Regarding the customs declaration, I submitted it a couple days in advance before arriving in Japan via Visit Japan website - www.customs.go.jp/english/summary/passenger.htm I recommend doing it. It will save you a lot of time at the aiport. So in the video the last moment you can see before clearing the immigration was at 03:03 minute when I was asked to turn off my gopro camera. Then I passed through the passport control, collected my checked-in luggage and then followed my way to the customs control. Since I submitted the declaration online I had my QR code ready to use. I just followed the signage and used the QR code in one of the machines to pass the cutoms control. That part wasn't allowed to be filmed. But it's pretty easy. Just follow the signage or ask any customs stuff at the airport. They speak english so no worries. Then I left the cutoms, turned on my gopro camera and turned right. That's the moment you can see in the video - 03:20 minute. I turned right and went straight to the end of the ground floor because I was looking for the JAL ABC mobile stall. I wanted to buy specifically their SIM card cause it looked like a good value for money - unlimited data transfer for three weeks for 7k yen. After I bought the sim card and configured the APN manually I turned back and headed toward the first floor. I hope it clears things up. If not please let me know and I'll elaborate more on my way at the airport ;) PS Osaka Kansai Airport is not that big. The Istanbul Airport where I did the two hours layover was a bit more complex to navigate :D
