Well we love Kawaguchiko and Kanazawa.
Kawaguchiko we have stayed in the hotel Regina Kawaguchiko and you have excellent views especially from the top floor. Twin beds only in the western rooms but the top floor has it's own little Japanese bath with a showering space beside it. The problem though is you can only book it 6 months out so now to mid December. So we have a back up plan for the Fuji View hotel which reviews say views of Mt. Fuji from the room. Both of these go for ~ $A4-500 a night. There are a couple of hotels on the other side of the lake where thpictures show absolutely fantastic views of the lake and Mt. fuji. but they go for 2-3 times the price.
Lots more to do around the area. Flower farms,orchards and the Maglev test centre. unfortunately you have to be Japanese to go on a test run.
The Yamanashi Prefectural Maglev Exhibition Center showcases maglev technology—magnetic levitation—and introduces the Chuo Shinkansen, or Linear series trains, which will connect Tokyo and Nagoya by 2027.
