Then paragraph: "The joint operation began early in the Asian session, with the Bank of Japan and the US Treasury buying yen in an effort to stem the currency's slide. Bitcoin, which had been trading in a narrow range, quickly reversed course, shedding more than 2% within a few hours. The decline was broad-based, with other major cryptocurrencies also losing ground."
Translation: "공동 개입은 아시아 장 초반에 시작됐으며, 일본은행과 미국 재무부가 엔화 하락을 막기 위해 엔화를 매수했다. 좁은 범위에서 거래되던 비트코인은 빠르게 방향을 바꿔 몇 시간 만에 2% 이상 하락했다. 하락은 광범위하게 나타나 다른 주요 암호화폐도 하락했다."
We keep "Bank of Japan" as "일본은행"? Actually it's a proper noun, but we can translate as "일본은행" because it's the official Korean name. But the instruction says keep proper nouns in original form. However, "Bank of Japan" is an institution, we might keep as "Bank of Japan" or translate. I think it's common to translate to "일본은행". Similarly "US Treasury" -> "미국 재무부". But the instruction says "Keep proper nouns (names, company names) in original form." So "Bank of Japan" is a name, but it's also a company? It's a central bank. To be safe, I'll keep "Bank of Japan" and "US Treasury" as is? But that might sound unnatural. The instruction says "Keep proper nouns (names, company names) in original form." It doesn't say we must keep them, it says we should keep them. So we can translate if it's common? Actually it says "Keep proper nouns (names, company names) in original form." That means we should not translate them. So we should write "Bank of Japan" and "US Treasury" in English? But in Korean text, it's common to use Korean translations. However, to strictly follow, we should keep them as is. But the instruction also says "Use appropriate Korean terminology for crypto/tech terms" - that's for tech terms, not for proper nouns. So I'll keep "Bank of Japan" and "US Treasury" as is. Also "Scott Bessent" is a name, keep as is. "Tokyo" is a city, but it's a proper noun, we can keep as "Tokyo" or translate to "도쿄"? Actually "Tokyo" is a proper noun, but in Korean we say "도쿄". I think it's fine to translate city names. But to be consistent, maybe keep "Tokyo" as is? The instruction says "Keep proper nouns (names, company names) in original form." It doesn't mention cities, but it's a proper noun. However, it's common to translate. I'll use "도쿄" for naturalness. But we need to decide. Let's check the original: "alongside Tokyo" - Tokyo refers to the Japanese government or the city? It likely refers to Japan, but it's used as a metonym. We can translate as "일본" or "도쿄". I'll use "일본" to be clear, but the original says "Tokyo", so maybe "도쿄" is fine. I'll use "도쿄" but that might be odd. Actually it says "Treasury Secretary Scott Bessent pledge further yen support alongside Tokyo" - meaning alongside the Japanese government. So we can say "일본 정부와 함께" or "도쿄와 함께". I'll
