In 1959, Hara requested through diplomatic channels return of a family sword belonging to 85-year-old Ryūtarō Takahashi, president of the six-million-member Bereaved Families Association. The sword was one of the great blades forged in Bizen Province in the 15th century. It had been carried by Ryūtarō's son, Hikoya Takahashi. Hikoya had asked Hara to care for the sword while he was assigned to a minesweeping assignment he did not survive. Hara revealed that the sword carefully preserved in the Naval Academy Museum was Takahashi's sword, and the Hara family sword which should have been in the museum was in the possession of Admiral Durgin. Retired Admiral Durgin drove to the museum to correct the error, and the Bizen sword was delivered to the old man who had lost his son.
