Fifteenth Bank

It was subsequently reorganized by the Japanese government, and eventually absorbed in 1944 by the Teikoku Bank, itself a predecessor of SMBC Group.

The 15th National Bank was established by a group of high-ranking nobility including Iwakura Tomomi, Tokugawa Yoshikatsu, Yamauchi Toyonori, Kuroda Nagatomo, Ikeda Akimasa, Tōdō Takakiyo, Matsudaira Mochiaki, Nanbu Toshiyuki, and Yoshikawa Tsunetake [ja], and was therefore colloquially known as the "Kazoku Bank".

The Imperial Household Ministry had designated the bank's shares as hereditary property, which made them hard to sell, compounding the crisis.

Matsukata Iwao sold off most of his personal assets to support his failing bank and, on 29 November 1927, offered to surrender his title to the Imperial Household Ministry.
