- Name: Partial Multi-Size Technique (部分倍化の術, Bubun Baika no Jutsu, Partial Expansion Jutsu)
- Type: Hidden, No rank, Supplementary
- Users: Akimichi Clan
The Partial Multi-Size Technique is technique unique to the Akimichi Clan. Like the standard Multi-Size Technique, it expands the body, but expands parts of the body as opposed to just the stomach. Skilled clan members can alter the size of their body to a large scale with little trouble. Those with lesser skills can use the Hōren (Spinach) pills to do the same. With the larger body parts, the user strength increases.
