Why Trading Houses Instead of Japanese Auto Giants (Toyota), Tech Companies (Sony), or Banks?

Warren Buffett's investment in Japan's five major trading houses (Itochu, Mitsubishi Corporation, Mitsui & Co., Sumitomo Corporation, and Marubeni) through Berkshire Hathaway reflects his investment philosophy: a preference for stable, diversified, undervalued companies with economic moats. Below is a multi-dimensional analysis of why trading houses were chosen over other types of Japanese companies, considering Japan's economic structure and industry comparisons.

1. Core Strengths of Trading Houses: Diversification and Stability

• Diversified Business Model: Japanese trading houses are comprehensive conglomerates operating across energy, metals, food, chemicals, retail, finance, and more. This "vertically integrated" model resembles a miniature economy, effectively dispersing risk. For example, Mitsubishi Corporation engages in everything from raw material sourcing to finished product sales, akin to the "economic fortresses" Buffett favors.
• Pillars of Japan's Economic Structure: Originating from the keiretsu system, trading houses serve as core entities for multinational corporations, controlling supply chains and resource allocation. Within Japan's economy, they act as buffers against cyclical volatility. Buffett views them as "hidden giants," similar to Coca-Cola or American Express—stable and indispensable.
• High Dividends and Low Valuation: At the time of investment in 2020, trading houses were undervalued (P/E ratios as low as 5–10x) with dividend yields of 4–5%. Buffett emphasizes "buying wonderful companies at fair prices," and trading houses fit this criterion. They also hold substantial cash reserves and assets, ensuring stable cash flow.

2. Why Not Auto Giants (e.g., Toyota)?

• Cyclical Industry: The automotive sector is heavily impacted by global economics, supply chain disruptions (e.g., chip shortages), and geopolitics. Though Toyota is an industry leader, it faces risks from the EV transition, technological competition (Tesla, BYD), and trade wars. Buffett prefers avoiding high-volatility industries; auto sales are highly sensitive to recessions.
• Lack of Diversification: Toyota focuses on manufacturing. While it has strong moats (brand and technology), its stability is inferior to trading houses' cross-sector diversification. Buffett has stated his aversion to companies reliant on "single-product dominance."
• Valuation and Returns: Toyota commands a high market cap with elevated valuations (P/E of 15–20x) and lower dividend yields (~2–3%), making it less attractive than trading houses' "cheap yet high-yield" profile.

3. Why Not Tech Companies (e.g., Sony)?

• High Risk and Volatility: Tech evolves rapidly, facing disruption and intense competition. Sony excels in entertainment, electronics, and gaming but contends with rivals like Apple and Samsung, alongside post-pandemic demand fluctuations. Buffett traditionally avoids tech stocks (Apple is an exception due to its consumer goods nature), deeming them "unpredictable."
• Non-Essential Products: Sony's offerings (e.g., PlayStation) are consumer electronics—non-essential goods vulnerable to economic downturns. In contrast, trading houses deal in essentials like food and energy, aligning with Buffett's "perpetual business" criteria.
• Structural Issues in Japanese Tech: Japanese tech firms lag Silicon Valley in innovation. Sony's large market cap doesn't guarantee growth certainty. Buffett invested in trading houses as "low-tech, high-stability" alternatives.

4. Why Not Banks?

• Regulatory and Economic Sensitivity: Japanese banks (e.g., MUFG) are exposed to interest rate policies, inflation, and bad loans. Japan's prolonged low-rate environment squeezes profits, and banks are vulnerable to real estate bubbles or global financial crises. Though Buffett has invested in banks (e.g., Wells Fargo), Japanese banks' "zero-interest-rate trap" heightens risk.
• Limited Global Diversification: Japanese banks focus domestically with minimal international expansion. Unlike trading houses' global supply chains (spanning Asia and Africa), banks are more susceptible to local economic drag.
• Returns and Stability: Banks offer high dividends but face volatility and capital adequacy requirements. Trading houses generate steadier cash flow through trade and investments without credit risk exposure.

5. Buffett’s Holistic Investment Logic

• Comparison of Japanese Companies: Within Japan's economy, trading houses act as "connectors," integrating industries like autos, tech, and finance—rather than being single-sector players. This aligns with Buffett's "buy the business, not the stock" philosophy. In 2020, yen depreciation and undervaluation further attracted him (>$6 billion investment).
• Multinational Perspective: Trading houses are truly global, with significant overseas revenue (e.g., resource exports). Toyota/Sony rely more on manufacturing/innovation, while banks are domestically oriented. Buffett sees trading houses as "Japan's version of Berkshire"—diversified and well-managed.
• Long-Term View: Buffett emphasizes "holding forever." Trading houses' century-long history and resilience (e.g., post-WWII rebuilding) make them stand out. Other industries face higher disruption risks.

In summary, Buffett chose trading houses for their perfect blend of stability, value, and economic moats, cemented in Japan's unique economic structure. If Japan’s market continues undervaluing such assets, similar opportunities may arise.
