In 1927 Osaka Mainichi Shimbun purchased a sample, the 11th aircraft of the newspaper, and received the civilian register J-BACC. It was employed as a communications aircraft until 1937.
On April 27, 1928, pilot Haneta Fumio loaded the plane with enough gasoline for a 20h flight and took off from Kakamigahara airfield, Gifu Prefecture, at 05:02. He flew in an eastern direction, over Hamamatsu, Hakone, Tokorozawa, Sendai, then turned south, Tokyo, Shizuoka, Osaka, then continued until Takamatsu, and finally returned to Osaka where he landed at the Army parade grounds, at 18:25. He flew for 13h23min, a distance of 2,100km, a record flight. He wanted to fly for more and had enough fuel, but at that time night landings were extremely dangerous. So, basically he flew from early in the morning until darkness fell.
Here's a close-up on the tail marking.
Below are two photos from Model Art 420 and Nihon Koku-shi, showing the Ryan in its later overall scheme, which was, purpotedly, brown around the cowling with light blue fuselage.
