Wearable devices, drones and talking robots are hot topics in the tech industry, and toy makers are trying to ride these trends with their latest offerings, the toy industry's annual trade show revealed Thursday.

This year's International Tokyo Toy Show, running through Sunday at Tokyo Big Sight in the Odaiba district, drew 149 Japanese and 19 overseas exhibitors.

The April debut of the Apple Watch brought a lot of attention to wearable devices, but many parents probably feel their children are too young to have such a device. Knowing that kids typically crave the same things as adults, Sega Toys Co. has created a smartwatch for the underage set, said spokesman Hiroki Goto.
