Overview
Bank of Yokohama, commonly known in Japan as Hamagin, is a regional commercial bank headquartered in Yokohama, Kanagawa Prefecture. Founded in 1920, it was established to serve households, businesses, and public-sector customers in Kanagawa and the surrounding metropolitan area. The bank developed in a region that had experienced the failure and reorganization of earlier financial institutions, and it connects its institutional heritage to Yokohama's early modern banking history, including the nineteenth-century Yokohama Exchange Company and the later Dai-Ni Bank. The bank's core business is relationship banking. Its activities include retail deposits and lending, residential and consumer finance, financing for small and medium-sized enterprises, corporate banking, payment and settlement services, securities-related services, asset management, guarantees, research, and other financial activities delivered through group companies and affiliates. Its main economic footprint is in Kanagawa Prefecture and southwestern Tokyo, although it also maintains overseas offices in Shanghai, Singapore, Hong Kong, Bangkok, and New York to support international business connected with Japanese customers and companies. Bank of Yokohama has historically been one of Japan's largest regional banks. Its scale and local presence have made it an important financial intermediary for the Kanagawa economy, including the Yokohama metropolitan area. The brand operates through a large domestic branch and office network and is supported by affiliated businesses such as securities, finance, research, asset management, capital, guarantee, and business-support companies. The group also has an association with Kanagawa Bank and an overseas banking affiliate in Indonesia. A decisive change in the bank's corporate structure occurred in 2015, when Bank of Yokohama announced an agreement to combine with Higashi-Nippon Bank. The transaction was completed in March 2016 through the creation of Concordia Financial Group, a bank holding company designed to combine the two institutions while retaining their operating identities. Bank of Yokohama became Concordia's wholly owned core banking subsidiary, while the holding company assumed the public-market listing. Consequently, Bank of Yokohama itself ceased to be separately listed, and the provided ticker 7186 refers to Concordia Financial Group rather than to the bank as a standalone listed company. Today, Bank of Yokohama remains an active regional bank under Concordia Financial Group. Its positioning is based on local scale, long-standing customer relationships, broad financial-service capabilities, and the ability to connect regional customers with wider domestic and international resources. It is not a globally consumer-facing brand; its significance is primarily institutional and regional within Japan.
History
Bank of Yokohama was founded in 1920 as a regional bank for Kanagawa Prefecture and the neighboring southwestern Tokyo market. Its institutional background is associated with the development of modern finance in Yokohama. The bank links its historical lineage to earlier financial organizations in the city, including the Yokohama Exchange Company, which began operating in 1869 and is described as an early modern Japanese financial institution, and the later Dai-Ni Bank. This historical connection supports the bank's claim to an unusually long banking heritage, although the present-day institution was established in 1920. During the twentieth century, Bank of Yokohama developed as a locally focused commercial bank. Its role was to collect deposits and provide credit to households, local businesses, and larger companies operating in Kanagawa and the Tokyo metropolitan region. Like other Japanese regional banks, it combined branch-based retail banking with corporate lending and payments. Its local concentration gave it a strong relationship with the regional economy, while its size made it one of the most prominent institutions in Japan's regional banking sector. The bank's activities broadened beyond conventional branch banking through a network of subsidiaries and affiliates. These included securities, finance, research, asset management, capital, guarantee, business-support, and card-service businesses. The group also maintained relationships with Kanagawa Bank and other financial institutions. Overseas offices in Shanghai, Singapore, Hong Kong, Bangkok, and New York extended the bank's ability to assist customers with cross-border transactions and international business. A major strategic turning point came in 2015, when Bank of Yokohama announced a merger-related combination with Higashi-Nippon Bank. The transaction reflected the wider consolidation of Japan's regional banking sector and was intended to create a holding-company structure with greater scale. Completion in March 2016 produced Concordia Financial Group, described as Japan's largest regional bank holding company at the time. Bank of Yokohama and Higashi-Nippon Bank remained operating banking entities within the new group, while Concordia became the parent company. The restructuring also changed Bank of Yokohama's stock-market status. Before the transaction, the bank was separately listed. After completion, Bank of Yokohama was delisted and Concordia Financial Group assumed the listed position, including the market identity associated with ticker 7186. Bank of Yokohama became a wholly owned subsidiary and the core operating arm of Concordia. In its current form, Bank of Yokohama is an active regional bank rather than a separately listed public company. It continues to focus mainly on Kanagawa Prefecture and southwestern Tokyo, with a large domestic network and a smaller overseas presence. Its historical identity, local customer base, and integration into Concordia Financial Group define its role: it is both a major regional financial institution in its own right and the principal banking platform of a wider Japanese financial holding company.
