How to Say "I'm Hungry" or "I'm Thirsty" in Japanese

"YUU ASAKURA: I want to teach you two crucial sentences: I am thirsty and I am hungry. Those are very important. Unfortunately, we use different expressions. We don't have the equivalent word for thirsty and hungry. So let's start with thirsty one. This is a Japanese sentence: Nodo ga kawaka mashita. Its original meaning is nodo means throat. So nodo ga is making nodo as a subject and then kawaka mashita means it's dry. So we usually say: My throat is dry. So that means you're thirsty. So let's repeat after me. Nodo ga kawaki mashita. Yes, that's what you say when you are thirsty. So when you are hungry, it's this one: Onaka ga suki mashita. Onaka means stomach, your tummy, and suki mashita is it's empty. So when you are hungry, we say: My stomach is empty. It makes sense, right? So let's repeat after me, onaka ga suki mashita. So when you want to drink or eat, those two sentence very useful."
