BTS's planned appearance on the Japanese music show "Music Station" has been postponed.
I can never accept the act that #BTS member wore the atomic bomb T-shirts humanely.
It also carries images of what appears to be a mushroom cloud created by an exploding atomic bomb, and of Koreans celebrating their liberation from Japanese rule in August 1945, the month the U.S. carried out nuclear attacks on Hiroshima and Nagasaki.
Japan, meanwhile, became the only nation to have experienced a nuclear attack when the United States dropped atomic bombs on Hiroshima and Nagaski killing an estimated 200,000-plus people at the end of WWII.
The seven-member boy band was scheduled to appear on TV Asahi's flagship music program, Music Station, Friday night.
BTS' recording company Universal Music said it will continue to support the band, but confirmed their appearance on Music Station had been cancelled.
There are conflicting reports as to when exactly Jimin wore the shirt.
BTS has said in a statement over the the row: "We apologise for disappointing fans who were looking forward to this".
Many have pointed out that while the controversy over the t-shirt design has been mentioned, another reason for the postponement may be the increasingly deteriorating relations between Japan and South Korea.
Ties between Japan and South Korea continue to be soured by bitter disputes over history and territory stemming from Japan's brutal 1910-45 colonial rule over the peninsula.
"I am a resident of Hiroshima, I will not allow BTS to appear on the music station".
"Don't be sad, this is not your fault, the [tense relations] between both countries is beyond your control".
"What's so wrong about Koreans commemorating National Liberation Day?" said another Korean user on Twitter.
Agreeing comments included, "I suddenly don't want to see IZ*ONE's faces", "Can't stand Mnet and CJ right now, just look at what they're doing", "That's messed up", "Mnet has got to feel at least some guilt right now", "Sorry IZ*ONE, I didn't really dislike you guys or anything before but now this is making me angry", "Can they just please ban IZ*ONE from KBS", etc.
Last month, Tokyo reacted furiously after South Korea's top court ordered a Japanese steel giant to compensate victims of wartime forced labour programmes.
