DIMSDRIVE carried out a survey at the start of December to find people’s views regarding electronic money. They interviewed by means of an internet-based questionnaire 6,430 people from all over Japan, 2,736 (42.6%) male, all members of their monitor group.
The Suica system comes out tops for name recognition, but that may be because it is promoted as not just electronic money, but more importantly as a rail pass. Suica is the preferred system for issuing railway season tickets, so it gets heavily promoted in that respect, and is also often featured on in-train advertising, therefore it has very high name recognition, as can be seen here.
However, Edy scores higher as the first thing that springs to mind regarding electronic money, perhaps because the advertising for Suica is weighted towards the season ticket features, not shopping.
