Fish-Man Island Location
Fish-Man Island One Piece is a pivotal location situated 10,000 meters below sea level, directly beneath Mary Geoise at the Red Line. It serves as the gateway to the New World for those who do not wish to cross the Red Line legally through the World Government. Enclosed in a massive double-layered bubble, the island is illuminated by the Sunlight Tree Eve, which transfers light from the surface to the ocean floor. This unique setting makes it one of the most visually stunning and geographically significant locations in the series, serving as the only underwater kingdom inhabited by Fish-Men and Merfolk.
Racial Themes
One of the most profound aspects of Fish-Man Island is its exploration of Fish-Man racism and the historical cycle of hatred between humans and Fish-Men. For centuries, the inhabitants of the sea have been subjected to discrimination, slavery, and prejudice by the surface world, particularly the Celestial Dragons. This narrative thread is personified through the contrasting ideologies of Queen Otohime, who sought peaceful coexistence and integration, and Fisher Tiger, who fought against the cruelty of human enslavement. The arc delves deep into the psychological scars of systemic oppression, showing how trauma can be inherited by future generations, as seen with the radicalized New Fish-Man Pirates.
Joy Boy's Promise
Fish-Man Island is home to one of the most important Poneglyphs in the series: a letter of apology from the mysterious figure known as Joy Boy. This letter, dated from the Void Century, expresses Joy Boy's regret for failing to fulfill a promise made to the people of the island and the then-mermaid princess. The nature of this promise involves the relocation of the island's inhabitants to the surface world. This lore is crucial to the overarching mystery of One Piece, as it suggests that the eventual "dawn of the world" is intrinsically linked to the liberation of Fish-Man Island and the fulfillment of Joy Boy's ancient vow.
Shirahoshi as Poseidon
A major revelation during the Straw Hats' visit is the true identity of the Ancient Weapon Poseidon. Unlike Pluton or Uranus, which are believed to be inanimate objects, Poseidon is a living person: Princess Shirahoshi. Poseidon Shirahoshi possesses the rare ability to communicate with and command the Sea Kings, massive creatures capable of sinking entire islands. This power is not just a tool for destruction but is intended to guide the ship Noah for a specific purpose in the future. Shirahoshi’s role as an Ancient Weapon makes her one of the most strategically significant characters in the final saga of the series.
Noah
The Noah, known as the "Ship of Promise," is a colossal vessel roughly half the size of Fish-Man Island itself. It was constructed during the Void Century and has sat in the Sea Forest ever since, awaiting its designated day of use. The ship was designed to be pulled by Sea Kings, a feat only possible through the powers of Poseidon Shirahoshi. While the exact details of its mission remain a mystery, it is widely believed that Noah will serve as the ark to transport the entire Fish-Man race to the surface world when the time comes to finally end their isolation.
Destruction Prophecy
Adding a layer of tension to the island's future is the prophecy made by Madam Shyarly, a fortune teller known for her unerring accuracy. She predicted that Monkey D. Luffy would be the one to bring about the destruction of Fish-Man Island. While the Straw Hats left the island in peace, the prophecy remains unfulfilled, casting a shadow over the "final war" to come. Many fans speculate that the destruction of the island will be a necessary step in destroying the Red Line and Mary Geoise, ultimately creating the "All Blue" and allowing the Fish-Men to live freely under the true sun on the surface.
