Synchronised steps: Japan walking art tradition marches on

Shoes squeaking in perfect unison, dozens of Japanese students move in formation through a Yokohama sports hall in training for a synchronised walking performance expected to draw thousands.

For more than half a century, students at Nippon Sport Science University have captivated audiences with their intricate displays in a practice known as Shudan Kodo, meaning "collective action".

This year, more than 80 students are set to take part on December 6, after a rigorous training regimen across four months that prepares them for their performance walking forward, backward and sideways in flawless sync.

"In a world where self-centeredness is prevalent, I want people to learn compassion through moving as a group," said Jiro Omi, the walking squad's coach of more than 30 years.
