What is Square Meter?

The square meter is the SI derived unit of area, representing a square with sides of one meter. It is the universal standard for measuring floor area in buildings, apartments, and commercial spaces. Real estate listings worldwide specify property sizes in square meters. In construction and architecture, building codes define requirements in terms of square meters. One square meter is approximately the area covered by a standard interior door.

What is Tsubo?

The tsubo is a traditional Japanese unit of area equal to exactly 400/121 square meters (approximately 3.306 m²). It originates from the ken-based measurement system, where one tsubo equals one square ken (about 1.818 m × 1.818 m), or the area of two standard tatami mats. In Japanese real estate, land prices are often quoted per tsubo, and property sizes are commonly described in tsubo alongside square meters. Despite Japan's adoption of the metric system, the tsubo remains deeply embedded in the culture of land and housing transactions.
