One Piece World Map Navigation Explained!

The One Piece World is full of mysteries and adventure.

The Red Line and the Grand Line divide the One Piece world into 4 seas, the 4 Blues: East Blue, West Blue, North Blue and South Blue.

As a large-scale action series, One Piece’s world map can sometimes make it hard for fans to understand what’s going on.

There are maps of the One Piece planet available, but they are hard to understand and usually don’t give any more information.

Once the whole thing is clear, though, the One Piece world map is easy to understand and read, especially for people who have watched past the Reverse Mountain story.

It’s important for One Piece fans to use Reverse Mountain as a point of reference for geography because it gives them a place to start when looking at the world map.

Here is a full explanation of One Piece’s world map.

Exploring the One Piece’s World Map

As a whole, the One Piece world map might seem like a lot to take in. That’s why it’s important to take your time and look at it in pieces.

The picture above is a good reflection of the series’ world map as a whole, though the sizes and locations of the islands may not be exact. It shows a lot about the world’s geography and will help us find our way.

On the map, there are four squares. The top right sea is called the East Blue. This is where Luffy meets Zoro, Nami, Sanji, and Usopp, and the four start their trip.

The blue sea in the top left is called the North Blue, the blue sea in the bottom left is called the West Blue, and the blue sea in the bottom right is called the South Blue. The Grand Line and the Red Line split the world into these four seas.

The Red Line is the name for the middle continent on the map. It is the main region of the series. It goes all the way around the world like a belt and helps separate the four blues.

In the middle of this part of the Red Line is the Reverse Mountain. This is how ships from any of the four blues can get to the Grand Line.

The Grand Line is the belt that runs horizontally across the map and looks like an equator. It meets the Red Line at Reverse Mountain.

From either of the four seas, the only way to get to the Grand Line is down the path from the top of Reverse Mountain.

This is because of the Calm Belts, which are two places like the equator that sit above and below the Grand Line. There isn’t much wind in the Calm Belts, so it’s hard to sail ships there.

Also, they are full of monsters called Sea Kings, which means that any floating ship that isn’t moving will be attacked here at some point.

The Calm Belts cover the whole Grand Line, so the only way to get to the exploring equator of the world is through Reverse Mountain. The movie above shows the Red Line and the other side of the world.

Once the first half of the Grand Line is over, ships have to go under the Red Line and around Fishman Island to get to the second half of the Grand Line.

The first half is called Paradise, and the second half is called the New World. Since they left Fishman Island, Luffy and the Straw Hats have been traveling to the New World.

The New World goes all the way back to the area around Reverse Mountain on the Red Line, where ships can leave the Grand Line by some means that are not known.

Fans will definitely see the Straw Hat Pirates try this at some point, but until they do, any information about how to leave the New World is just a guess.

The Red Line

Red Line goes all the way around the world, from the north to the south. In the One Piece world, it is the only continent. It also splits the two big seas into four smaller ones.

On the Red Line, where the Grand Line meets the New World, you can find the famous Holy Land of Mary Geoise.

The Red Line is also used to divide the New World from the rest of the world. When the first part of the Grand Line ends, sailors must go under the Red Line and over Fishman Island to get to the New World.

Reverse Mountain

One of the few entrances to the Grand Line, the Reverse Mountain is one of the narrow creeks of the Red Line.

Waters from all the different blues collectively climbs up to empty into the Grand Line.

Marie Joise or Mary Geoise

Marie Joise

This city houses the Pangaea Castle where the World Government meets and functions and houses the 5 Gorosei and the seat of the ruler of the World and is known as the Domain of Gods which is home to the Celestial Dragons and their slaves.

The Grand Line

The Grand Line

The Grand Line goes around the world, or, in One Piece words, it goes around the whole world. This road is used by almost every pirate.

The grand line is also where most of the story takes place. The One Piece treasure is the main reason why so many pirates journey along the Grand Line.

