Overview

The Sakura Bank was a major Japanese commercial bank that operated during the restructuring of Japan's banking sector in the 1990s. It was created in April 1990 through the merger of Mitsui Bank and Taiyo Kobe Bank. The combined institution initially operated under the name Mitsui Taiyo Kobe Bank, commonly abbreviated as MTKB, before adopting the Sakura Bank name in April 1992. The merger brought together two complementary customer and business bases. Mitsui Bank, whose institutional history extended back to 1876, had strong relationships with large corporations and institutional clients. Taiyo Kobe Bank, established in 1973, had a comparatively broad presence among individuals and small and medium-sized businesses. The transaction was agreed in 1989, near the peak of Japan's asset-price bubble, and was intended to create a bank with greater scale, a stronger national position, and the ability to compete with large European financial institutions that were expected to consolidate after financial deregulation. During the 1990s, Sakura developed into a significant corporate and retail bank, particularly in the Greater Tokyo Area. Its retail franchise became one of its most prominent strengths. The bank was described as Japan's largest retail bank by several measures, including housing-loan and investment-trust sales. Its business therefore covered both traditional corporate banking and mass-market financial services, giving it a broader customer base than a purely wholesale institution. Sakura's expansion took place against a difficult economic background. After the collapse of Japan's asset bubble, banks faced declining collateral values, weak economic conditions, and extensive non-performing loans. Sakura recorded substantial bad-loan write-offs in 1998. It sought financial support from Toyota, one of its major corporate customers, but Toyota declined to provide that support. The episode illustrated the pressure placed on large Japanese banks and the changing relationship between banks and corporate groups during the banking crisis. The bank also participated in the development of new forms of financial distribution. In 2000, Sakura led the consortium that established Japan Net Bank, an online banking venture. It also began discussions with Sony concerning the possible creation of another Japanese online banking operation. These initiatives reflected the bank's effort to respond to technological change, new competitors, and changing consumer expectations. Sakura's independent existence ended on April 1, 2001, when it merged with The Sumitomo Bank. The transaction combined Sakura's retail capabilities and strong presence in eastern Japan with Sumitomo's wholesale business and stronger western-Japan franchise. The merged company became Sumitomo Mitsui Banking Corporation, now generally known as SMBC. At the time, the combination was regarded as creating one of the world's largest banking groups. The Sakura Bank name and corporate identity consequently ceased to operate as an independent banking brand.

History

The Sakura Bank emerged from one of the major combinations in Japan's banking industry at the end of the asset-bubble era. In 1989, Mitsui Bank and Taiyo Kobe Bank agreed to merge. The proposed combination was intended to create a bank with enough scale to compete in an increasingly international and deregulated financial market. At the time, European banks were expected to consolidate, and Japanese institutions were seeking greater size and stronger competitive positions. The merger was completed in April 1990 under the name Mitsui Taiyo Kobe Bank. Its constituent institutions supplied different strengths. Mitsui Bank had a long-established corporate and institutional franchise dating from its 1876 origins. Taiyo Kobe Bank, which had been established in 1973, contributed a broad base of individual and smaller-business customers. The combination was therefore designed not only to increase balance-sheet scale but also to link large-company banking with a substantial retail and small-business network. In April 1992, the bank adopted the Sakura Bank name. During the decade that followed, it became an important corporate and retail institution, with particular strength in the Greater Tokyo Area. Sakura was considered Japan's largest retail bank by several measures, including housing-loan and investment-trust sales. Its activities included deposits, lending, payments, housing finance, investment products, and corporate banking. The bank's SWIFT code, MITKJPJT, retained a reference to the earlier Mitsui Taiyo Kobe name. Sakura's development was constrained by the collapse of Japan's asset and property markets. The resulting decline in asset values and economic weakness produced severe non-performing-loan problems across the banking sector. In 1998, Sakura undertook massive bad-loan write-offs. It approached Toyota, one of its major corporate customers, for financial support, but Toyota rejected the request. This reflected the broader financial stress of the period and the difficulty of relying on traditional corporate relationships to resolve banking-sector balance-sheet problems. The bank also pursued new distribution models. In 2000, it led the consortium that established Japan Net Bank, an online bank. Sakura subsequently entered discussions with Sony about establishing another online banking operation in Japan. These efforts indicated an attempt to develop digital services and respond to emerging competition outside the branch-based banking model. Sakura's final strategic transformation was its merger with The Sumitomo Bank. Approved in June 2000 and completed on April 1, 2001, the merger combined Sakura's retail capabilities and eastern-Japan presence with Sumitomo's wholesale operations and western-Japan strength. The resulting institution, Sumitomo Mitsui Banking Corporation, was regarded at the time as one of the world's largest banking groups. The Sakura Bank brand was retired as an independent corporate identity after the merger.
