[3] Following the Japan–Korea Treaty of 1905 which reduced the Korean Empire to a Japanese protectorate, the dominant status which Dai-Ichi Bank had enjoyed in Korea since 1878 became a matter of debate in Japan.[1]: 76 A debate ensued between Itō and the Japanese finance ministry, with the latter favoring the creation of a Korean branch of the Bank of Japan over that of a stand-alone colonial institution over which Tokyo would have less direct control.[1]: 81 Eventually Itō's position won the debate, and the finance ministry rationalized the decision as preferable to preserve financial stability.[1]: 84-85 Dai-Ichi Bank kept its branches in Seoul and Busan but later in 1909 transferred all its other Korean branches and offices to the Bank of Korea, totalling 220 regular employees and 121 support staff in Chinnampo, Daegu, Gunsan, Hamhung, Incheon, Kaesong, Kyongsong, Masan, Mokpo, Pyongyang, Songjin, Wonsan, and across the Yalu River in Andong.[4] The new institution's first president was Ichihara Morihiro [ja], a former mayor of Yokohama who had joined Dai-Ichi Bank in 1906 to run its Korean network and kept the position until his death in October 1915.Its monetary role was modelled on that of the Bank of Japan, with the key difference that it was allowed to use BOJ banknotes as currency reserve alongside gold and silver.Its banknotes had legal tender status in Korea and also in the Kwantung Leased Territory and the South Manchuria Railway Zone;[1]: 95 they could be exchanged one-to-one with those of the Bank of Japan.[1]: 196 In December 1917, it took over Manchurian operations of the Yokohama Specie Bank, including its issuance privilege and branches in Lüshun, Liaoyang, Tieling and Andong, while acting as a fiscal agent for the Japanese government in the Kwantung Leased Territory.[1]: 129 In February 1924, new legislation deprived the Governor-General of Chōsen of his prior role in the governance of the bank, which came under the sole supervision of the Ministry of Finance.
