双門洞（サンムンドン）界隈쌍문동

“ギフンの地元 — シリーズ全体を支える北ソウルの市場と坂の路地。”

あのシーンを再現: Gi-hun's world is the ordinary alleys — corner stores, steep steps, low-rise walls. Shoot at street level down an alley with power lines converging overhead and you have the show's visual grammar without needing any specific address.

現地のいま: This is a lived-in residential district, not a set: keep voices down, don't photograph into windows or open gates, and buy something at a corner store — the shopkeepers have seen a lot of pilgrims.
