Packing for Backpacking

This post is to test if the "update blog by e-mail" option actually works. It's also a last ditch attempt to delay troublesome packing.

I'll explain the problem- My first port of call is Japan. I'm spending a month in a student dorm in Tokyo, heading out every day to study Japanese at the Shibuya ARC Academy. While in Japan, it will be useful to have a selection of nice clothes so the cleanliness conscious Japanese won't view me as a dirty Gaijin hippy.

However, in Cambodia conditions are totally different. Jumping from guesthouse to guesthouse almost daily, I'll need light luggage that can be carried on my back without snapping limbs. This must include such necessities as a mosquito net, insect spray, medical kit, syringes for blood transfusions, a water bottle, sun hat, sixty days of anti-malarials, water purification tablets, elephant gun and the ever-handy-in-hot-climates Johnson's Baby Powder.

How on earth do I pack smart clothes for chilly weather, Japanese dictionaries + guide books and still have room for everything else without creating a load so heavy I need a pack horse?

And while on the subject, how much do pack horses cost these days?
