The Komatsu G40, which had the distinction of being Japan's first ever
domestically-produced bulldozer, now joins Tamiya's 1/48 Military Miniature
Collection. It was developed as a means to speed up airfield construction, which
had been done by hand up until that time. Based on other existing farm tractor
designs, it was equipped with a 50hp gasoline engine as well as a hydraulic
dozer blade. Approximately 150 were built from 1943 to the end of the war and
they were sent to engineering units in the northern and southern fronts. It also
influenced the design of postwar Japanese construction machinery.
