Mirae Asset Securities is set to acquire Sanko Securities, a subsidiary of the Okasan Securities Group, for approximately 5 billion yen (about 425 million won). The company plans to leverage the local brokerage's personnel and proprietary trading operations to penetrate the Japanese market. It is expected to begin full-scale operations targeting Japanese financial consumers as early as next year.
According to the Nihon Keizai Shimbun and financial investment industry sources on October 29, Mirae Asset Securities has decided to proceed with the acquisition of Sanko Securities and enter the Japanese stock proprietary trading business. The two parties are expected to announce the details following a board meeting held earlier today.
This acquisition will be conducted through Mirae Asset's U.S. intermediate holding company, targeting the entire stake in Sanko Securities. The acquisition amount is reported to be around 5 billion yen (approximately 425 million won).
Sanko Securities is a proprietary trading firm located in Chuo Ward, Tokyo. Proprietary trading involves securities firms trading financial products such as stocks using their own funds to generate profits. Sanko Securities has focused on proprietary trading since transferring its retail customer business to another company within the group in May.
If the deal goes through, Mirae Asset will inherit Sanko Securities' existing operations and workforce. As of March 2026, Sanko Securities reported net assets of approximately 4.6 billion yen and a net profit of 48 million yen.
Mirae Asset will also obtain the necessary licenses to enter the Japanese securities market. Through this acquisition, the firm will secure the registration required to operate as a 'Type 1 Financial Instruments Business Operator' in Japan, enabling it to engage in trading and underwriting of stocks and bonds.
The Nihon Keizai Shimbun noted that the booming Japanese stock market is prompting foreign securities firms to expand their presence in the region. It added that overseas securities firms are increasingly seeking business opportunities in the Japanese stock market.
