Japan just got its first digital security backed entirely by land rights, not a building, not a revenue stream from tenants, but the dirt itself. Mitsui & Co. Digital Asset Management has tokenized the leasehold interest beneath AEON Omiya, a large commercial facility in Saitama City, creating a new category of regulated real-world asset security in Asia’s second-largest economy.
The underlying land is valued at approximately ¥8.6 billion, or roughly $55.6 million. Investors can buy in for as little as ¥100,000, which comes out to about $647, and the product carries an expected pre-tax annual yield of 3.4%.
How the deal is structured
The tokens are issued through the ALTERNA platform, which runs on a permissioned blockchain called “ibet for Fin.” It’s a private, regulated blockchain designed specifically for financial instruments in Japan.
Legally, the security is structured as a beneficiary securities issuance trust, meaning the tokens comply with Japan’s Financial Instruments and Exchange Act, the country’s primary securities law.
What makes the asset unusual is what it isolates. Rather than tokenizing an entire commercial property, including the building and its rental income, Mitsui Digital AM carved out only the leasehold rights to the land. The ground lease is a 50-year fixed-term arrangement running through June 2076, which means investors are essentially buying exposure to a half-century of land-use rights underneath a major retail complex.
That distinction matters. Traditional real estate securities expose investors to tenant risk, building maintenance costs, and depreciation. A land-only token strips most of that away. What replaces it is a different set of risks: ground-lease renewal uncertainty and terminal-value questions about what happens when the 50-year term expires.
Loyalty points meet digital securities
Investors who hold at least 10 units of the digital security receive 500 WAON points per year. WAON is AEON’s prepaid card reward network, widely used across the group’s supermarkets, shopping malls, and convenience stores throughout Japan.
For a retail investor putting in the minimum ¥100,000, the WAON points are a modest sweetener. It signals that Japan’s institutional players see tokenized securities not as standalone financial instruments but as components of integrated consumer ecosystems.
What this means for investors
Japan’s FIEA provides clear legal guardrails, and platforms like ALTERNA operate within them.
The 3.4% expected yield deserves some context. Japan’s 10-year government bond yield has been hovering in the low single digits after decades of ultra-low interest rate policy. A 3.4% pre-tax return on a land-backed security with a 50-year lease is competitive within Japan’s fixed-income landscape.
When the fixed-term ground lease hits its expiration in 2076, what happens depends on renewal terms that haven’t been negotiated yet. The minimum investment of roughly $647 is deliberately low, designed to pull retail investors into a product category that has historically been the domain of institutions.
