The Kouraku Kiln was founded in Arita (Saga Prefecture, Japan) in 1865 and has been producing ceramics for the past 150 years. Over that time the facility has accumulated a vast collection of pottery that has, for one reason or another, gone unsold.
The warehouse is so vast that some workers use a bicycle to get from one side to the other. And they’ll be the first to admit that even they don’t really know what’s in there.
The production facility is now inviting visitors on a “treasure hunt” to try and get rid of some of their stock.
