Help, Kotemon conundrum!

Hello I'm new to digimon and I'm 3 hours in and missed getting Kotemon to 200% scan in the Tokyo metropolitan lobby. I saw there's another place to get Kotemon in the central tower, the thing is I'm not sure where that is in game and don't want to look anything up for fear of getting spoilers. Should I restart and farm kotemon or is the central tower area relatively soon ahead. I don't want to play most the game without kotemon. Thank you :)
