To come to Hekou Lake, we must take a cable car to the mountain to see the best place of Mount Fuji. But the weather is very important. We can travel freely and have plenty of time. So we stayed on the mountain for more than six hours. When the clouds left, we could see Mount Fuji. Fortunately, we took some intermittent photos when we came in the morning. We waited for a day without waiting for all Mount Fuji. Sometimes it was cloudy and we could see the mountains clearly, as long as the clouds left. Clouds are not thick enough, but they are still very fruitful. From 9 a.m. to 5 p.m. cable car time, 80O yen for each adult. It's worth coming!
