He is fluent in Japanese. I believe he may have been added to EPD Kyoto as a Planner or Coordinator.

Nitta worked at Nintendo for 23 years mainly as a programmer in EPD's technology department before leaving to become an independent mobile developer for a game titled Cave Explorer.

"Sugiyama: No, I worked on a lot of the very first Famicom games. I joined Nintendo the same year as Yoshio Sakamoto."

What we know

• SimCity (1991) - Co-Director
• Pilotwings (1990) - Director
• Super Mario Bros. 2 USA (1988) - CG Designer
• Yume Kōjō: Doki Doki Panic (1987) - CG Designer
• Zelda II: Adventure of Link (1987) - Co-Director
• Ice Climber (1985) - CG Designer
• Clu Clu Land (1984) - CG Designer
• Pinball (1984) - CG Designer
• Baseball (1983) - CG Designer

This means he joined Nintendo in 1982 (instead of what we originally calculated in 1983). Besides his admission on working on "a lot of the very first Famicom games" he also probably worked on some arcade or game&watch titles since Famicom development didn't begin until 1983.
