Oguchi joined Sega in 1984[7] and was tasked to develop a game about penguins as they were popular in Japan at that time.
He also directed several arcade video games with Super Monaco GP, Heavyweight Champ and Rad Mobile.
Oguchi stated that the culture at AM3 was that he would not reject or interfere with ideas, although he would make suggestions.
He also played a crucial role in allowing Segagaga to continue development which was initially taken as a joke by other Sega management.
[11] Oguchi was promoted in 2003 alongside Yuji Naka and Toshihiro Nagoshi, based on the success of arcade games that used cards and medals.
