Not too much can be said about Tochisaurus because so far it is only known from a couple of foot bones, However these bones do seem to be most similar to those seen in troodontid dinosaurs. Additionally with lengths of about twenty-four and twenty-two centimetres long, the foot bones of Tochisaurus do indicate that the genus would have been towards the larger end of the size spectrum from known troodontid dinosaurs.
