正和運輸株式会社's former directors, A and B, engaged in fraudulent activities by submitting false corporate and local corporate tax returns to Yakumo Tax Office, resulting in partial tax evasion. On April 15, 2026, the Hakodate District Court sentenced the company to a fine of 10 million yen, director A to 1 year and 2 months imprisonment (probation for 3 years), and director B to 8 months imprisonment (probation for 3 years), with sentences finalized on April 20. This conduct falls under Construction Business Act Article 28, Paragraph 1, Item 3. As a result, Hokkaido issued a business suspension order from June 3 to June 9, 2026, prohibiting all business activities without restrictions on industry, region, or project type. The company also received a business ban order under Construction Business Act Article 29-4, Paragraph 1, with the same scope and period as the suspension.
