In 1874, the steamship Nunobiki Maru was built by Caird & Company in Greenock, Scotland. The ship was first operated by the Stoomvaart Maatschappij Nederland as SS Sindoro. In 1896, it was acquired by Mitsui Bussan. The ship was best known for her delivery of arms. In 1899, Filipino diplomat Mariano Ponce gained the aid of Chinese revolutionary Sun Yat-sen in finding a way to procure arms. Sun sympathized with the Filipino cause during the Philippine–American War and may have seen the Philippines as a staging point for his revolution in China. With Sun's help, Ponce was able to meet pan-AsianJapanese philosopherTōten Miyazaki and Japanese silviculturist Yaroku Nakamura. Sympathizing with the Filipino cause as well, Miyazaki and Nakamura managed to make an arms purchase amounting to 155,000 yen with Japanese trader Kihatiro Okura. This amount included the 18,000 yen used to purchase Nunobiki Maru, the ship used to deliver the arms. With the grant given by Nakamura's brother, Vice Minister of War Yujiro Nakamura, the deal was made. On 20 June 1899, the ship sailed off from Nagasaki. The delivery was composed of 10,000 rifles, six million rounds of ammunition, a single fixed cannon, ten field guns, seven field glasses, pressing machines for gunpowder and ammunition, and other military supplies. In order to avoid the American blockade, the ship was supposed to anchor off Taiwan first before arriving in the Philippines. However, she foundered in a typhoon between Taihoku and Shanghai, and the ship was lost on 21 July 1899. Nunobiki Maru was foundered when she was from the Saddle Islands at the mouth of Yangtze River. Despite the sinking of the Nunobiki Maru, Nakamura pressed on for a second delivery which included 2.5 million rounds of ammunition. However, the remaining crew of the Nunobiki Maru revealed the purpose of the cargo. This resulted in a diplomatic dispute between Japan and the United States. The second delivery never went through. Meanwhile, after the disaster that struck Nunobiki Maru, Miyazaki expressed his suspicion that Nakamura's intentions were driven more by profit than altruism, and came to state to Sun that the arms were defective and that ship herself might have been in bad condition when she set sail. In addition, after the incident, it became more difficult to deliver arms out of Japan.
