Real-World Asset Investment Platform Alterna Launches in Japan
Mitsui & Co. Digital Asset Management (Mitsui & Co. DAM) has unveiled Alterna, a novel platform designed to offer retail investors the chance to invest in real-world assets (RWAs). The service launched on Monday following receipt of the necessary regulatory approvals.

RWA-backed security tokens
Alterna enables users to conveniently invest in RWAs that generate stable rental income and other returns. RWAs encompass a wide range of assets, including large-scale real estate properties and infrastructure such as logistics facilities and power plants. By offering security tokens, Alterna opens the door to previously out-of-reach investment opportunities, allowing individuals to invest with a minimum of 100,000 yen. This new service represents an exciting alternative for individuals traditionally more comfortable with cash savings.
The first investment opportunity on the platform will be “Stage Grand Nihonbashi Ningyocho,” a residential building located in the Nihonbashi district. The application begins on June 2.
The platform’s name, Alterna, emphasizes its role as an alternative investment service, offering a fresh approach distinct from conventional options such as bank deposits, stocks, and investment trusts.
More effective portfolio management
Compared to traditional investment types like stocks and bonds, RWAs offer unique risk-return characteristics. With RWA-backed investments, investors can potentially achieve more effective portfolio management. These alternative assets have been garnering interest from institutional investors as well.
The Japanese Government Pension Investment Fund (GPIF), the world’s largest institutional investor, has been investing in alternative assets since 2014. To pursue yields, the GPIF has been expanding its investment portfolio in real assets like real estate and infrastructure.
Easy investment with smartphones
Traditionally, retail investors encountered difficulties investing in large-scale real estate and infrastructure assets. Mitsui & Co. DAM aims to establish an environment where such investments can be made easily via security tokens using smartphones.
Interest in Alterna has been substantial even before its official launch, with over 10,000 pre-registrations recorded earlier this month.
