Early Years & Family of Daiya Seto

On May 24, 1994, in Moroyama, Saitama, Japan, Daiya was born. Information about his parents and siblings is scarce.

Similar to that, he began swimming at the tender age of 5. In elementary school, he started competing in national swimming events.

He learned swimming and football as a child. However, he later discovered swimming to be more interesting and switched to swimming full-time.

Kosuke Hagino, a well-known swimmer, has been his rival since they were both young. However, for the childhood friends, a world rival is not an arch-enemy but rather an ally in a common cause.

In elementary school, the comrades initially connected at the summer national competition. Hagino, who was regarded as a “genius swimmer” in the public eye, lost the match.

Later, in the 400m individual medley, he triumphed over Haino. Later, the friendly competition evolved into friendship. Both have developed into top Japanese swimmers as of late, but their friendship is still strong.

Relationships, a Wife, and Kids with Daiya Seto

Yuka Mabuchi is the wife of Daiya Seto. Takahide Mabuchi, a well-known diving coach, is the father of Yuka Mabuchi. Member of the Japan Swimming Federation diving committee.

Head coach of the All Japan National Team. He is a naturalized Japanese citizen who was born and raised in China.

Yuka developed an early interest in swimming and diving, following in her father’s footsteps. At age six, she participated in her first Hikomi competition, a well-known diving competition in Japan.

She has won numerous medals in regional and national competitions. She did, however, announce her retirement after getting married to Seto.

Seto mentioned that she was tired of competing and desired something different for herself, even though she claimed that marriage had no influence on her choice.

They fell in love after meeting at a swimming competition. On May 24, 2017, Seto announced their nuptials via Instagram. On October 1 of that year, a lavish wedding reception was hosted at a hall in Toko.

Yuwa, the couple’s first child, was born on June 26, 2018. They were blessed with a second daughter in March 2020.

Social networking websites were used to announce both births.

Affair Extramarital Scandal

The beloved swimmer was the subject of a report published on September 23 by the Japanese news website “Daily Shinco,” which shocked fans.

According to that, Seto was alleged to have had an extramarital affair after being seen with his girlfriend in a specific hotel.

The following day, Seto came forward and admitted the charges. He then admitted to having a second, materialistic relationship and apologized to his loved ones.

But it wasn’t enough to stop the commotion. He allegedly had affairs with multiple women, not just one.

Sponsors and brands began to avoid Daiya after the upheaval. All of the advertisements that featured him were consequently removed.

Additionally, All Nippon Airways terminated his major affiliation agreement with them because “he was not worthy of corporate image” any longer.

Suspension

Seto immediately notified the Japan Swimming Federation and the JOC that he would be declining the position of team captain for the Tokyo Olympics.

The actions he took, according to Japanese swimming officials, were against the rules of sportsmanship and damaged the federation’s reputation.

Here are other dispositions imposed on Seto by the Japanese swimming federation: 

  • Suspension of activities within the year like participating in JSF official tournaments, training camps, overseas expeditions.
  • Suspension of recommendation of sports promotion fund subsidy in the second half of 2020.
  • Attendance on Future Japan Swimming Federation education program, JOC integrity education program, basic training program, etc.

Needless to say, he received widespread hate from Japanese fans, media, and the sports circle.

On the other hand, the world was surprised to see an athlete being harshly treated for a non-criminal offense like infidelity.

Japanese people have said that Japan is a country that values family and ethics very highly. Therefore, if anyone tries to overstep the boundaries, they are likely to be punished harshly.

Subsequently, Seto stated that he does not know how to apologize. Further, he states his apology is to continue swimming and restoring the trust of his family.

Yuka has not spoken anything about the affair yet.

While he was forbidden from participating in the next national games, he was allowed to participate in Tokyo Olympics and train in private.

He will also have to complete japan Olympic committees ‘integrity education’ and other courses.

Daiya Seto: Career

During high school, he was a three-time winner at 400m IM at the interschool championships.

He narrowly missed his chance at London Olympics after ending up third in the japan championships.

Though he was beginning his career, failing the trials had a negative effect on him. He felt a decline in motivation which was evident in his later performances.

Five months later, he won four crowns at the FiNa Istanbul.

The talented swimmer has won gold in 2012, 2014, and 2016 world short-course championships. Similarly, he has short course world records in the 200m butterfly and 400m IM.

Olympics 2020

All the swimming fans, including Seto himself, considered the Tokyo Olympics his major chance for redemption.

The reigning world champ in both the 200 and 400 IM, he participated in 3 events in the Olympics but only managed to reach the finals of 200m IM. He finished the race in 1.56.22, missing the bronze medal by 0.05 seconds.

It is not difficult to estimate that last year’s events have taken a major toll on his performance.

We can only wait and see how he manages to redeem himself and his career for the time being.
