1. adverbexactly; precisely; just; right; opportunely; fortunately

2. adverbjust (like); as if; as though

• SynonymまさにNeutralMarks something as indeed the case or just about to happen, as in 「正にその通り」; leans written or emphatic, not the plain 'just' of 「ちょうど」.
• SynonymぴったりNeutralFits snugly with no gap or matches perfectly, and can also give an exact amount, as in 「サイズがぴったり」; more about a perfect fit than plain 'just'.
• SynonymまさしくWrittenRead 「まさしく」. Asserts that something is certainly, undoubtedly the case, as in 「正しく彼だ」; stresses firm identification, in written or formal prose.
• SynonymぴたっとCasualColloquial: for pressing close or stopping dead in an instant, as in 「ぴたっと止まる」; carries a momentary feel.
• SynonymドンピシャCasualSlangy: a direct hit, exactly what was expected or hoped for, as in 「ドンピシャのタイミング」; much more casual than 「ちょうど」.
• SynonymきっかりNeutralFor times and amounts exact to the last digit, not a hair off, as in 「三時きっかり」; narrower than 「ちょうど」, which also covers 'just like'.
• SynonymかっきりCasualColloquial twin of 「きっかり」 for exact numbers and times, also used of clear-cut boundaries; somewhat less common.
• SynonymちょっきりCasualColloquial: for amounts or times that match exactly; also the snip of scissors. Little used today.
• RelatedきちっとNeutralNeat and accurate with an orderly feel, as in 「きちっと並べる」; stresses tidiness rather than the 'just right' of 「ちょうど」.
• RelatedきちんとNeutralProperly, neatly, by the rules, as in 「きちんと片付ける」; it can mean accurately, but the focus is doing things right, not hitting a figure or time on the dot.
• RelatedきっちりNeutralExact with no gap, no more and no less; by extension thorough and scrupulous, as in 「きっちり払う」.
• RelatedズバリCasualColloquial: cutting straight to the point or hitting the mark dead-on, as in 「ズバリ言う」; also used when a guess is exactly right.
• RelatedちゃんとNeutralProperly, reliably, decently, as in 「ちゃんと食べる」; it can also mean exactly, but mainly judges whether something is done well.
• RelatedかっちりNeutralSnug with no gap, or firm and tight, as in 「かっちりしたスーツ」; it can mean precisely, but mostly describes a close fit or firmness.

For 'just' or 'exactly' in amounts and timing, 「ちょうど」 is the default. Use 「ぴったり」 for a perfect fit or match, 「きっかり」 when a time or amount is exact to the digit, 「きちんと」 for doing things properly and neatly, and 「まさに」 for 'indeed, just as...'. 「きっちり」 adds a snug, thorough feel, 「ちゃんと」 is about doing a thing properly, and 「ドンピシャ」 is slangy 'dead on'.
