Japanese names that mean sea or ocean

Japanese names of the sea, waves, shores and harbours, from Kaito and Umi to Minato, recently the No. 1 boy name in Japan.

海 umi, kai: sea湊 minato: harbour凪 nagi: calm sea

Japan is an island country, and the sea runs through its names. 海 (sea) gives Kai, Kaito and Umi, and girls' names like Nanami (七海, seven seas). 洋 is the wide ocean, 波 is a wave, 汐 the tide and 帆 a sail.

The harbour has become especially fashionable. 湊 (Minato) means a harbour where ships gather, and it reached the top of the boys' ranking in recent years. 凪 (Nagi), the stillness of the sea when the wind drops, and 渚 (Nagisa), the shore, are popular for their calm.
