Amatsu Dungeonhttps://irowiki.org/wiki/Amatsu_Dungeon

In the land of Amatsu, deep in the heart of Himezi Castle, lays a shadowy secret. Rumor has it that there is a hidden entrance that leads to a mysterious series of dungeons. The first of these is the Tatami Maze, a deceptive labyrinth of endless tatami and rows upon rows of rooms. None of what you see here are real, but many have been misled to believe otherwise and have since been aimlessly walking into dead ends. The second is the Battlefield in the Underground Forest, a cavern where many battles have taken place. And the last is the Amatsu Underground Shrine. There have been rumors (in hushed tones) on what lies in the Haunted Shrine, but no one has ever discovered what it was. All that is known is that the place has been sealed, and the ominous aura it exudes could ward off even the most courageous of warriors. The last level of the dungeon is where the MVP Boss Incantation Samurai or Samurai Specter resides.

Access to Amatsu Dungeon must first be acquired from the Feudal Lord by completing the Amatsu Dungeon Entrance Quest. Speak to the Soldier NPC (ama_in02 115,177) located on the 5th floor of Himezi Castle to enter the first floor of the dungeon, the Tatami Maze. The Feudal Lord Permit must be in inventory to enter the dungeon.

Alternatively, by doing the Amatsu Blue Harvest Quest until step 5, the player will get teleport access to the end of Amatsu Dungeon 1, thus skipping the Tatami Maze.
