Leather
noun
The kanji and the word are exactly the same. That means they share meanings as well.
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you remember:
Leather is the skin of a cow, right? How do you say "skin" in Japanese? Remember 皮 aka かわ? It has the same reading as that, and they're both skin, so hopefully that makes it easier to remember.
これは本物の革じゃありません。
This is not real leather.
革のカバンを作るために、皮を革に加工しました。
I processed the hides into leather in order to make a leather bag.
フグは日本でワニ革のサンダルを買った。
Fugu bought crocodile skin sandals in Japan.
