The exact date when Hayashi founded his factory is unclear. Mori Chiyomatsu, a student at the Tokyo School of Commerce, reported in 1902 that Hayashi began manufacturing pendulum clocks in April 1884.  However, according to Hayashi's biography, he began production in 1882, while a history of Nagoya dates the beginning of production in 1887.  Part of this confusion is over who is the first, whether it was Hayashi, himself, or Chujo Yujiro.\footnote{Uchida Hoshimi,   \textit{To~kei ko~jo~ no hattatsu} (Tokyo: Hattori Seiko, 1985), pp.   216-23. 



Jiseisha    Jiseisha: Hayashi Ichibei

Hayashi had a long history with clocks.  He is descendant of a merchant family which sold \textit{wadokei} during the Tokugawa period and after the Meiji ishin, Hayashi sold western clocks obtained from traders in the treaty ports.  By 1870 he had established direct ties to manufacturers in the United States and during the 1880s he tried to develop the machinery to manufacture his own clocks.  According to Hayashi, in 1882 he successfully developed a pinion lathe the last machine necessary for producing the clock mechanism.  Other accounts however, suggest that Chujo manufactured two clocks, and took them to Hayashi who agreed to sell them.  Then, in 1887, Hayashi bought the manufacturing rights from Chujo and opened Jiseisha.
