There are many relief efforts being established to help Japan. A group of bentoists have set up bento4japan... you can donate money, buy bento supplies with the profits going to help Japan, or you can add something to auction!
Check out bento4japan!
I never knew much about Japan (or was very interested in it) until I started learning about bento and watching anime. Now that I'm very interested in the culture, the tragedy has hit hard.
