Terrorists and drugs

Ok, the post is kinda late, but I still want to dedicate a post to the Japanese immigration procedure...
Arriving at Osaka Kansai airport I had to go through customs. There were about 8 counters for Japanese and only two for foreigners. With planes arriving from Dubai, Seoul and Singapore at that time there were obviously a lot of these and the queues in front of the counters got longer and longer. Well, that gave me time to study the impressively big yellow anti-terror posters that announced a "very thorough immigration check" including fingerprints and a photo (no, you won't receive a copy). I have to give the Japanese credit, they questionned the Koreans in the queue as thoroughly as the full bearded Emiratis - an equality that I didn't see at Boston Logan airport...
After long waiting and getting anxious that I'd miss my connecting flight, it was my turn. Ok - fingers on the tab and "cheeeese" for the camera. That was the easy part. The guy questionned me about my stay in Japan - why I didn't have a return ticket from Japan, if I wanted to stay in Fukuoka the whole time, blablabla... He saw that my return flight from Sydney would be in December only, so he started doubting that I'd stay in Japan for less than 3 months (well, actually I won't). I had the bright idea to show him my 3-month Australia visa then and that made it credible that I'd leave Japan in September. (Applying for a 6-month visa right away is a hassle. It's easier to extend the 3-month visa, that's why I didn't declare the full lenght of my stay).
Then I had to go through customs with my luggage. They had dogs around, opened my luggage and fumbled through my stuff. And then the guy asked whether I had any drugs with me. I said "no" and he then said "not even marihuana". After I denied that too, he asked me another 3 (fucking) times. What the heck did they have the dogs there for?!
Well, Japan obviously thoroughly sorts out terrorists and drug dealers...
