海兵隊 in Chinese / Japanese...

海兵隊 is the Japanese and Korean way to express “Marine Corps” or simply “Marines.” It is not specific, so this can be the Marine Corps of any country, such as the British Royal Marines to the U.S. Marines.

Breaking down each character, this means:
“ocean/sea soldiers/army corps/regiment/group.”

米海兵隊 is the Japanese way to write “United States Marine Corps” or simply “U.S. Marines.”

Breaking down each Kanji, this means:
“rice (American) ocean/sea soldiers/army/military corps/regiment/group.”

This title will only make sense in Japanese, it is not the same in Chinese! Make sure you know your audience before ordering a custom wall scroll.

If you are wondering about rice, America is known as “rice country” or “rice kingdom” when literally translated. The Kanji for rice is often used as an abbreviation in front of words (like a sub-adjective) to make something “American.” Americans say “rice burner” for a Japanese car and “rice rocket” for a Japanese motorcycle. If you did the same in Japanese, it would have the opposite meaning.

Note: I have not verified this but I’ve found this title used for U.S. Marines in Korean articles, so it’s most likely a normal Korean term as well (but only in Korean Hanja).
