• SynonymはかないNeutralNeutral adjective for what is fleeting and illusory, tinged with a wistful sense of impermanence, as in 「儚い命」; 「一時的」carries no emotional coloring.
• Synonym暫定的ざんていてきWrittenFormal, written-style word for handling something provisionally until a final decision, as in 「暫定的措置」; 「一時的」only says the time is short.
• Related刹那的せつなてきWrittenWritten-style word for what vanishes in an instant, or for living only for the moment's pleasure, as in 「刹那的な生き方」; more emotionally colored than 「一時的」.
• RelatedかりそめWrittenLiterary word for something makeshift and short-lived, or careless and trifling; has an archaic flavor. 「一時的」lacks the nuance of carelessness.
• Related対症的たいしょうてきWrittenMostly medical: easing only the symptoms without touching the root cause, also used figuratively; 「一時的」says only that the time is short.
• Related苟且こうしょWrittenThe same word as the entry above, also written 「苟且」: temporary and perfunctory, or rash; more archaic than 「一時的」.
• Antonym長期的ちょうきてきNeutralNeutral and common: long-term, as in 「長期的な視点」; contrasts with 「一時的」in the length of time involved.
• Antonym恒久的こうきゅうてきWrittenWritten-style antonym: permanent and unchanging, as in 「恒久的な平和」; the direct opposite of merely temporary 「一時的」.
• Antonym永続的えいぞくてきWrittenWritten-style antonym: a state that lasts a long time, as in 「永続的な効果」; contrasts with temporary 「一時的」.

Use 「一時的」for something that lasts only a short time, as in 「一時的な措置」. Pick 「暫定的」for arrangements pending a formal decision, 「対症的」for treating symptoms only. 「刹那的」and 「儚い」add emotional color, 「仮初め」is archaic for makeshift or careless. Opposites: 「長期的」is the common word for long-term; 「恒久的」and 「永続的」are written-style words for permanent.
