From The Fighting Bunch, by Chris DeRose (St. Martin's, 2020), Kindle pp. 291-292:
Bill [White] allowed the samurai sword he had sent home from Tarawa to be displayed at Tennessee Wesleyan. A group of Japanese businessmen had come to town to look at buying Mayfield’s Dairy. They visited the college and read the inscription on the blade. Word spread back in Japan that the sword had turned up in Athens, Tennessee. The Japanese government made a formal request for its return. Collectors offered Bill White serious money. He wasn’t interested. But he made it known that he would return it to the family of the man he’d taken it from.
In 1967, Pakaore Hashitami [sic; see below] arrived in the United States and traveled to the Tellico Lodge in the mountains of East Tennessee to meet the man who had killed his father. He admired the polished sharkskin scabbard and gold-tipped handle of his father’s sword. Before he could accept, he asked Bill to tell him how his father died. He had to know that he had lost his life honorably. Bill told him the story of Swede and the concrete blockhouse on Tarawa. Hashitami bowed to Bill, drew the sword from the scabbard, and held it over his head. Bill realized a second too late that he had given this man room to take a swing at him. Bill took a big step closer. But Hashitami had no intentions of revenge. He thanked Bill for restoring honor to his family. The sword had been with them for four hundred years. Of course, Bill said. The war was over.
There have been many such stories of U.S. Marines returning samurai swords captured on islands in the Pacific, ever since the WWII generation or their children began contemplating their own legacies. But the Japanese name cited above is utterly improbable, and the only place it appears in Google searches is a clip in this book (on page 292 and in the index). The family name is more likely Hashitani (橋谷 'bridge-valley'), and the given name Pakaore is impossible in Japanese. If you search for it online, you'll find links to a few people in India and to images and recipes for pakora. Any name starting with P in Japanese is likely to be of foreign origin, like Pekin, Perusha, Porando, Porutogaru, or even Ponto-cho (< Portuguese ponte 'bridge'). If St. Martin's reprints this book, I urge the author to confirm and correct the name of the samurai descendant who took home his family's sword.
