Introduction
The official name of Japan in Japanese is Nihon-koku (日本国) or Nippon-koku (日本国). Both pronunciations are officially accepted and refer to the same country.
In English, the country’s official name is simply Japan.
The characters 日本 mean “origin of the sun” or “where the sun rises,” while 国 means “country” or “state.” Together, the official Japanese name can be translated as “State of Japan” or “Country of Japan.” This meaning is the reason Japan is widely known as the Land of the Rising Sun.
Japan’s Official Name in Japanese
Japan’s constitutional name is written as:
日本国
This name has two accepted pronunciations:
- Nihon-koku
- Nippon-koku
Both pronunciations are correct and officially recognized. There is no law declaring one pronunciation more official than the other.
What Is Japan’s Official Name in English?
Although the Japanese constitutional name is Nihon-koku or Nippon-koku, the country’s official English name is simply:
Japan
This is the name used in:
- International treaties
- Diplomatic relations
- The United Nations
- International sporting events
- English-language government communications
- Passports and travel documents
The literal English translation of 日本国 is often written as State of Japan, but the internationally recognized official English name remains Japan.
Why Does Japan Have Two Official Pronunciations?
The Japanese language allows multiple accepted readings for many kanji characters.
For 日本:
- Nihon is the pronunciation most commonly used in everyday conversation.
- Nippon is often used during formal ceremonies, sporting events, and patriotic occasions.
Both are equally valid and officially accepted throughout Japan.
Meaning of Japan’s Official Name
The name 日本 consists of two kanji characters:
- 日 = Sun
- 本 = Origin or Source
Together they mean:
- Origin of the Sun
- Source of the Sun
Since Japan lies east of mainland China, it appeared to be the place where the sun rose each morning. This geographical perspective inspired the country’s name.
Because of this meaning, Japan has long been known as the Land of the Rising Sun.
How Did the Name “Japan” Originate?
Many people wonder why English speakers say “Japan” instead of “Nihon.”
The English name evolved over centuries through trade and cultural exchange.
The general development was:
- Chinese pronunciation of 日本
- Adoption by Southeast Asian traders
- Portuguese spelling “Japão”
- Dutch adaptation
- English spelling “Japan”
By the early modern period, “Japan” had become the standard English name used worldwide.
Historical Background
Japan has not always been known as 日本.
Earlier historical names included:
- Wa (倭)
- Yamato
During the 7th century, Japanese rulers officially adopted 日本 as the country’s name to reflect its identity and diplomatic status.
Over time, this became the official name recognized throughout East Asia.
Japan’s Official Name Under the Constitution
Japan’s Constitution refers to the country as 日本国.
The Constitution does not specify whether the name must be pronounced “Nihon-koku” or “Nippon-koku.”
As a result, both pronunciations continue to be officially accepted today.

This pronunciation is commonly associated with:

“Nippon” conveys a strong sense of national pride and tradition.
Common Misunderstandings
Several misconceptions exist regarding Japan’s official name.
Some people believe that only “Nippon” is correct, while others think only “Nihon” is official. In reality, both pronunciations are officially accepted.
Another misconception is that Japan recently changed its official name. No such change has occurred.
Some also assume that “State of Japan” is the country’s official English name. While it is a correct literal translation of 日本国, the internationally recognized official English name is simply Japan.

“Islamic Republic of Japan” surged online
The keyword “Islamic Republic of Japan” surged online after U.S. President Donald Trump used the phrase during remarks at the NATO summit on July 8, 2026. The comment quickly went viral because Japan is not an Islamic republic, and many observers interpreted it as an apparent verbal mix-up in which Trump intended to refer to the Islamic Republic of Iran. Clips of the remark spread rapidly across social media and news outlets, fueling widespread discussion, memes, and online searches
Final Thoughts
The answer to What Is Japan’s Official Name depends on the language being used. In Japanese, the country’s official constitutional name is Nihon-koku (日本国) or Nippon-koku (日本国), with both pronunciations officially accepted. In English, the country’s official name is simply Japan.
The meaning of the name, “origin of the sun,” has shaped Japan’s identity for centuries and explains why it is famously known as the Land of the Rising Sun. Whether referred to as Japan, Nihon, or Nippon, all three names represent the same nation with a remarkable history and global influence.
