At this year's Tokyo Game Show, the big draw was next-generation 5G networking — setting pulses racing with the prospect of a radically more immersive gaming experience.

"It was very smooth, responsive and consistent," said Omar Alshiji, a 23-year-old game designer from Bahrain, after trying out the fighting game Tekken at the NTT Docomo Inc. booth.
