とらんすふぁ (TransFur, the "animal transformation event",) was the sole furry convention in Japan from 2005 to 2007. Held in the city of Kawasaki since 2005, the event aspired to cover the full spectrum of furry activities.
A new instance of the event was not scheduled after the fifth iteration. Most of the main organizers instead launched a successor event, Kemocon, beginning in 2008.
