AsOne Pieceenters the final saga, it won’t be long before the various secrets are unraveled. Like Wano, there are many old places that hold a lot of mysteries. While the crew has already sailed to some of the oldest kingdoms in the series, there are some places that remain unexplored. However, that will change once the Straw Hats sail to these kingdoms; the fans will be able to experience the kingdom’s unique secrets.

8Wano Country

The Wano Country is one of the oldest kingdoms in the series, and its current ruler is Kozuki Momonosuke. There are two Wano countries; one is the present-day Wano, which is situated on the side of the mountain, and the second one is situated at the bottom and is currently drowned underwater.

The country closed its borders a long time ago, which resulted in it becoming completely cut off from the rest of the world. The people in Wano were unaware of the events that were taking place in the outside world, and the outside world didn’t know about the internal affairs of Wano. The country of Wano has a lot of significance historically. It is home to some of the most talented craftsmen and swordsmiths. The Kozuki clan is known for creating the poneglyphs, which are extremely important to the story.

7The Great Kingdom

The Great Kingdom existed before the Void Century, making it one of the oldest known kingdoms. It is believed to have been so wealthy and powerful that other kingdoms became jealous. According to Clover, the twenty founding members of the World Government were its enemies, and they formed an alliance to destroy it.

Unfortunately, the alliance of the twenty countries managed to eradicate the Great Kingdom. After their successful mission, the World Government erased all traces of the kingdom’s existence, with the poneglyphs remaining as the only known source as they are indestructible. To counter this problem, the World Government forbade anyone from deciphering the Poneglyph, and anyone who broke this rule was harshly dealt with.

6Alabasta

The kingdom of Alabasta is one of the twenty foundingcountries of the World Government. In the past, they corroborated with the other countries to take down the Great Kingdom. The last known ruler of the country was Nerfertari Cobra, who, according to the news, was killed by Sabo.

In Cobra’s absence, Vivi was supposed to take over the affairs of the kingdom, but she has been missing since the Levely. The kingdom has the poneglyph, which has the location of Pluton inscribed on it. So, it is clearly a crucial element of the story, and the kingdom might play a role in the great war.

5Fish-Man Island

Fish-Man Island was the first place that the Straw Hats visited before they entered the New World. The island serves as a gateway to the New World for pirates and other people who are not permitted to cross. For this reason, Fish-Man Island has been visited by some of the most legendary figures in the world ofOne Piece.

In the past, the island was visited by Joy Boy, who made a promise to the residents; however, he could not keep his promise. The island has various races living together, and since humans hate them, these races stay below the surface. The Fish-Man island is important to the story, and the Straw Hats will definitely revisit the place.

4Jaya

Jaya is often overlooked in terms of importance, but it is the place where one of the best friendships in the story was formed between Kalgara and Mont Blanc Noland around 400 years ago. At that time, the island hadn’t lost the Upper Yard due to the Knock Up stream, so it was much bigger.

Jaya was home to the Shandians after they moved from the Moon. In addition to the riches, the island also boasted an incredible variety of flora and fauna. Currently, the island is known to be a lawless place, and it is frequently visited by pirates.

3Ohara

The island of Ohara was located in the West Blue, and it served as the birthplace of Nico Robin, the archeologist of the Straw Hats. The island came into existence 5000 years ago. It became famous for the Tree of Knowledge, which was just as old as Ohara itself.

Over the years, it attracted many scholars and archeologists. These scholars eventually started deciphering the poneglyphs, and once the World Government found out, they ordered a Buster Call. The Buster Call resulted in the demolition of the entire country, with Nico Robin being the only survivor.

2Elbaf

Elbaf is a country in the New World, andit is the home of giants. The giants are much bigger and more powerful than any other race. It is considered to be the most powerful country because of its immensely strong army.

The giants are also known to live for hundreds of years, so it is quite obvious that Elbaf has existed for a long time. It is very likely that the Straw Hats will visit Elbaf before they make their way to Laugh Tale.

1Mokomo Dukedom

The Mokomo Dukedom exists on the back of Zunesha. It was created almost a thousand years ago by the Mink tribe. Previously, the Mokomo Dukedom was ruled over by two rulers - Inuarashi and Nekomamushi. However, after the events of the Wano Country arc, the two Minks named Carrot the new ruler of the Mokomo Dukedom as she inherited the will of Pedro, and they believed that she could lead the country into a new era.
