This photo was taken at the start of the day, just as the public was starting to come in.
The building at the right houses the floral trade section. The ginormous warehouse on the left is all the bonsai activity, with a tiny section for ornamental plant sales. Inside, this building was divided into 4 corridors for bonsai display, a large room for suiseki, the auditorium for New Talent / workshops, a cafeteria and a large section for bonsai traders. Plus a couple of break-out rooms for EBA meetings and smaller talks.
Looks like someone brokered a really, really good deal.
