• Synonym怪しいあやしいNeutralThe most common word: suspicious, odd, or also uncertain. 「怪しげ」 focuses on how suspicious something looks from the outside.
• Synonym疑わしいうたがわしいWrittenWritten/formal: doubts about truth or likelihood, as in 「真偽が疑わしい」; a rational judgment, though 「疑わしい人」 also occurs. 「怪しげ」 is about the impression from appearance.
• SynonymいかがわしいNeutralCan mean suspicious or unreliable, but also indecent or improper, as in 「いかがわしい店」— a sense 「怪しげ」 does not usually carry.
• Synonym胡散臭いうさんくさいCasualColloquial: for someone or something of unknown origin you can't trust, as in 「胡散臭い話」; contemptuous, and carries more distrust than 「怪しげ」.
• Related不審ふしんNeutralSuspicion over specific doubtful points, as in 「不審な点」 or 「不審に思う」; 「怪しげ」 is about the impression of looking suspicious.
• Related変へんNeutralCommon in speech for something odd or off, as in 「変な人」; not necessarily suspicious, whereas 「怪しげ」 centers on suspicion.
• Related奇妙きみょうNeutralPuzzling and inexplicable, as in 「奇妙な体験」; can also describe suspicious-seeming words or behavior like 「奇妙な言い訳」, but need not imply distrust.
• Related異様いようWrittenWritten/formal: out of the ordinary, as in 「異様な雰囲気」, with an unsettling feel; not necessarily suspicious.
• Related不気味ぶきみNeutralEerie and unsettling, as in 「不気味な笑み」, often because you can't tell what something really is; the emphasis is on fear, while 「怪しげ」 stresses suspicion.
• Related奇怪きかいWrittenWritten/formal: bizarre and beyond common sense, as in 「奇怪な事件」; stresses the inexplicable, while 「怪しげ」 stresses looking suspicious.
• Related妖しいあやしいWrittenWritten/formal: mysterious and seductively alluring, as in 「妖しい魅力」. Unlike 「怪しげ」, it carries no suggestion of suspicion.
• RelatedうろんWrittenWritten/formal and rare: suspicious-looking with an unclear background, also disorderly. In everyday speech 「怪しい」 or 「怪しげ」 will do.
• Antonym確かなNeutralAntonym: certain and dependable, as in 「確かな情報」 — the opposite of the suspicious, unreliable feel of 「怪しげ」.
• Antonym明らかなNeutralAntonym: clear and plain at a glance — the opposite of 「怪しげ」, which suggests unknown origins and something you can't quite pin down.

For plain 'suspicious,' 「怪しい」 is the everyday choice; 「怪しげ」 describes someone or something that looks suspicious or of unknown origin, as in 「怪しげな男」. If distrust is the point, use 「胡散臭い」; for something reliable, 「確かな」. Many of the others stress oddness (「変」, 「奇妙」, 「異様」, 「奇怪」), eeriness (「不気味」), or doubt about facts (「疑わしい」) rather than a suspicious look.
