Can I convey a meaning in a name with only kana? If not, what Kanji should I use for the name "Mimi" to convey "Beautiful Ocean"?


I'm working on a logo design project and was thinking of using the name "Mimi"
as I saw [somewhere](https://en.pon-navi.net/nazuke/name/reading/f/mimi) that
it might represent "beautiful ocean".

I don't understand much about the Japanese language, I'm reading a lot about
it, but what I would like to know is: would I be missing the meaning
"beautiful ocean"/"beautiful sea" of ミ{mi}ミ{mi} if I used only katakana?

For the logo to continue having the meaning I want, do I need to use a
specific way of writing?

Yes. Whether you use hiragana (みみ), katakana (ミミ) or romaji (Mimi), no one
would think you're referring to the ocean. If anything, people would imagine
[this word](https://jisho.org/word/%E8%80%B3), which is not what you want to
convey.

If you heard that Mimi meant "beautiful ocean" from someone, I think that
person had the kanji **美海** in mind, which is one of the [many combinations of
kanji that can be assigned to the name
"Mimi"](https://b-name.jp/%E8%B5%A4%E3%81%A1%E3%82%83%E3%82%93%E5%90%8D%E5%89%8D%E8%BE%9E%E5%85%B8/f/yomi/%E3%81%BF%E3%81%BF/).
美海 indeed carries the meaning of "beautiful (=美) ocean (=海)". I would like you
to read [this Wikipedia
article](https://en.wikipedia.org/wiki/Japanese_writing_system) about the
Japanese writing system, but the kanji 美海 is mandatory to convey the meaning
of "beautiful ocean". If you write it in hiragana, katakana, or romaji, the
intended meaning won't be conveyed.

Also note that 美海 is a girl's name, not an ordinary word defined in regular
dictionaries. It doesn't make much sense outside person names. If you used the
kanji 美海 in your logo, people would wonder if it's an anime character goods or
something. What's worse, "Mimi (みみ)" is not the only reading of the kanji 美海;
it can be read also as
[みう](https://ja.wikipedia.org/wiki/%E8%97%A4%E8%B0%B7%E7%BE%8E%E6%B5%B7),
[みうみ](https://ja.wikipedia.org/wiki/%E4%BB%B2%E7%BE%8E%E6%B5%B7) or in other
rare ways. A common workaround is to include both kanji and kana/romaji in
your logo, as shown [here](https://japanese.stackexchange.com/a/43797/5010)
and [here](https://japanese.stackexchange.com/a/62488/5010).
