1. The construction company violated Article 16, Item 1 of the Building Business Act by contracting with Nihon Ecology Co., Ltd., a non-licensed construction business, for private construction projects in Shimonoseki City, Yamaguchi Prefecture, exceeding the amount specified in Cabinet Order under Article 3, Paragraph 1, Item 2 of the Act. 2. The construction company initially only undertook land grading work but, from around November 2023, contracted for electrical work such as installing solar power equipment, receiving a contract fee of 50 million yen, without holding the necessary license for electrical construction work, in violation of Article 3, Paragraph 1 of the Building Business Act and its enforcement order. 3. In the construction work (including the work in 2), Nihon Ecology did not assign qualified engineers such as a supervising technical engineer, and did not perform all necessary tasks such as construction planning, schedule management, quality control, safety management, and technical guidance. Instead, it delegated the main parts of the contracted construction work to the construction company, which violated Article 22, Paragraph 2 of the Building Business Act by contracting the entire construction work from Nihon Ecology.

The private construction project in Shimonoseki City, Yamaguchi Prefecture (hereinafter referred to as 'the project') involves land development for installing solar power facilities, which requires clearing forests. Considering that even in heavy rain, without construction, forests serve as natural barriers to prevent landslides, the construction company has an obligation to take sufficient measures to prevent sediment disasters during construction. The company violated permit conditions under Article 10-2, Paragraph 4 of the Forest Act (Act No. 249 of 1951) by cutting and altering forests outside the project area and within residual forest land, contrary to the forest land development permit. Additionally, the company failed to adequately strengthen temporary disaster prevention facilities and install sediment basins, leading to insufficient sediment runoff prevention measures. In July of Reiwa 6 (2024), heavy rains caused large quantities of sediment to flow outside the project area, damaging nearby rice fields and waterways, and causing harm to the public due to improper construction practices.
