Star Mica: Finding value in occupied assets
Hosking Partners is a London boutique founded in 2013 by Jeremy Hosking, a portfolio manager at Marathon Asset Management for over 25 years. It runs a single global equity strategy built on the capital-cycle, supply-side approach — contrarian, long-term, and unusually diversified (350+ holdings) under a multi-counsellor model, managing around $5.5bn.
In plain words
This article explains how Star Mica, a Japanese company, profits by buying apartments with tenants (which are 15-20% cheaper than empty ones due to strong tenant protection laws), collecting rent, then renovating and selling them after tenants leave. After 26 years, it owns 3,900 units—10 times more than its biggest rival—creating a moat (a hard-to-copy advantage) that larger builders couldn't replicate. For regular investors, it shows how being first and big in a niche market can lead to sustainable profits. Worth reading for the concrete data on why this model works.
Hosking Partners notes that Japan is currently one of the most attractive investment opportunities, with an overweight allocation in its global portfolio covering 73 stocks, a median price-to-book ratio of 1.4x, and a median market capitalization of $3.9 billion. A newly discovered hidden gem, Star
Theme and Background
This chapter focuses on a overlooked niche within the Japanese real estate market – the arbitrage opportunity in tenanted condos – and introduces Star Mica, a "hidden gem" recently uncovered by Hosking Partners. The report argues that Japan as a whole is undergoing a shareholder governance transformation driven by exchange reforms and the new government, and Star Mica emerges as a unique investment opportunity in this context.
Core Views
- Core investment thesis: Through long-term, patient accumulation of scale, Star Mica has successfully executed pricing arbitrage on Japanese tenanted condos and built a moat that competitors find difficult to replicate. The report believes the company can more than double its scale in the medium term and currently trades at a discount to NAV, offering significant upside.
- Contrarian views:
- Unlike many investors who view Japanese residential properties as "depreciating assets" rather than long-term stores of value, the report points out that it is precisely this market perception and institutional structure (strong tenant protection, underdeveloped secondary market) that creates a sustainable arbitrage opportunity.
- The report argues that the scale threshold for this business is extremely high (requiring 500–1,000 units or more to achieve predictability), and other large builders have failed to replicate it, while Star Mica's success is the result of a "structural moat."
Key Arguments and Data
- Mechanism and durability of pricing arbitrage: Tenanted condo units trade at a 15–20% discount to vacant units due to strong tenant protection. This spread has persisted for 30 years, forming the core profit source.
- Scale barrier: After 26 years of accumulation, the company's portfolio has reached 3,900 units, which the report estimates is more than 10 times larger than the second-largest competitor. Reaching this scale requires a long, low-margin, capital-intensive accumulation period, making it impossible for most firms (including large domestic builders) to replicate.
- Source of cross-cycle profitability: Rental income (¥4.6 billion) covers costs, enabling the company to remain profitable through cycles such as the global financial crisis. Renovation sales generate a gross margin of approximately 15%, which directly converts into profit.
- Structural differences in Japan's secondary market:
| Market | Share of existing home transactions |
|---|---|
| Japan | ~16% |
| UK | 75–85% |
| France | 75–85% |
| US | 75–85% |
- However, driven by government policy initiatives, the premium on new homes (existing homes trade at roughly 40% discount to new builds), urban land scarcity, and population outflow, the secondary market is accelerating growth.
- Historical evidence of capital allocation:
- 2025: Established the first fund in partnership with the Development Bank of Japan (DBJ), placing existing units into the fund to recycle capital, improve capital efficiency, while retaining future return exposure and fee income.
- 2021/22: Repurchased approximately 8% of shares at a deep discount from early backers.
Companies/Assets Involved
- Star Mica: Core target. Market cap of $340 million. Founder and CEO Masashi Mizunaga holds 36% of shares. Business model: buy tenanted condos, collect rent, renovate and sell after tenants move out, capturing a 15–20% discount. Portfolio size: 3,900 units, rental income ¥4.6 billion. Management has no personal trading incentives, adopts team profit sharing and executive equity participation, and the founder receives all compensation in equity. Bullish.
- Other large domestic builders: Multiple attempts to replicate the model have failed due to a lack of local expertise and proper team incentives. Serves as a comparative case, indirectly validating Star Mica's moat.
- Development Bank of Japan (DBJ): Partnered with Star Mica in 2025 to establish the first fund, supporting capital-efficient expansion.
Investment Implications
- Focus on structural arbitrage opportunities in niche Japanese markets: For investors with patience and local operational capability, the Japanese "tenanted condo" niche – overlooked by the mainstream – can produce sustained excess returns due to institutional barriers (tenant protection) and scale barriers.
- Emphasize management's capital allocation and incentive structure: A founder with high ownership and all-equity compensation, no personal trading incentives, and team interests aligned with company performance are key indicators for identifying "long-termist" management.
- Use scale barriers to screen investment targets: In capital-intensive, low-margin, long-accumulation business models, the scale gap between the first mover and the second player (e.g., Star Mica leading by 10x) itself constitutes a powerful competitive barrier and moat.
