This particle sounds like 'wa'. But you always write it as 'は'. This is an old rule. Just remember it.
This is different from 'ga'. 'Wa' tells us what you are talking about. This is usually something you already know. 'Ga' tells us who or what does an action. This is new information. For example, 'zou wa hana ga nagai' means 'Elephants, their noses are long'. This is a general fact. 'Zou ga kita' means 'An elephant came'. This tells you who came.
Watch out: People often use "wa" when they should use "ga." Imagine someone asks, "Who came?" You should say, "Mr. Tanaka came." Use "ga" here. If you say "Mr. Tanaka came" with "wa," it means "Mr. Tanaka came, but others did not." This is a different meaning.
Use this when you want to tell someone what you are talking about. It points to the main subject. Then you say something new about that subject.
