Toshiaki is the founder and CEO of Power Brain Corporation, a preparatory school and extra curricular center operator headquartered in Fukushima. He is also known as an education consultant with expertise in entrepreneurship education. Prior to establishing the company in 1998, he worked for a couple of companies, including a foreign life insurance corporation.

Toshiaki learned from his teenage experience that education is not a given. As his father's business failure temporarily prevented him from going to school, he realized the importance of learning how to learn as well as of having relentless curiosity. Years later, he found the value of having fun while learning through Mind Maps. His students are proving the effectiveness of Mind Mapping, learning well while having fun.

During free time, Toshiaki (aka an excellent chef) enjoys cooking.
