来歴|らいれきraireki[0]heiban (flat)

1. nounhistory; career

• Synonym履歴りれきNeutralA documented record of a person's or object's past — forms, logs, files. More modern than 「来歴」, and it points to the record itself rather than the story behind it.
• Synonym歴史れきしNeutralThe everyday word for history: how a society or thing has changed over time. Far broader than 「来歴」 and much more common.
• Synonym経緯けいいWrittenWritten/formal prose for the course of events — how a situation unfolded. It covers incidents and circumstances, not the history of an object the way 「来歴」 can.
• Synonym由来ゆらいNeutralThe origin or source of something — where it came from. Focuses on the starting point, while 「来歴」 traces the whole path since.
• Synonym由緒ゆいしょWrittenWritten/formal prose for a long, distinguished pedigree. Carries a positive, prestigious nuance that 「来歴」 itself lacks.
• Synonym沿革えんかくWrittenWritten/formal prose for an organization's development over time — company histories, institutional outlines. 「来歴」 is not tied to organizations.
• Synonym経歴けいれきNeutralA person's track record — schooling, jobs, positions held. Centered on people, where 「来歴」 can also cover the path of things.
• Synonym前歴ぜんれきNeutralOne's prior history or background. Note it is not 「前科」, which refers to criminal convictions.
• Synonym成り立ちなりたちNeutralHow something came to be and is put together — its makeup and origin. Focuses on formation, not the course traveled.
• Synonym来由らいゆWrittenA rare, written/formal word for the origin or cause of something. You will seldom meet it; 「由来」 is the everyday choice.
• SynonymヒストリーCasualColloquial loanword for history or a personal story. Often used as a catchy name or title rather than in ordinary description.
• RelatedキャリアCasualColloquial loanword for one's working career and professional experience — credentials built on the job, not a thing's history.
• Related素性すじょうNeutralOne's birth, lineage and identity — where someone comes from. Often in 「素性を隠す」; 「来歴」 is not limited to people's origins.
• Related過去かこNeutralThe past — bygone days, or a past someone would rather keep hidden. Much broader and more everyday than 「来歴」.
• Related年譜ねんぷWrittenWritten/formal prose for a chronological record of a life, year by year. It names the document, not the history itself.
• Related職歴しょくれきNeutralWork history as a résumé item — the jobs one has held. Narrower than 「来歴」 and tied to employment records.
• RelatedいわれWrittenWritten/formal prose for the reason or story behind something, including a traditional origin. Often seen in 「謂れのない」, meaning without grounds.

Use 「来歴」 for the course a thing has traveled or a person's background, as in 「故事来歴」 or 「来歴不明」. For a person's schooling and jobs, say 「経歴」; for origins, 「由来」; for a long, distinguished pedigree, 「由緒」. 「歴史」 is the everyday word for history at large; 「履歴」 and 「職歴」 point to records and résumé items; 「経緯」 covers how events unfolded; 「沿革」 traces an organization's growth.
