What is a Corporation?

Today, let's explore the concept of "corporations" (stock companies). While the term is widely recognized, surprisingly few people truly understand how they actually work.


1. The Basic Concept of Corporations

A corporation is "a company that raises capital by issuing stocks and uses that capital to operate a business." The key point here is that the company's money consists of funds contributed by investors—the shareholders.

Key Terms Explained:

  • Stock (Shares) 📊: Ownership stakes issued by the company
  • Shareholders 👥: People who own stocks; also called investors
  • Profit Distribution 💰: A portion of the company's profits returned to shareholders as "dividends"
💡 In Simple Terms: A corporation is "a system where people pool their money together to run a business and share the results according to their investment proportions."

2. Where Are Stock Certificates? 📄

In the past, physical "stock certificates" existed on paper. You may have seen them in movies or TV dramas.

However, since 2009 in Japan, stocks have been digitized and are now managed through brokerage accounts. Therefore, you'll rarely see paper stock certificates anymore.

🎬 Fun Fact: Those bundles of stock certificates you see in dramas are now relics of the past.

3. Listed vs Unlisted Companies 🏢

Corporations can be broadly divided into two categories:

  • Companies whose stocks can be traded on stock exchanges (such as the Tokyo Stock Exchange)
  • Stock prices are constantly publicly available, and anyone can buy them
  • Examples: Toyota, Sony, Rakuten
  • 1. Listed Companies 📈

  • Companies that don't publicly offer their stocks on exchanges
  • Shareholders are limited to the president, family members, or specific companies
  • Examples: Suntory, Lotte, JTB
  • 2. Unlisted Companies 🔒

💡 Important Point: Even a small corporation with just one employee legally issues "stocks." However, since they're not listed, there's no market price.

4. Stocks and "Control Power" 👑

Have you heard the saying "owning 51% means you can control a company"?

This is because at shareholder meetings—the highest decision-making forum of a company—having a majority of voting rights means you have the power to elect the CEO and decide important policies.

Control by Ownership Percentage:

  • 100% Ownership 👨‍💼: The owner-president has complete freedom to run the company
  • 51%+ Ownership ⚖️: Majority ownership means control of management
  • 30%+ Ownership 🗳️: Strong influence over "special resolutions"
⚠️ Important Note: Even in a "one-person corporation," if another entity buys more than half the shares, that president could potentially be removed. This is how the corporate system works.

5. Historical Background of Corporations 📜

The concept of corporations developed in Europe.

  • The 17th-century Dutch "East India Company" is famous
  • Since maritime trade required enormous capital, they collected small investments from many people
  • They established a system for distributing profits to shareholders
  • The World's First Corporation 🌍

  • The "corporate system" was established during the Meiji Era
  • Eiichi Shibusawa (the face on the new ¥10,000 bill) founded many companies
  • He's called the "Father of Japanese Capitalism" for this reason
  • Corporations in Japan 🇯🇵

🎯 Historical Lesson: Corporations were wisdom born from the need to distribute large risks among many people.

6. Differences from Other Business Forms 🏪

You might wonder, "Do companies other than corporations have stocks?"

Comparison of Main Business Forms:

  • Limited Liability Company (LLC) 🤝
    • Investors = managers as a basic principle
    • No stocks; managed through "equity interests"
    • Examples: Amazon Japan, Apple Japan, Google LLC
  • Limited Company 📋
    • An old system
    • New establishments have been prohibited since 2006
    • Only existing limited companies remain
  • Sole Proprietorship 👤
    • Not a "company" at all
    • The owner's personal assets and business are integrated
    • No concept of stocks
💡 Key Point: The ability to separate investors from managers is the greatest feature of corporations.

7. Risks and Returns of Owning Stocks ⚖️

Owning stocks means both "the possibility of profit" and "the possibility of loss."

  • Company profitability → Gains through dividends and stock price increases
  • For growth companies, stock prices can multiply several times
  • Potential Returns (Profits) 📈

  • Company bankruptcy → Loss up to the amount invested (stock purchase price)
  • Stock price decline results in unrealized losses
  • Potential Risks (Losses) 📉

Important Protection: However, you won't bear debts beyond your investment. This is called limited liability. This is another major feature of corporations.

8. Summary 📝

Has your understanding of "corporations" become clearer?

Key Points Recap:

✅ Corporations raise capital by issuing stocks ✅ Stock certificates are now digitally managed ✅ Stocks exist even in unlisted companies ✅ Ownership percentage determines management control ✅ Historically born to support maritime trade and large-scale businesses ✅ LLCs and sole proprietorships don't have stocks ✅ Shareholders are protected by "limited liability"

🎯 Essential Understanding: A corporation is "a system that separates investment from management" and is the fundamental mechanism supporting modern economies.

This system has enabled investment in large-scale businesses and driven economic development. Understanding corporations is the first step to understanding modern society.
