Operational history

Gondola of the airship

Drawing from Taschenbuch der Luftflotten (1915)

Airship was named Walserwald and in June 1912 imported from German Empire to Japan. After the accident on March 28 1913, which damaged the ship, Walserwald was a repaired and modified in Tokorozawa depot. In 1913 ship was also renamed Yuhi, which means Flyer. Works were finished in August 1914 and Yuhi was commissioned by the Japanese military in April 1915.

On January 22, 1916 (Taisho 5), Yuhi made a test flight from Tokorozawa to Osaka. After the flight 11 hours and 34 minutes long ship safely landed near the town of Toyohashi. The return flight to Tokorozawa was not proceeded due to engine problems, so the aircraft was disassembled and transported by land. Ship was put out of service in July 1917.

To commemorate the first flight, January 22 is now known as "Airship Day." In Tokorozawa City, where the machine was repaired and reconstructed, a special baked confectionery called Yuhi-yaki is sold in commemoration of the flight.
