風来坊 is an evocative Japanese word for a carefree wanderer or drifter, someone who travels without settling down or following the usual path. Its literal imagery suggests a person who arrives like the wind, making it much more memorable than an everyday word for traveler.
In the song, the singer vows to become a 歴史に残る風来坊, meaning “a wanderer who will go down in history.” The phrase combines rebellious freedom with grand ambition, perfectly capturing the song’s defiant, adventurous spirit.
This is THE BLUE HEARTS at their most cheerfully reckless. The narrator says he got lost the moment he was born, "うまれた時に迷いはじめた" (I started getting lost the moment I was born), and he has no intention of fixing it: he doesn't trust a map or a compass, and he never bothered to remember the way home. The chorus line "どこへ行くのか" (where am I going?) keeps coming back, but it sounds more like a shrug than a worry.
His plan for life is to skip suffering over money and become a 風来坊 (a drifter who blows in with the wind) that history will remember, walking through a sleepless city full of crime with eyes that only look forward. Then comes the punchline of the title: "首つり台からうたってあげる" (I'll sing for you from the gallows) and "首つり台から笑ってみせる" (I'll show you I can laugh from the gallows). He calls himself a 100万ドルの賞金首 (a million-dollar wanted man, literally "a prize head"), asks to be dropped into hell when he dies, and dares you to "つかまえておくれ" (come and catch me). It is a cartoon outlaw fantasy, sung with a grin.
Learner tip: 〜ちゃないさ in 信じちゃないさ is casual speech for 信じてはいない (I don't believe in it), the kind of contraction you will hear constantly in Japanese rock.
