Meluchja thank you sooooooo much for your response

You've certainly put my mind at ease about the nappies. Food will be interesting though. ATM I've got about 4 days worth and it weighs about 4kgs! The other option I may have is doing a bit of cooking if I can get my hands on some fruit and veges. I think we're going to have access to a kitchen for a while so that may be my best option.

We're having a couple of days in Tokyo and then we're going to Hakuba to ski at Hapoone for 6 days. After that we're headed to Kyoto for a few days before heading back to Tokyo to fly home. Any suggestions of what we shouldn't miss in these spots?

Thanks for the advice on the baby Panadol etc. We're all fitted out with warm gear and ski stuff - incl DS (he looks so cute!)

Thanks again for all the advice - much appreciated
