In Japan, the ocean isn’t just a body of water—it’s memory, myth, and movement. It surrounds the country physically, yes, but also shows up in its language, art, and belief systems. From quiet fishing villages to Shinto rituals at coastal shrines, the sea has always held a kind of quiet authority. It’s no wonder that so many Japanese names are drawn from it.
Names like Umi (海) or Nami (波) aren’t just aesthetic—they carry weight. They hold centuries of symbolism: peace, power, change. For many Japanese parents, choosing an ocean-related name is a subtle way of passing on those ideas to the next generation. It’s not flashy—it’s intentional.
