Leaving Japan, leaving Asia

I'm about to leave Japan, tomorrow morning I'll be in Sydney. It's only just hit me what a culture change this is going to be.
I'm sad to leave Japan, I absoutely love it and could see myself returning. It's a crazy place, in some ways its the most different to the UK, when you'd expect it to be the most western. Looking back, it's been a very diverse few weeks. I've gone from Bladerunner inner city, urban sprawls in Tokyo and Osaka to the peace and beauty of Kyoto and Hiroshima. I've been ambushed by deer in Miyajima and when walking in the mountains near Kobe came face to face with a wild boar, which was unnerving, I scarpered before it had the chance to gore.
The Japanese are so funny, relentlessly polite and helpful. If you are lost they insist on walking to where you're trying to get, rather than just pointing in the general direction, and if they don't know they ask someone else who also walks with you. At one point, in Osaka, there was four of us wondering around trying to find a bus stop. The Manga comic book culture is also strange. They're not just for kids, everyone reads them, to be honest I think they are more prevalent than normal books. Anyway, I've got to leave in about 40 minutes so next time we speak I'll be in the Southern Hemisphere!
