About Tsubo

A tsubo (坪) is the traditional Japanese unit of floor area, equal to 400/121 m² (approximately 3.306 m²) - defined as the footprint of two tatami mats placed side by side. It has been the standard for measuring rooms and apartments in Japan for centuries and remains widely used in real estate and architecture today. Apartment sizes in Japan are routinely quoted in tsubo alongside square meters. One tsubo equals approximately 35.58 square feet or 3.95 square yards.

About Acres

An acre is a traditional unit of land area used primarily in the United States, United Kingdom, and countries with British heritage. One acre equals 43,560 ft² or about 4,047 m². Historically based on the area a yoke of oxen could plow in one day, it remains the standard for measuring agricultural land, residential plots, and rural properties. A football field (without end zones) is roughly 1.32 acres, and most suburban house lots range from 0.25 to 1 acre.
