Seven hundred and fifty miles from the train station near Yubaba's bathhouse; This island is filled with a deathly aura. The jungle strives with much effort to live, for its life has already depleted greatly. Poisonous gases accompany the ominous aura. The lake found in the center of the island, for which the island was named, has dark purple water; rather clear, but anything that touches this water dissolves instantly, with the exception of specially-made glass vials and the land that surrounds it. Spirits who are miserable enough for this death wish often jump into the Jisatsu Lake, disappearing forever.
