The 18-year old will join Spurs in January pending his medical in South Korea.
Yang has been widely compared to Tottenham's current South Korean star and captain Son Heung-min.
Yang, dubbed by many as the 'next Son', has shone in the K League in 2024 and won the Young Player of the Month award in April, May and June.
The teenager has started all 24 of Gangwon's league games so far this season, producing seven goals and three assists.

Yang is set to become the third Korean player in the history of the Tottenham men's team.
The first was left back Lee Young-pyo, who represented Spurs 93 times between 2005 and 2008.
But Tottenham's most famous Korean player past or present is undoubtably Son, who has scored 162 goals in 408 games since his arrival in 2015.
Like Yang, Son's natural position is as a wide attacking player but he was used more centrally last season following Harry Kane's move from Spurs to Bayern Munich.
The current K League campaign will end on November 24.
With 15 rounds of fixtures remaining this season, Gangwon are currently placed fourth - just three points behind leaders Pohang Steelers.
Yang is likely to play against Ange Postecoglou's Spurs before he joins them.
That is because he has been selected to represent the K League in an all-star team that will take on Tottenham in an exhibition game in Seoul on Wednesday.
