Narita Airport T1–>T2 late evening transit

Hi people, my flight lands in Narita airport, terminal 1 at 11 pm, and I need to get to terminal 2. I understand that I cannot walk to the terminal, and there should be a free shuttle bus service. However, I'm not sure it operates late at night. Does anyone know its operating hours, and, alternatively, can suggested me a way to get to T2?
