This is a more practical application of the Multi-Size Technique. Rather than increase the size of their entire body, the user increases the size of only specific body parts, typically the arms and legs. Because of the larger size, physical attacks made with the expanded limbs do greater damage than normal. The limbs' growth is very fast, giving users a way of taking opponents by surprise. As with other techniques of the Akimichi clan, its chakra requirements are quite high, to the point that, in Part I, Chōji takes one of the Three Coloured Pills before using this technique.
- In Naruto: Ultimate Ninja 2, Chōji uses this technique under the name "Super Fly Swatter" (超ハエたたき, Chō Haetataki).
