Marimo Asset Management

What Marimo Asset Management does

Marimo Asset Management Co., Ltd. (マリモ・アセットマネジメント株式会社) is a Tokyo-based Japanese real estate asset management company founded in June 2015 and headquartered in Toranomon, Minato-ku. It operates as the asset management company for the listed Marimo Regional Revitalization REIT (Securities Code: 3470) on the Tokyo Stock Exchange REIT Market and independently manages private real estate funds. The company's investment focus is exclusively on regional Japanese real estate — residential, commercial, office, hotel, logistics, and (as of 2026) healthcare properties — under the positioning of "Strengthening Japan from the regions." As of February 2026, J-REIT AUM stood at approximately ¥62.73 billion and private fund AUM at approximately ¥23.5 billion (May 2026), with a 19th period REIT operating revenue of ¥2,514 million. The company is a wholly-owned subsidiary of Marimo Co., Ltd. within the Marimo Holdings group.

The company's core technology platform is the @Property (＠プロパティ) property management system, which supports lease contract management, billing verification, and oversight of external property management companies. Its proprietary capability is in regional real estate investment analysis and underwriting, combining domain specialization (commercial buildings, offices, and income-producing properties outside major metropolitan areas) with a multi-layered governance framework that includes external Compliance Committee members (certified public accountants or lawyers) and external Investment Committee members (real estate appraisers) for transaction approval and conflict-of-interest management. The company holds three hard-to-obtain licenses: a Tokyo Governor real estate broker license (3-98097), an investment advisory approval from the Minister of Land, Infrastructure, Transport and Tourism (No. 98), and a Financial Instruments Business registration with the Kanto Local Finance Bureau (kin-gi 2885).

The business model is recurring asset management fees on AUM. J-REIT fees are defined in the investment corporation's articles of incorporation and disclosed semi-annually in securities reports and asset management reports. Private fund fees are negotiated individually with each investor. Customer segments comprise (1) individual retail investors who purchase REIT units on the TSE, (2) institutional qualified investors (機関投資家) investing via the REIT or as LPs in private funds, and (3) the Marimo Group sponsor ecosystem using the platform for development pipeline exits. Go-to-market is enterprise field sales combined with IR activities — nationwide investor seminars, financial results briefings, and direct dialogue with institutional investors. The organization is intentionally lean: the Investment Department has approximately 4 members and the Fund Management Department approximately 6 members, with active hiring underway across multiple departments to support AUM expansion.
