In the Taishō period, the Japanese banking community was thrown into financial difficulties because of World War I and the 1923 Great Kantō earthquake. In the immediate wake of the earthquake, Yasuda absorbed ten smaller regional banks which lacked a sufficient financial base to cover their deposits. This merger made Yasuda Bank the largest in Japan by several measures, with share capital of 150 million yen, deposits of 542 million yen, loans of 521 million yen, 211 branches and 3,700 employees.
