It was reported on August 6th, 2019 by a Japanese news page ShareNewsJapan accuses BTS' Jungkook of showing anti-Japanese gestures by showing up at an airport in Japan while wearing a hanbok. The news site states that "Jungkook's arrival in Japan wearing a hanbok is a sign of the boycott of Japanese products". 

However, the article did not went unnoticed by the Japanese ARMY, who came to BTS' defense and retweeted the page over 2500 times, as well as leaving comments such as "this is ridiculous" and "this is absolutely a false news".

This is not the first time a right-winged Japanese media attempts to attack BTS regarding politics, as Jimin and RM were the most recent members that fell victim to such accusations.

BTS' recently has successfully completed their stadium tour in Japan, despite of the worsening relation between South-Korea and Japan, which once again proves their massive popularity within young people in the country. Therefore, it would natural that the Anti-Korean sentiments of Japan will do anything it can to bring down active Korean idols and artists within in its country.
