Actually the last day was a bit of a lost day... I'm not sure if it was tiredness or the feeling of loss that that the end had come. We didn't really have the energy to do much, and our base around Shinagawa didn't have that much to do.
That and the weather turned against us. The train ride out to Narita was slow, dark, and cold... the faint snow falling over sodden fields a stark goodbye gift from Japan.
