Japan procured a silk balloon from Yon in 1890 but didn't find it useful. Later they purchased a kite-balloon from Riedinger in Augsburg. They continued building their aeronautical forces and used them in the war with Russia. [2] In 1912 they reportedly bought a German airship, Parseval XIII.
Relevant early inventors, authors, managers, and pilots:
- Great early kite inventor Chuhachi Ninomiya (see en.wp) may not have gotten patents.[3][4]
- Relevant aero inventors include Captain Kumazo Hino and perhaps his co-patentee Tomijiro Komuro, who may have worked on aircraft. Hino went to Germany for training and there is a book about it.[5]
- Navy engineer Sanji Narahara contributed a propeller or propeller design.[6][7]
- Captain Yoshitoshi Tokugawa went to France for training.[6][3][8]

Peter has ordered a book on Hino's time in Germany. This book is relevant too but too expensive for the moment.
