At the end of the 1980s, a new golf course opened in Yamanashi Prefecture in Japan. The golf course manager tried to use crows to collect lost balls, but soon after opening, a tragic accident occurred. After 30 years, a system has been developed to track the whereabouts of golf balls hit on the golf course, and people now enjoy golf using their smartphones. The system has been introduced all over the country, and golf courses equipped by the system are now called “digital golf clubs”. Foreign IT companies, which had noticed the trend of IT companies entering the golf industry, began to hold “Digital Golf Championships” with female professional golfers. The simple dream of amateur golfers to have a device that automatically tracks the ball they hit came to fruition in the form of a new type of golf course called a “Digital Golf Club”. It was born, grew, and was taking root in people's hearts, wavering between digital (machines) and analog (humans) against the backdrop of modern society.
