The foundation of industrial modernization of Japan was established in the latter half of the Meiji era. Industrial revolution progressed at a rapid rate during the following years, but products made domestically were still inferior compared to its western counterparts. To overcome this situation, the leaders of Japan saw the need to produce more industrial machinery domestically to promote advancement in techonogy. In this effort to grow as a country, a great need for prime movers (motors) arose.

It was under these circumstances that the HATSUDOKI MANUFACTURING Co., LTD (HATSUDOKI=engine) was founded in March 1, 1907 in Osaka, Japan.The company engaged exclusively in the manufacture of suction gas engines for the next 15 years.

Although the world economy was in depression, the demand created from the World War kept the industrial modernization on track. Engines got bigger and more powerful, and at the same time demand for compact engines from small businesses grew as modernization took place.

To take advantage of this growing demand, our first compact engine was manufactured with technical cooperation from R. M. Bit Corporation based in Chicago. With its unconventional fuel injection system, the engine became a big success, earning reputation for its simplicity and ease of operation.

By this time, there were numerous other companies that were producing Diesel engines. To identify engines made by HATSUDOKI MANUFACUTURING CO., LTD., our customers started to refer to our engine with the nickname DAIHATSU" (DAI=Osaka, HATSU=engine).

During this time, the company expanded its product range and started the manufacture of vehicles amongst other products. Since the company was now manufacturing products other than engines, the name HATSUDOKI MANUFACTURING CO., LTD. was changed to DAIHATSU MOTOR CO., LTD. on 19th DECEMBER 1951.

The because of its old facilities, the Osaka factory became inadequate to meet the need for increased production. Also, a dense metropolis like Osaka was becoming an inappropriate place for a factory to operate. It was therefore decided to move the factory to a new location.

That location was Moriyama city in Shiga prefecture. The project for construction of this new factory was advanced under three mottoes: "A modern factory capable of high quality and high productivity", "A model factory for the environmentally conscious", and "To care for the local society and community". The construction work for Moriyama No.1 factory commenced on November 1969, and was completed on July 1977. This was followed by Moriyama No.2 factory, which started operation after it was completed in 1979.

1996 May Celebration of the 30th Anniversary of the Founding Our Company

This company has experienced a variety of the vicissitudes since its separation of and independence from Daihatsu Motor Co., Ltd. in 1966.

Over the initial decade, the company's foundation was formed, during which we could enjoy favorable development, but thereafter we were afflicted with continuous hardships, undergoing the low growth age resulting from the Oil Shocks, and in 1966 the raid of marine and shipbuilding slumps and abrupt change to high yen exchange rates have undermined our growth.

From 1990 to the present, the management of our company was finally driven onto the route of recovering the financial balance to the black through renovation of company constitution, thereby working its way to resumption of the dividends. Then the company has at last become able to ride on a basic recovery wagon, and could celebrate the 30th anniversary of the foundation of our company in May, 1996.
