Exhibiting at "Techno-Ocean 2025" (November 27-29)

We will continue to contribute to the sustainable development of society through various activities to "know the ocean" and "know the Earth."

At our company, we utilize the technology gained through various marine research vessels and land-based research facilities to assist your research in marine surveys, sample collection, chemical analysis and measurement, and equipment design and manufacturing. We conduct various measurements and chemical analyses tailored to your needs, providing proposals for "manufacturing" from the user's perspective. Additionally, we have a track record in stable isotope ratio analysis of lead, strontium, neodymium, lithium, and boron. 【Marine Work Japan Services】 ■ Isotope Analysis ■ Manufacturing ■ Sample Measurement and Analysis ■ Marine Surveys and Observations *For more details, please download the PDF or feel free to contact us.

• Geological Survey

Continuous underwater shooting and mapping through autonomous navigation! Safe and efficient investigation of rocky shore degradation, seagrass beds, and topography.

The autonomous unmanned boat "ASV" is a water vehicle that navigates autonomously using GNSS (Global Navigation Satellite System) and collects various data. Equipped with underwater cameras and side-scan sonars, it can obtain images and weather data, as well as conduct seabed topography surveys. Additionally, remote operation and real-time data communication are possible through LTE connectivity, allowing navigation in Japan's coastal areas. 【Features】 ■ Autonomous navigation through survey line settings ■ Remote operation using mobile phone networks ■ Surveys can be conducted with fixed-point holding ■ Compact size that can be transported by a van ■ Equipped with power supply and LAN ports to accommodate various devices *For more details, please download the PDF or feel free to contact us.

• Other measuring instruments

Collection of large dead fish at aquaculture farms and sediment sampling at aquaculture sites using underwater drones.

We offer a "Sampling Kit for Underwater Drones" that can be tailored to the arms of your underwater drone. We design and manufacture large dead fish recovery kits, grab sediment kits, and core sediment kits utilizing the robotic arm of your underwater drone. Using underwater drones, we can safely and easily address challenges in aquaculture facilities and port facilities. 【Features】 <Large Dead Fish Recovery Kit> ■ Operate buoyancy devices with the robotic arm ■ Capable of recovering dead fish weighing up to 130 kg ■ We can suggest recovery kits based on the target fish *For more details, please download the PDF or feel free to 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.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Seven Corporation has begun research and development related to rust prevention, aiming to expand the functionality of the natural multifunctional aqueous solution "SEA'S 7." This research is being promoted as a collaborative study with the Industrial Technology Research Institute. In recent years, the manufacturing industry has been seeking technologies that balance environmental impact reduction and improved work safety, making rust prevention measures after cleaning a critical issue. This research includes corrosion evaluation using metal test pieces, measurement of weight changes, and durability tests in a circulating water environment, advancing the understanding of rust prevention mechanisms and performance evaluation. In the future, we aim to develop a next-generation SEA'S 7 that incorporates rust prevention functionality in addition to cleaning, disinfection, and deodorization, contributing to the efficiency of manufacturing processes and the reduction of environmental impact.

We are pleased to announce the launch of the "Vertical Aluminum Step Type F." The "Vertical Aluminum Step Type F" is a new type of aluminum ladder specifically designed for excavation sites, based on the existing "Vertical Aluminum Step." The vertical aluminum step is lightweight due to its aluminum construction, making it easy to transport and set up. Additionally, its modular design allows for flexible height combinations (with connecting parts of 0.7m, 1.0m, and 2.0m). The newly launched Type F retains the features of the previous model while providing even greater convenience. <Features of Type F> ■ The hook adjustment range of the fixed part has been expanded. It can be attached to structures ranging from 20mm to 200mm. ■ The length of the stand pipe can be adjusted. The stand pipe can be stored, making transportation and storage easier. <Release Date> January 5, 2026 <Specifications> - Standard set for Type F: 2.4m *Individual sales of the hanging fixed part and connecting parts are available. *Sales of the previous model (stand pipe fixed type) will also continue.
