Height, Weight & Measurements
As a sumo wrestler, Kaisei Ichirō possesses a remarkable physique that contributes to his prowess in the ring. In 2025, his height is recorded at 6 feet 3 inches (191 cm), and his weight fluctuates around 440 pounds (200 kg). His body measurements reflect the athletic build required for successful competition in sumo, showcasing strength and agility.
Kaisei moved through the lower divisions quickly, reaching the fourth highest sandanme division in March 2007. He was promoted to the third makushita division after the March 2008 tournament, but then his progress stalled somewhat.
He came through the September 2009 tournament undefeated (although he lost a playoff for the yūshō to Gagamaru) and in July 2010 became a sekitori by earning promotion to jūryō.
He was the fourth Brazilian to make the jūryō division after Ryūkō, Kuniazuma and Wakaazuma, but Kaisei was to surpass all of them by winning promotion to the top makuuchi division.
After winning the jūryō division yūshō in November 2010 with an 11–4 record, he followed up with an 8–7 at jūryō 1 in January 2011, which saw him reach maegashira 16 in the May Technical Examination tournament. Kaisei won his first six bouts in his makuuchi debut, the first makuuchi debutant to do so since Takanonami in 1991.
He went on to 8–0, the first to achieve that since Sadanoumi in 1980, and 9–0, running neck and neck with yokozuna Hakuhō, before suffering his first defeat to Tochinoshin on Day 10. He thus failed to emulate the great Taihō, who reached 11–0 in 1960. Nevertheless, his final score of 10–5 saw him win the Fighting Spirit Award.
He was also given the honour of serving as Hakuhō's tsuyuharai, or dew sweeper, during the yokozuna's ring entering ceremony.

As of 2025, there are no confirmed reports about a girlfriend or boyfriend, leading to speculation among fans about his relationship status.

Kaisei often expresses gratitude towards his family for supporting him in his journey, and it is understood that they play a significant role in his life.
In his childhood, unlike his friends Sugano had no interest at all in football, not even watching games on TV. He was more interested in grappling sports, such as judo, which he practiced for a time. When he was sixteen a friend of his father's suggested that his already large size would be very suitable for sumo.
Sugano used to train in many sumo clubs in São Paulo, where he ended up meeting the retired rikishi Wakaazuma Yoshinobu, who is also Brazilian. Yoshinobu would strictly train him, knowing that as Sugano wanted to become a professional sumo wrestler, he should be severe on Ricardo's training.
Despite the difficulties, he continued to go on the trainings and commented about his dream of becoming a rikishi, as he was not able to see another career path he could take in Brazil. He began pursuing sumo and went on to win the All Brazil amateur sumo championship in the free weight category.
At this time he believed that, at least in Brazilian amateur sumo, all one needed was size and power to win, and decided to travel to Japan to try out sumo. He was introduced to Tomozuna stable by Wakaazuma and joined the stable in 2006. The stable was already home to another Brazilian wrestler, Kaishin.
He was given the shikona or ring name of Kaisei Ichirō. Ichirō was the name of Kaisei's late grandfather, who was Japanese.

His performances in the ring have garnered him acclaim, and he continues to be a fierce competitor in tournaments.
In terms of business ventures, there are indications that Kaisei may be exploring opportunities beyond sumo, possibly in merchandise or fitness-related enterprises. His experience and popularity make him a sought-after figure in promotional events and endorsements.
He was promoted to maegashira 5 for the July tournament, where he recovered from 1–4 to go to 6–4, but then lost his last five matches to finish on 6–9. With the intai-zumo (retirement from sumo) of ōzeki Kaiō during the same tournament Kaisei become the heyagashira (the highest ranked wrestler) at Tomozuna stable.
Disappointing scores of 4–11 and 6–9 in September and November 2011 saw him fall to the bottom of the division. A 5–10 record in the January 2012 tournament meant he suffered demotion to jūryō in March, but he produced a 10–5 record in Osaka, ensuring a return to makuuchi.
In July 2012 he scored eleven wins, picking up his second Fighting Spirit Award and earning promotion to maegashira 1. In September he just fell short with a 7–8 record, losing to Hōmashō on the final day. Since then he has largely alternated winning and losing tournaments.
Though he has proven his longevity in the top division, it remains to be seen whether he can achieve more consistent performances. He was not able to defeat a yokozuna even after 37 attempts.
