RIO DE JANEIRO - Even he will be 31 in 2020, Japan's Kohei Uchimura does not want to miss the Tokyo Olympic Games.

"I want to be there," said the six-time all-around world champion, who defended his Olympic title at the Rio Games on Wednesday.

The 27-year-old Uchimura came from behind to win his second Olympic title in all-around, becoming the first man to achieve the back-to-back win in this event at the Olympics in 44 years.

Both Chinese finalists Deng Shudi and Lin Chaopan believed that the unbeatable all-around king had walked down from his peak, Uchimura didn't want to take a rest.

"My country is going to host the next Olympics. It's my duty. I want to be there," said Uchimura. "However, I would be 31. I would not be at my peak. What I think is, first of all, how I would be able to qualify? I would have to have a rest and give it a deep consideration."

"In the all-around I don't think I would be able to beat other people. I would have to select apparatus perhaps. But I want to take part. By that time my daughter would be old enough, so I hope I would be able to show her what her father can do."

The runner-up, Ukraine's Oleg Vernyayev said Uchimura was Michael Phelps in gymnastics, but the low-key Japanese believed that he was over flattered.
