Seven Industries collaborates on the NTV Wednesday drama "Isn't That a Copy?" with art support. Open stairs and wall-mounted shelves are featured in the drama!

Combining open design aesthetics with ease of construction through pre-drilled holes and specialized fittings. The beams and treads are available in a rich variety of 48 colors.

"TWO BEAM" is a two-beam staircase characterized by its simple structure that secures components with dedicated fittings and an open design that allows light and air to pass through. While the fittings are made of a simple matte black finish, the beams and treads can be coordinated to match indoor settings based on a selection of 48 basic paint colors. Thanks to the pre-drilled beams and dedicated fittings, there is no need for positioning the treads on-site, and the ends of the beams are already cut, enhancing work efficiency at the site. 【Features】 ■ No need for tread positioning on-site ■ A wide variety of colors for treads and beams ■ Formaldehyde emission rating F☆☆☆☆ ■ Slip-resistant coating available (optional) *For more details, please refer to the PDF document or feel free to contact us.

• Wooden stairs

Introducing a case study of the wooden open staircase "TWO BEAM"! A staircase where functionality and design harmonize, creating a stylish living space!

Easy installation and can be added later! We have prepared three types: vertical slats, panels, and horizontal slats!

The "Steel Open Handrail Unit" is a unit that can be easily installed as an add-on. We use handrails that prioritize safety and design, and we offer three types: vertical bars, panel, and horizontal bars. The panel type has an 8mm thick acrylic surface. It can accommodate tread depths of 180 to 240mm and riser heights of 180 to 230mm. 【Three Types】 ■ Vertical Bar Type ■ Panel Type ■ Horizontal Bar Type (Note: Horizontal bars need to be cut on-site) Additionally, we have introduced: ■ Simple Vertical Bar Type ■ Simple Horizontal Bar Type As an option, we can also provide "antiviral and antibacterial treatment" (for wooden parts only). *For more details, please refer to the PDF document or feel free to contact us.

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

In recent times, there has been a growing interest in infection control measures and facility hygiene management. Our company offers non-contact sensor products that are recommended for commercial facilities, food factories, and nursing and caregiving facilities. 【Sensors for Automatic Doors】 ● Light Touch Sensor HA-T401 … When you wave your hand in front of the automatic door, the sensor detects the movement and opens or closes the door. This is recommended for making doors with touch switches non-contact. ● Hand Wave Sensor PF-R5, PF-U2, DHS-1 … Opens and closes the automatic door by waving your hand in front of the sensor. ● Foot Switch PF-01S/01D/03S/05 … Opens and closes the automatic door by placing your foot in the opening. 【Access Control System】 ● Face Recognition + Unmanned Temperature Measurement DS Series … Allows for face recognition along with mask detection and body temperature measurement simultaneously. ● Automatic Disinfectant Spray Dispenser PHW-03B … Automatically sprays disinfectant when you wave your hand in front of the sensor. 【Nursing and Care Sensors】 ● Infrared Bed Exit Sensor "Just Place It Pole-kun" … This bed exit sensor is installed next to the bed and notifies via nurse call when the subject enters the detection range. ◎ For more details, please download the catalog or contact us.

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.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

We will be exhibiting at Offshore Tech Japan (Marine Industry Technology Exhibition 2026) (Booth Number: 1S-S06). In this exhibition, we will introduce our services utilizing marine robots such as autonomous surface vehicles (ASVs) and underwater drones for marine surveys, seagrass bed surveys, ocean and wind condition surveys related to offshore wind power, and the collection of dead fish in aquaculture operations. Event Dates: January 28 (Wednesday) to January 30 (Friday), 2026 Location: Tokyo International Exhibition Center "Tokyo Big Sight," South Exhibition Hall, South 1 Hall (Koto City, Tokyo)
