I always enjoyed watching Nozomi Okuhara and Akane Yamaguchi play. Great speed, skills and fighting spirit.
I hope Shimoda, Asuka Takahashi, Gunji can inherit the wonderful skills, speed and fighting spirit.
I am quite impressed with Minoru Koga, Shimono and Koki Watanabe even though they did not win. If Minoru Koga was not tired out after the match with Nishimoto, he might be a threat to Tsuneyama.
Tanaka and Naraoka, I have to wait and see.
Tsuneyama has also improved a lot in his attacking skills if I am correct. He used to be mostly defensive. Also, there is hope in Nishimoto if he can develop stamina. Some may feel that he should not smash too much. But I think his smashes can be his strong point. The only problem is for players who must depend on smashes , they must also be ready to build up stamina. Because once stamina is gone, accuracy will also go along with it. Unforced / forced errors will creep in. If they are willing to build up stamina then by all means , go ahead and play that style that demand you to take every opportunity you can to apply smashes. Also, these type of players must try to win the match in first 2 sets and try to avoid going into the 3rd set. Playing Momota's style might not suit everyone especially if you meet some like Momota who is close to mastering his own style.
But Momota is indeed a very balanced player. Even when he smashes you can sense that he uses less energy to execute them than most players. Yet, it can be powerful and effective. Sometimes his smashes kills or score points and sometimes his smashes just put his opponent under pressure. Those who choose to play Momota's style must have very great internal control. He is patient, calm, alert, good instinct ... but not without speed, skills, accuracy and power to back him up so he can cope with the different types of challenges he faces.
Although I believe Momota will have great chance of winning but Players like Viktor Axelson, Ginting and Lee Zee Jia will be good challengers ... and by playing with these palyers .. it will help Momota to improve even more.
