The J-I was a solid rocket expendable launch vehicle from Japan. It flew only once, in 1996, in a partial configuration, to launch the demonstrator Hyflex. The vehicle never flew in the final orbital capability configuration, which should have launched the OICETS satellite (which was finally launched on Dnepr).
