McDonald’s Japan is rolling out a special purple sweet potato shake for a limited time, promoted as autumn flavour, called “murasaki imo”.
This new McShake with a bright purple colour, advertised as an autumn flavour, is said to combine the richness of sweet potato with the texture of creamy milk.
The flavour is “murasaki imo” which means “purple sweet potato” in English. According to website Entabe, the purple shake will go on sale from September 10 in Japan and will be available till late October.
