Fourteen luxury cars, including eight Ferraris, one Lamborghini, a Nissan GT-R and a, er, Prius, all tangled together on the Chugoku Expressway in Yamaguchi Prefecture.
Ten people were taken to hospital, but spare a thought for the insurers - the damage bill could tot up to more than $3 million.
That makes it more expensive than this Monaco bingle involving a blonde, but probably not as funny.
The crash happened on a curve and involved an oncoming car - a Mercedes Benz.
Japanese daily Asahi Shimbun reports that one of the Ferraris hit a median strip. It hit the Benz and as it disintegrated the next 400m, following supercars from an enthusiasts' club piled into the wreckage.
Read this and weep: Among the casualities were two Ferrari F430s, two Ferrari F355s, two Ferrari 360 Modenas and a Lamborghini Diablo.
