What is a suffix for Japan or Vietnam?

When discussing names and places in Asia, it’s important to understand suffixes – the letters or syllables added to the end of a word to modify its meaning. Two countries with notable suffixes in their names are Japan and Vietnam. Understanding the meanings behind these suffixes provides cultural context and insights into the history and identities of these nations.

The Suffix -an in Vietnam

Vietnam’s official name in English is the “Socialist Republic of Vietnam.” The suffix “-an” at the end of Vietnam indicates something belonging to or associated with Vietnam. This follows conventions in English for denoting countries and nationalities, such as American, Canadian, Chilean, and so on.

The suffix “-an” comes from the Western naming convention for countries in Southeast Asia during colonial times. Westerners added the suffix to names like Burma, Siam, and Tongking to create the modern country names of Burma, Thailand, and Vietnam. The local Vietnamese name for their country is “Việt Nam.” This name does not have any direct suffix, but the “-an” was added to create “Vietnam” for English speakers.

The Suffix -koku in Nihon-koku for Japan

Japan’s official name in Japanese is “Nihon-koku” (日本国). This name features the suffix “-koku” (国), which means “country” or “nation state.” This suffix appears in other Japanese country names like Chūgoku (中国) for China and Igirisu-koku (イギリス国) for the United Kingdom.

The rest of Japan’s name is “Nihon”, which is a shortened way to say “Nippon” (日本). This comes from the Chinese reading of the characters 日本, which mean “origin of the sun.” Together, Nihon-koku conveys the idea of “the nation of Japan.” The suffix -koku identifies Japan as a sovereign country.

Other Notable Suffixes in Asia

Suffixes are found in many Asian language names and places, providing insight into meanings and identities:

  • -stan – Means “country” or “place of” in Persian. Ex: Pakistan, Afghanistan, Tajikistan.
  • -pur – From Sanskrit for “city.” Ex: Singapore, Jaipur, Lucknow.
  • -zhou – Chinese for “prefecture” or “state.” Ex: Guangzhou, Fuzhou, Hangzhou.
  • -do – Korean suffix meaning “province.” Ex: Jeollado, Gyeongsangbuk-do.

The Importance of Names and Suffixes in Culture

Names are an important part of culture and identity for countries. Suffixes like -koku and -an reflect historical naming conventions and perspectives in different languages. While Vietnam uses the Western suffix, Japan’s name in Japanese retains the suffix -koku to signify a sovereign nation.

Within regions, suffixes help distinguish between similar place names and types of places. Learning the meanings behind suffixes can provide cultural insight. For instance, recognizing that -stan means country signals a place’s regional identity and history in Central and South Asia. Suffixes tell a subtle part of the stories behind names and cultures.


Suffixes play an important role in Asian place names and identities. The suffixes -an in Vietnam and -koku in Japan demonstrate two different language conventions for signifying countries. Beyond just naming places, suffixes like -pur, -zhou, and -do give additional cultural context and meaning in South, East and Central Asia.

Paying attention to suffixes within names provides insights into histories, cultures, languages and perspectives. Rather than just labels, suffixes tell part of the rich stories behind places and cultures across Asia.
