Confronting the simultaneous global economic stagnation that has resulted in diminishing consumption, a new driver which can instill in customers an exciting story with their own initiative and thrills them with gratification of consumption is essential. Japan's mobile phone driven innovation may provide a constructive suggestion to this requirement. On the basis of an empirical analysis focusing on the learning dynamism for innovative products in Japan's digital industry, this paper demonstrates the foregoing hypothetical anticipation. Based on measurement of dynamic learning coefficients for seven leading innovative products centered on mobile phones, the Granger causal test, Chow forecast test and wavelet analysis were conducted, and the significant role of mobile phones in leveraging broad dissemination, learning and absorption of core technologies essential to the advancement of digital industry was identified. Furthermore, significant role of demanding customers in inducing resonance between mobile phones learning and that of innovative products was demonstrated.
