The powerplant selected was the 8.34 kN (1,870 lbf) thrust Ishikawajima Ne-30, then under development. However, before a single example could be built, both the Ne-30 project and the Tenga were cancelled due to technical difficulties with the turbojet design.
With some exceptions for rockets, jets and repurposed aircraft, names chosen were for: 1. Winds, 2. Lightning, 3. Nighttime lights, 4. Mountains, 5. Stars/constellations, 6. Seas, 7. Clouds, 8. Plants, 9. Skies, 10. Landscapes, and 11. Flowers. Published translations disagree, and many are simplified, especially for plants, where the Japanese referred to a specific variety and the common translations only to the broader type.
