It was with good reason that the Katipunan solicited Japan's aid and alliance. Japan had been friendly to the Filipinos since the Spanish colonial era. Many Filipinos who had fled from Spanish persecution had been welcomed there and given full protection of Japanese laws. Bonifacio tried to purchase arms and ammunition from Japan, but failed due to lack of funds and the uncovering of the Katipunan, José Dizon was part of the committee that the Katipunan formed to secure arms from Japan with the connivance of the Japanese ship captain. Three months later, however, the Katipunan was uncovered and Dizon was among the hundreds who were arrested for rebellion.
