A robot made by QBIT Robotics can pour beer in 40 seconds and mix a cocktail in a minute. It uses four cameras to monitor clients in order to analyze their expressions using artificial intelligence (AI) software.

According to  Reuters, the government has eased visa restrictions to attract more foreign workers, but companies still face labor shortages as the population shrinks and the number of people over 65 increases to more than a third of the total.

For about 9 million yen ($ 82,000), the robot cost as much as the human bartender's work for three years.

Experts say the test of the bartender’s robot will last two months.
