Information About the Geography

Let us start by discussing the information we have about the planet and how it is divided. The exact name of the planet remains unknown. What we do know is that the world consists of significantly more water than land. The inhabitants live on separate islands scattered throughout the vast seas, with most of these islands under the control of the World Government, led by the Five Elders (Gorosei), who are secretly ruled by Imu.

Unlike Earth, this world lacks a unified magnetic field. Each island has its own magnetic properties, making it impossible to navigate using a normal compass. Instead, sailors rely on a specialized device called aLog Pose. To date, no one possesses a complete map of the planet, though Nami, the navigator of theStraw Hat Pirates, dreams of creating one.

According to Dr. Vegapunk’s recent broadcast, the planet once had more landmass. However, events that occurred during the Void Century caused significant changes, ultimately leading to a world now dominated by water. Moreover, Vegapunk has even predicted that, in time, the entire planet may eventually be submerged.

The people of this world refer to it simply as “the World” (Japanese: Sekai). However, the inhabitants of Skypiea have a unique term for it, calling it Vearth.

Geography ofOne Piece

Two massive formations, the Red Line (Reddo Rain) and the Grand Line (Gurando Rain), primarily divide the world ofOne Piece. People refer to the vast ocean as the Blue Sea (Burū Shī).

The Red Line (Reddo Rain) is a massive, continuous landmass that encircles the globe. It is the only known “continent” and acts as a natural divider, splitting the world into two halves. The Red Line plays a crucial role in world geography, separating the Grand Line into two sections: Paradise (the first half) and the New World (the second half).

The Grand Line (Gurando Rain) is a treacherous sea that runs perpendicular to the Red Line, effectively dividing the world into four distinct oceans. This region is notorious for its unpredictable climate, erratic currents, and dangerous wildlife. It is also home to the most powerful pirate crews and the location of the legendary One Piece treasure.

Two Calm Belts flank the Grand Line to the north and south. These regions are devoid of wind and ocean currents, making them nearly impossible to traverse. They are also home to gigantic Sea Kings, making the journey extremely perilous.

Together, the Red Line and Grand Line serve as the longitude and latitude of this world, dividing the Blue Sea into four major oceans:

There is also a rumored location called All Blue, where fish from all four seas coexist. Its existence remains unconfirmed, but it is the dream of Sanji, the Straw Hat Pirates’ cook, to find this legendary place.

The world is said to have around 20,000,000 islands, most of which support civilizations and diverse forms of life. Like Earth,One Piece’sworld has North and South Poles, which are reportedly cold and inhabited.

Climate of Islands inOne Piece

The planet features a wide variety of climates, with many islands exhibiting fixed weather conditions that never change. Each island’s climate is largely influenced by the surrounding sea.

For example, islands located in Winter Islands remain covered in snow year-round. Meanwhile, islands within warmer regions maintain tropical conditions. However, in the open sea, the weather is highly unpredictable, and calm conditions can rapidly turn into violent storms.

Upon entering the New World, these erratic weather patterns become even more extreme. Some islands have magnetic fields that fluctuate, rendering a single Log Pose useless. This makes navigation in the New World incredibly difficult unless travelers have prior knowledge of the region’s conditions.
