Yamanakako has a more modern feel than Kawaguchiko in general.
We were able to appreciate the beauty of Mt. Fuji at 5am from our room, and it was wonderful!
When you go out of the hotel, just across is the lake, which is a very refreshing sight!
For the food, it was not bad, but we have had better Japanese meals. So if you have tried Kaiseki already in the past, but do not really like it, it is alright not to get a meal plan, because there are a lot of restaurants nearby!
The service is great!
