• Synonym事象じしょうWrittenWritten/formal prose for events or matters, focusing on the event itself; also a probability-theory term, as in 「事象を分析する」.
• SynonymフェノメノンWrittenA loanword that is rarely used in Japanese; say 「現象」 in everyday contexts.
• Antonym本質ほんしつWrittenWritten/formal prose for the essence of a thing; it stands opposite 「現象」 as inner essence versus surface appearance.
• Antonym実体じったいWrittenWritten/formal prose for an actually existing entity or substance; it contrasts with 「現象」 as substance versus outward appearance.

Use 「現象」 for anything observable, in daily talk and academic writing alike. Choose 「事象」 in formal prose when the event or matter itself is the focus. 「本質」 and 「実体」 are opposites — inner essence and substance rather than what appears.
