Ryoji Watanabe set a new course record at Tokyo Tower on Sunday, becoming the first person to run the 500-step course in under two minutes.
Watanabe finished in a fantastic 1:59.98 to reach the top ahead of the chasing Takaaki Koyama.
The exciting event more than lived up to pre-race expectations, with a close race highly anticipated.
The in-form Koyama set a personal best 2:07.09 as he followed shortly behind Watanabe.
You can see the strong finish from both athletes in the video below.
Behind Koyama, Akie Yajima finished third in 2:10.13, with 2016 champion Naoya Endo in fourth. Hiroichi Uesugi finished in fifth place.
