As your request stands, the only information we'll be able to give you is that which he would discover upon searching the company's webpage, wikipedia, etc.  While we can provide this information, if you'd like for Adachi to dig deeper, we'll need a better idea as to what specifically he's looking for, and what skillset he's applying to it!  I.e. is he searching online, is he conducting interviews with employees, how skilled is he as a detective, etc.?

If the answer to that is that he's only doing non-disruptive research online, as we said, we can give you the information that is available to any characters who care to look into it, but we'd like to give you as complete an answer as possible to satisfy what you're asking for.
