The aging Japanese population presents a troubling problem when it comes burying loved ones. There's simply not enough room, and the room that is available costs about $20,000, according to Trends in Japan. So leave it to the Japanese to figure out a way to address the problem with a technological twist. Like a data tape-retrieving robot, Nichiryoku's interactive family plot system retrieves cremated remains from an underground vault and displays them to you in a private prayer area, courtesy of an RFID key. And yes, there's a series of promotional videos, complete with voices beyond the grave. Only in Japan, but unsurprising given the fact that QC codes adorn traditional grave stones already.
