Source text: Mitsui & Co. Digital Asset Management has introduced Japan's first digital security backed solely by land rights, marking a significant innovation in the country's financial landscape. The security is based on the leasehold interest beneath AEON Omiya, a commercial facility in Saitama City, valued at approximately ¥8.6 billion ($55.6 million). Investors can participate with a minimum investment of ¥100,000 ($647), with an expected pre-tax annual yield of 3.4%. The tokens are issued via the ALTERNA platform, operating on the "ibet for Fin" blockchain, and comply with Japan's Financial Instruments and Exchange Act. This unique asset focuses on land-use rights, offering a 50-year fixed-term ground lease, which reduces traditional real estate risks like tenant and maintenance issues. Investors holding at least 10 units receive 500 WAON points annually, integrating financial instruments with consumer rewards.
