Similar theme songs (Dawn of the witch/ ONE PIECE)

I’ve recently been watching Dawn of the Witch and noticed that the ending theme(Imprinting by ED Full) sounds incredibly similar to the One piece opening (Hard Knock Days by Generations/ Exile)… I was wondering if anyone had any more information about the similarities… I honestly don’t know much about Japanese music other than anime theme songs, but I feel like there’s some kind of crossover here
