Terao Tsunefumi (寺尾 常史, born as Yoshifumi Fukuzono 福薗 好文; 2 February 1963 – 17 December 2023) was a Japanese sumo wrestler.

Despite his relatively light weight he had an extremely long career, spanning 23 years from 1979 until 2002, and was known as the "iron man" of sumo.

To mark this promotion he changed his name to Genjiyama Rikisaburō, but reverted to Terao Setsuo after a single tournament.

However, he managed to return to makuuchi for two tournaments in March and May 2001, becoming at 38 years and 24 days the oldest man post World War II to earn promotion to the top division.

His last tournament was in September 2002, where he scored only five wins at the rank of jūryō 11 and faced certain demotion to the makushita division.

After being defeated by the 18-year-old Takahanada in March 1991, which he regarded as the most disappointing loss of his career, he was determined to keep fighting for as long as possible.

Terao was an oshi-sumo specialist, relying on pushing and thrusting techniques, keeping his opponent away from his mawashi.

He compensated by relying on his speed and agility, and was often able to use his quick reactions to outwit his heavier opponents.

Hōmashō retired in January 2015, but later in that same year Seirō became the second wrestler coached by Shikoroyama to reach the top division.

Sakahoko died in September 2019, and Kakureizan in March 2020, leaving Terao as the only surviving Fukuzono brother.
