Before merging them into JAXA in 2003, Japan had two aerospace agencies: NASDA and NAL, which wanted to collaborate with the USA on the International Space Station when it was proposed in the 1980s as "Space Station Freedom". Eventually, the ISS got the JAXA Kibo module, but another part of the proposal never went into production. NASDA designed the unmanned HOPE spaceplane to be capable of launching on an H-II rocket, supplying the ISS, and then landing on a runway. Kawasaki built a 1/4 scale wind tunnel test model of the HOPE-X prototype, which never got into orbit by the time Japan cancelled the project during its 2003 space budget cuts. Fortunately, the wind tunnel model was preserved, and I saw it while visiting the Kakamigahara Aerospace Science Museum (Gifu Prefecture) in January 2015. It reminds me of the X-20 Dyna-Soar, but with a less pointy nose.
