This is the worksheet for the Hiragana characters ZA, GA, PA, BA, and DA. You need the Adobe Reader to open the file. If you don't have this software, you can download it from the Adobe Website free of charge. And since this file is compressed, you need a utility to uncompress it. You can download one for free at Rarlabs (click English as language on the same page). After opening the file, you can print the worksheet then practice writing on it.
You can download this only if you are presently registered in the Japinoy.com free Nihongo lessons.
Enjoy!
