Getting a sleeve tattoo is a huge commitment that requires more planning and time than a typical piece of body art. You cannot impulsively choose an image from a binder or the Internet and stick it on your arm. If you want a decent-looking design that doesn't suck and makes you rethink your life choices, then you need to do ample research about the process, think about a theme and style, shop around for reputable artists, and then sit down with the artist of your choice to design the tattoo.
The Japanese word irezumi means "insertion of ink" and can mean tattoos using tebori, the traditional Japanese hand method, a Western-style machine or any method of tattooing using insertion of ink. The most common word used for traditional Japanese tattoo designs is horimono. Japanese may use the word tattoo to mean non-Japanese styles of tattooing.
