I've booked to go for my first Japan ski trip in the first week of March next year. We're off to Hakuba and will be staying at Hotel De Laile, right next to the Sakka lifts. All of my skiing so far has been in NZ conditions in July and August, so not overly cold (I have a habit of being there the week before snow falls). I tend to be relatively toasty at the base of Cardrona, then get a bit chilly at the top after the lift up. However, my concern is that my current ski clothes won't cut it for Japan. What is the general consensus on types of clothes that are required? Will I need full under-thermals and insulated jacket and pants, or will my NZ experience be a fair indication for what I'll need to be wearing in Hakuba? Thanking all in advance.
