Barrier Method Formation

An array of four explosive tags are jointly placed around the boundary of an area. If anyone or anything happens to walk through the boundary, the seals will detonate when the intruder reaches the center, killing the imprisoned target.

Trivia

 * In the English dubbed version, Neji incorrectly claims that five tags are used in this technique, despite a later cartoon depiction of how it is used showing four.
 * In Naruto Shippūden: Ultimate Ninja Storm Revolution and Naruto Shippūden: Ultimate Ninja Storm 4, Iruka Umino uses five tags in a circular formation when performing the technique. Additionally the tags will auto-detonate after a set period.
