kizuna

An op-ed piece by Kan Naoto souridaijin (N. Kan, 'Prime Minister' of Japan), published in the Washington Post on April 15th. Here is the concluding paragraph:

I believe that the best way for Japan to reciprocate the strong kizuna and cordial friendship extended to us is to continue our contribution to the development of the international community. To that end, I will work to the best of my ability to realize a forward-looking reconstruction that gives people bright hopes for the future. I would wholeheartedly appreciate your continued support and cooperation. Arigatou.

In Japanese, kizuna means "the bonds of friendship"; Arigatou means "thank you".
