"Newpla-kun" is a rainwater storage tank made of a lightweight, durable, and strong reinforced plastic. Its unique design and assembly structure, based on structural analysis technology, improve long-term creep strength compared to conventional recycled PP resin products. After assembly, it maintains a practical void ratio of over 95%, demonstrating high storage effectiveness. It is widely used in public facilities, commercial facilities, welfare facilities, and condominiums. 【Features】 ■ Long-term creep performance complies with the new technology standards of the Japan Rainwater Storage and Infiltration Technology Association. ■ The main body weighs approximately 3 kg, and the elimination of joint components enhances work efficiency. ■ With a minimum facility height of 0.35 m, its applicability in areas with high groundwater levels is expanded. ■ Compatible with both infiltration and storage types. ■ Obtained technical evaluation certification from the Japan Rainwater Storage and Infiltration Technology Association. ■ Awarded the Minister of Land, Infrastructure, Transport and Tourism Prize in the Medium and Small Construction Companies category at the 6th JAPAN Construction International Award. *For more product details, please download the materials.

"Pradam-kun" is a rainwater storage tank that has a significant retention effect due to over 95% void space (in cases where the facility height is 1.2m or more), reducing excavation and residual soil volume, thereby lowering total costs. The accumulated sand and other materials can be easily removed using an inflow device, making maintenance simple, and it can be installed under parking lots due to its excellent compressive strength. 【Features】 ◆ Achieves high water retention with over 95% void ratio! (in cases where the facility height is 1.2m or more) ◆ Excellent seismic strength, usable even under parking lots! ◆ Main components are one part, and assembly is completed by simply connecting dedicated joints! ◆ Usable for both storage and infiltration facilities! *For more details about the product, please download the catalog or contact us.

The Plus Pool is an underground buried plastic rainwater storage tank. Being underground, it doesn't take up space and can be installed in various locations such as residential gardens and small-scale community disaster prevention centers! During normal times, it allows for easy water conservation and an environmentally friendly lifestyle! It can be used for outdoor washing tasks such as watering the garden and washing cars. In emergencies like disasters, it secures valuable domestic water for flushing toilets and laundry! It ensures seismic strength level 2 (equivalent to the Great Hanshin-Awaji Earthquake), allowing for safe use even in emergencies. It has a large capacity that can support a family of four for one month! (Calculated based on one person needing 40 liters per day) It can also be used during power outages with the installation of a hand pump. In February 2021, we renewed the catalog by adding construction example photos!

In accordance with the new technical guidelines of the Public Interest Incorporated Association for Rainwater Retention and Infiltration Technology, we have launched a model-changed new standard "New Trench-kun II" (product dimensions remain unchanged). Improvements have been made compared to the conventional model as follows: - Compliance with the new technical guidelines of the Public Interest Incorporated Association for Rainwater Retention and Infiltration Technology - Improved connection pieces for easier assembly - Elimination of transport pipe ribs, allowing for internal inspection of the tank with a camera The plastic rainwater retention and infiltration facility, infiltration trench "New Trench-kun II," significantly reduces construction area with its excellent void ratio. No piping work is required, assembly is extremely simple with one-touch connections, and construction time is shortened. It is compatible with T-25 and can be installed under parking lots. The unique internal maintenance function of New Trench-kun II makes maintenance very easy. Due to these features, a cost reduction of 0-40% compared to conventional crushed stone trenches is possible (this varies by administration, so please contact us for details). *New Trench-kun II is a previously registered product in the Ministry of Land, Infrastructure, Transport and Tourism's new technology information provision system 'NETIS' (old registration number KT-130092-A).

A pipe filter installed at the inlet of stormwater runoff control facilities to prevent the inflow of debris and sediment. Conventional pipe filters would cause clogging during heavy rainfall, which obstructed the inflow into the stormwater runoff control facilities and led to overflow from the catch basin. The MU-type pipe filter is a groundbreaking product co-developed with the Public Interest Incorporated Association for Rainwater Storage and Infiltration Technology, ensuring that even if the filter section becomes clogged, the inflow of rainwater is maintained.

In recent years, as a measure against flooding and ground subsidence, many municipalities have begun to require the installation of rainwater runoff control facilities during construction and development activities. However, the required measures differ from one administration to another, and the methods for calculating infiltration rates also vary, making this complexity a significant burden for those in charge of design. Our company possesses extensive know-how regarding the planning and calculation of rainwater runoff control facilities for the "Rainwater Retention and Infiltration Facility 'New Trench-kun' and 'New Pla-kun'," which we have developed through discussions with various administrations. Based on this expertise, we offer a service for creating rainwater calculations tailored for design professionals.
