2025 Japan House of Councillors Election: Everything You Need to Know

On Sunday, July 20, 2025, Japan will hold its 27th House of Councillors regular election. Elections are crucial opportunities that directly impact our lives, but many people wonder: “What is the House of Councillors?” or “How do I vote?” This article provides a comprehensive guide to everything from the electoral system to voting procedures.

1. Understanding Japan’s House of Representatives and House of Councillors

Japan’s Parliament Consists of Two Houses

Japan’s National Diet consists of two houses: the House of Representatives (Shūgiin) and the House of Councillors (Sangiin). This system is called “bicameralism”.

National Diet House of Representatives Members: 465 Term: 4 years (Can be dissolved) Decision-Making Quick responses House of Councillors Members: 248 Term: 6 years (No dissolution) House of Review Long-term perspective

Why Two Houses?

The bicameral system offers these advantages:

  • Careful deliberation: One house reviews decisions made by the other, leading to better conclusions
  • Diverse opinions reflected: Different electoral systems and terms allow a wider range of public voices in politics
  • Prevents concentration of power: The two houses check each other, enabling balanced governance

Historical Background

The current Diet evolved from the Imperial Diet established in 1890 (Meiji 23). Originally consisting of the House of Representatives and the House of Peers, the latter was abolished when the Constitution of Japan took effect in 1947 (Showa 22), replaced by the House of Councillors.

The current Diet Building was completed in 1936 (Showa 11), with the House of Representatives on the left and the House of Councillors on the right when viewed from the front.

4. Understanding the Electoral System

The House of Councillors election uses a “two-vote system”. This means you receive two ballot papers at the polling station and vote differently on each.

House of Councillors Two-Vote System Voter 1st Vote 2nd Vote Constituency Election Write candidate’s name Districts: Prefectural units (Tottori-Shimane, Tokushima-Kochi merged) Seats up for election: 74 (Tokyo +1 vacancy) Choose regional representatives Focus on individual candidates Proportional Representation Write party name or candidate name District: Nationwide (One national constituency) Seats: 50 Open-list system Choose parties/policies Reflects nationwide support

Constituency Election (First Ballot)

Basic System

  • How to vote: Write the candidate’s name
  • Districts: Prefectural units (except Tottori-Shimane and Tokushima-Kochi merged constituencies)
  • Winner determination: Candidates with the most votes win, up to the district’s quota

About Merged Constituencies

Introduced in 2016, this system combines two adjacent prefectures with small populations into one constituency. Currently there are two:

  • Tottori-Shimane constituency
  • Tokushima-Kochi constituency

Proportional Representation (Second Ballot)

Basic System

  • How to vote: Write either party name or candidate name
  • District: Nationwide
  • Seats: 50

What is the Open-List System?

In the House of Councillors proportional representation, candidate lists don’t have predetermined rankings. Winners are determined by individual vote counts within each party’s allocated seats.

How the Open-List System Works 1. Voting Party votes: 5 million Individual votes: 3 million 2. Tallying Total party votes 8 million votes 3. Seat Allocation Calculate by D’Hondt method 5 seats won Winners Determined by Individual Votes Candidate A: 1.2 million → Elected ① Candidate B: 800,000 → Elected ② Candidate C: 500,000 → Elected ③ Candidate D: 300,000 → Elected ④ Candidate E: 200,000 → Elected ⑤ Candidate F: 150,000 → Not elected
  1. Tally each party’s total votes (party votes + individual votes)
  2. Determine each party’s seats using the D’Hondt method
  3. Winners determined by individual vote counts within each party

Special Provision System (Introduced 2019)

A system allowing parties to designate candidates who win preferentially in predetermined order.

  • Winners determined by list order regardless of individual votes
  • Special provision candidates cannot conduct individual campaigns
  • Designed to elect important personnel without nationwide support bases

Seat Allocation Method (D’Hondt Method)

The D’Hondt method is used to allocate proportional representation seats.

How the D’Hondt Method Works STEP 1: Check each party’s vote count Party A: 12 million Party B: 9 million Party C: 3 million STEP 2: Divide votes by 1, 2, 3… Divide each party’s votes by integers and compare the quotients Party A ÷1 12 million ① ÷2 6 million ③ ÷3 4 million ⑤ Party B ÷1 9 million ② ÷2 4.5 million ④ ÷3 3 million Party C ÷1 3 million ÷2 1.5 million ÷3 1 million STEP 3: Allocate seats in order of largest numbers (5 seats in this example) Party A: 3 seats Party B: 2 seats Party C: 0 seats
D’Hondt Method Calculation Example
PartyVotes÷1÷2÷3Seats Won
Party A12 million12 million6 million4 million3 seats
Party B9 million9 million4.5 million3 million2 seats
Party C3 million3 million1.5 million1 million0 seats

※Seats allocated in order of largest numbers (5 seats allocated in this example)

Message to Young Generations

Your Vote Has Power! Try voting before thinking “nothing will change” Reality of Age-Based Voter Turnout 20s 34.6% 60s 71.4% This is why youth voices don’t reach politics! If youth voter turnout increased… ✓ Education policies might improve ✓ Job support and work conditions might improve
