Company background

The Institute traces its origins to 1971, when Tomoo Kinoshita began researching his own family’s ancestry. For many years, alongside his work, he went on to trace the ancestors of the families connected to the Kinoshita family, helped by his daughter Keiko and his grandson Yuya, now the Institute’s president. It has been a life’s work across three generations.

Around 2000, I began assisting my maternal grandfather, Tomoo Kinoshita, with our ancestral research.
As part of the business of the family mutual aid corporation I represent, I began full-scale ancestral research in March 2015. With a policy of searching for all direct ancestors regardless of surname or lineage, I discovered thousands of ancestors (5000 over) within a few months, primarily through my father’s family, the Aizu Tomida clan, who married into Kinoshita.
