30 Japanese Names With Kanji, Meanings, and JavaScript Data

If you're building a game, character generator, username tool, writing app, or simply working with Japanese names, you may eventually need structured Japanese name data.

A Japanese name isn't just a romanized word. The kanji can carry an important part of the name's meaning, and the same reading can sometimes have different kanji representations.

I recently organized Japanese name data with the name, kanji, reading, gender, and meaning so it can be used more easily in software projects.

Here are 30 examples from the Japanese name collection.

Japanese Names

The names and meanings above are based on the JapaneseNamer first-name directory, which organizes names by gender, style, kanji, reading, and meaning.

Why Structure Japanese Names as Data?

If you're building an application, storing names as plain strings isn't particularly useful.

Instead of:

const names = [
  "Haruto",
  "Sakura",
  "Ren"
];

you can keep the relevant information together:

const names = [
  {
    name: "Haruto",
    kanji: "陽翔",
    reading: "はると",
    gender: "male",
    meaning: "Soaring toward the sun"
  },
  {
    name: "Sakura",
    kanji: "桜",
    reading: "さくら",
    gender: "female",
    meaning: "Cherry blossom"
  },
  {
    name: "Ren",
    kanji: "蓮",
    reading: "れん",
    gender: "male",
    meaning: "Lotus"
  }
];

Now the same data can power a generator, search page, character creator, or API.

Filtering Names With JavaScript

Once the data is structured, filtering becomes straightforward.

For example, to get female names:

const femaleNames = names.filter(
  name => name.gender === "female"
);

console.log(femaleNames);

Or male names:

const maleNames = names.filter(
  name => name.gender === "male"
);

You can also search by meaning:

const flowerNames = names.filter(
  name =>
    name.meaning
      .toLowerCase()
      .includes("flower")
);

This is particularly useful for applications where the user chooses a theme before generating a name.

Generating a Random Name

A simple random generator only needs a few lines:

function randomName(names) {
  const index = Math.floor(
    Math.random() * names.length
  );

  return names[index];
}

console.log(randomName(names));

You can combine this with filtering:

function generateName(names, gender) {
  const filtered = names.filter(
    name => name.gender === gender
  );

  if (!filtered.length) {
    return null;
  }

  return randomName(filtered);
}

console.log(
  generateName(names, "female")
);

Now you have the foundation of a simple Japanese name generator.

Kanji Makes the Data More Interesting

One of the interesting things about Japanese names is that the kanji contributes meaning.

For example:

Haruto — 陽翔

The site describes 陽 as relating to the sun, positivity and warmth, while 翔 conveys soaring or flying. Together, the name is presented as "soaring toward the sun."

Similarly:

Kaito — 海翔

combines 海, associated with the sea, with 翔, associated with soaring.

And:

Sakura — 桜

uses the kanji for cherry blossom/cherry tree.

This makes structured name data much more useful than a simple list of romanized names.

Japanese Names Are Not Just Random Kanji

One thing I would avoid when building a Japanese name generator is simply combining random kanji because they "look Japanese."

A generated name should have a reasonable reading and a meaningful combination of characters.

This is why structured data is useful.

Instead of:

random character + random character

you have:

Name
↓
Kanji
↓
Reading
↓
Meaning
↓
Gender/style

That structure can then be used by a generator or search interface.

Other Useful Name Categories

A name dataset can also be organized around themes.

For example, JapaneseNamer's first-name directory includes categories such as:

• Nature
• Moon
• Flower
• Strength
• Light
• Ocean
• Sky
• Fire
• Peace
• Love
• Snow
• Wind
• Spring
• Summer
• Autumn
• Winter
• Blossom
• River

That opens up more interesting search possibilities than simply filtering by gender.

A user could ask for:

Female + Flower
Male + Strength
Unisex + Nature
Male + Ocean
Female + Moon

and receive names matching those themes.

Building a Developer-Friendly Dataset

A clean JSON structure could look like this:

{
  "name": "Haruto",
  "kanji": "陽翔",
  "reading": "はると",
  "gender": "male",
  "meaning": "Soaring toward the sun"
}

The same format can be consumed by:

• JavaScript
• TypeScript
• React
• React Native
• Python
• Node.js
• Game engines
• REST APIs

For a larger project, the data could eventually be split into separate files:

data/
├── names.json
├── male.json
├── female.json
└── unisex.json

What Can You Build With This?

Once the data is structured, there are quite a few possibilities.

1. Name Generator

Generate a name based on gender or theme.

2. Character Creator

Games can use the dataset to generate names for NPCs.

3. Username Generator

Names can be combined with numbers, words, or styles to create usernames.

4. Writing Tools

Authors can quickly find names based on a character's personality or theme.

5. Learning Projects

The dataset is also a nice beginner project for learning JSON, filtering, search, and APIs.

Explore the Full Collection

I used the JapaneseNamer name directory as the source for the examples in this article. It provides a browsable collection of Japanese first names with kanji, readings, meanings, and gender information.

You can explore the full collection here:

There is also an online Japanese name generator if you want to generate names instead of working with the data directly:

Final Thoughts

The interesting part of a Japanese name generator isn't the random-number function.

The interesting part is the data behind it.

Once names are represented with their kanji, readings, meanings, and other metadata, the same dataset can become the foundation for generators, search tools, games, APIs, and developer libraries.

That's the direction I'm exploring with Japanese name data: making it easier to discover names while also keeping the information structured enough to be useful in software projects.
