As pretty much everyone on here knows, he composed half of the Sonic CD JP soundtrack and IMO wrote some of the best tracks on there (Collision Chaos present, Wacky Workbench past, etc.). Yet there is so little information available on the guy. Aside from Sonic CD, it looks he did some odds and ends for Sega until about 2001, and then stopped composing for video games entirely. I haven't been able to find anything on him - I've searched Twitter, Facebook, Google, SonicRetro, even some Japanese search engines. Even the Sonic CD vinyl liner notes don't mention Ogata at all, with Naofumi Hataya doing all the writing. Does anyone know what he's been up to in the past 20 years? It would be amazing if we could eventually get an interview out of him.
