Jin, the oldest member of K-pop supergroup BTS, began his 18-month mandatory military service at a South Korean boot camp.
Dozens of fans and reporters gathered near the base on Tuesday, but the vehicle carrying Jin did not stop to let him out to meet them.
On Tuesday morning, Jin wrote on an online fan platform, Weverse, that “it’s time to raise the curtain.”
The 30-year-old posted a photo of his new military haircut, saying it “looks cuter than I expected”.
Six more band members will follow Jin into the military over the coming year.
Military service is compulsory for all able-bodied males between the ages of 18 and 28 in South Korea, with exemptions for athletes, traditional musicians and dancers.
The senior age was delayed for BTS in 2020, but it was announced in October that all group members will serve.
The band’s management agency said the band would reunite again around 2025.
In June, the stars announced they were taking a break pursue solo projects.
BTS, an acronym for Bangtan Sonyeondan – or Beyond The Scene – is a Grammy-nominated boy band formed in 2010.
In 2019, they made history as first Korean band to play at Wembley Stadiumwith their first sold-out party in 90 minutes.
