Did some investigation over lunch using the Chinese hanzi characters instead of kanji.
Looks like these characters: ä¿æŠ¤
I think these translate to (respectively):
ä¿ - protect, safeguard, defend, care
护 - protect, guard, defend, shelter

Edit: looks like I was a little late and Malador beat me to it....
