The Japan pavilion was captivating. Chiharu Shiota's installation The Key in the Hand was ambitious in its execution - the entire room was enmeshed with keys and yarn hanging from the ceiling over and around 2 boats. There were also 2 videos of small children talking about their earl memories. The keys represented the passing on of links and memories across time. They had been gathered by the artist from around the world. This installation won the 'wow factor' ward in my opinion.
