On November 4th 2018, Shibuya's public street will become a race track.

The world's top prosthetic athletes will participate in "Shibuya City Games ~The Challenge for the World's Fastest ~"?and attempt to set a new world record on a track created in the center Shibuya, on Fire Street.

The 60m world speed record is 6.34seconds.

To be the world's fastest is a human challenge in and of itself.
However, it is Sony's challenge as well.

The sight of the world's fastest athletes striving for new speed records before spectators' eyes on the streets of Shibuya, has the power to change people's outlook forever as they get a glimpse into the possibilities for people in the future.

What people envision as the future will soon become commonplace with the aid of technology.

Expanding humanity's possibilities for the future through technology.

Lower-limb prosthesis enable people who could not walk to walk again.
But is this technology of use only to those with disabilities?

Considered an oddity generations ago, eyeglasses today are a routine part of life, thanks to advances in lenses.
Anybody can wear glasses without the slightest self-consciousness or feeling of strangeness.
In a sense we can say that technology eliminated this problem.

A future in which everyone can walk, run and move.
A world without physical restraints.

Our aim is to make this future a reality,
expanding human possibility through technology.
Our challenge is to expand the future potential of humanity.

Researcher, Sony Computer Science Laboratories, Inc.
President and representative director, Xiborg Inc.

After graduating from Keio University with a master's degree, Ken Endo traveled to the United States. There he joined the Biomechatronics Group of the Massachusetts Institute of Technology (MIT) Media Lab, where he worked on the analysis of human physical capabilities and the development of lower-limb prosthesis. Currently he is pursuing research on expanding human physical capabilities using robot technology, as a researcher at Sony Computer Science Laboratories, Inc. In 2014, as representative director together with former track-and-field athlete Dai Tamesue and others, he established Xiborg, Inc, a company which develops lower-limb prosthesis for athletes and then trains the athletes along with their lower-limb prosthesis.
In 2012 he was selected by Technology Review, a science journal published by MIT, as one of that year's "TR35"-35 technological innovators aged 35 or under. In 2014 he joined the Davos conference as a Young Global Leader.

Superseding people's limitations to post new world records for the short-distance sprint: "running-specific prosthesis for athletes".

Prosthetic Limb for athletes

Challenge to set the world's fastest record with athletes wearing "Xiborg Genesis", a running-specific prosthesis for athletes, and the Xiborg ν ("Nu") is a lower-limb prosthesis with a radically new shape developed in 2018 as a successor to the Genesis.

Prosthetic Limb for athletes

In 2017, athletes with lower-limb prosthesis came to a stage in which they are able to compete on the world stage side-by-side with able-bodied athletes. "Xiborg Genesis" is a lower-limb prosthesis for athletes which was created by gathering the knowledges of a wide range of experts, including athletes, engineers, coaches and prosthetists. These lower-limb prosthesis are fashioned using carbon-fiber-reinforced plastic (CFRP). The rigidity of the plate springs is determined by a multitude of factors including shape, type of fiber used, and the thickness. The engineers have accumulated a vast store of expertise fabricating plate springs that satisfy rigidity optimized to the gait and body shape of each athlete. The Xiborg ν, developed just this year, is a lower-limb prosthesis for competitive athletes, born of analytical results from four Xiborg owners. This model uses large deformation to deliver mind-blowing propulsive power, while a higher center of gravity makes the shape easier to handle.

Event Report

Shibuya City Games ~The Challenge for the World's Fastest ~ 2018


November 4, 2018
Once Again, Shibuya's Public Street Was
Transformed into a Race Track

Public streets became a race track in the "Shibuya City Games ~The Challenge for the World's Fastest ~", a thrilling 60m race on Shibuya Fire Street. Taking place for the second time, the race pits nine of the world's top prosthetic athletes against each other in a series of thrilling qualifying rounds and a final race.

After fierce competition in the heats, there were three runners that advanced to the final round. Jarryd Wallace of the United States, wearing a lower-limb prosthesis from Xiborg, based on research from Sony Computer Science Laboratories Inc. (Sony CSL); Richard Browne, also of the United States and holder of the 100m world speed record at 10.61 seconds; and Felix Streng of Germany. The surrounding crowds on Fire Street erupted in cheers when the winner, for the second year in a row at Shibuya City Games, Richard Browne finished with a time of 7.24 seconds, just 0.9 seconds shy of the world record.

Between the qualifying rounds and the final race, three elementary school-age runners with lower-limb prosthesis took their first steps toward notching a world record by striving to beat their personal bests in the Challenge Run. Amid cheers of encouragement from the spectators lining the route, the school-age runners ran the same course alongside the world-class athletes while their faces were beaming with excitement.

From the stage, Ken Endo, Sony CSL researcher and Xiborg representative director, and Shinji Takahira, winner of the bronze medal in the 4 × 100m relay at the Beijing Olympics, provided running commentary, as they watched the race with Hiroki Ando, the event MC.
It was a full day of excitement and passion on the streets of Shibuya, vividly testifying to the amazing possibilities for humanity that technology makes possible.
