Nippon Building Fund Inc. (TSE: 8951), an office-focused J-REIT, reported net income of ¥24.4bn for the six months to June 30, 2026, up 26.2% from the prior period. The headline number flatters the underlying business: most of the gain came from selling a single Tokyo property, the Sumitomo Densetsu Building, for ¥10.0bn, which booked a ¥5.19bn gain on sale. Strip that out, and real estate leasing profit, the fund's core earnings measure, rose just 2.1% to ¥23.8bn.
The operating backdrop remains tight. Average occupancy across the 70-property portfolio held at 98.2% for the period, and management says the Tokyo central business district vacancy rate has stayed near 2% for two straight periods, a level low enough that landlords with well-located buildings keep pushing rents higher. Total leasable area across the portfolio stands at 1,260,476 square meters and the fund's cumulative acquisition cost has reached roughly ¥1.56tn.
Portfolio rotation, not just growth
The REIT was busy trading buildings rather than simply collecting rent. In March 2026 it bought the Nihonbashi Honcho M-SQUARE trust beneficiary interest for ¥32.1bn and added to its stake in the Toyosu Bayside Cross Tower for ¥14.8bn; in April it added a smaller ¥246mn stake in the Nishi-Shinjuku Mitsui Building. On the disposal side, beyond the Sumitomo Densetsu sale, the fund agreed in September 2025 to sell the NBF Sapporo Minami-nijo Building for ¥1.9bn, a transaction it completed on July 1, 2026, just after the reporting period closed.
Financing stayed conservative. The interest-bearing debt ratio against total assets (LTV) ended the period at 42.6%, inside the fund's 36%-46% target band and comfortably below its 56% ceiling, while 76.9% of borrowings carry long-term fixed rates. A January equity raise brought in roughly ¥22.7bn to help fund the acquisitions.
A lighter guide ahead
Management's own forecast shows the easy comparisons are over. For the six months to December 2026, it expects operating revenue to fall 6.2% to ¥50.5bn and net income to drop 18.0% to ¥20.0bn, with distributions per unit slipping to ¥2,465 from ¥2,489. The following period, to June 2027, brings a modest recovery: revenue up 1.0% to ¥51.0bn, net income up 2.0% to ¥20.4bn, and distributions per unit rising to ¥2,541.
| Period | Operating revenue | Net income | Distribution per unit |
|---|---|---|---|
| Six months to June 2026 (actual) | ¥53.9bn | ¥24.4bn | ¥2,489 |
| Six months to December 2026 (forecast) | ¥50.5bn | ¥20.0bn | ¥2,465 |
| Six months to June 2027 (forecast) | ¥51.0bn | ¥20.4bn | ¥2,541 |
The pattern is a REIT that used one asset sale to smooth this period's numbers, then told investors plainly that both of the next two periods will run below the June 2026 result before ticking back up. Distributions of ¥2,489 per unit are due to start paying out on September 15, 2026, and the fund's full securities report is scheduled for September 29.
