Marubeni Corporation (hereinafter, “Marubeni”); J-Raise Investment Limited Partnership funded by The Joyo Bank, Ltd.; Orient Corporation; Sankei Building Co., Ltd.; and Meigin Regional Revitalization No. 1 Investment Limited Partnership funded by The Bank of Nagoya, Ltd. (hereinafter, “the five companies”) have completed an investment (hereinafter, “the investment”) in Digital Securities Co., Ltd. (hereinafter, “DS”), which conducts real estate STO (Security Token Offering) business. The investment is the second made by Marubeni and J-Raise Investment Limited Partnership, following their initial investment in October 2022.*1
Additionally, DS completed its registration as a financial instruments business operator on May 29th, 2025*2 and will launch securities services and asset management services.
Background and Significance
STO is a method of establishing funds by issuing “security tokens” (digital securities) that are issued electronically using distributed ledger technology represented by blockchain technology. Real estate STOs are digital securities whose underlying assets are real estate or rights related to real estate and are attracting attention as a next-generation financial product that differs from conventional real estate securitization products. Assets such as real estate have traditionally been accessible only to institutional investors due to high minimum investment amounts and limited liquidity. However, STO enables these assets to be divided into smaller units, improve liquidity, and make them accessible to individual investors.
Overview of DS’s Services
DS and OwnerShip Co., Ltd. (hereinafter, “OS”), which is responsible for system development, have been involved in establishing STO funds for qualified institutional investors*3 such as banks and insurance companies. The total amount of digital securities issued on the STO platform “OwnerShip,” developed and operated by OS, has expanded to approximately 23.5 billion yen as of the end of December 2024.*4 DS, as a financial instruments business operator, provides comprehensive services from the establishment and sales of STO funds to secondary trading between investors through “OwnerShip.”

Future Outlook
Through the investment, the five companies will contribute to the growth of DS’s business and the development of the STO market. They will also support the initiatives of DS in the STO market, which is expected to serve as a new investment vehicle for individuals, to promote the “shift from savings to investment.”
