I was caught my foot from the beginning again after an interval of 2 years at Haneda Airport. Last time in 2019 I lost my medicine in Narita airport before departure.Stupidly enough, 30 minutes before the departure from Haneda airport Japan, I had lost my smartphone in the vicinity of the drop luggage point. I recognized the loss in the lounge when I checked E-mail from my PC. I sent an E-mail to my son and asked him to ring my phone. Luckily somebody noticed it. I could retrieve it at the lost and found counter.
