The 25-kilogramme (55-pound) statue, worth $5.25 million, was created from a mould of the star striker's foot by Ginza Tanaka to mark Messi's record-breaking fourth consecutive Ballon d'Or award.
The company said the golden foot is due to go on sale on Thursday, along with a number of miniature versions and a solid gold plate of the Barcelona frontman's footprint, the company said.
Part of the profits from the sale will go to help people affected by the quake and tsunami that hit Japan two years ago next Monday, through the Leo Messi Foundation, a charity run by the Messi family.
Argentinian Messi won an unprecedented fourth consecutive Ballon d'Or at a FIFA gala in Zurich in January, adding yet another record to his stellar list of achievements as the top scorer in Spain's La Liga.
