Sixteen-year-old Rikako Ikee became the first woman to win five titles at the national swimming championships after sweeping the 50-meter freestyle and the 100 butterfly Sunday.

On the final day of the four-day meet, Ikee won the 50 free in 24.57 seconds before taking the 100 fly in 57.39. Through Saturday, the second-year high school student had topped the 100 and 200 free as well as the 50 fly, and met the qualifying standard for this summer's world championships in all five races she won.

Kosuke Hagino, who won the 200 backstroke on the final day for his fourth victory of the competition, is the only male to have won five national titles in a single meet. Kanako Watanabe and Tomoko Hagiwara had shared the record with four before Ikee's feat on Sunday.
