Why Address Formats Vary
Before diving into specific countries, it's important to understand why address formats differ so significantly worldwide:
Historical Factors:
- Colonial influences shaped many addressing systems

- Privacy considerations affected detail levels
1. Japan: Hierarchical Block System
Japan's address system is perhaps the most unique in the world, operating on a fundamentally different principle than Western systems.
Format Structure
Japanese addresses progress from largest to smallest geographic unit:
Postal Code: 150-0001
Prefecture (都道府県): Tokyo (東京都)
Municipality: Shibuya-ku (渋谷区)
District/Area: Shibuya (渋谷)
Block Number: 2-5-10
Building Name (optional): Shibuya Building
Room/Unit Number (optional): Room 405
Recipient Name: Tanaka TaroUnique Characteristics
Hierarchical Organization:
- Starts with prefecture (47 total)
- Progresses to city/ward/area
- Ends with detailed block numbering
- Building and room numbers come last
Block Numbering System:
- Format: X-Y-Z where:
- X = Chome (district subdivision)
- Y = Ban (block number)
- Z = Go (building number)
- Example: "3-5-1 Shibuya" means Chome 3, Block 5, Building 1
Historical Development:
- Evolved from traditional Japanese administrative divisions
- Block system emerged in Edo period (1603-1868)
