The driver is Motoharu “gan-san” Kurosawa who is a regular on Best motoring. Motoharu Kurosawa has a long racing career, but most of his career he was a factory driver for Nissan and Honda. So of course he raced the Hakosuka during its glory years!
In this second video he’s clearly doing a show run for television, so he’s not going flat out. Also note that the road of Fuji Speedway used to be much bumpier than nowadays!
