The agency was appointed following a three-way pitch, and will run the business on a retained basis. PR work for the brand was previously handled by Casio Electronics' in-house team.
The agency is tasked with managing ongoing consumer work and a series of launches this year. The first of those products is Exilim - a credit card-sized 'wearable' camera.
PR work surrounding that launch will centre on highlighting Casio's efforts to move away from feature-laden cameras to compact and more portable models.
The agency will be attempting to generate word-of-mouth campaigns for Casio's cameras, particularly in the fashion, art, photographic and film-making industries.
JPR managing director Matthew Wood leads the agency's work on the account.
He said the agency's efforts would focus on Casio 'regaining ground' in the digital camera market.
The appointment is the second hire by Casio Electronics in as many weeks following the appointment of Slice PR to handle consumer work for the G-Shock and Baby-G watch lines last week.
JPR has also been appointed by Attic Futura to handle consumer PR for glossy women's monthly B magazine. The agency's brief includes work in Ibiza this month, and is aimed at driving sales of the title. JPR's work is headed up by director Fiona Jennings, reporting to B publisher Carrie Jimminson.
The wins follow the agency's appointment by British Airways to run a consumer PR effort surrounding the launch of the airline's reduced European fares.
