Location from Demon Slayer by Koyoharu Gotouge
The hidden settlement where every Nichirin blade is forged — its location is the Corps' most guarded secret, because without its smiths, no demon slayer carries a weapon.
The Swordsmith Village exists in a state of productive isolation. Its entire population is devoted to one craft: forging the Nichirin blades that are the only weapons capable of killing demons. The smiths are eccentric, obsessive, and irreplaceable — losing even one represents a significant blow to the Corps' combat capability. The village has a peaceful, almost timeless quality — hot springs steam, hammers ring, and craftsmen argue about blade technique with the intensity of religious scholars. This tranquility is deliberately maintained: the village's location is the Corps' most classified secret. Visitors are transported blindfolded, and no maps show its position. When Upper Moons Hantengu and Gyokko attacked, it was the worst security breach in Corps history.
A secluded mountain village built around forges and hot springs. Wooden workshops with constantly smoking chimneys line narrow streets. The ring of hammers on metal is the village's heartbeat. Natural hot springs steam between buildings, used both for bathing and for tempering blade metal. Surrounded by dense forest with wisteria borders. The village is difficult to reach — visitors are blindfolded and transported by Kakushi to prevent anyone from learning the route.
