was a prominent Japanese financial institution operating from 1876 until 1990. Serving as the primary bank for the Mitsui conglomerate, it consistently ranked among Japan's top banks throughout the 20th century, alongside peers such as Dai-Ichi Bank, Mitsubishi Bank, Sumitomo Bank, and Yasuda / Fuji Bank. In 1943, it combined forces with Dai-Ichi Bank to establish Teikoku Bank (, ). Dai-Ichi Bank was separated again in 1948, and the institution reclaimed the Mitsui Bank name in 1954.
In 1990, Mitsui Bank joined with Taiyo Kobe Bank to form Mitsui Taiyo Kobe Bank (MTKB), which was rebranded as Sakura Bank in 1992, eventually becoming part of Sumitomo Mitsui Banking Corporation (SMBC).
Early development
Banking activities by the Mitsui family commenced in 1683 when Mitsui Takatoshi received authorization from the Tokugawa Shogunate to operate as a money changer.
Established as a private enterprise in July 1876 with initial capital of two million yen, Mitsui Bank functioned as one of the government's principal banks for handling deposits and tax payments until the Bank of Japan was founded in 1882. Over the following decades, the Mitsui family grew into a significant zaibatsu conglomerate, with Mitsui Bank forming a central component. The bank transitioned into an unlimited partnership in 1893 and later incorporated as a limited company with capital stock of ¥20 million in 1909.
By 1929, Mitsui Bank operated six branches beyond Japan and its territories, including locations in London and New York City. This international reach surpassed that of Mitsubishi and Yasuda Banks but was less extensive than Sumitomo Bank or specialized entities like the Yokohama Specie Bank, which held public responsibilities for foreign trade under special laws.
World War II
Around 1937, amid World War II, Mitsui Bank sought to separate itself from the Mitsui zaibatsu due to concerns that its substantial loans to munitions manufacturers could result in postwar financial instability. To address this risk, Mitsui’s chairman orchestrated a merger with Dai-Ichi Bank, creating a larger organization beyond direct Mitsui family control. This merger took effect in April 1943, forming Teikoku Bank.
During the war, Teikoku faced liquidity shortages and mainly offered short-term financing, while long-term loans for munitions producers were provided by the Industrial Bank of Japan. Cultural disparities between Dai-Ichi and Mitsui led to internal tensions; as a result, full integration never occurred, culminating in Dai-Ichi’s withdrawal from Teikoku in October 1948.
Postwar era
In May 1949, Teikoku Bank was listed on both Tokyo and Osaka stock exchanges before reverting to the Mitsui Bank name in January 1954. It subsequently merged with Toto Bank in April 1968.
Around 1960, Mitsui Bank collaborated with its affiliated trading company, Mitsui & Co., to establish a horizontal keiretsu network comprising firms linked to the former Mitsui conglomerate. This alliance included corporations such as Toyota, Toshiba, Toyo Menka Kaisha, Ishikawajima-Harima Heavy Industries, Showa Aircraft, and Oji Paper.
International expansion efforts saw Mitsui founding The Mitsui Bank of California in Los Angeles in 1974 and acquiring Manufacturers Bank in 1981. The two banks merged that same year to create Mitsui Manufacturers Bank (which was renamed Manufacturers Bank in 1992).
Merger to establish Sakura Bank
In 1989, Mitsui Bank combined with Taiyo Kobe Bank to create Sakura Bank, which became the second largest bank globally, following Dai-Ichi Kangyo Bank, during Japan's asset price bubble. The merger brought together TKB's extensive individual and small business customer segments with Mitsui's focus on institutional clients. This strategic alliance was designed to capitalize on these complementary strengths and improve their competitive position in anticipation of European banking consolidations after deregulation in 1992.
