Introduction: Why learn about "how politics works"?

When you hear the word "politics," you might imagine complicated debates on the news. But at its heart, politics is really just "creating and implementing the rules that help everyone live happily." Think of it like making school rules or setting the ground rules for hanging out with friends.
In this chapter, we’ll break down the "foundation" of how our modern society functions. It might feel a bit tricky at first, but once you grasp the key points, you'll be just fine!

1. The Basics of Democratic Politics: Deciding Together

Most countries in the world today use "democratic politics" (democracy). This is a system where the citizens (us) decide how the country should be run.

Direct Democracy vs. Indirect Democracy

There are two main ways to make decisions.

  • Direct Democracy: A method where citizens participate in discussions and vote directly. (Think of it like the whole class holding a majority vote.)
  • Indirect Democracy (Representative Democracy): A method where we choose "representatives," who then gather in a parliament or assembly to make decisions. (Think of it like the class representatives from each grade getting together to set school rules.)

【Key Point】
Because modern nations have such large populations, almost all of them use indirect democracy. This is exactly why "who we choose to represent us (i.e., elections)" is so important!

2. The Three Elements of a State and "Sovereignty"

For an entity to be recognized as a "state" (a country), it needs three specific components. These are called the three elements of a state.

  1. Territory: Land, territorial waters, and airspace.
  2. Citizens: The people who live there.
  3. Sovereignty: The supreme power to make final decisions about how the country is run.

【Fun Fact】
Japan operates on "popular sovereignty." This means that the ultimate power lies with us, the people. A long time ago, it was common for kings to hold all sovereignty (monarchical sovereignty), but it took long, hard historical struggles for citizens to win the rights we have today.

3. The "Rule of Law": Even Kings Must Follow the Rules!

A crucial concept in politics is the "rule of law." This is the principle that even those in power must follow the pre-established "law (the Constitution)."

Common Confusion: The Difference from "Rule by Law"

There is a similar term called "rule by law" (or legalism), but it has a different nuance.

  • Rule of Law: Based on the premise that the "content of the law" is just. It exists to restrain those in power.
  • Rule by Law (Legalism): As long as the "formality" is met, the content doesn't matter. It is often used as a tool to control the people (a way of thinking seen in places like old Germany).

【Memorization Tip】
Think of the "Rule of Law" as keeping power-hungry leaders chained up by the "Constitution" to prevent them from running wild!

4. Separation of Powers: Dividing Power to Protect Freedom

If all power is concentrated in one person, that person will almost inevitably become "selfish" (a dictator). To prevent this, national power is split into three parts, a concept known as the separation of powers. It was advocated by the Frenchman Montesquieu in his book The Spirit of the Laws.

【The Roles of the Three Branches】

  • Legislative Branch (The Diet/Parliament): Creates the rules (laws).
  • Executive Branch (The Cabinet): Follows the laws and carries out the actual business of politics.
  • Judicial Branch (The Courts): Decides whether laws are being violated and settles disputes.

【Key Point】
These three branches keep each other in check to maintain balance. This is called "checks and balances."

5. Two Major Patterns of Political Systems: Japan vs. The U.S.

Even in democratic nations, the specific structure varies. Let's learn about the two most famous ones.

① Parliamentary Cabinet System (Japan, U.K.)

A system where the Cabinet (Executive) exists based on the trust of the Diet (Legislative).

  • The Diet selects the Prime Minister.
  • The Cabinet and the Diet must be in a "friendly" (cooperative) relationship.
  • If the Diet thinks, "This Cabinet isn't doing a good job!", it can pass a vote of no confidence. Conversely, the Cabinet can dissolve the House of Representatives.

② Presidential System (U.S., etc.)

A system where the citizens directly elect the "President" (technically through electors).

  • The President and Congress are completely independent and hold significant power over each other.
  • The President cannot dissolve Congress.
  • Congress cannot easily fire the President.

【Common Mistake】
People often mistakenly think that because Japan and the U.S. are both democracies, the Prime Minister and the President are chosen the same way. The major difference is that in Japan, members of the Diet choose the leader (indirectly), whereas in the U.S., the citizens choose the leader (directly)!

6. Political Parties and Elections: The Route to Making Our Voices Heard

Since we cannot participate in politics directly, we voice our opinions through political parties and elections.

The Role of Political Parties

A group of people with similar opinions forms a political party. They try to win elections to turn their policies into reality.

  • Ruling Party: The party currently in charge of the government, carrying out actual policy.
  • Opposition Party: The party that checks the work of the ruling party and proposes alternative plans.

The Rules of Election (4 Principles)

There are four essential rules for a democratic election.

  1. Universal Suffrage: Anyone who reaches a certain age (18 in Japan) can vote.
  2. Equal Suffrage: One person, one vote. Every vote carries the same weight, regardless of wealth.
  3. Secret Ballot: No one else can know who you voted for.
  4. Direct Election: You vote directly for the person you want to represent you.

【Summary for Today】
1. Modern politics centers on indirect democracy, where we select representatives.
2. The Rule of Law and Separation of Powers prevent the abuse of power.
3. Japan uses a Parliamentary Cabinet System, while the U.S. uses a Presidential System.
4. Our opinions are entrusted to political parties through elections.

The mechanics of politics are like the "blueprints for a machine" that keep us living freely and safely. Once you understand how the machine works, the news will become much more interesting and feel like something that truly matters to you!
