Japanese unit of floor area, ~3.305 m².
Default unit for office leases in Japan. Quoted rent is typically per tsubo per month. 1 tsubo = 2 tatami mats. Convert rent: USD/m²/month × 3.305 = USD/tsubo/month.
Tsubo is part of the measurement vocabulary that institutional Class A occupiers, landlords, and advisers use across APAC markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the APAC definition alongside the global standard so cross-border occupiers can translate quickly.
