I think the lifts are actually closer to 600m. They are still very short courses and it can be frustrating because you spend a lot more time on the lifts than on the slopes. Fairly easy slopes good for beginners. It looked like there was another more difficult lift that wasn't running because of lack of business(?).

1st time to Joetsu kokusai and I was not disappointed. Large resort with quite a lot of different options to choose from, some kickers of different sizes if thats your thing (half pipe not available yet) wide runs and amazing views.
