Daichi Sakamoto started cooking at age five, helping his mother prepare bentos for his father, younger sister, and himself. Chashu was never a missing component. Mother Sakamoto had learned how to make it when she studied abroad in Hong Kong. It was young Chef Sakamoto who mixed the marinade, a formula he perfected as he grew into his teens.

Many years later, he apprenticed under famed Chef Kazue Inoue at a luxury ryokan in the Nagano prefecture. There, he studied the art of kaiseki for seven years, and took a particular shine to the futamono and tome-wan soup-based dishes. His calling was starting to simmer.
