Kadoya Sesame Oil, recognizing these changes in lifestyle, is working on proposing ways to use "Pure Sesame Oil as a finishing touch" that can add satisfaction to daily meals without requiring much effort. "Sesame Oil Egg Over Rice Soy Sauce" focuses on egg over rice, a breakfast staple, and was developed as a seasoning that anyone can easily make delicious by combining Fundokin Soy Sauce's sweet and delicious Kyushu soy sauce with Kadoya Sesame Oil's "Pure Sesame Oil."
