Why Japanese companies do so many different things

Japanese conglomerates like Toto or Hitachi often span wildly different industries, a pattern many commenters trace to postwar corporate structures that prioritize lifetime employment, stability, and diversification over shareholder returns. Participants contrast this “J-firm” model with U.S.-style focus and creative destruction, debating whether Japan’s generalist workforce and loose shareholder discipline explain its strength in precision manufacturing — or its long-running “zombie company” problem and economic stagnation. The exchange also probes how Westerners romanticize Japanese work culture, how similar dynamics appear in Korea and Europe, and what, if anything, other countries can selectively borrow without importing the downsides.

Structural reasons for Japanese diversification

  • Many comments accept the article’s core claim: the “J-firm” bundle (lifetime-ish employment, generalist employees, weak shareholder pressure, emphasis on survival) naturally pushes firms to diversify to create and preserve jobs.
  • Diversification is seen as rational when profitability is secondary to stability and when firms accumulate broad process know‑how (e.g., ceramics for both toilets and chip tools).
  • Some argue similar conglomerates elsewhere arise from capital scarcity and high “frictions” for new firms; big groups become the default vehicles for new ventures.

Comparisons with Western corporate models

  • US/Western firms are described as optimizing for focus, high returns on capital, and shareholder value, with a bias toward spinning off or killing small, merely-profitable lines.
  • Several note that Western conglomerates (GE, ITT, IBM, Honeywell, AMF, etc.) used to look more like Japanese groups before financialization and portfolio-style risk management encouraged narrow focus.
  • One frame: in Asia, companies diversify; in the West, shareholders diversify.

Work culture, hierarchy, and “horizontal” claims

  • Multiple commenters from or familiar with Japan and Korea dispute the idea that Japanese firms are “horizontal” or collaborative in a deep sense.
  • They describe steep hierarchies, rigid approval chains, waterfall processes, overtime pressure, and an inability to challenge superiors.
  • The andon/JIT narratives are criticized as ignoring that subcontractors are often ruthlessly squeezed; official guidance warning against labor-cost suppression is cited.
  • Others report more humane experiences in Japanese subsidiaries than in US megacorps, but still note long-hours norms and lower pay.

Zombie firms, stagnation, and tradeoffs

  • Several tie the same institutional bundle to Japan’s long macro stagnation, “zombie companies,” hoarded cash, and poor capital markets.
  • Defenders emphasize stability, lower inequality, and employment continuity; critics stress falling real incomes, aging demographics, and lost dynamism.
  • A recurring theme: you cannot cherry‑pick “nice” elements (stability, tacit knowledge, quality) without also importing the downsides (zombies, low returns, ossification).

Culture, romanticization, and bias

  • Some East Asian commenters argue the article and HN in general romanticize Japan, misreading classism, corporate-status obsession, and subcontractor exploitation as collaboration.
  • Others counter that the piece explicitly discusses weaknesses and that HN also romanticizes other models (e.g., cooperatives), not just Japan.
  • Debate extends to broader Western narratives about Japan vs. China and how media and soft power shape which systems are idealized or distrusted.

Implications for software and org design

  • The article’s claim that J‑mode fits medium volatility but not radical innovation resonates with some; others argue much software is long‑lived and would benefit from J‑style incremental refinement rather than H‑style “visionary” disruption.
  • Several suggest Japanese-style process knowledge, if abstracted, might inform multi‑agent system design, but acknowledge cultural and institutional context is hard to transplant.
