One mark per athlete — the athlete's best while representing Japan. Equal marks share a rank ("1=" style). An athlete with marks for two nations appears under each nation represented at the time (e.g. Obikwelu under Nigeria and Portugal).
About this derivation
These lists are derived from the marks in our database — including the complete legal all-time lists imported from alltime-athletics.com — grouped by the nation the athlete was representing at each mark. They are not official national records: federations ratify national records under their own eligibility rules, and some marks here may not qualify.
