What is Are?

The are is a unit of area equal to 100 square meters, or a square 10 meters on each side. It was introduced as part of the metric system during the French Revolution. While less commonly used today than the hectare (which equals 100 ares), the are still appears in land registration documents and real estate descriptions in some countries. In Japan and parts of Europe, small plots of land may be described in ares. The prefix "hect-" in hectare literally means one hundred ares.

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.
