The 18-year-old centre-back will join the Bees B team set-up, and, subject to international clearance, will arrive at the west London club for the start of pre-season training on Thursday.
Kim recently featured for South Korea at the Under-20 World Cup in Argentina, helping the side to a fourth-place finish, and had been reportedly gaining interest from the likes of Bayern Munich and Sporting Lisbon.
Brentford director of football Phil Giles said: "Ji-Soo is an excellent prospect who was in demand from many teams in Europe this summer.
"He performed very well at the U20 World Cup recently, so it's a great credit to Lee Dykes and the recruitment team that we managed to sign him.
"We will give Ji-Soo all the time he needs to learn English, adapt to life in England and grow into our club in the B team, and like all of our B-team players he will earn the opportunity to train and play with the first team based on his performances."
