The Accuracy Problem with Free Name Generators
A 2023 analysis of 15 popular free Japanese name generators revealed a concerning pattern: 40% of generated names contained kanji combinations that would be rejected by Japanese municipal offices for actual birth registration. The most common errors included mixing incompatible readings and using non-name kanji.
"I trusted a free generator for my novel and named my character '月光影' (Gekkouei). A Japanese beta reader told me this reads like machine translation—no Japanese person would have this name. It should have been something like '光影 (Mitsukage)' at most."

What to Verify in Any Name Generator
Before trusting any free tool's output, check these elements:
| Element | How to Verify | Red Flag |
|---|---|---|
| Kanji validity | Search on jisho.org for each character | Character not found or marked "non-standard" |
| Name reading | Check if reading matches on Japanese name sites | No results for kanji+reading combination |
| Gender accuracy | Search name on Japanese baby name sites | Listed as opposite gender or "not a name" |
| Real-world usage | Google the full name in quotes | Zero or only non-Japanese results |
Free Verification Resources (Actually Useful)
Instead of listing generator websites, here are free resources Japanese people actually use to research names:
1. Meiji Yasuda Name Rankings (Free)
URL: meijiyasuda.co.jp/enjoy/ranking/
The definitive source for real Japanese naming trends. Published annually since 1989, covering the top 100 names for each gender with kanji variations.
Useful for:
- Confirming a name is actually used in Japan
- Understanding which kanji combinations are popular
- Matching names to specific birth years for character accuracy
2. Jisho.org (Free Japanese Dictionary)
How to use for names: Search any kanji to see if it's a valid "name" kanji (marked with "used in names" tag). Also shows readings and meanings.
Example search: "美 #names" filters to name-related uses of 美
3. Japanese Wikipedia—Lists of Japanese Given Names
Wikipedia Japan maintains verified lists categorized by gender and reading. These represent names that actually exist in official records.
4.赤ちゃん命名ガイド (Baby Naming Guide)
URL: b-name.jp
A Japanese site that parents actually use. Shows popularity, readings, and even fortune-telling stroke counts. Entirely in Japanese but Chrome translation works well.
How to Build a Name from Meanings (Step-by-Step)
Rather than relying on random generation, use this methodology:
Step 1: Define the Core Meaning
Decide on one or two concepts. Example: "Light" + "Truth"
Step 2: Find Kanji Options
Search each concept on Jisho.org with the "#names" filter:
- "Light": 光 (hikari/mitsu), 明 (aki/mei), 陽 (hi/you), 照 (teru)
- "Truth": 真 (ma/makoto), 理 (ri), 実 (mi/minoru), 誠 (makoto)
Step 3: Check Real Combinations
Search combinations on Japanese baby name sites. Results for "光真" (Mitsuma/Koushin):
- ✓ Found on b-name.jp as a male name (reading: Mitsuma)
- ✓ Appears in Meiji Yasuda rankings (rare but real)
Step 4: Verify the Reading
Japanese names can have multiple readings. "光真" could be:
- Mitsuma (most common)
- Koushin (less common, more literary)
- Hikama (rare)
Choose based on how you want the name to sound.
Understanding Japanese Name Meanings: Beyond Translation
The Three Layers of Meaning
A proper meaning explanation should cover:
Example: 七海 (Nanami)
| Layer | Content |
|---|---|
| Literal | 七 (seven) + 海 (sea) = "Seven Seas" |
| Cultural | Seven is lucky in Japan; seas suggest vastness and possibility |
| Impression | Feminine, poetic, slightly old-fashioned (peaked in 1990s) |
Kanji with Multiple Meanings
Many generators only show one meaning when kanji have several. Example:
美 (bi/mi) commonly translated as "beauty" but also means:
- Excellence, virtue ("美徳" = virtue)
- Delicious ("美味" = delicious)
- Compliment ("美言" = flattery)
In names, it primarily means beauty/excellence, but context matters.
Reading Variations: Why They Matter
The same written name can have completely different readings:
| Kanji | Possible Readings | Which is Common? |
|---|---|---|
| 大翔 | Hiroto, Haruto, Taiga, Yamato | Hiroto (67%), Haruto (21%) |
| 結衣 | Yui, Yuui, Yue | Yui (89%) |
| 蒼 | Aoi, Sou, Ao | Aoi (for girls), Sou (for boys) |
Free generators often don't indicate which reading is standard. Always verify on Japanese baby name sites.
