Ever gone down a name rabbit hole and hit a wall at the letter X?
You are not alone.
Japanese names that start with x is very limited because japanese names do not really have an X sound, so a name search for it usually comes up empty.
Here is the fun part.
Old Portuguese missionary records from Japan used the letter X for the Japanese sh sound, which is why the word shogun was once spelled xogun.
That single fact opens the door to a real, honest list of Japanese names you can spell with an X.
In this list you will find boy names, girl names, first names, last names, and a few playful extras.
Every name here is a real Japanese name, just shown through that old X spelling.
By the end you will know exactly which ones to use, how to pick one, and how to make it your own.
Where The X Actually Comes From
Quick history lesson, kept short and simple.
When Portuguese priests reached Japan in the 1500s, they wrote down Japanese words using their own alphabet.
Portuguese did not have a clean way to write the sh sound, so they borrowed the letter X for it.
That is why old documents show words like xogun instead of shogun, and Ximabara instead of Shimabara.
So when you see an X name on this list, picture it as a sh name wearing an old fashioned spelling.
It is a real name with real roots, not something pulled out of thin air.
This matters for accuracy.
A lot of name lists online just make up words and slap kanji meanings on them.
That is not helpful, and it is not respectful to a real language either.
Every name below traces back to an actual Japanese given name or surname.

Fantasy Japanese Names That Start With X
Fantasy writers, this section is for you.
These are built by pairing real Japanese name roots together, the same way many actual Japanese names are formed.
They lean bold and mythical, but they are grounded in real word pieces, not random letters.
- Xiryu (built from words meaning true and dragon)
- Xirogane (the old word for silver)
- Xinra (a real surname, often used for strong sounding characters)
- Xiden (means purple lightning, a striking image)
- Xishimaru (a classic warrior style name pattern)
- Xura
- Xindo (echoes the word for a path or way)
- Xizen (relates to the idea of nature)
- Xikaze (built from wind)
- Xikage (built from shadow)
A tip if you are building a character.
Pick one root that describes their personality and one that describes their power or role, then blend them the way Xiryu blends true and dragon.

- Xiro (means white)

Names that work no matter who is wearing them.
- Xion
- Xinobu
- Xu
- Xo
- Xiki
- Xizu
- Xido
- Xura
Xion and Xinobu are the two most flexible picks here, comfortable on a boy, a girl, or a character whose gender is left open on purpose.
How To Pick One That Actually Fits
Say it out loud a few times, with the sh sound instead of the letter X.
Xota becomes Shota, Xizuka becomes Shizuka, and suddenly it sounds like a name a real person could have.
Think about where it will live, a birth certificate, a game profile, a novel, or a group chat.
A name for a fantasy character can be bolder than a name for a baby.
If you want it to feel authentic, keep the sh sound in your head the whole time you are choosing.
Tips For Making It Memorable
Pair a short name with a longer surname, or the other way around, so the rhythm stands out.
Xota Ximizu rolls off the tongue easier than two short or two long names stacked together.
Give it a small story, even a one line backstory helps a name stick in a reader’s mind.
Say it in a sentence before you commit, since some names look good written down but feel clunky spoken out loud.
Building An Identity Around The Name
If this is for a team, a group chat, or a fictional clan, the name is just the starting point.
Add a small phrase or motto that echoes the meaning, so Xiryu the true dragon might carry the line stands firm, breathes fire.
Match a color or symbol to the meaning too, silver for Xirogane, a droplet icon for Xizuku.
Small touches like this turn a name into something people actually remember and repeat.
Frequently Asked Questions
Do Japanese names usually start with the letter X?
No, not in modern Japanese.
The X spelling comes from old Portuguese records that used X for the Japanese sh sound.
Are these names real in Japan?
Yes, in their original form.
Xota is really Shota, Ximizu is really Shimizu, and so on, spelled the historic way.
Can I use these names for characters or stories?
Absolutely, this is one of the best uses for them.
The historic X spelling gives your character a name that feels both real and a little mysterious.
Do these names have actual kanji meanings?
The underlying Sh names do carry real kanji, and the meaning can shift depending on which kanji a family chooses.
That is why exact meanings are not fixed the same way a single English word is.
Are any of these unisex?
Yes, Xion and Xinobu in particular are used comfortably by both boys and girls in their original Sh spelling.
Is it culturally respectful to use these names?
Using a real name with an honest explanation of where the spelling comes from is respectful.
The line gets crossed when a list invents fake words and calls them Japanese, which this list avoids.
Can I name my child one of these?
You can use the original Sh spelling for a birth certificate, since Xota and Shota are the same name.
The X version works best for creative projects, usernames, or characters rather than official paperwork.

The letter never belonged to modern Japanese, it belonged to old Portuguese records trying to capture a Japanese sound, and that small piece of history is what makes this list real instead of invented.
From Xota and Xizuka to Ximizu and Xiryu, every name above traces back to an actual Japanese name, just dressed in its historic spelling.
