Only asking because if you are not so familiar with the layout then you should add padding to the schedule.
Approximately three hours in Harajuku is not a lot of time but if you have specific things you want to do, it would be worth it. If it is to just look around, it would feel really really rushed. You would have to do a cost benefit comparision.
So I flew in to NRT last week and arrived at 2 PM, it was a ghost town at terminal 1 ! Was on a bus for Shibuya by 2:40, and home by 4PM in Harajuku.
