Xymax Real Estate Institute surveyed the rentable office spaces of buildings expected to be completed in the coming years in Tokyo 23 Wards and released the results as New Office Supply Survey 2014. The rentable space in this survey is the actual new addition (including our estimate) to the office space market. The owner-occupied spaces are excluded from the calculation. New office buildings with over 3,000 tsubo gross floor area are the subject of this survey. New supply is a direct influence on supply and demand balance. Xymax Real Estate Institute plans to release reports on fundamental data like this on a regular basis.
New supply in Tokyo 23 Wards in 2014-2017 is expected to be 175,000 tsubo per annum on average. The data suggests that the concern for the large volume of single-year new supply previously expected for 2016 has been solved with changes in construction schedule. Considering more development projects of less than 10,000 tsubo buildings will be added later, the average annual new supply is expected to be at around 200,000 tsubo, the same level as in 2003-2013.
About 70% of the total new supply will be in the central three wards (Chiyoda, Chuo and Minato).
