Meaning
The kanji 革 (kaku, kawa) is unique because it represents two main, yet closely related, concepts: leather and change/reform. At its core, 革 is a pictograph depicting an animal hide that has been stripped, stretched, and meticulously prepared. You can visualize the top part resembling the animal's head or horns, the middle section as the body spread out, and the bottom strokes as the tail and legs. This vivid imagery directly conveys its primary meaning of 'animal skin' or, more specifically, 'leather'—a processed hide. Transforming a raw animal hide into durable leather demands a fundamental alteration and renewal. This intricate process—changing something from its raw state into a refined, new product—is precisely why 革 also came to mean 'to change,' 'to reform,' or 'to innovate.' It suggests a fundamental, often thorough, alteration rather than a superficial one, much like how hide is fundamentally changed into leather. Taught in the 6th grade in Japan, this 9-stroke kanji is a good example of how visual elements can convey deep meaning.

Memory Tip
To remember 革, visualize an animal hide stretched out on a frame. The top part can resemble a head, the middle square shape forms the body, and the bottom strokes represent the legs or tail. Imagine the entire process of transforming this raw hide into durable, functional leather. This intensive processing marks a profound 'change' or 'reform' from its original state. So, whenever you see 革, think of a 'leather' hide undergoing a radical 'change' to become something new. This dual imagery—of the material and its transformation—will reinforce your understanding of both main meanings and readings.
