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.

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.

We will be exhibiting at the only comprehensive and cross-sectional international convention in the marine field in Japan, "Techno-Ocean 2025." In this exhibition, we will introduce a wide range of specialized survey services related to offshore wind power generation projects, including wind and sea condition surveys, O&M, sediment surveys, and fishing ground environmental monitoring. We will also showcase marine surveys and seagrass bed investigations using marine robots such as autonomous surface vehicles (ASVs) and underwater drones, as well as the collection of dead fish in aquaculture operations.

The energy policy promoted by the government has finally made a significant shift from "quantity to quality." The previous large-scale introduction of renewable energy policies relied on inexpensive foreign-made panels, leading to the chaotic installation of mega-solar farms across Japan's land, which created environmental, landscape, and waste issues. As a result, Japan's energy self-sufficiency rate remains at a mere 13%, and even with the advancement of renewable energy, "import dependence" has not been resolved. In light of this reflection, the focus moving forward will be on "developing domestic energy technologies" and promoting "self-consumption type renewable energy." Among these, perovskite solar cells are lightweight, highly efficient, and offer great flexibility in installation, making them a trump card for "decentralized renewable energy" that can be easily retrofitted onto building walls and roofs. Kenneth Energy Development Co., Ltd. is developing a "selective self-consumption solar power generation system" that utilizes domestic panels and perovskite technology. Based on a track record of 83 projects nationwide and a total construction cost of 908.4 billion yen, it supports the industry's "energy independence." Now, renewable energy is entering an era of "security infrastructure."

"Perovskite solar cells" are once again emerging at the center of Japan's renewable energy policy. Mr. Takai has proposed "nurturing domestic technology for renewable energy" as part of energy and industrial policy, causing related stocks to attract attention in the market as the "Takai trade." The background to this is Japan's long-standing dependence on foreign-made panels in its renewable energy structure. While inexpensive imports have supported proliferation, they have also left a "negative legacy" of forest development, disposal risks, and price fluctuations. If this continues, both the land and energy supply will be controlled by foreign entities—this sense of crisis is the trigger for policy change. Perovskite solar cells possess the trifecta of being lightweight, highly efficient, and low-cost, making installation in existing buildings easy. Development is progressing as a domestic technology, and it is expected to become a mainstay for self-consumption power generation in the future. Kenneth Energy Development Co., Ltd. is developing a "next-generation self-consumption solar power system" with an eye on these perovskite cells. With over 8,000 installations nationwide and expertise in subsidy support, they are turning companies' "energy independence" into reality.
