Variant spelling using 浪 (waves); less common than 卯波.
Compound of 卯 (u, 'the Rabbit, the fourth sign of the Chinese zodiac; the fourth month of the lunar calendar') + 波 (nami, 'wave'). The name refers to the seasonal waves that appear around the fourth month of the old calendar (late May to early June).
