History of Our Firm

Takeo Kajitani The origin of Kajitani Law Offices is traced back to the 'Horie Law Office,' established in 1920 by the late Senichiro Horie, Esq., (b.1876 - d.1939; 1907 graduate of the University of Michigan Law School, J.D., President of the Daiichi Tokyo Bar Association). In 1923, Horie Law Office relocated to the newly opened Marunouchi Building (the former 'Maru Biru.'), after which Horie, upon his death in 1939, willed the office to the late Takeo Kajitani (b. 1908 - d. 1971, President of the Daiichi Tokyo Bar Association 1969 and Vice President of the Japan Federation of Bar Associations 1969). When Takeo Kajitani passed away in 1971, his eldest son, Gen Kajitani (President of the Daiichi Tokyo Bar Association and Vice President of the Japan Federation of Bar Associations1993-1994, Justice of the Supreme Court of Japan 1999-2005), took over office.

Following Go Kajitanifs appointment as President of the Japan Legal Support Center, Masaaki Oka (President of the Daiichi Tokyo Bar Association and Vice President of the Japan Federation of Bar Associations 2015-2016) became head of the firm in April 2012.
