If you are looking for countries that start with J, there are exactly three sovereign United Nations member states whose standard English names begin with the letter J:
- Jamaica
- Japan
- Jordan
These three countries are remarkably different. Jamaica is a Caribbean island nation, Japan is an East Asian archipelago, and Jordan is a country in Western Asia.
The current United Nations Member States directory confirms Jamaica, Japan, and Jordan as the three countries listed under J.
Quick Answer: There are three countries that start with J: Jamaica, Japan, and Jordan.
How Many Countries Start With J?
There are 3 countries beginning with J when using the standard English names of current sovereign UN member states.
| # | Country | Capital | UN Region | ISO Codes |
|---|---|---|---|---|
| 1 | Jamaica | Kingston | Caribbean | JM / JAM |
| 2 | Japan | Tokyo | Eastern Asia | JP / JPN |
| 3 | Jordan | Amman | Western Asia | JO / JOR |
The United Nations geographical names database classifies Jamaica in the Caribbean, Japan in Eastern Asia, and Jordan in Western Asia.
So whether you are completing a geography quiz, solving an alphabetical puzzle, or studying world countries, the full J list is simple:
Jamaica, Japan, and Jordan.
Countries That Start With J by Region
The three J countries are spread across two broad geographic areas.
| Geographic Area | Number | Countries |
|---|---|---|
| Americas / Caribbean | 1 | Jamaica |
| Asia | 2 | Japan, Jordan |
| Africa | 0 | None |
| Europe | 0 | None |
| Oceania | 0 | None |
Japan and Jordan are both in Asia, but they lie in very different parts of the continent.
Japan is in Eastern Asia, while Jordan is in Western Asia.
Jamaica lies in the Caribbean region of the Americas.
How Does J Compare With Other Rare Country Letters?
Three countries make J a relatively uncommon starting letter, but it is not the rarest.
For example, Oman stands alone under the letter O, while Qatar is similarly the only sovereign country represented by Q.
Some letters are even more unusual. The W list contains no sovereign UN member state at all.
Other letters produce much longer or more complicated lists. There are eight current countries grouped under E, while official naming conventions make the D list surprisingly complicated.
J sits somewhere in the middle:
not empty, not unique, but limited to just three countries.
1. Jamaica
Jamaica is an island country in the Caribbean Sea.
Its capital and largest city is Kingston, while its ISO country codes are JM and JAM.

Where Is Jamaica?
Jamaica is located in the Caribbean Sea, south of Cuba and west of Hispaniola.
It is part of the Greater Antilles island group.
Although Jamaica is often associated primarily with tropical beaches, much of the island’s interior is mountainous.
Its landscapes include:
- tropical coastlines
- limestone hills
- forests
- waterfalls
- river valleys
- agricultural land
- the Blue Mountains
Where Does the Name Jamaica Come From?
The name Jamaica developed from an Indigenous Taíno name.
Jamaica’s official tourism authority explains that the Taíno people called the island Xaymaca, commonly interpreted as “land of wood and water.”
The official history of Jamaica explains that Taíno communities lived on the island before Europeans arrived.
A Short History of Jamaica
The Taíno were living on Jamaica when Christopher Columbus reached the island in 1494 during his second voyage to the Americas.
Spanish colonization followed.
Disease, forced labor, and displacement devastated the Indigenous population during the colonial period.
England seized Jamaica from Spain in 1655, after which the island became an important British Caribbean colony.
Sugar plantations became central to the colonial economy and relied heavily on the forced labor of enslaved Africans.
The descendants of those Africans profoundly shaped Jamaica’s culture, language, music, religion, food, and national identity.
The Maroons of Jamaica
One especially important part of Jamaica’s history involves the Maroons.
Communities of formerly enslaved Africans established settlements in Jamaica’s mountainous interior and resisted British colonial authority.
After prolonged conflict, British authorities signed treaties with Maroon communities during the 18th century.
Their history remains an important part of Jamaican heritage.
When Did Jamaica Become Independent?
Jamaica became independent from Britain on August 6, 1962.
The Jamaica Information Service records that Jamaica formally became an independent nation on that date.
Jamaica joined the United Nations on September 18, 1962.
Jamaica’s UNESCO World Heritage Sites

Blue and John Crow Mountains

The site combines important natural biodiversity with cultural heritage connected to Jamaican Maroon communities.
Port Royal
Port Royal was one of the Caribbean’s major 17th-century trading settlements.
Part of the historic town was devastated by the 1692 earthquake, which caused sections of the settlement to sink beneath the sea.
Its archaeological remains preserve an unusual record of Caribbean colonial history.

A Short History of Japan
Japan has a long history extending from prehistoric communities to one of the world’s largest modern economies.
Early archaeological periods include the Jomon and Yayoi cultures.
Over time, increasingly centralized political institutions emerged.
The early capitals of Asuka and Fujiwara were especially important in the development of centralized government.
Samurai and the Shogunates
From the late 12th century onward, warrior governments played a major role in Japanese politics.
Different shogunates exercised political power while the imperial institution continued.
The Tokugawa shogunate, established in the early 17th century, presided over a long period of internal stability.
The Meiji Restoration
A major transformation began in 1868 with the Meiji Restoration.
Political power was reorganized around the emperor, and Japan underwent rapid modernization.
During the following decades, the country built modern institutions, industries, transportation networks, armed forces, and education systems.
Japan After World War II
