The Hakone Open-Air Museum is a must visit when you are in the area. This is the first Open Air Museum, an outdoor sculpture place with artists from all over the world. They offered a large collection with a building dedicated to Picasso. The location was simply beautiful and the museum spreads across a stunning landscape that added so much more peacefulness, spirituality and sophistication to this place. You will find both classic and modern sculptures. You will have a lot of great photos opportunities across the park. This is also a great place for kids. You will need at least two hours to walk around.
