The summer of 2024 continued to have hot days, with temperatures exceeding 30 degrees even into September. According to an announcement by the Japan Meteorological Agency on September 2, the temperatures from June to August 2024 were the highest since the agency began recording statistics in 1898, matching last year's record. We will also discuss why this summer has been so hot, the reasons for the increasing temperatures year by year, and how long this abnormal heat might continue. *For more details on the column, please refer to the related links.

In August 2024, due to the occurrence of an earthquake with a magnitude exceeding 7, originating from the Hyuga-nada Sea, it was considered that the possibility of a Nankai Trough earthquake had increased. Consequently, the government issued a Nankai Trough Earthquake Emergency Information (Warning of Major Earthquake). At that time, one week after the earthquake occurred, the government concluded its "special call for caution" associated with the announcement of the Nankai Trough Earthquake Emergency Information (Warning of Major Earthquake). However, the Nankai Trough earthquake is regarded as a seismic event that could occur at any time. What kind of earthquake is the Nankai Trough earthquake, and what kind of damage is anticipated if it occurs? Let's confirm this along with the earthquake preparedness measures that can be taken individually. *For detailed content of the column, please refer to the related links.

The "Mitsuba Drain" is a drainage pipe with a structure suitable for circulating water and air in the soil. By making the collection inlet continuous and slit-shaped (linear), and increasing the collection area, it achieves overwhelming collection and drainage performance. It is resistant to clogging from deposits such as water stains, and even if one drainage route becomes blocked, water can be diverted to other drainage routes. Additionally, when buried under railway tracks as a countermeasure against mud eruptions, it has excellent pressure resistance to withstand the repeated loads of trains. 【Features】 ■ Overwhelming collection and drainage performance ■ Resistant to clogging ■ Resistant to root intrusion ■ Excellent pressure resistance ■ Suitable for improving soil environment *For more details, please refer to the related link page or feel free to contact us.

An underground drainage system refers to a waterway buried underground, and the method of improving drainage by allowing infiltrated water from the surface to flow through and be drained is called "underground drainage." Historically, underground drainage using bamboo and sod bundles has been practiced, but currently, resin materials are mainstream, and various shapes of underground drainage pipes are available on the market. Our "Mitsuba Drain" is chosen by many companies and municipalities due to its high performance and ease of installation. [Shape Comparison (Partial)] ■ Mitsuba Drain - Multi-drainage channel in one cross-section - Honeycomb structure ■ Perforated Pipe - Single drainage channel in one cross-section - Circular pipe with small holes scattered throughout *For more details, please refer to the related links or feel free to contact us.
