The Via Inn Kanazawa is literally about 20m to your left when exit the Shinkansen gate. It is in the station and you just have to go up to the third floor for the Hotel lobby. The rooms are small (typical in Japan) but very clean. Contains a fridge and a couple of hanging pegs. Note that almost everything is written in Japanese and the staff know only a small amount of English (my Japanese is even less). Very handy to get the free JR bus that takes you to the Kanazawa Castle, Kenroku-en Garden, Omicho Market and others.

Can't fault this hotel, if I'd paid attention to the reviews I would have known it was right inside the station (I went out of the exits looking) but it really is around the middle of the station through a set of automatic sliding doors. You don't have to go outside at all.

Room clean, although compact (limited room for luggage, but these appears common for many hotels in Japan). Good value for what you get, you wouldn't know you were in a station.

Quite enjoyed getting breakfast in the German bakery near the Tourist Information, excellent value, and plenty of other choices within the station, especially during the day. There are also places outside of the station such as traditional izakayas if you hare happy to have a wander about. It is quite a way from the popular tourist areas (about 30 to 40 minute walk) and much of the walk is a bit boring along main roads. Felt very safe walking at night though.

Real bonus is not having to carry your luggage a long way from the station!

Convenient for car hire if you want one, we used Nippon just next to the station for a trip to Takayama and surrounds to explore the countryside.

If you are travelling in Japan by public transport, this is a superb hotel choice.
It is right within the impressive Kanazawa station with its private entrance. The lobby is on level 3 and the rooms are on floors above. Quiet, clean and nice. You won't feel the business of the station below you.
Great access to many restaurants and shops within the station, also the shipping mall Forus.
You won't miss the train or bus.
