This is one of the heirs of Nakajima, an important aeronautical construction company of WWII.

-Omiya-Fuji Kogyo Kabushiki Kaisha, made the JO-1 axial flow turbojet destined for an aircraft of the Armed Forces of Defense.

-The JO-1 has an 8-stage compressor, eight combustion chambers and a single turbine. It delivered 2205 lbs of thrust at 12,000 rpm.

From Appendix A4/6: The JO-1 turbojet engine mentioned in the main text may clearly be a development of the Ne-20 but Americanized, in the style of the J-35 and J-47, with visible separate combustion chambers.
