Hi there, this is Junko from Japan! If you’re looking for baby names regarding ocean or sea, how about the ones with Japanese origins?
Here I share you with beautiful 8 names that mean ocean or that are related to the sea. All the words are carefully hand-picked by me, a native Japanese speaker. I guarantee they’re all correct, natural, and meaningful!
KAI: Ocean, Sea

We call ocean or sea UMI in Japanese. UMI is possible for a baby name, but it’s not so common. Instead, I want to offer another reading of the same symbol, KAI, which is more suitable for a given name.
The name KAI is gender-neutral, but mainly used for boys.
MINATO: Port, Harbor

MINATO means “port” and “harbor.” Though it doesn’t directly mean ocean, this is a popular name for boys with its beautiful and refreshing sound.
NAGI: Calm, Lull

NAGI represents the calm seas with no waves in Japanese. This name is getting popular in recent years. It’s unisex and is well suitable for both boys and girls.
NAGISA: Water’s Edge

NAGISA is the word for water’s edge, and it’s sometimes translated as “beach” or “shore.” But we have other words for “beach” and “shore,” and NAGISA gives more sophisticated and poetic impressions among them.
Since the NAGISA symbol clearly reminds us of seas and oceans, it’s a popular name for babies born in summer. It’s gender-neutral, but I feel it’s more commonly used for females as it has a gentle connotation, making it more suitable for women.
NAMI: Water Wave

NAMI is a modern and popular name for baby girls. The word NAMI stands for “water wave” while we can give other meanings by using various Kanji combinations.
Generally, the Kanji symbol for “beauty” is selected for the MI sound. It’s a feminine and adorable name!
NANAMI: Seven Seas

NANAMI isn’t a general word, but the name for girls. We can give the Kanji combination for “seven seas” to it. NANA is “seven,” and MI is a part of UMI which means “sea.”
It’s a name with positive and energetic impressions!
USHIO: Ocean Current, Ebb and Flow of the Tide

This symbol represents the changing nature of ocean waves over time. The left part with three dots pictures “flowing water,” the middle one is “sun,” and the right one depicts “shore,” making the entire character mean moving tide.
This is a name with cool and sturdy impressions and is used for baby boys.
WATARU: Voyage, Sailing

This one is for boys, too. The symbol is used for Japanese words meaning “voyage” and “sailing.” It has several ways of reading, and WATARU is one of them which is the most suitable for a name.
The Japanese word WATARU also has the meaning “cross a long distance,” which gives the name WATARU free-spirited and generous impressions.
