The domestic swimming competition starts. Irie wins 30th birthday with good time.Jan 24 20:29

Ryosuke Irie, whose 30th birthday was on the 24th, marked a good time in a boy's 100 meter backstroke and won the championship, with the top competition swimmer participating in the domestic tournament.

At the Kousuke Kitajima Cup, which started at the Tatsumi International Swimming Pool on the 24th, many top athletes will participate in the Japan Olympic Championships in April, which will be the preliminary selection event for the Tokyo Olympics.

Irie, a silver medalist at the London Olympics who turns 30 on the 24th, passed the top qualifying session in a 100-meter backstroke on the first day, pulling the race from the beginning of the race in the first half of the 2009 Swim at a faster pace than the Japanese record marked in the year and won.

Although the time did not reach the Japanese record, it was a good time of 52.59, which is the silver medal of the world championship last year.

Irie was based in the United States after the last Rio de Janeiro Olympics, but returned to Japan last year and reviewed onshore training with a specialized trainer.

Irie said, "I am relieved that I have a good time to review my training, but I am not satisfied with this, I can not get a medal. I just want to tighten my mind thinking that it is a passing point."

In the Men's 200-meter Freestyle, Katsuo Matsumoto, who won the silver medal at the World Championships last year, won with a time of 1:45:82.
