Okay Boys and Girls! It's time for the FIRST SaruDama Japanese Language Lesson (SJLL!!) brought to you by, well, me.
First off, let's focus on the name of our task. In other words, how do you say "Japanese Language" in Japanese? The answer is Nihongo (ni-hon-go). We call that pronunciation and writing system ROMAJI since if utilizes only Roman characters. And that's cheating.
You can correctly "spell" the word nihongo like this 日本語 or this にほんご.
If you can aesthetically sense or recognize a difference between the appearance of these two versions, you are well on your way of distinguishing amongst the three (3) writing systems of the Japanese.
