Two online services using technology to allow grandparents to overcome the distance between them and their grandchildren are proving popular in Japan.

One is provided by Mago Channeru (Grandchildren Channel), introduced by Tokyo-based startup Chikaku Inc. in 2016. Using the technology, relatives can watch on their televisions high-quality images and videos uploaded via the company's application with a simple click of a remote control.

The system's main draw is that users can simply plug the device into a TV with a single cable, and it does the work of downloading pictures and videos.
