The Mirai isn't using a hydrogen engine, it's using fuel cells. There are also internal combustion engines that burn liquid hydrogen. Somewhat more practically it's fairly straightforward to convert existing gasoline engines to run off propane or compressed natural gas, you can get cars like this today but the refueling situation is of course not great.

CNG takes too much space and also uses higher pressure containers, while it can be easily converted to DME and stored in containers pressurized at 0.5 MPa.
