米国（べいこく、beikoku）
- United States

The word 米国, pronounced べいこく (beikoku), is the Japanese term for the "United States of America" or simply "USA". It is a shortened, more formal, and commonly used way to refer to the country. The characters are derived from Chinese and have specific meanings that combine to represent the concept.

⚫︎米国の文化に興味があります。 Translation: I am interested in American culture. ⚫︎ 私は来年、米国へ旅行する予定です。 Translation: I plan to travel to the United States next year. ⚫︎ 米国の大統領は、本日、記者会見を開きました。 Translation: The president of the United States held a press conference today.

⚫︎ 米国 is used in formal and informal contexts. ⚫︎ It's very common in everyday conversation, news reports, and written documents. ⚫︎ It is often used instead of the longer, more formal term "United States of America" (アメリカ合衆国 - Amerika Gasshūkoku). ⚫︎ While understandable, using the full term in casual conversation could sound a bit overly formal.

⚫︎ The word is typically written with the kanji 米国. ⚫︎ The reading is べいこく in hiragana. ⚫︎ There are no variations in the okurigana. ⚫︎ Occasionally, in very informal contexts, you might see it written in katakana as ベ イ コ ク (beikoku), but this is less common.

⚫︎ アメリカ (Amerika) - "America" (a more common and casual term) ⚫︎ アメリカ合衆国 (Amerika Gasshūkoku) - "United States of America" (the full formal term) ⚫︎合衆国 (Gasshūkoku) - "United States" (a more formal and shorter term, but can refer to other countries like Mexico)

⚫︎ There aren't direct antonyms, as 米国 refers to a specific place. However, you could consider words referring to other countries as being in opposition.

The kanji for 米 (bei) literally means "rice" or, by extension, the United States. This came from the use of "米" to represent the "米州" (beishū), "the American continent." 国 (koku) simply means "country" or "nation." Therefore, 米国 literally translates to "rice country" or "country of rice." Although the literal translation may seem unusual, it's a well-established and accepted term. The selection of the kanji 米 for "United States" is a result of a historical transliteration choice, and its original meaning (rice) is no longer relevant in the modern use of the word.
