Corrected entry: There is a scene, after the building is taken, where Hans gathers the hostages and asks which one of them is Tagaki. The would-be heist is obviously well-planned, well-financed, and well-scouted. He has no idea (through photos or surviellance) of what Tagaki looks like? Seems unlikely.

Correction: Hans is playing a mind game (and probably also trying to get a 'feel' for the people in the room). He knows who Takagi is; he finishes his little speech right in front of him and is looking at him when he does so. He just wants to impress upon the witnesses that he knows a LOT about Takagi, and potentially them if they get in his way. He also is trying to find the weak links in the group - who's willing to sell out the boss.
