On a previous visit to Haneda I ended up getting a photo of a Japanese Coast Guard Gulfstream.  This time, the weather was not great so I ended up staying on the side which should be backlit but wasn’t since there wasn’t much light!  A turboprop showed up on approach which I hadn’t noticed online and initially wasn’t bothered about.  However, I shot it and it turned out to be a Japanese Coast Guard Dash 8.  I was pretty pleased!
