The Controlled Rain Tiger Technique is a sensory ninjutsu that creates rain clouds saturated with Nagato's chakra. Each falling drop is linked to his essence. If the rain touches a person with foreign chakra, Nagato instantly learns of the intrusion, although the exact location of the intruder remains unknown — a specialist in large-area search is needed. The rain continues until Nagato cancels the technique. When leaving Amegakure, he always left this rain to watch over the village from a distance.
Since only Nagato and Konan know about the sensory nature of the rain, outsiders consider it an ordinary downpour and do not suspect that they have already been detected.
