Indeed! The Kawasaki Asuka, based on C1. QSTOL test bed as tipped above. The next tip would've been that besides the runway length restrictions the designers were concerned of noise abatement. If one uses QSTOL as a search word in ones favourite search engine, the Asuka is the first to come up in pictures.
One strange looking ac with those big nacelles above wing.
Your call, sir Asturias!
