I got my TTP yesterday in Haneda Airport Terminal 3 and it took about 100 Minutes for them to complete the process. The agent and her supervisor who kept coming and going back from the kiosk to the office were pulling out and scrutinizing manuals left and right.
I arrived at immigration with 2.5 hours before boarding and after getting the card , literally got 5 minutes in the JAL Sakura lounge for a very late breakfast then onto the plane.
Hopefully I was the guinea pig for them and whoever now goes for the secondary interview doesn't take anywhere near as long. Maybe the staff who normally handle TTP were not there, who knows.
Anyone doing the secondary interview soon at Haneda, maybe add some more time if you can spare it. My first TTP was done in Narita years back before Covid and it certainly didnt take anywhere near this long. Maybe 30-40 minutes if I remember right.
I still appreciated the effort of the staff to get the job done.
