Japan's Kento Momota tops men's singles ranking for the first time
Kento Momota has capped a superb 2018 by becoming the first Japanese man to reach number one in the badminton world singles rankings.
Momota's rise to the top came despite him going down in the final of the China Open last Sunday.
The 24-year-old was quick to thank his team and his supporters, saying on social media, "Number one in the world! It is really thanks to the support of people around me.
"I will do my best in the future! Thank you for your support."
But he will not strengthen his grip on top spot this week having handed a walkover to fellow Japanese Kenta Nishimoto in Friday's Korea Open quarter-finals.
Reaching the summit
Last month, Momota became Japan's first men's singles world champion in Nanjing.
After celebrating his 24th birthday, Momota followed up with a triumphant homecoming at the Japan Open in Tokyo.
The shuttler also reached the final of last week's China Open but went down in the final to unseeded Indonesian Anthony Sinisuka Ginting who also beat him at the Asian Games.
After becoming world junior champion in 2012, Momota announced himself as a top senior player in 2015 with BWF Superseries titles in Singapore and Indonesia.
The left-hander then beat Viktor Axelsen to claim the World Superseries Finals in Dubai.
But in April 2016, days after defeating Axelsen in the India Open final, Momota admitted frequently visiting an illegal casino in Tokyo.
Had the charges reached a criminal court, he faced up to three years in prison.
But the Nippon Badminton Association agreed not to press charges if Momota accepted a one-year ban from international competition which would see him miss Rio 2016.
Momota told FirstPost.com in June 2018, "I was immature and foolish. I readily accepted the compromise solution, and felt I richly deserved it.
"That one year in the wilderness was the darkest period of my life." - Kento Momota speaking in June
Momota returned to action in April 2017 and played on the Challenger circuit as he did not have enough ranking points to take part in SuperSeries events.
And having worked hard on his game and his fitness, Momota made a hugely successful return to badminton's top echelon in 2018.
A year to remember
At the end of April, Momota showed his trademark athleticism and ability to change defence into attack instantly as he stunned Olympic champion Chen Long in the final of the Asian Championships in Wuhan, China.
A month later, he beat Axelsen again as Japan put out Denmark in the semi-finals of the Thomas Cup.
Momota then made it back-to-back wins over Chen, but Japan went down 3-1 to China and had to settle for second place in the world team championship.
On the BWF World Tour - which replaced the Superseries this year - Momota was unable to overcome home favourite Lee Chong Wei in the Malaysia Open final.
But he went one better in July's Indonesia Open, beating Axelsen yet again, before securing his first world title against Shi Yuqi.
Japan is now challenging China for the title as badminton's premier nation with the women possessing greater strength in depth.
The omens are good for Tokyo 2020 with genuine chances of gold in both singles' events.
They will also be in the medal hunt in doubles with Misaki Matsutomo and Ayaka Takahashi the women's champions from Rio 2016.
Mayu Matsumoto and Wakana Nagahara won the women's doubles at this year's World Championships with Takeshi Kamura and Keigo Sonoga runners-up in the men's doubles.
