40kg is 88lbs that's a serious amount of luggage, to bring in. I'd like to think they'd always catch something over the top like this but not sure. Not sure why he was so brazen either. Kinda hard to hide such an amount among other things. Japan is not a country you want to be caught smuggling drugs either. I suppose he could have simply not known what was in it and paid to bring it but that is not smart either. You can pretty much guess it is not something legal inside.
