They're probably not trying to use Japanese writing, but the writing of certain languages from countries around China that had a lot of contact with them or were outright influenced by China (like Japan) in the past, do occasionally use the traditional Chinese characters for their own language, isntead of the simplified Mandarin that China uses today.

If you've ever watched/read Naruto, you can see that the Japanese symbol for "fire" that the Hokages in Konoha have on their office building is the exact same character that is used in Avatar for the word fire.
