太平洋（たいへいよう、taiheいyou）
- Pacific Ocean

太平洋 means "Pacific Ocean." It is the largest and deepest ocean on Earth, covering about 30% of the planet's surface. The word combines two kanji, 太 (たい - tai) meaning "great" or "large," 平 (へい - hei) meaning "peace" or "calm," and 洋 (よう - yō) meaning "ocean."

The name was given to the ocean by the explorer Ferdinand Magellan, who encountered relatively calm seas during his voyage across the ocean in 1520. He named it "Mar Pacífico," which translates to "Pacific Sea" in Spanish. The Japanese word 太平洋　 is a direct translation of this name, reflecting the perceived calmness of the ocean at the time. The choice of the characters 太 (tai) for great, 平 (hei) for calm, and 洋 (yō) for ocean beautifully captures the essence of the ocean's vastness and perceived peaceful nature.
