Everything about the Tokyo Marathon 2015 was amazing.
The whole city stops and comes to help out for the face which is truly spectacular!

The organisation of the event, the volunteers, the scenery, the whole thing was amazing, start to finish.

the only things I learnt was I can trust event organisers to bring my bag to the end of the race more than my wife, ha ha, (she forgot it and I had to ride back to the hotel in the cold!)
and, at 29kms, when I had no choice to make a toilet stop, and there was only eastern style toilets, and I had to learn very quickly how to use it!

aside from that though, an amazing event I would recommend to anyone!
