The offending shirt featured the phrase "PATRIOTISM OURHISTORY LIBERATION KOREA" repeated multiple times alongside an image of an atomic bomb explosion and another of Koreans celebrating liberation.
The comments included, "The dropping of the atomic bombs led to the end of war, then liberation"; "It can not be swept aside simply by saying, "We wore it without knowing the meaning"; and, "I feel sad and pained that their chance to perform on the program is gone". "Music Station" stated on its official website, "A specific T-shirt worn by a BTS member caused a controversy, which was reported by media".
A controversy erupted recently over photos of BTS member Jimin wearing a T-shirt commemorating the day that Korea was liberated from Japanese colonial rule in 1945.
Back on November 8, TV Asahi's 'Music Station', abruptly "postponed" BTS's scheduled appearance on the popular music program, forcing Big Hit Entertainment to cancel BTS's flight to Japan on the same day and disappointing a huge crowd of fans who gathered at the airport to see the boys.
A BTS Japan fan site also announced their appearance had been postponed, along with an apology to fans who had been looking forward to the broadcast.
BTS member Jimin reportedly wore the shirt a year ago, on Aug 15, when Koreans celebrate the end of Japanese occupation in 1945.
It wasn't long before the Japanese words for #Unforgiveable and #AtomicBomb started trending on Twitter - and some Japanese social media users were furious. "We will work hard so that BTS can continue to meet their fans with better music and performances".
"Don't be sad, this is not your fault, the [tense relations] between both countries is beyond your control".
Tokyo reacted furiously in October after South Korea's top court ordered a Japanese steel giant to compensate victims of wartime forced labour programmes.
