A hook on Takanori Nishikawa’s (西川貴教) stage costume came undone mid-concert, and the T.M.Revolution frontman’s fans stepped in to cover for him, belting out an entire verse while crew members fixed the wardrobe malfunction, according to accounts shared by concertgoers on X (formerly Twitter).
The moment happened during the second verse of “HEART OF SWORD ~Yoake Mae~,” T.M.Revolution’s 1996 single that served as an opening theme for the anime Rurouni Kenshin. One fan who attended the show wrote that a hook on Nishikawa’s costume, which fans jokingly compared to a bra due to its chest-support design, came loose and needed attention from staff. Two crew members worked to fix it on stage while Nishikawa kept performing, and the audience carried the vocals for him during the repair.
Fans clarified in follow-up posts that the hook was a standard clasp rather than a front closure, and that it was successfully re-fastened rather than torn open. The anecdote quickly circulated online, with commenters joking about the amount of information packed into the story and praising the crowd for keeping the song going without missing a beat.
Who is Takanori Nishikawa?
Takanori Nishikawa (西川貴教) is a Japanese singer best known as the vocalist of the rock project T.M.Revolution, which he launched in 1996. The act became known for high-energy performances and anime tie-in songs, including “HEART OF SWORD ~Yoake Mae~” for Rurouni Kenshin and later themes for franchises such as Gundam SEED. Nishikawa has also organized the summer music festival teamLab Cross Salon and appeared frequently across Japanese television and radio over his three-decade career.
The wardrobe mishap added a lighthearted footnote to what fans described as an otherwise high-energy show, with the singer continuing the performance without missing a step once the costume was secured.
