Travel in Kochi

My American friend and I went to Kochi Prefecture over the weekend to visit. We stayed at his friend's house. His friend and his wife were also American, so I am the only Japanese person in the group. He kindly took us many places in Kochi such as a crave, beaches, a castle, restaurants, and a shopping arcade. His house was at a very country side, but we enjoyed walking and seeing beautiful nature from the hill. I learned that you can find something fun regardless the place where you are. I really appreciate their help. It was a very meaningful weekend.
