The $2,500 answer to Amazon's Echo could make Japan's sex crisis even worse

Japan has a sex problem. The country's birthrate is shrinking year after year, to the point where deaths are outpacing births.

Simply put, Japan's population is decreasing.

But let's be clear: Population change is a complicated subject affected by many factors.

Western media often correlates the decline in Japan's population size with recent studies of Japanese sexual habits and marriage. A 2016 study by the National Institute of Population and Social Security Research in Japan, for instance, found that "almost 70 percent of unmarried men and 60 percent of unmarried women are not in a relationship."

But just because people aren't in relationships doesn't mean they don't want companionship, of course. And that's where something like Gatebox comes in.

Yes, that is an artificially intelligent character who lives in a glass tube in your home. Her name is Azuma Hikari, and she's the star of Gatebox — a $2,500 Amazon Echo-esque device that acts as a home assistant and companion.

Here's what we know:

A Japanese company named Vinclu created the Gatebox.

It's about the size of an 8-inch by 11-inch piece of paper, according to Vinclu. And there's a good reason for that: The device is intended to be "big enough for you to be able to put right beside you." You'll understand why you'd want a Gatebox so close soon enough.

The Gatebox is similar to Amazon's Echo — it's a voice-powered home assistant.

The Gatebox has a microphone and a camera because you operate it using your voice.

For now, it will respond only to Japanese; the company making Gatebox says it's exploring other language options. Considering that preorder units are available for both Japan and the US, we'd guess that an English-language option is in the works.

Gatebox does a lot of the same stuff that Echo does — it can automate your home in various ways, including turning on lights and waking you up in the morning.
