Message to Students“Strong body makes strong mind”
…This is the term given from an English teacher when I was a SFC student. To explore its fundamental meaning, I might have been pursuing the study of brain and body.

Dear all SFC students! Please enjoy your SFC life by making full use of your brain and body, and achieve the ability to open the way to the future by yourself!!
