I'm just about to go out for my daughter's Basketball match, so I'll confirm that it is the Tachikawa Ki-77. Only two made - so I thought worthy of this thread.
Was watching a fascinating documentary about the air links between the Germany/Italy and Japan during WW2, and this aircraft came up with it's attempt to fly from Japan to Europe after the Italians had flown the other way. The aircraft was lost somewhere over the Indian Ocean.
Interested to learn that the other prototype made a record endurance flight of 57+ hours and 10000 miles in 1944. This aircraft survived the war - image on Wiki in US markings - but was scrapped soon after.
Over to dook.
