About Tsubo (坪)
Tsubo is Japan's most common traditional land measurement unit, still widely used in real estate despite the official metric system adoption in 1966.
- 1 Tsubo (坪) = 3.30579 square meters (exact: 400/121 m²)
- 1 Tsubo = 35.58 square feet
- 1 Tsubo = Area of 2 standard tatami mats (2.04 jō)
- 1 Tsubo = 1/300 Tan = 1/3000 Chō
Historical Definition:
1 Tsubo = 6 shaku × 6 shaku (1 ken square)
- 1 shaku = 10/33 meters
- 6 shaku = 60/33 meters ≈ 1.818 meters
- Therefore: (60/33)² = 3600/1089 = 400/121 m² ≈ 3.306 m²
Common Property Sizes:
- 20-30 Tsubo: Small apartment/condo
- 40 Tsubo: Average suburban house (standard)
- 50-60 Tsubo: Comfortable family home
- 80-100 Tsubo: Large/luxury property
