• Synonym等しいひとしいWrittenFor quantities or degrees being equal, or being equivalent to something, as in 「死に等しい」. More formal than 「同じ」 and not a general-purpose substitute.
• Synonym同様どうようNeutralCovers situations that are the same or similar, as in 「前回同様」. It can mean roughly the same, and reads more formal than 「同じ」.
• Synonym同一どういつWrittenWritten and strict: for being completely identical or the very same one, as in 「同一人物」. Not for mere resemblance.
• Synonym同等どうとうWrittenWritten word for the same rank or degree, as in 「同等の権利」. It stresses equal standing rather than overall sameness.
• SynonymイコールNeutralLoanword meaning equals or identical, as in 「お金イコール幸せではない」. In speech it often frames a judgment; not a general stand-in for 「同じ」.
• Synonym均等きんとうNeutralFor even, equal distribution or opportunity, as in 「均等に分ける」. It targets balance across items, not overall sameness.
• Synonym同然どうぜんNeutralFor being virtually the same as, as in 「ただ同然」 or 「死んだも同然」. Often figurative; it asserts near-equivalence, not exact sameness.
• Related同質どうしつWrittenWritten word for having the same quality or nature, as in 「同質の材料」. Narrower than 「同じ」, which covers any kind of sameness.

• Related等質とうしつWrittenWritten term for equal or homogeneous quality, seen mostly in academic and specialist writing, rarely in daily use. 「同じ」 covers sameness generally.
• Related同じようおなじようNeutralSimilar, much alike, as in 「同じような服」; it makes no claim of complete sameness, so it is the looser, hedged way to say things resemble each other.
• Related類同るいどうWrittenWritten word for being of the same kind or similar. Very rare; keep 「同じ」 for everyday use.
• RelatedおっつかっつCasualColloquial word for being about even in degree, as in 「実力はおっつかっつ」. Casual speech only.
• Antonym違うちがうNeutralThe direct opposite of 「同じ」: to be different. It can also mean wrong or mistaken, a use 「同じ」 never has.
• Antonym異なることなるWrittenWritten antonym of 「同じ」, meaning to differ or vary. Choose it for formal prose over 「違う」.
• Antonym別べつNeutralAntonym of 「同じ」 for being separate or another one, as in 「別の日」. It marks a different item rather than a difference in quality.

For 'the same' in general, 「同じ」 is the default. Use 「同様」 or 「同じよう」 for roughly the same, 「同一」 for strict identity, 「等しい」 for equal quantity or degree, 「平等」 for equal treatment, and 「共通」 for what is shared. More specific options: 「同等」 for equal standing, 「イコール」 for equals, 「均一」「均等」 for uniformity, 「同質」「均質」「同質的」「等質」 for sameness of quality, 「等価」 for equal value, 「同然」 for as good as, and 「違う」「異なる」「別」 for the opposite.
