The Kanji at a Glance
The kanji for dragon exists in two forms, and both are correct Japanese. This is not a case of one being right and one being wrong.
龍 is the traditional form, sixteen strokes, dense and ornate.
竜 is the modern standard form, ten strokes, cleaner and simpler.
- On’yomi: RYUU
- Kun’yomi: tatsu
- Strokes: 16 for 龍, 10 for 竜
- Core meaning: dragon
竜 is the jouyou kanji, the officially designated form taught in schools and used in newspapers. 龍 is the older kyuujitai shape, retained as a jinmeiyou kanji for personal names and still overwhelmingly preferred in calligraphy, temple carving, tattoo work, and anywhere the goal is presence rather than legibility.
Meaning and Nuance
The Japanese dragon is not the hoard-guarding menace of European legend. It is a water deity: a serpentine, wingless, clawed being associated with rain, rivers, the sea, and protection. Shrines and temples across Japan keep dragon carvings above their entrances and dragon-mouthed fountains at their purification basins.
- 竜巻 (tatsumaki) is a tornado, literally “dragon coil.”
- 恐竜 (kyouryuu) is a dinosaur, “fearsome dragon.”
- 龍神 or 竜神 (ryuujin) is the dragon god, the sea deity of Japanese myth.
- 登竜門 (touryuumon) means a gateway to success, from the legend of a carp that climbs a waterfall and becomes a dragon. It is the same story behind the koi tattoos you have seen.
That last compound explains a lot about why dragons appear so often in Japanese tattooing. The dragon is what the carp becomes after the hard climb. For the full picture of the creature itself, see our page on the japanese dragon.
As a Tattoo
龍 is the form most tattoo clients want, and for good reason. Sixteen strokes packed into one square gives it real visual weight, and at a decent size it reads like a piece of architecture. 竜 is not a lesser choice, just a quieter one, and it suits minimal or small-scale work where 龍 would collapse into a blot.
On script, be careful. Simplified Chinese uses 龙 for dragon, a form that does not exist in Japanese at all. It circulates widely in tattoo flash sheets and online generators. If your reference shows 龙, it is Chinese, not Japanese. Traditional Chinese uses 龍, the same character as Japanese kyuujitai, so that one is shared.
Size is the real constraint. 龍 has sixteen strokes crammed into a single glyph, and tattoo ink spreads over decades. Placed too small, the internal lines will merge into a dark mass within ten years. Give it space: the outer forearm, shoulder, calf, or as a single anchoring character in a larger back or sleeve piece. If you want it on a wrist or a finger, use 竜.
Many people pair the character with dragon imagery rather than using it alone, and that combination usually reads better than either element by itself. Confirm with a native speaker before you ink, and confirm with your artist that the stencil is at the final size.

FAQ
What is the kanji for dragon?
The kanji for dragon is 龍 or 竜, both read ryuu in on’yomi and tatsu in kun’yomi. 竜 is the modern standard form with ten strokes, and 龍 is the traditional form with sixteen. Both are correct Japanese, and 龍 is the one usually chosen for tattoos and calligraphy.
Should I use 龍 or 竜 for a tattoo?
Use 龍 if you want density and presence and you have room for it, which is the usual choice. Use 竜 for small or minimal work where sixteen strokes would blur together as the ink ages. Neither is incorrect.
Is 龙 the same as 龍?
龙 is the simplified Chinese form. It is not used in Japanese at all. If a design shows 龙 and claims to be Japanese, the source is wrong. Traditional Chinese shares 龍 with Japanese, so that form works in both.
What does ryu mean in Japanese?
Ryuu written as 龍 or 竜 means dragon. Be aware the same syllable maps to other kanji entirely: 流 (ryuu) means flow or current, and 竜 versus 流 versus 隆 are different words with different characters. If someone has told you “ryu means dragon,” check which character they mean.
