Nature Tattoo

Tattoos are also placed on animals, though very rarely for decorative reasons. Pets, show animals, thoroughbred horses and livestock are sometimes tattooed with identification and other marks. Pet dogs and cats are often tattooed with a serial number (usually in the ear, or on the inner thigh) via which their owners can be identified. Also, animals are occasionally tattooed to prevent sunburn (on the nose, for example). Such tattoos are often performed by a veterinarian and in most cases the animals are anesthetized during the process. Branding is used for similar reasons and is often performed without anesthesia, but is different from tattooing as no ink or dye is inserted during the process.
In Japan, tattoos are strongly associated with a particular organized crime organization known as the yakuza, particularly full body tattoos done the traditional Japanese way (Tebori). Many public Japanese bathhouses (sentō) and gymnasiums often openly ban those bearing large or graphic tattoos in an attempt to prevent Yakuza from entering. The Government of Meiji Japan had outlawed tattoos in the 19th century, a prohibition that stood for 70 years before being repealed in 1948.
