Talking about the Months with Moons
These are not really Japanese words for the moon but in Japanese, the months are represented by the 月 Kanji pronounced gatsu. To figure out the name of a month you just add the number before 月. So, if you can count in Japanese you also know the months. For example, March would be 三月.
Those are the words for the moon in Japanese. If you want to learn more Japanese I reviewed a dictionary of grammar series which I personally recommend and use myself.
I also have several other posts on various topics on Japanese Universe if you are interested.
