Saitama shares a border with Tokyo to the north and is home to a large amount of people who work and commute to Tokyo each day. Saitma is mostly suburban with the outer areas more sparsely populated and rural. At the very edge of Saitama where the mountains start is a popular place for white water rafting. Saitama also has a large stadium that houses professional baseball/soccer along with many famous concerts who come to "Tokyo".
