Looks like he'll be ready according to this
report:
He initially returned to training a month after the accident but had to go for a surgery in Tokyo after complaining of having double vision. Fortunately, though, his problem has been fixed.
“He has been training with his club during this period and we’ve been monitoring him. He is in good shape and in fact, he looks more handsome than before, ” said Joo-bong with a smile.
“He took this opportunity during the lockdown to go for a plastic surgery. There are no scars whatsoever on his face.
“He has also been working out. According to our report, he has done well to control his body fat, in fact, his physical condition is better than before.
“He is now just waiting to resume centralised training, ” he said.
“If the situation is okay, our top players will probably start in September.
“Kento may not start by playing in three tournaments in a row, probably it will be the China and Japan Opens but we’ll finalise it all later.”
