180, which last year lost the global advertising duties for the sports brand Adidas to Sid Lee, was appointed after a competitive pitch process, which kicked off last summer.
The previous incumbent on Asics' advertising account was Amsterdam Worldwide.
As part of its Asics brief, 180 will launch products throughout 2011 and 2012. The agency will also launch a campaign later this year that aims to give emotional meaning and relevance to the Asics ethos of "Sound mind, sound body". It will run across TV and other channels, including digital.
Michael Price, the Asics European marketing director, said: "180 delivered an exceptionally strong strategic and creative approach to communicate our point of view.
"The Olympics is the ultimate stage to share our passion for sport."
