Hakone, Japan, nestled near Mount Fuji, is known for two things: hot springs and the Open Air Museum. The Japanese place eggs into the hot springs and they come hard-boiled and black. When eating one of these eggs, it is said that your life will be extended an extra seven years. The Open Air Museum has an extensive Picasso exhibit, devoted to his later works, including a lot of pottery. The completely outdoor exhibits are modern and often fairly interactive (an architectural playground features a series of domes to climb in and a jungle gym made solely of colorful rope) and allow the works to be seen from various viewpoints. I highly recommend it to any traveler.
