Aito Net is a car dealer and workshop which has two locations, one in Amagasaki and the other in Itami, Hyogo prefecture.
Today we are looking at the Amagasaki location. There are various (mainly Nissan) cars for sale which have been extensively modified for drifting. It was closed at the time however it's easy to see that these cars are quite heavily modified and not for street driving.
