"Gakugyou jyouju" translates as "Success in Studies", and is a common protective phrase written on charms in Japan. Students often tie these charms, called "omamori", to their bags and carry them around throughout the school year.
This poster is suitable for printing on 8.5" x 11" paper, and it may be framed and posted in your class room as a sort of good luck charm for all your students. (I cannot guarantee that this phrase will bring educational success to all your students, but I certainly have my fingers crossed. I am not a Buddhist priest, after all. At the very least, it will be a conversation piece!)
Also included is a PNG file of the Kanji characters, so that you may "stamp" this image on anything you like. (PNG files have transparent backgrounds.)
