Translation guide
Japanese has several ways to express abdominal pain, ranging from general terms to specific medical vocabulary. The most common everyday word is 腹痛 (ふくつう), but in casual conversation people often use お腹が痛い (おなかがいたい) or simply お腹が… to describe a stomachache. More precise terms exist for upper vs. lower abdominal pain, and there are also onomatopoeic expressions for sharp or dull pain.
