The Missing Documents

When Takenouchi was assigned to Paris as the chief military attaché with the embassy in France, a comfort bag was regularly delivered from a person named Kaoru Takeuchi to his home in Kojimachi, Tokyo. In the spring of 1910, while Heitaro Takeuchi was working at the Kure Naval District Government Building, Takeuchi visited the official residence and asked Takenouchi to visit him. His wife, Nuiko, was the first person to meet Takeuchi, but he was the sender who had been sent a comfort bag for more than a dozen years. In order to prepare her tea, Nuiko returned to the Japanese-style building, leaving the woman alone, and by the time she brought the tea confectionery into the drawing room of the Western-style building about 10 minutes later, Takeuchi had already disappeared. After that, when Takenouchi returned to the official residence about 20 minutes later, he checked the study next to the drawing room and found that the "important confidential documents" in the drawer of the desk had been missing. He immediately contacted the Kure gendarmerie, and although a cordon was set up in

, he was unable to find Takeuchi. Since he was a military attaché in France, Takeuchi had been collecting information such as military information and intelligence activities of the great powers, mainly Russia, and had always been marked and followed by Russian spies and operatives.

After that, Rear-Admiral Takeuchi was placed in fourth rank for his many years of military service. The reasoning why Heitarō resigned is rarely mentioned in official historical sources related to the former Navy. The author's mother, Nobu Maeda (the second daughter of Heitarō), told her daughter in detail about the situation at the time of the incident from Nukio and remains a hidden story published in "No. 17".
