Thanks msm2000uk!
It seems not too many visiting Tokyo in July?
My dates are 13-17.07 flying AMS-HND-AMS.
That will be my third trip to Japan in 2017
I'll update the WIKI shortly.
July is the rainy season, so maybe that put people off.
I wanted to go in April and May, but couldn't find flights so instead booked for October.
