Japan is both the world’s third-largest media market and third-largest e-commerce market. As one of the first markets to develop a full mobile e-commerce ecosystem circa 2001 to 2002, Japanese digital consumers are experienced and discerning; digital marketing campaigns are sophisticated, multi-layered labor of love. While growth is lower in this mature market, e-commerce is projected to increase by 12% in 2016, 11% in 2017 – emerging technologies are driving substantial growth. Programmatic spend across all devices has seen a 156% increase between 2012 and now, with mobile Programmatic spend expected to grow 174% between now and 2017. If you want to excel in a mature, refined media advertising atmosphere and reach savvy consumers with equally-savvy media plans, Japan is the place to be.
