Mitsubishi Estate said its Marunouchi offices were 0.34% vacant at the end of September 2026. The figure covers the company's own Marunouchi office portfolio, not Tokyo as a whole, and comes from its half-year securities report for April to September.
Marunouchi: leasing plus a sale
The Marunouchi segment's revenue rose by ¥25.1bn to ¥222.9bn, and operating profit rose by ¥14.7bn to ¥64.6bn. The company attributes higher rental income to stronger leasing, lower vacancy and rent increases at existing buildings. Rental revenue from Marunouchi offices was ¥135.2bn, against ¥130.7bn a year earlier.
The segment also booked ¥17.2bn of property sales from sales of held assets, with none in the prior-year half. Segment profit therefore is not purely rent.
Group profit: overseas and a one-off
Group operating profit was ¥187.1bn, up from ¥107.6bn. The overseas segment supplied ¥49.6bn of that, up from ¥11.2bn, on revenue of ¥176.7bn against ¥56.6bn. The company credits US property sales and rental properties, plus UK and Asian property sales.
Separately, Mitsubishi Estate booked a ¥40.1bn gain on sales of investment securities as extraordinary income, below operating profit. A year earlier the securities gain was ¥21.0bn. Net profit attributable to shareholders was ¥129.1bn, against ¥58.1bn.
The report does not break out rent per tsubo for Marunouchi, so the vacancy rate and the rent revisions cannot be tied to a rent figure.
