Mirae Asset to reenter Japan with acquisition of Sanko Securities

Mirae Asset Securities said Thursday that it will reenter Japan by acquiring Sanko Securities, a local brokerage, through its U.S. affiliate. The deal is valued at an estimated 42.6 billion won, with the final price subject to regulatory approvals and other conditions. Mirae Asset plans to build on Sanko’s trading operations, expand financial-product distribution and eventually establish a retail brokerage business in Japan. The move comes as the expanded NISA program encourages more Japanese individuals to invest in stocks and funds.

Mirae Asset’s board approved the purchase of 100 percent of Sanko Securities through Mirae Asset Securities Holdings.

Mirae Asset will inject 100.6 billion won into its U.S. affiliate to fund the acquisition and subsequent business expansion in Japan.

Sanko Securities operates under Japan’s Okasan Securities Group and specializes in proprietary trading using its own capital.

For the fiscal year ended March 2026, Sanko reported net profit of roughly 400 million won and net assets of 39.1 billion won.

Mirae Asset Daewoo, the brokerage’s predecessor, withdrew from Japan in 2016.

A decade after it exited the country, Mirae Asset Securities is set to reenter Japan through its acquisition of local brokerage Sanko Securities, as it looks to expand its presence in a market where retail investment is gaining momentum, the company said Thursday.

The company said its board approved a plan to purchase 100 percent of the stakes in Sanko Securities through its U.S. affiliate, Mirae Asset Securities Holdings. The deal is valued at an estimated 42.6 billion won ($35.62 million), with the final price to be determined at closing after regulatory approvals and other conditions are met.

Sanko, which operates under Japan’s Okasan Securities Group, specializes in proprietary trading — buying and selling stocks, bonds and other securities with its own capital to generate returns. It posted a net profit of roughly 400 million won and net assets of 39.1 billion won for the fiscal year ended March 2026, the company said.

The acquisition will give Mirae Asset a foothold in the country’s securities market as it looks to build on Sanko’s existing trading operations, broaden its distribution of financial products and eventually establish a full-fledged retail brokerage business in Japan.

Its move marks a return to Japan 10 years after Mirae Asset Daewoo, the brokerage’s predecessor, withdrew from the market in 2016.

The renewed push comes as Japan’s investment landscape changes.

Years of sluggish growth and ultralow interest rates, alongside tighter international financial regulations, had made it a challenging market for foreign financial firms. But the 2024 expansion of the Nippon Individual Savings Account (NISA) program, which offers tax advantages for investments, has encouraged more individuals to put their money into stocks and funds.

The growing appetite for investment, coupled with Japanese companies’ financing and M&A needs, is creating openings for overseas firms seeking a foothold in the market. Smaller domestic brokerages grappling with succession issues and an aging customer base may also offer potential acquisition targets.

未来资产证券周四宣布，将通过其美国子公司收购日本本土券商三光证券，重返日本市场。该交易预计价值426亿韩元，最终价格尚需获得监管部门批准并满足其他条件。未来资产计划在三光证券现有交易业务的基础上，拓展金融产品分销渠道，并最终在日本建立零售经纪业务。此举正值日本扩大个人储蓄账户（NISA）计划之际，该计划鼓励更多日本个人投资股票和基金。

未来资产董事会批准通过未来资产证券控股公司收购三光证券100%的股份。

未来资产将向其美国子公司注资 1006 亿韩元，用于收购和随后在日本的业务扩张。

三光证券隶属于日本冈三证券集团，专门利用自有资金进行自营交易。

截至 2026 年 3 月的财政年度，Sanko 公布净利润约为 4 亿韩元，净资产为 391 亿韩元。

未来资产证券周四表示，在退出日本市场十年后，该公司将通过收购当地券商三光证券重新进入日本市场，以期扩大其在零售投资日益增长的市场中的份额。

该公司表示，其董事会已批准一项计划，通过其美国关联公司未来资产证券控股公司收购三光证券100%的股份。该交易估值约为426亿韩元（约合3562万美元），最终价格将在获得监管部门批准并满足其他条件后，于交易完成时确定。

三光证券是日本冈三证券集团旗下的自营交易公司，专门从事自营交易——即利用自有资金买卖股票、债券和其他证券以获取收益。该公司表示，截至2026年3月的财年，其净利润约为4亿韩元，净资产为391亿韩元。

此次收购将使未来资产（Mirae Asset）在日本证券市场站稳脚跟，该公司希望在三光（Sanko）现有交易业务的基础上，扩大其金融产品的分销范围，并最终在日本建立成熟的零售经纪业务。

此举标志着该公司时隔 10 年重返日本市场，此前其前身 Mirae Asset Daewoo 于 2016 年退出了日本市场。

随着日本投资环境的变化，这一新的推动力也随之而来。

多年来经济增长乏力、利率极低，加上国际金融监管趋严，使得日本市场对外国金融公司而言充满挑战。但日本个人储蓄账户（NISA）计划于2024年扩大适用范围，为投资提供税收优惠，鼓励更多个人将资金投入股票和基金。

日益增长的投资需求，加上日本企业融资和并购的需求，为寻求在日本市场站稳脚跟的海外公司创造了机会。一些规模较小的国内券商，由于面临继任问题和客户群体老龄化等挑战，也可能成为潜在的收购目标。
