I can absolutely see the appeal of not wanting to make extra changes to or from a metro line and having the hotel very close to Tokyo station.
Ski equipment and large luggage? This is Japan. The intelligent thing to do would be to use a service like Yamato Takyubin to transport those things. Send skis and equipment directly to the place they will be used and then back to the airport to be picked up on day of departure, do not carry them at all through mass transportation in Tokyo or elsewhere in Japan.
