Peninsula east of the Yellow Sea

KOREA

This land is divided by the 38th parallel and is known for its vibrant K-pop culture and historic dynasties like Goryeo.

This clue points to Korea because it’s the well-known peninsula located directly east of the Yellow Sea, separating China from the Korean Strait. The answer is straightforward—no wordplay or tricks—just a direct geographical reference to the landmass that includes both North and South Korea. If you’re picturing a map of East Asia, Korea is the obvious land jutting out into the sea in that spot.
