With the debut of high-end virtual reality gaming systems for home use, 2016 was heralded as the dawn of the VR era. But while the technology basked in the spotlight, some questioned whether there was substance behind the hype.

If this year's Tokyo Game Show is any indication, the technology is still hot.

During a media preview of Japan's biggest game event that opened to the media and businesses Thursday ahead of its public opening on the weekend, VR still appears to be a hot topic with people in the industry who say it has taken root over the past year with relatively solid sales of home devices and the emergence of specialized arcades.
