Every home should have one - Lockheed F-104J Starfighter 46-8594 (c/n 3094) sits atop a house in Osazawa village in Yamanashi Prefecture. Attempts were made to contact the owner of the house, but sadly there was no reply. Perhaps the owner is a former JASDF pilot?
Two F-104s are located at a cafe near Hamamatsu Air Park in Shizuoka Prefecture, despite the cafe having apparently closed; they are just visible in the background here. To get a bird’s-eye view of the Yamanashi F-104 on Google Earth, enter the coordinates 35.440677, 138.415961 in the “Search”panel.
