Kort Valuta Inc. (Head Office: Shibuya, Tokyo; CEO: Hideki Shibata) is pleased to announce that we will hold our next recruitment event, “Kort Valuta Night,” on November 26, 2025. This recurring event offers an opportunity for potential candidates to casually learn about our company culture and team atmosphere before applying. By lowering the barrier to entry and providing authentic insights from current employees, the event helps participants gain a more concrete sense of what it’s like to work at Kort Valuta. Since the event’s launch, approximately ten attendees have gone on to join the company in a range of roles — including marketing, customer support, and backend engineering.

Our company has been awarded the "Minister of the Environment Award for Climate Change Action for Fiscal Year 2025." This award is presented annually by the Ministry of the Environment to honor individuals and organizations that have made significant contributions to the mitigation and adaptation of climate change. Our efforts to balance energy conservation and comfort through "Akarina," as well as the initiatives we have undertaken together with the companies that have adopted it, have been recognized. We sincerely thank everyone who has supported and adopted Akarina for their invaluable assistance.

We are pleased to announce the development of the vehicle passage time prediction system "MS-VPP," which measures the speed of vehicles approaching construction sites using microwave sensors and informs the predicted passage time through signage and tablets. This system will be available to construction contractors starting in November 2025. ■Product Overview - "MS-VPP" detects vehicles approaching construction sites and measures their speed using microwave sensors, displaying the vehicle speed and the predicted passage time at specified locations on signage and tablets. It can also measure and display data for vehicles passing continuously. - The data control panel connected to the microwave sensor transmits the vehicle speed data and calculated passage prediction time via LTE. By utilizing microwave sensors, it enables accurate detection and speed measurement of vehicles even at night or in bad weather, and since data processing occurs on the receiving side without going through the cloud, information can be displayed without any time lag. - As a result, drivers of construction vehicles exiting from construction entrances and workers directing traffic can understand "how many seconds until a vehicle passes near the site entrance," thereby implementing safety measures in areas with poor visibility.
