The 52nd annual International Tokyo Toy Show, which kicked off today at Tokyo Big Sight, is featuring 35,000 products from almost 150 companies from around the globe. Organizers estimate the four-day event will attract at least 160,000 visitors.

At a press preview on June 13, one notable trend was smartphone- and tablet-compatible games and interfaces. Some allowed players to interact with their environment and other gamers.

Another was the emergence of figurines and merchandise spinoffs from popular phone apps.

But the show clearly wasn't just for kids. Many companies showcased toys aimed at the child inside. And who knows? Maybe Ultraman, Sailor Moon and Mazinger Z can one day appeal to a new generation.

The Tokyo Toy Show is open to the public June 15-16. Admission is free.
