Monkey Island, or Sarushima in Japanese, is just off the coast of Yokosuka and is a lovely day trip away from the city. Head to Mikasa Park and then look for the ferry terminal. You buy your tickets at the ticket office right at the entrance to where you board the ferry. For adults the cost is 1,200 JPY and for children it's 600 JPY.
