Oh, for the joys of Japanese takuhaibin. I discovered it on a ski trip to Japan and wonder why it isn't more universal. It's a great, low cost shipping service that works for all kinds of packages and parcels and was made so prevalent in Japan by the fact that there is very little luggage storage on the shinkansen.
I have no knowledge of this service, but at least it exists.

I wear as much bulky stuff on the plane as possible. As well, I've learned from experience that I need no regular clothes on a ski trip. Whatever I wear on the plane is my outfit for the whole week. The very casual approach to ski towns means that my jeans and ski jacket will take me anywhere I want to go.
