[Revised Edition] Guide to Underfloor Measures That Must Be Checked and Addressed After Heavy Rain Disasters

Exhaust type + diffusion type unit! A subfloor ventilation series that detects humidity conditions and draws in dry air from beneath the floor.

The system detects the amount of water vapor (absolute humidity) and independently controls the exhaust ventilation system and the diffusion fan. When there is a high amount of water vapor, only the diffusion fan operates, and when it is low, the exhaust ventilation system also operates to bring in dry air from below the floor. POINT 1: Optimal independent operation of exhaust and air supply with absolute humidity sensor POINT 2: Optimal deodorization operation with standard phytoncide POINT 3: Detects abnormalities in the underfloor ventilation fan and water issues, displaying them on the controller. 【Features】 ○ Effective against underfloor humidity, condensation, and mold ○ Powerful exhaust and diffusion For more details, please contact us or download the catalog.

Exhaust type + stirring type unit type

It detects the amount of water vapor (absolute humidity) and independently controls the exhaust ventilation system and the mixing fan. When there is a lot of water vapor, only the mixing fan operates, and when there is less, the exhaust ventilation system operates as well, bringing in dry air from below the floor. POINT 1: Optimal independent operation of exhaust and air blowing with absolute humidity sensors POINT 2: Optimal deodorization operation with standard phytoncide POINT 3: Detects abnormalities in the underfloor ventilation fan and water issues, displaying them on the controller. 【Features】 ○ Effective against underfloor humidity, condensation, and mold ○ Powerful exhaust and mixing For more details, please contact us or download the catalog.

A comfortable indoor environment! Prevents condensation and extends the lifespan of the building.

The underfloor ventilation "Kazetaro" maintains a comfortable condition for wood by forcibly introducing air into the underfloor space. It is particularly effective in eliminating condensation. Underfloor ventilation also affects the indoor environment, reducing the conditions for the growth of dust mites and mold, which benefits the health of the family. The Kazetaro unit uses a hybrid sensor to detect the amount of water vapor (humidity) in the outside air, and the hybrid controller independently controls the Kazetaro blower type and Kazetaro mixer type, creating optimal ventilation operation for the wood under the floor. 【Features】 ○ Improves ventilation effectiveness to prevent pest breeding ○ Forcibly introduces air into the underfloor space to prevent condensation ○ Maintains a comfortable condition for wood, extending the lifespan of the building ○ Reduces the conditions for the growth of dust mites and mold, making the indoor environment comfortable For more details, please contact us or download the catalog.

Equipped with a water immersion sensor! Detects leaks due to flooding under the floor, deterioration, and damage to drainage pipes, etc.!

"Kazutarou Basic" is a localized underfloor ventilation system designed to address areas prone to high humidity and stagnation, such as water-related areas and the north side. Equipped with a flooding sensor, it quickly detects not only underfloor flooding due to water damage but also leaks caused by deterioration or damage to drainage pipes, providing peace of mind by alerting you to abnormalities. We offer two models: the timer type with a flooding sensor, "Kazutarou Basic SS," and the standard timer type, "Kazutarou Basic." 【Features】 ■ Equipped with a flooding sensor ■ Detects underfloor flooding and leaks due to deterioration or damage to drainage pipes ■ Supports environments where natural ventilation is insufficient with forced ventilation ■ Safety measures against increasing underfloor flooding and leaks *For more details, please refer to the external link page or feel free to contact us.

Contributes to the prevention of condensation and mold under the floor. A new model compatible with the foundation packing method has been introduced.

The "DRY PRO" Ver3 is an electronic dehumidifying and blowing unit for underfloor use, combining a Peltier cooling device with a dedicated stirring and diffusion-type blower. In addition to the diffusion-type model "TYPE-D" for foundation insulation construction, a new model "TYPE-C" compatible with foundation packing construction has been added to the lineup. It can dehumidify even in areas where moisture tends to accumulate by stirring a wide range of air. It helps suppress moisture and condensation under the floor, contributing to the prevention of mold, pests, and decay fungi in wooden parts under the floor. Furthermore, with the version upgrade in June 2024, a powerful dehumidification operation mode will be added. The surrounding temperature range for dehumidification operation (low-temperature dehumidification operation range) has been expanded, allowing operation at surrounding temperatures down to 5°C. 【Features】 ■ Easy installation with a φ22 drainage hole (no drainage pump required) ■ Automatic operation possible with a dedicated indoor controller ■ The direction of the aluminum duct of the blower can be set freely ■ Dehumidification capacity of 1800mL per day (depending on conditions) ■ Uses fluorine-free electronic cooling technology ■ Compatible with underfloor flooding sensors (optional) *For more details, please refer to the PDF document or feel free to contact us.

In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.

New York and Tokyo, June 26, 2026 - (JCN Newswire) - This year's successful listing of PayPay Corporation (hereinafter "PayPay") on NASDAQ has provided a significant boost. The question now facing Japan's leading innovation companies is no longer "Is a U.S. listing feasible?" but rather "How can we attract global capital and build companies that align with global growth strategies?" The 2nd Japan Go IPO Summit will be held on September 16, 2026, at the Grand Hyatt Tokyo to address this question. This summit is hosted by MarcumAsia and organized by AUM Advisors.
