Besterra Co., Ltd., the Tokyo-listed demolition and maintenance contractor, disclosed in its half-year securities report that four people died after part of the equipment being dismantled fell during work to demolish an unloader crane at one of its job sites in Kawasaki, Kanagawa, on April 7, 2026. The report, filed with the Kanto Local Finance Bureau on September 11, 2026, says a subsequent search confirmed the identities of those who had gone missing, and that the relevant authorities' inquiry is continuing, with Besterra cooperating fully.
The company's language is deliberately narrow. It says the accident "may" affect its financial position and results, but that the size of any impact is unknown at this stage, and it will disclose developments as they occur. No cause, fault or liability finding appears in the filing.
The accident sits inside an otherwise strong operating half. For the six months to the end of July 2026, revenue rose 15.6% to roughly ¥5.90bn, operating profit more than doubled to ¥574.8mn, and ordinary profit rose 183.2% to ¥609.0mn, as large demolition contracts carried over from the prior year ran ahead of schedule and Besterra picked more selectively among new orders for profitability.
| Metric | Six months to July 2026 | Six months to July 2025 | Change |
|---|---|---|---|
| Revenue | ¥5.90bn | ¥5.10bn | +15.6% |
| Operating profit | ¥574.8mn | ¥226.2mn | +154.1% |
| Ordinary profit | ¥609.0mn | ¥215.1mn | +183.2% |
| Net profit attributable to owners | ¥99.1mn | ¥220.6mn | -55.1% |
That operating strength did not reach the bottom line. Net profit attributable to owners fell 55.1% to ¥99.1mn, because Besterra booked a ¥500.0mn valuation loss on investment securities, only partly offset by a ¥313.9mn gain from selling other holdings. The demolition and maintenance segment itself performed well on its own terms: completed work rose 18.7% to ¥5.86bn and segment profit rose 45.4% to ¥1.28bn, helped by hiring more site supervisors to support bigger jobs.
The balance sheet moved sharply to fund that growth. Besterra took on ¥6.00bn in new long-term borrowings to secure working capital for larger projects, lifting cash to ¥7.65bn and total assets to ¥13.70bn. The equity ratio fell from 64.8% at the prior fiscal year-end to 38.3%. The board also approved an interim dividend of ¥15 per share, payable October 13, 2026.
For a company whose core business is engineered demolition, an accident it still cannot cost carries weight beyond the balance sheet. Besterra's own filing leaves the financial exposure open: the investigation into the Kawasaki accident continues, and the company says only that it will make timely disclosures as developments occur.
