What is an STO (Security Token Offering)?

An STO (Security Token Offering) is a fundraising method that leverages blockchain technology to issue digital securities known as security tokens. This approach allows investors to access a broad range of assets—including corporate bonds and real estate—that were previously difficult to fractionalize. Unlike traditional ICOs (Initial Coin Offering), security tokens are subject to legal regulations, enabling highly transparent fundraising that strengthens investor protection.

STOs are positioned for significant growth as legal frameworks advance, technology evolves, and investor awareness increases. Offering greater transparency and efficiency than conventional fundraising methods, STOs can be an appealing choice for both companies and investors. By harnessing blockchain’s capabilities, security tokens as digital securities are creating new opportunities within the established securities markets.

Domestic Regulations and Legal Developments for STOs

In Japan, the Financial Services Agency is spearheading accelerated efforts to establish laws and regulations for STOs. These initiatives focus on promoting a healthy digital securities market and safeguarding investors, with systems being developed in phases.

1. Financial Services Agency Study Groups

The Financial Services Agency, mainly through the "Study Group on Approaches to Digital and Decentralized Finance," is examining ways to foster private innovation and adapt to the digitalization of finance. This group holds ongoing discussions about system design for issuing and distributing digital securities—including STOs—and their alignment with existing financial rules. More detailed debates on specific regulatory structures and possible deregulation are anticipated in the future.

2. Certification of the STO Association

The Japan STO Association has been officially recognized as a self-regulatory organization for digital securities. The association is responsible for enhancing operational transparency and supporting the sound development of the STO industry. Its creation is expected to promote information sharing and the establishment of best practices among market participants.

3. Additional Initiatives

Japan is also making progress through amendments to the Financial Instruments and Exchange Act, revisions to exchange rules, and tax-related measures. These actions are advancing the development of the domestic STO market. Long-term attention remains on the evolution of regulations and their practical application.

Key Benefits of STOs

STOs offer three primary advantages. Each highlights distinct strengths compared to traditional fundraising and investment methods.

Advantage 1: Regulatory Compliance

Since STOs are subject to securities laws and related regulations, they provide stronger investor protection and safety than ICOs. Regulatory compliance helps shield investors from risks like fraud and insufficient disclosure, fostering greater confidence. Specific benefits include:

• Mandatory Disclosure: STO issuers must provide investors with detailed information, such as business plans and financials, enabling informed investment decisions.
• Offering Restrictions: STOs are offered only to a select group of qualified investors—such as institutions or high-net-worth individuals—rather than the general public. This ensures investor eligibility and enhances risk management.
• Exchange Regulation: STOs can be traded on regulated securities and crypto-asset exchanges, which are held to high compliance standards.

These requirements protect investors from fraud and lack of disclosure, making STOs a publicly protected asset class. Legal compliance boosts market credibility and forms a foundation for sustainable growth.

Advantage 2: Enhanced Liquidity

STOs may offer greater liquidity than traditional equities since they can be listed on securities exchanges or traded on crypto-asset platforms. Enhanced liquidity is a major benefit, allowing investors to convert assets more easily and supporting transparent price discovery.

STOs can begin trading on exchanges immediately after issuance, supporting the development of secondary markets. While unlisted shares and real estate investments often require lengthy holding periods, STOs enable faster transactions via blockchain. Greater liquidity reduces price volatility risk and attracts more investors. It also stimulates the market and promotes more efficient pricing.

Advantage 3: Cost Efficiency

By leveraging blockchain technology, STOs significantly reduce the costs associated with issuing and trading securities. The traditional securities process involves many intermediaries—each charging fees—but STOs minimize these expenses. Key benefits include:

• Removal of Intermediaries: STOs can be issued and traded without securities firms or other middlemen. Blockchain-based direct transactions eliminate intermediary fees.
• Streamlined Processes: Blockchain automates and streamlines administrative tasks related to issuance and trading. Smart contracts enable rapid, accurate execution of complex operations.
• Lower Costs: By avoiding intermediaries and increasing administrative efficiency, both issuance and trading costs are greatly reduced. This allows issuers to allocate more capital to their businesses and investors to participate at lower cost.

Cost savings are a driving force behind STO adoption, expanding financing opportunities for small and emerging businesses in particular.

Challenges and Drawbacks of STOs

Despite their many advantages, STOs also present several challenges and risks. Understanding these issues is essential when considering STO investment or issuance.

Challenge 1: Regulatory Uncertainty

STOs are a relatively new concept and regulatory frameworks remain incomplete in many countries. Different legal standards—especially for cross-border STO transactions—can pose significant barriers. The absence of clear issuance and trading rules may result in:

• Inadequate Investor Protection: Some regions lack robust measures to safeguard investors due to incomplete regulations.
• Money Laundering and Terrorism Financing Risks: Highly anonymous transactions can make it difficult to prevent illicit financial flows.
• Tax Ambiguity: Unclear tax treatment of STOs can complicate tax compliance for both investors and issuers.

Additionally, the underdevelopment of STO secondary markets may limit trading opportunities. Until regulations are firmly established, caution is advised for both investors and issuers.

Challenge 2: Limited Investor Understanding

Lack of public understanding of cryptocurrencies and STOs is another barrier to wider adoption. STOs require familiarity with blockchain and digital assets, making them less accessible to investors accustomed to traditional products.

Investor education is crucial for understanding STOs. Companies must provide comprehensive information on STO risks and benefits, and investors need to proactively learn about new investment vehicles. A robust approach—including educational programs, seminars, and accessible resources—is essential.

STO Use Cases

Japan has already seen several STO applications, with adoption expanding across various sectors. Here are three key examples:

Example 1: Security Token Issuance by Sony Bank and Sumitomo Mitsui Trust Bank

Recently, Sony Bank and Sumitomo Mitsui Trust Bank announced security token issuances using the Securitize platform—a significant move by Japanese financial institutions into the STO market.

While previous STOs were typically backed by corporate bonds or real estate, this initiative involves security tokens backed by joint investment trusts—a domestic first. This enables more diverse investment options and broadens opportunities for investors.

Example 2: STO Service by LINE Securities

LINE Securities has launched a new STO investment service on its mobile platform, targeting younger investors.

The initial offering introduced Japan’s first publicly offered digital bond for individuals, lowering the barrier for corporate bond investment by allowing small contributions. Users can easily apply, invest, receive interest, and redeem principal through the LINE app, making multi-asset investing more accessible than with traditional products.

Looking ahead, LINE Securities plans to expand STO offerings to unlisted stocks, real estate, physical assets like wine, whiskey, classic cars, and even digital assets such as metaverse land and NFTs. This diversification enables broader portfolio construction for investors.

Example 3: Digital Securities for Rental Housing by Marubeni

Marubeni recently issued digital securities for rental housing, enabling individuals to invest from as little as 100,000 yen per unit—the smallest amount for real estate digital securities in Japan. This lowers the barrier for younger and first-time real estate investors.

Investors can purchase through leading exchanges after opening an account. With several hundred million yen expected in total issuance, investors receive both regular rental income and capital gains on sale, proportional to their holdings. The dual potential for stable cash flow and capital appreciation is particularly attractive.

Marubeni’s initiative highlights a new model for small-scale real estate investment. Where traditional real estate required millions or more, STOs now open the market to a wider range of investors.
