Taisei announced on September 14 that its final conviction for antitrust violations regarding Chuo Shinkansen construction is confirmed after the Supreme Court rejected its appeal. The company will pay a fine of 250 million yen as legal proceedings conclude with no further remedies available.
Taisei Corporation disclosed the decision on September 15, confirming that all legal disputes regarding antitrust charges related to underground terminal station construction have concluded. On September 14, the Supreme Court rejected an appeal filed in March 2023, making the guilty verdict and 250 million yen fine final.
The company stated it is regretful but will strictly accept the ruling while reinforcing compliance. This case highlights rare accountability among major general contractors for antitrust violations, signaling a long-term challenge to restore trust beyond immediate financial penalties.
Taisei must pay 250 million yen, a significant amount compared to typical fines for major builders. This conviction impacts not just quarterly profits but also future bidding qualifications and business reputation.

| Finalization Date | Sept. 14, 2026 | Disclosed Sept. 15 |

| Penalty | 250 million yen | Final |
| Former Advisor | Suspended sentence | Final |
Investors should monitor how Taisei rebuilds internal controls, as the loss of social trust poses a greater risk than the fine itself. Reversing this trend depends on proving the effectiveness of prevention measures to secure future contracts.
Analyst take
While the end of litigation removes uncertainty, it leaves behind reputational damage. Investors should focus on internal audit failures and potential executive accountability rather than the fine amount. The risk of talent loss and the possibility of rebounding through strengthened compliance are key factors for future stock performance.
