SG (age undisclosed), a half-Japanese, half-Korean singer-songwriter, performed his first Billboard Live Yokohama concert on the 20th. He sang her beautiful voice in the venue, which he chose as a "raw space to deliver her songs" to step up his game.

SG made their major debut in November 2011. With a unique style that mixes Korean, Japanese, and English, his music has been viewed more than 750 million times on YouTube and other platforms. On this day, they sang a total of 13 songs, including his song "Bokura Mata," which is popular as a graduation song for teenagers, and the cover song "March 9th."

After completing his first Billboard Live performance, which consisted of four performances in two locations, including the Osaka performance on the 13th, he said, "It was my first attempt, but the atmosphere was very homey." He was looking ahead to the next stage, saying, "I want to go to various places and perform live shows nearby."
