One Piece comes to life as a brilliant mixture of contemporary fantasy and reality, where the imaginative islands are quite frequently based on real-life geography and culture. The author of the series, Eiichiro Oda, is famous for drawing some details of real history, architecture, and landscapes into his fictional settings. Eiichiro succeeds not only in depth in the anime, but also in bringing familiarity in the exploration of fantasy worlds to the fans. One Piece has numerous islands that are culturally and geographically varied, but at the same time memorable and impressive because they are the places of some most iconic adventures.
It is worth stating before getting into the list that these islands are popular not only due to the arcs they host but also due to the layered connections to real-life locations that they establish. This is because Oda has managed to incorporate the use of real-life cultural concepts into the plot that ensures the islands have sound implications both in the storytelling and aesthetically. The entries on this list are the most popular islands of One Piece and the real-life places they potentially got their inspiration from.
10. Thriller Bark – Inspired by Gothic Europe

Thriller Bark is one of the most interesting islands in One Piece, being a haunted island in the shape of a giant ship. Its dark, foreboding castles, graveyards, and shadows are memorable. The architecture of the island is highly influenced by haunted manors and graveyards of Gothic Europe, especially Transylvania.

9. Fish-Man Island – Inspired by Atlantis and Southeast Asian Coral Reefs

The island of Fish-Man is very important in One Piece; it is the place that leads to the New World. Its beauty under the water surface, with the coral structures and the bubble-like forms, creates the image of coral reefs in Southeast Asia, along with the mythical Atlantis. The popularity of the island is explained by focusing on and highlighting the concepts of discrimination, unity, and hopes for a good future. It is also extremely attractive in terms of architecture and coloring, which makes it one of the most visually appealing islands.
8. Drum Island – Inspired by Alaska and Northern Europe

The snowy ground on which the Straw Hats encounter Chopper, the doctor of the crew, is called Drum Island. The snow-covered mountains and frozen landscapes would bring memories of Alaska or Scandinavia. It gained popularity because of its sentimental plot, especially the speech of Dr. Hiriluk about the blossoming of cherry trees that came out of the snow. The tough conditions of the winter on the island are also a reminder of the strength of the people who visit it along the journey in One Piece, making the island a memorable visit.
7. Skypiea – Inspired by South American Mythology and Machu Picchu

One Piece has one of the most fantastical islands, Skypiea, a land among the clouds that could be reached only via the Knock-Up Stream. It has a similar architecture and cultural influence to those of the South American cultures, especially the Inca Empire and the ruins of Machu Picchu. What makes it so popular is the elements of mythology, the history of the Shandian people, as well as the theme of faith and heritage, which are present in the arc. Its breezy location furnishes one of the most imaginative backgrounds in the series.
6. Enies Lobby – Inspired by Venice, Italy

The Judicial Island, also known as Enies Lobby, is an island enclosed by waterfalls that expand into the sea, similar to Venice but in a much more exaggerated manner. Its building design, based on European style, makes it one of the most aesthetically stunning places in One Piece. The island has gained popularity not only due to design, but to one of the most dramatic arcs of the series, with the Straw Hats declaring war on the World Government to save Robin.
5. Wano Country – Inspired by Feudal Japan

Wano Country is perhaps one of the most popular islands in One Piece that is directly based on feudal-era Japan. Its architecture, clothing, and traditions also reflect the Japanese culture, with cherry blossom, samurai, and the shogunate as some of the defining elements of the land. Wano is especially popular due to being the stage where one of the most crucial arcs of the story takes place, which is packed with battles and alliances, as well as more in-depth world-building. It is popular because of the detail and depth of its cultural elements, beautiful surroundings, and the way that it seamlessly fits into the rest of the history of the world.
4. Water 7 – Inspired by Venice and Genoa

One of the most popular islands in One Piece is Water 7, which resembles Venice, including canals, gondolas, and Roman-style paving stone architecture. The busyness of the trade and the shipbuilding industry of the city points to the real-life Genoa, an ancient sea city. The popularity of Water 7 is explained by the creative use of colors and the way it is used to showcase the Galley-La Company and Franky. It also preconditions the critical arc of Enies Lobby, and because of this aspect, it is a favorite of many fans who admire it both aesthetically and in terms of the significance of its story.
3. Whole Cake Island – Inspired by Candy-Themed Fairy Tales and French Patisseries

Whole Cake Island is a fantasy-like island full of candies, chocolates, and sweets that certainly possesses elements of fairytales, such as Hansel and Gretel, as well as French pastry culture. It has bright and fanciful designs, which set it apart visually compared to most other One Piece islands. Whole Cake Island is famous not only because of its bright environment but also for the tension and dramatic struggle of the Big Mom arc, where tension, politics, and family relations are intertwined into a fantastic world.
2. Marineford – Inspired by Real-World Naval Bases

Marineford is the headquarters of the Marines and one of the most famous spots in One Piece. Though it is not an island as such, it is a battleground and a strategic point of central location. Its architecture replicates that of military bases and naval fortresses in reality, with massive buildings that underline the rule of authority and discipline. The popularity behind Marineford lies in the fact that this place is the setting of the Paramount War arc, one of the most emotional and action-packed arcs in the series, and shocking events help shape the meaning of the entire story.
1. Alabasta – Inspired by Ancient Egypt

Alabasta comes out on top for being extremely popular and having a real-world influence. Modelled after Egypt, with its deserts, pyramids, and ancient remnants, Alabasta is a centre of political machinations, rebellion, and hope. It's a popular arc about Crocodile, Princess Vivi, and trying to save a kingdom from itself in a civil war. The Egyptian-influenced artwork, from desert cities to the royal palace, lends it a timeless appeal that really speaks to fans.
The Influence of Real-World Lands on One Piece’s Most Popular Islands
The One Piece islands are not mere examples of place setting; they are characters in themselves, with the elements of their fantastical nature based on well-grounded inspirations in the real world. Varying between the deserts of Alabasta that look like ancient Egypt to the canals of Water 7 that resemble Venice, these worlds show just how brilliant Eiichiro Oda can be when simultaneously blending fiction with reality.
