- 中華人民共和国 (ちゅうかじんみんきょうわこく): People's Republic of China
Usage Notes
This suffix is formal and often used in official or written contexts, such as in government documents, formal speeches, or news reports. In everyday conversation, the suffix is often omitted, and the country name alone is used (e.g., 日本 instead of 日本国).
Common Mistakes
Learners sometimes overuse ～国 in casual speech, which can sound overly formal or unnatural. Also, some country names do not commonly use this suffix in daily conversation, so it's important to learn which names typically include it.
