Japanese have a tendency to go against modernization in anything to do with food and home. Not so much in terms of the consumer, but more on the side of business. They’ll have created the robot purely with the aim of getting some advertising and once they’re done, they’ll throw the robot out without ever checking how well the chicken sold or whether it could be affordably mass produced.
There will probably only be the one machine and, if you know someone, you can probably get it as a gift once they’re done with it.
