It was a late flight arriving in Tokyo early morning.
The aircraft was a new A350 which was a pleasant aircraft to travel in, more leg room, slightly wider seats and the windows are adjustable to allow light in at your requirement (even in the toilets).
The staff were very pleasant, food reasonable and service reasonably good. What made the flight more pleasant was the efficiency of the Haneda airport. From landing at 7 am to waiting for the bus to head to the hotel was only 25 mins.
All in an pleasant experience.
