The Japan Federation of Landscape Contractors organizes an annual landscaping contest, where landscaping contractors from around Japan arrive on site with their mini pickup trucks and then spending several hours transforming the cargo bed into a small garden. The contest is called “the Kei Truck Garden Contest.”

The Kei Truck, or kei-tora, is a mini truck of Japanese origin but is now used widely throughout Asia and other parts of the world as well. In Asia, these trucks are mostly used in agriculture, fisheries, and construction as they can be maneuvered easily through small streets. Some models have also appeared in the US for off-road use typically by farmers and hunters.
