Neji's eyesight. It's not 359 degrees.
I don't see how Neji's eyesight could be measured in degrees. Neji has full 360 degrees but with a small blind spot. I see everyone saying how Neji can't see directly behind him or some crap like that, but it's not true. If Neji was trapped in a ball, he would be able to see the entire ball clearly except for one small, circular portion of it where his blind spot is.
Just trying to clear some things up. Correct me if I'm wrong. |

Yes, that's exactly what I'm saying, he can't see one point, and it's directly behind him, 180 degrees from between his eyes. If you've read the manga, then it says so, and being as I don't watch the anime, I have no idea were it's at, but it'll eventually (if it hasn't already) say it in that as well.

Actually it is true, as they even show it in the manga, they show where Neji can't see (right behind him) the area gets wider the further away it gets from Neji, it makes a small pie slice, If you overlay a circle over that, you'll see that Neji doesn't have 360 vision |

A sphere is composed of one circle rotated around a point that is also its center. A measurement of location on a circle is the degree. Each degree is defined as 1 360th of a circle. This is not logical, however it is defined as such. Thus a 1 degree blind spot on a sphere would be a circle 1 degree in diameter perched on the surface of the sphere. If the sphere was compressed to infentesimal radius then slowly expanded to a range of 50 m, the 1 degree circle on its surface would describe a slowly expanding cone. Thus the blind spot.
The flaw you have picked up on is the fact that there is no defined method of describing area on the surface of a circle, that is readily available to the average joe. Me being one of them. Thus for those of us smart enough we make the afore described leap of logic. For the less intellegent among us, the description is merely looked at like a cirle with a spot missing. For those some where inbetween the whole thing makes no sense. |

I don't know why manga readers didn't see the picture of Neji's eyesight that showed a circle (blindspot) going off into the distance diagonally (allowing him to see like 9/10 of what's directly behind him). Oh, and that pie example. It would be like that, but not from top to bottom view. It would be like that from the side view. Spoiler for Picture of Neji's Blindspot from the manga:

Steradian
The steradian (symbolized sr) is the Standard International (SI) unit of solid angular measure. There are 4 pi, or approximately 12.5664, steradians in a complete sphere.
A steradian is defined as conical in shape, as shown in the illustration. Point P represents the center of the sphere. The solid (conical) angle q, representing one steradian, is such that the area A of the subtended portion of the sphere is equal to r2, where r is the radius of the sphere.  A general sense of the steradian can be envisioned by considering a sphere whose radius is one meter (r = 1m). Imagine a cone with its apex P at the center of the sphere, and that intersects the surface in a circle (shown as a red ellipse, the upper half of which is dashed). Suppose the flare angle q of the cone is such that the area A of the spherical segment within the circle is equal to one meter squared (A = 1 m2). Then the flare angle of the cone is equal to 1 steradian (q = 1 sr). The total surface area of the sphere is, in this case, 12.5664 square meters (4 pi times the square of the radius). Based on the foregoing example, the geometry of which is independent of scale, it can be said that a solid angle of 1 sr encompasses about 1/12.5664, or 7.9577 percent, of the space surrounding a point. The number of steradians in a given solid angle can be determined by dividing the area on the surface of a sphere lying within the intersection of that solid angle with the surface of the sphere (when the focus of the solid angle is located at the center of the sphere) by the square of the radius of the sphere. The above definition came from techtarget.com. |

yhrt98 That's just fantastic but has little to do with the question.
It's just a fact that he has a small blind spot. It was never specified in the Manga that Neji has 360 - 1 degrees of sight but it's just easy to call it that. Wheteter its a little over 1 degree or under doesn't matter. We all know what it means.

I take yhrt98 simply forgot to add the conclusion, which is Neji's blind spot is immediately behind p (given Neji stands on p) and further the target is away from p, better the chance for Neji to notice the target.

In response to those that have been nitpicking about the degrees thing. I already said that it was insufficient to describe the phenomena. THus the steridian system, a system that I alluded to not knowing. As to 359° I think it was mentioned once or twice by Ten ten. HOwever one can think of this in degrees if they think of an circle with 1/360 of its circumferance missing, rotated around the line that is formed by the focus of the circle and the point in the dead center of the gap. I hope its clearer now what I said in my first post.
And yes there is a picture, and yes it is exactly described by this. There are of course scale problems but unless those were there I would be very disturbed. |

I think the problem here is that some people don't understand the concept of degrees, and then some people got too mathematical on it. Let me boil this down.
DEGREES: Applies to circles and spheres. 360 Degrees: Front, Back, Top, Bottom, Diagonal, and EVERY SINGLE DIRECTION YOU CAN POSSIBLY CONCEIVE OF. 359 Degrees as applies to Naruto: Probably not mathematically accurate, but it means that Neji can see in all directions, except for one tiny sliver. May or may not be exactly 359 degrees, mathematically speaking, but it stands for super high degree of vision with a miniscule, normally insignificant blind spot |

 The anime has been hinting that he's not perfect for a while too ... the whole birdcount scene with Tenten. I don't think that Neji knew about his blindspot before the spiderman fight anyway. A slight headshift would reveal what's in the blindspot because the blindspot shifts around. If he would just keep moving around it would become much harder to get him there ... unless ofcourse Neji thought his vision was perfect and stood still for too long facing the same direction. |
