Which led me to read some stuff about the company! And found an interesting paragraph from an article at Sega-16:
Together with his brother Yoichi, Miyaji founded Game Arts in 1985 after graduating from Fukoaka High School in Saitama Prefecture, a bold move for someone who was only 19 years-old. Miyaji stated that he had started Game Arts with the intention of producing more than just gaming software, saying he wanted to prove to the world that games could indeed be art, and he focused all his energy into developing titles that realized this ambitious goal. With few resources and even less money, the siblings began programming games for computers.
