This refers to the area measured by the shakkanho method, a surveying method used in the Meiji period. It is the area of ​​a square with sides of 6 shaku (1 ken), which is approximately 3.3058 m2. Based on the Chukyo ken standard, 1 tsubo is equivalent to 2 tatami mats.

• 1 shaku = 10/33m
• tsubo = (10/33 x 6) squared m2 = 400/121 m2 = approx. 3.3058 m2

• 1 tsubo = 3.3058 m2
• 1 tsubo = 2.04 tatami mats *The number of tatami mats is based on the Real Estate Fair Trade Council's regulations: 1.62 m2

This refers to square meters. Square meters are the unit of area in the Measurement Act and the International System of Units (SI). One square meter is the area of ​​a square with one meter on each side. In Japan, a meter is written as "米" (rice), so it is sometimes called "square meter." The unit symbol for square meter is "㎡."

• 1 square meter (㎡) = 0.3025 tsubo
• 1 square meter (㎡) = 0.61 tatami mats *The number of tatami mats is based on the Real Estate Fair Trade Council's regulations: 1.62 ㎡

One tatami mat refers to the area of ​​one tatami mat. However, tatami mats are not standardized throughout Japan, and the dimensions vary by region. For this reason, the Real Estate Fair Trade Council Federation defines one tatami mat as an area of ​​1.62 square meters or more.
