Career
His highest rank was ōzeki. To meet the weight requirement, he had to drink an enormous amount of water prior to his physical. However, he was able to put on more weight as he moved up the ranks.
He reached the second highest jūryō division in March 1954 and was promoted to the top makuuchi division in March 1955.
After three years of steady progress he worked his way up to sekiwake rank and in the September 1959 tournament was runner-up once again. This performance earned him promotion to ōzeki.
In his ōzeki debut he took the tournament championship with a 13-2 record, the first ōzeki debutant to do so since Chiyonoyama ten years earlier. After the tournament a party was held at the Imperial Hotel to celebrate both his ōzeki promotion and his engagement.
Wakahaguro was expected to quickly push on to yokozuna promotion, but his second tournament as an ōzeki ended with an extremely disappointing 7-8 record.
After this it was clear that Wakahaguro had neither the consistency nor the determination to reach sumo"s highest rank, and he was to be overtaken by two younger rivals, Taihō and Kashiwado. In November 1960 Wakahaguro managed to defeat Taihō for the first time in five attempts but could not prevent him from winning his first championship. Wakahaguro"s 12-3 runner-up performance was the last time he was able to challenge for a tournament title.
After a poor 5-10 record in July 1961 he missed the September tournament through injury.
In November 1961, the same tournament in which both Taihō and Kashiwado made their yokozuna debuts, Wakahaguro lost his ōzeki rank after managing only a 5-10 record on his comeback. The rules in place at the time meant three consecutive make-koshi or losing scores would result in demotion, and his absences in September were counted as losses.
Wakahaguro spent the last three years of his career in the maegashira ranks, but he was beset by personal problems, including a gambling addiction. In 1965, heavily in debt, he was forced to retire in disgrace after being caught attempting to sell smuggled handguns to gangsters, which he had acquired in Los Angeles whilst on an overseas tour.
He was tried, convicted and given an 18-month suspended prison sentence.
A formal retirement ceremony was impossible in such circumstances so a private one was done quietly at a hotel in Miura city. He died suddenly of a stroke at the age of 34. The Kyushu tournament was first held in 1957, and the Nagoya tournament in 1958.
