Young kids running amok, dancing crazily, jumping on adults' backs demanding piggyback rides.
For many English teachers, these are occupational hazards. For Mike Maher-King, moments like this are the best part of his life in Japan. For the children, who are growing up in an orphanage in Fukui Prefecture, this is one of the highlights of their month.
