Ever wondered how much land a samurai might have managed during the Edo period? Or maybe you’re deciphering old property records from rural Japan? Either way, understanding the chō—a traditional unit of area—opens a window into Japan’s agricultural past and present. While modern Japan uses metric units, the chō still lingers in cultural memory and practical use. Let’s explore how to bridge these measurement worlds.
Unit definitions
What is a Japanese chō (chō)?
The chō (町) is a historical Japanese area unit tied to rice production. One chō represented the amount of land a farmer could cultivate with one ox in a single day. Symbol: 町. Common uses: Land measurement, agriculture, historical documents. Definition: 1 chō = 10 tan = 3000 tsubo = approx. 9917.36 m².
What is a square meter (m²)?
The square meter is the SI unit for area, used globally for scientific, commercial, and everyday measurements. Symbol: m². Common uses: Real estate, construction, interior design. Definition: The area of a square with sides measuring 1 meter.
Conversion formula
To convert chō to square meters:
Square meters = Chō × 9917.36
For reverse conversions:
Chō = Square meters ÷ 9917.36
Example calculations
- Converting 3 chō to m²:
3 chō × 9917.36 = 29,752.08 m²
That’s roughly the size of four soccer fields! - Converting 50,000 m² to chō:
50,000 ÷ 9917.36 ≈ 5.04 chō
Imagine five traditional Japanese farms side by side.

From rice fields to real estate: The story behind the units
The chō’s origins trace back to the Edo period (1603–1868), when Japan’s feudal system relied heavily on rice-based taxation. One chō wasn’t just a measurement, it represented economic power. Landlords would assess a farmer’s wealth by how many chō they could cultivate. Fast forward to the Meiji Restoration, and Japan began modernizing its measurement systems. By 1891, the chō was officially defined in metric terms, though it kept its cultural significance.
Square meters entered the scene during Japan’s full metrication in 1959. This shift wasn’t just about standardization, it was a strategic move to align with international trade partners. Interestingly, some older residents in prefectures like Niigata still describe land in chō during casual conversations, blending tradition with modernity.
Interesting facts
- Samurai stipends: Feudal lords often paid retainers in koku of rice, with one koku equaling the rice needed to feed one person for a year. A 100-koku samurai might control about 1 chō of productive land.
- Modern comparisons: Tokyo Disneyland covers approximately 47 chō (465,000 m²), making it about 47 times larger than a single chō.
- Global cousins: The chō is similar in concept to the English acre, which originally represented the area one ox could plow in a day.
- Archival challenges: Historians often convert chō measurements in Edo-period maps to square meters to compare ancient and modern city layouts.
- Cultural preservation: Some sake breweries still reference chō measurements when discussing rice field contracts, maintaining a link to tradition.
