About the tsubo
The tsubo is a square ken, 6 shaku on a side. Japan’s 1891 Weights and Measures Act fixed the shaku at 10/33 m, so one tsubo is exactly 400/121 m², about 3.3058 m² or 35.58 sq ft. In farming the same area is called a bu.
Japan made the metric system the sole legal standard in 1959 and finished converting land registries by 1966, so official records use square meters. The tsubo is still used informally, especially for land prices per tsubo. To convert, multiply square meters by 0.3025 to get tsubo, or tsubo by about 3.3058 to get square meters.
