Jason Yu is an esports and K-pop journalist, consultant, and video creator. He has lived overseas for 15 years, living in Japan and Korea for seven and a half years each.

Originally from California, he started his career as a software engineer after graduating college. After three years as a coder, he would leave his position and move to South Korea in 2010 to teach English. He would teach one year in kindergarten, teach university students English at Konkuk University and Sogang University for five years, and teach Computer Science at an international high school.

While working as a university instructor, Jason would also work as a journalist and columnist at Yonhap News. He would later work at Korea Times as a team leader and editor, mentoring Korean university graduates and coordinating stories with his Korean co-workers. He would also wrote for both publications in esports, Korean life, and K-pop.

During his journalist career living in Seoul, he would cover over 300 events as media. The genres he covered were film, anime, esports, J-pop, and K-pop. Among these events include the Busan International Film Festival, Tokyo Game Show, G-Star, the Bucheon International Film Festival, the Global Starcraft League, and the League of Legends Championships. Jason would work with several companies, including Livenation, JYP Entertainment, Starship Entertainment, 1totheK, Afreeca TV, Blizzard Entertainment, and Riot Games.

In late 2017, after living in Korea for seven and a half years, he would move back to California. He took a position as the West Coast K-pop writer at South China Morning Post (SCMP) and become an esports consultant to various companies.

He would create a new YouTube channel during this time called Popsori, a K-pop channel dedicated to learning Korean music in-depth. With the motto “become a smarter K-pop fan,” Jason wanted to share his K-pop media experiences while living in Korea, while teaching K-pop in a fun and educational way.

Today, Jason continues to create videos on Popsori, while working as a K-pop writer at SCMP and esports consultant in California.
