Translation guide
In Japanese, 'large wave' can be expressed through several words that differ in nuance, context, and scale. The most common and versatile term is 大波 (ōnami), literally 'big wave'. For ocean waves, especially in surfing or poetic contexts, 波濤 (hatō) or 怒涛 (dotō) convey a more dramatic, literary feel. In scientific or disaster-related contexts, 津波 (tsunami) refers specifically to a tsunami, a large and destructive wave caused by seismic activity. This guide helps learners choose the right expression based on the situation.
