directly to that noun. A clause can join with か or かどうか. Do not insert の. Keep a plain change as ～次第で, keep a closing “it is up to” as ～次第だ, and keep “as soon as” as the part before ます plus 次第.

～に伴い says that as one change or event happens, something else comes with it. Put a noun, or a dictionary-form verb, directly before に伴い. Do not insert の. Do not use ます or past た on that verb. に伴い is the part before ます of 伴う. News and notices use it. The right side may be a finished change, a change still going on, or a planned action.

～に伴う names a noun that comes with a change or an event. Put a noun, or a dictionary-form verb, directly before に伴う. The next word is a noun. に伴う modifies that noun. It does not join two clauses. News and reports use it.

～にしたがい says that as one thing changes, another thing changes with it, or that an action follows a rule, an instruction, or a guide. Put a dictionary-form verb, or a noun, directly before にしたがい. Do not insert の. Do not use ます or past た on that verb. にしたがい is the part before ます of したがう. Formal writing uses it. ～にしたがって is the more common て form with the same two uses.

～にしたがう means to follow or obey a rule, an instruction, a person's words, or a flow such as the changing times. The thing you follow takes に, never を. したがう changes like 買う: したがいます, したがった, したがわない, したがって. It can end the sentence or describe a noun, as in 法律にしたがった方法. ～にしたがい and ～にしたがって are the connectors that join two clauses.

～により is the formal, written form of ～によって. It gives a cause, a means, the doer in a formal passive, or a basis such as a rule, and it is common in news, announcements, and notices. 事故により、電車が遅れています means that the trains are running late due to an accident. Attach it to a noun, use ことにより after a clause, and use による before a noun. In conversation, で or によって usually sounds more natural.

ところが is a discourse connector that introduces what actually happened or is true when that outcome goes against the expectation created by the previous sentence or clause. It usually sits at the start of the contrasting sentence and is common in written narrative, news-style explanation, essays, and clear spoken storytelling. Learners meet it as a stronger, more expectation-breaking turn than casual でも, and as more tightly tied to surprise or discovery than broad written しかし.

では is a sentence-initial discourse marker that often means 'well then' or 'in that case' and moves talk or text to the next formal step. Learners meet it early in classroom Japanese, meetings, presentations, and polite service talk after some shared context is already clear. This lesson focuses on that transition use only; particle では, negative ではない, and casual じゃあ belong to different patterns.
