The JICA Indonesia dissemination and demonstration project was introduced in the May 2016 issue of the monthly magazine "Ishigaki."

High storage capacity with a porosity of over 95%! Excellent seismic strength and easy to assemble.

"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.

Outstanding water treatment capability significantly reduces construction area! No piping work required, shortening the construction period! Equipped with maintenance features!

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).

Hotron's vehicle detection sensors allow you to search for products that meet your needs from three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles and notify you with a rotating light, or switch the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.

The "Hotron Non-Contact Switch" allows you to open and close doors without directly touching door knobs or switches, making it hygienic! You can choose from two types: the "Hand Wave Sensor," which only requires you to wave your hand, and the "Foot Switch," which only requires you to place your foot at the entrance. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, restaurants, hospitals, and nursing facilities. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ A wide variety of options to choose from based on application and location ○ Ideal for places where hygiene is a priority, such as food factories and medical facilities ○ Prevents unnecessary detection due to the switch mechanism 【Product Lineup】 ■ Hand Wave Sensor Series ○ Exposed waterproof type, front, down, and side-facing types "PF-R5" ○ Exposed type, front-facing type "PF-R1" ○ Embedded type, front-facing type "PF-U2" ○ Exposed type, downward wide type "PF-R4" ■ Foot Switch Series ○ Slim type with wide opening, vertical beam type "PF-01S" ○ Slim type with wide opening, horizontal beam type "PF-03S" ○ Standard type, horizontal beam type "PF-05" ◎ For more details, please download the catalog or contact us.

Thank you very much for your continued support. We sincerely apologize for the inconvenience, but we will be observing the following schedule as our year-end and New Year holiday. From Saturday, December 27, 2025, to Sunday, January 4, 2026. We will resume normal business operations on Monday, January 5, 2026. During the holiday period, inquiries to the Kanban Workshop will be accepted via the form 24 hours a day, but responses will be provided sequentially on business days. Thank you for your understanding.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
