Aichi Kokuki

Aichi Kokuki KK (愛知航空機株式会社) was a Japanese aerospace manufacturer which produced several designs for the Imperial Japanese Navy. After the war, the company was reorganized as Aichi Machine Industry Co., Ltd (愛知機械工業) where they made small kei cars until 1966 when they were integrated into Nissan and developed the Nissan Sunny and Nissan Vanette.

Aichi Watch and Electric Manufacturing
The company was established in 1898 in Nagoya as Aichi Tokei Denki Seizo Kabushiki Kaisha (Aichi Watch and Electric Manufacturing Co., Ltd.). Aircraft production started in 1920, and the company relied initially on technical assistance from Heinkel, which influenced some of their designs. Later, with the prodding and support of the Imperial Japanese Navy, the company started making seaplanes using technology imported from Short Brothers in the UK.

During the inter-war period, Aichi was the beneficiary of technology transferred from Heinkel of Germany. At the time, a team from the League of Nations occasionally visited German aircraft manufacturers to monitor the ban on military aircraft research and production. A Japanese military attache who was a member of the monitoring team, let Heinkel know, confidentially and in advance, of the planned visits. Heinkel thus succeeded in continuing its design on the aircraft ordered by Aichi Aircraft without being spotted.

In 1943 the aircraft division was spun off as Aichi Kokuki Kabushiki Kaisha (Aichi Aircraft Co., Ltd.).
