3 more days to Japan

Packing issues
I wonder if I should..

(1) ..bring the waterproof jackets, unlike the time I went Australia, severly underpacked.

When Pa called me up in Sydney asking me why I was sounding so breathless over the phone, I told him I was running back to the hostel as it's too bloody cold to be walking slowly. Totally regretted not bringing the ugly Aigle parkas (Gore-tex! Wind/Waterproof!) at home as I chose style over practicality. Ended up at the North Face store next to the hostel and buying overpriced fleece jumpers..

(2) ..not bring so much, as I totally intend to take over Tokyo buy quite a bit. The weather doesn't seem too harsh..21C/16C. The problem is, I don't quite remember how cold is the mid-10s and my cold tolerance seem to have gone down considerably eversince I started practising Bikram Yoga o.O

I hate packing, and all the Samsonites are either spoilt or being taken. I don't think it's a good idea to be messing around with a clumsy luggage when I take the subway as well..so I guess I'll settle with a backpack? Changed my JPY currency already, now I'm starting to feel the impact of all these travelling. Just bought for the ticket to Amritsar (hehe!) for $800+ yesterday. I'm a big spender!

The outdoors
I can't wait to go trekking! I hope the weather gets colder in Japan so the snakes will be hibernating. *paranoid* Kyoto is starting to bore me, probably because I've been reading up too much on it. Maybe I'll take a trip to the outskirts (and not get lost). I don't have hiking shoes though. Argh, totally forgot about it! Sports shoes will do, I hope? =/ I'm a wannabe-trekker, not so hardcore like duck though. My brothers are still not convinced I like doing this! Idiots.

Will only spend time in Tokyo for the last few days, and staying in slightly better accomodation where I no longer need to share the room with strangers.

Should I bring the laptop? But it's so heavy..
