Do not fucking do this. Only take the bullet train to your destination if you are skiing on the main island of Honshu - such as Myoko Kogen, Nozawa Onsen, Zao Onsen.
If you take the Bullet Train to Hokkaido, it will take you 8+ hours to get from Tokyo airport to Sapporo because the Shinkansen only goes as far as Hakodate.You will need to take a 3 hour express train from there that is a lot slower and you will have wasted a whole day (unless of course you are a foamer who loves being on trains - which, fair enough). Additionally, you cannot take as much baggage on the shinkansen - so you will possibly have to ship it to your destination depending on how much you have.
Instead, either fly direct to Sapporo from wherever you are, or Fly to Sapporo from Tokyo. Instead of an 8 hour train, it will be a very short flight.
Also, if you ever need to ship anything within Japan, it's super fucking cheap to do it (like, a 50lb bag costs like 15 bucks to ship almost anywhere) so take advantage of this if you plan on travelling somewhere but dont need your skis for a day or two. (I always use
Kuroneko aka Yamato Transport. You can ship things from any 711 store (I'm not even kidding)
