Why this matters for Class A leasing

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.
