Haneda introduced me to a new airline.  Air Do.  They had a lot of traffic coming through Haneda, both narrowbody and widebody.  In fact, one of their 767s took off in great light as I was walking to the viewing terrace which was a touch frustrating.  It was a long time before another one took off but at least the evening light improved so the wait was worthwhile.  Meanwhile, the 737s were busy and some 767s taxied past after landing so I got to see a few of them in action.