One Piece is thought to be on Laugh Tale Island, the last island in the Grand Line. The Grand Line is split in half by the Red Line.

They are called Paradise, which is a very dangerous and uncertain place. The other part, where Wano country is, is called the New World. The New World is run by the four rulers of the sea.



The first half of the Grand Line is the sea that is riddled with different kinds of islands.

It is home to islands like Cactus Island, Little Garden, Holliday Island, Drum Island, Alabasta, Jaya, Florian Triangle, Sabaod Archipelago, Momoiro Island, Boin Island, Kuraigana Island, Boyn Island and so many more that remain unexplored.

This half is supposed to be “a paradise” as compared to the New World which starts on the second half of the Grand Line.

This patch starts at the Reverse Mountain and ends at Sabaody Archipelago.

The log pose used to navigate here has only one needle.

New World

New World

The New World of the Grand Line is the second half of it. It is crazy and common sense doesn’t work here at all.

One also has to use a log pose that has three needles since an Island existing and suddenly disappearing due to some reason often happens in this part.

It is the true challenge of the Grand Line and is the place one needs to conquer and navigate to become the Pirate King.

This patch starts with the Sabaody Archipelago and end as Lodestar Island which is the last island of the Grand Line, after which comes Reverse Mountain again.

Calm Belt

Calm Belt

The reason why the Grand Line is so isolated and can’t be entered from anywhere other than Reverse Mountain is due to the existence of the Calm Belts.

These water straits surprisingly never have any wind or waves and any ship that goes into the Calm Belt can often never get out.

These belts serve as breeding grounds for the biggest species of Sea Kings that devour any ship that dare to bother them.

The Calm Belts do have Islands like the Maiden Island Amazon Lily, Ruskaina Island and is the most famous housing the Great Prison Ipel Down.

The 4 Blues

The 4 Blues

The One Piece world has the four seas which is where most people reside.

The East Blue is considered as the weakest Blue due to the lack of a strong nation ruling it and it instead being independent islands like Conomi Island having places like Arlong Park, Cooyashi Village and Gosa Village, Dawn Island having the Goa Kingdom and Yotsuba Islands having Shell Town.

The West Blue is one of the most chaotic places there is.

The now non-existent land of Ohara was located here along with notable places like Thriller Bark that later floated into the Florian Triangle, Illusia Kingdom ruled by Thalassa Lucas who was shown attending the Reverie.

The North Blue’s most significant contribution to the series is the Germa Kingdom.

They are known throughout the world for their advanced scientific technologies and research.

The Rubeck Island along with the neighboring Minion and Swallow Islands were involved in a trade deal regarding the Ope Ope No Mi which is now used by Trafalgar Law.

The most significant contribution that the South Blue has made to the series is the Torino Kingdom or Bird Kingdom.

This Kingdom housed Chopper throughout the timeskip and also helped advance his medical knowledge significantly. It also houses the Baterilla Island where Ace was born.

The Sky Ocean

The Sky Ocean

This is the sea in the ocean, which is made out of clouds. It is also known as the White-White Sea.

This sea has Islands floating in it made out of “Island Clouds” or “Shima-gumo” which is made when Pyrobloin, a compound of Kairoseki or Sea Prism Stone interacts with the clouds.

The Moon

The One Piece world is speculated to have 6 moons, but we have confirmed information regarding only 1 which Enel refers to as “Fairy Vearth” or “Endless Earth”.

The name indicated that this moon likely has no water body at all. Enel did befriend aliens on this moon who were shown to have wings like the Skypieans.

In Summation

At first glance, the One Piece world map looks difficult, but it’s not so scary once you know how it works.

Still, many fans don’t understand how the North, East, South, and West blues got their names or how to get on the Grand Line.

There aren’t many, if any, government maps that show the world on a 1:1 scale in terms of island size and location, but there are a lot of maps that show how the world is set up in general.

They are important for any fan of One Piece to understand where things are in the world.
