One April a couple of years ago, I flew sat-iah-nrt and back twice. Our daughter was living in Yokosuka and due to deliver our grandson. My wife wanted to be there for the big occasion. She had four weeks vacation, and I didn't have any. I voluntered to fly over with her, fly back home, and return in four weeks to fly back to the States with her. It worked out great. We got there on a Friday, our daughter took us to see Kamakura on Saturday, I left on Sunday, and she went into labor and delivered on Monday.
