The Birthplace of Naoteru and Naoharu Kataoka is the birthplace and Kataoka family residence dating back to the mid-Edo period when the family relocated to Tsuno circa 1700. Because Naojiro Kataoka built a new home during the An’ei period, this residence was inherited by Naojiro’s younger brother Naoshi (Magogoro’s grandfather).
The family patriarch at the end of the Edo period, Magogoro, was active in the same Tosa Loyalist Party as figures such as Ryoma Sakamoto and Torataro Yoshimura, and sold valuable farmlands and family assets to raise funds to support his compatriots. Magogoro made great effort for the sake of Japan, but passed away in this home before the Restoration came to pass.

Following the passing of Magogoro, the family was supported by their mother Nobuko alone. Nobuko worked at her loom until dawn by the light of just two candles while the brothers studied by her side. Once their debts were paid off, Nobuko was able to send her children to the Tosa clan school, hoping to make them into worthy individuals.

The family repurchased the land, which had temporarily fallen into other hands, with a loan of ¥380 from Takayuki Sasaki, a comrade of their father who had become the Minister of Industry. The brothers joined forces during their terms in the civil service to repay the loan to Sasaki out of their pay.

In Taisho 5 (1916), the brothers, who had gained esteem in the business world, renovated their childhood home. It was their mother’s greatest wish. They purposely did not recreate it as a grand mansion, instead renovating it with the layout that they had lived in as a family during the Edo period left intact.
