Yes! In the *Kojiki* and *Nihon Shoki* chronicles, Ryūjin rules the sea with tide jewels, hence the popularity of dragon and wave motifs on sword fittings during the Edo period.

Ryūjin, the tide dragon

In ancient Japan, Ryūjin, the dragon god of the oceans, ruled the tides thanks to two legendary jewels. Depicting a dragon on a saya is not merely decorative; it invokes this protective power linked to the sea. Imperial chronicles mention these "tide stones" that Ryūjin gives to heroes to tame the waves, while Edo-period workshops produced numerous tsuba and fuchi-kashira adorned with dragons among the waves. This iconography reminds the swordsman that true strength is fluid, like water, and that the blade must "breathe" to the rhythm of the swell. Even the undulating hamon, notare or midare, evokes the surface of the ocean. On a katana named "Ryūjin," the dragon screen print becomes a maritime talisman, between mythical memory and martial aesthetics.
