Tattoo motifs of wind and water; like those of bamboo and pine, are trans-seasonal. They are often employed as unifying elements across the background of a tattoo. Connecting different tattoo elements with an overarching design is a defining element of Japanese tattoos; this is an important difference compared to Western tattoos, which traditionally are isolated images on the skin. Wind and water motifs make that connection.
Note that the Japanese language uses the same word (taka) for both falcons and hawks. The visual difference is that falcons have a notched beak, while hawks do not. Taka are strong, with a piercing gaze. This explains why the bird has long been a symbol of the samurai , and the bird of prey is a common design on men's kimono. In irezumi, the bird of prey is paired with snakes, with the taka either swooping down to seize the snake in its beak, or with the reptile wrapped around its body. It's a depiction of killing or being killed. Thematically, the motifs is much deeper. The taka represents power, and the snake is longevity . The bird is also auspicious . Dreaming of a taka, Mount Fuji, and an eggplant on the first day of a new year is considered lucky. In the dream, the taka represents strength, power, and the ability to fly high .
