Tsuruga was also unsuccessful in the other three jumping competitions of the 1979/80 Four Hills Tournament . In his first competition after the tour in his home town of Sapporo , he reached 6th place in the first competition and 4th place in the second competition, the highest individual placement in a World Cup competition. In the following season he appeared again unsuccessfully in the Four Hills Tournament . Since he could no longer achieve any successes on the tour and only ended up in the rearmost places, he subsequently ended his active ski jumping career.
