Using the Japan Rail Pass

Hello: My wife and I will be spending two weeks (14 days) in Japan. We plan to spend the first 7 days in Tokyo and then travel to Osaka for 5 days. When staying in Osaka we plan to also travel to Kyoto and Nara. After 5 days in Osaka we plan to travel back to Tokyo for 1 day before leaving to return home. Would a one week Japan Rail Pass starting when we travel to Osaka be our best option? Thank you.
