Kento Momota, Wakana Nagahara and Mayu Matsumoto became the first Japanese to repeat as badminton world champions on Sunday.
On the final day of the world championships, Nagahara and Matsumoto made history by defending the women's doubles title they won last year in China. The top seeds beat compatriots Yuki Fukushima and Sayaka Hirota 21-11, 20-22, 23-21 in 1 hour, 25 minutes in the day's first final.
Momota, the top men's singles seed, had little trouble with Denmark's Anders Antonsen, beating the fifth seed in 37 minutes 21-9, 21-3, and won all six of his matches without losing a single game to match his compatriots in the record book.
