Samurai and gods are always very popular in traditional Japanese sleeve tattoos. These designs of course feature either fierce samurai in the heat of battle of gods fighting off evil spirits. Either way you end up with a way cool dude tattoo. What can be more guy then a man swinging a huge katana sword and slaying a dragon or a demon. It is the ultimate. The reason the Samurai is so popular in Japanese tattooing and traditional arts is that the samurai is seen to embed everything that is important to the Japanese male. The samurai carries the Japanese culture as well as being a strong and fierce warrior in battle yet is always mindful and follows the code of bushido. This is what every Japanese male wants to be deep down.
