Cloud management of weather information at construction sites! Notify all stakeholders through business chat! NETIS registration number QS-150021-VE

The disaster prevention board is one of the components of the "Natural Disaster Prevention System ZEROSAI" (Zero Sai) with NETIS registration number QS-150021-VE. It is a web service that centrally manages weather forecast information, observation data, and webcam footage for construction sites such as civil engineering and building projects. Weather forecasts are analyzed on a 500m mesh, providing pinpoint information tailored to the site. When forecasted or observed values exceed the standard thresholds, notifications are instantly sent to the registered email addresses. To respond to sudden rain and lightning, rainfall forecasts are updated every 5 minutes at the shortest, and thunderstorm forecasts are updated every 10 minutes at the shortest. You can also quickly access the "Linear Precipitation Zone Related Information" announced by the Japan Meteorological Agency. It is possible to integrate with business chat applications. The business chats that can be integrated are as follows: LINEWORKS direct Wowtalk Microsoft Teams Notifications can also be sent through your business chat to prevent information leakage.

Sharing weather information on LINE WORKS, Wowtalk, and Microsoft Teams.

The disaster prevention system ZEROSAI has been linked with NETIS registration number QS-150021-VE and various business chats. It allows for instant information sharing during sudden weather changes at construction sites. The business chats that have been integrated are as follows: LINE WORKS direct Wowtalk Microsoft Teams Previously, notifications were only sent via email when weather information exceeded the standard values, but now notifications will also be sent on your business chat to prevent information leaks. *For more details, please refer to the PDF document or feel free to contact us.

Managing weather observation data from construction sites in the cloud using a 4G connection! Greatly contributes to safety measures and disaster prevention!

The N Sensor is one of the components that make up the Natural Disaster Prevention System ZEROSAI (Zero Sai) with NETIS registration number QS-150021-VE. It continuously observes the weather at construction sites, such as civil engineering and architecture, 24 hours a day, providing real-time, high-precision weather information. The observation data is transmitted to a server via a 4G connection, allowing for centralized management of various weather information in the cloud. By accumulating and analyzing the observation data from the site, the accuracy of weather forecasts for wind and temperature is improved. This enables safe planning of work processes and maintains the safety of the work environment. Features: - Real-time observation of the site 24 hours a day - Installation of a black globe thermometer (optional) allows for WBGT (Wet Bulb Globe Temperature) observation in compliance with JIS standards - Observations exceeding the set reference values can be easily identified, and notifications are sent to the designated email address or business chat (LINE WORKS, direct, WowTalk, Microsoft Teams) - Observation data can be output in PDF and CSV formats - Observation values can be viewed on a dedicated website *For more details, please refer to the PDF materials or feel free to contact us.

Utilizing ICT for weather DX! Rapid information sharing! Greatly contributing to safety measures and disaster prevention!

The "Disaster Prevention Light" is one of the components that make up the "Natural Disaster Prevention System ZEROSAI" with NETIS registration number QS-150021-VE. It can reliably and instantly share information with workers on the front lines through an electronic display board and a rotating light. **Features** - Visual information sharing through an electronic display board and rotating light - Rapid information transmission during linear precipitation zones and approaching typhoons - Displays forecast information along with meteorological observation data - Alerts danger with light and sound using a red rotating light in emergencies - Optional three-color display light that lights up according to three levels of danger There are implementation records in both civil engineering and construction. Feel free to utilize our creativity and technical proposals. *For more details, please refer to the PDF materials or feel free to contact us.*

Starting from January 2026, we are pleased to announce that by linking the measurement data collected on the "Fieldroid Cloud" with the BIM/CIM cloud "KOLC+" provided by Cork Inc., it has become possible to centrally display measurement data summaries on the digital twin. (Examples) Measurement of various environmental data using Cloud Logger LTE Forecasting wind speed, rainfall, and heat index using Signroid 2 Temperature and humidity measurement during concrete curing using Ondroid Slope monitoring using Guraloid Displacement measurement using the shape displacement measurement system "G-Gauge" The data measured by the above services is sent to the cloud, enabling graph displays and alert email notifications. With the implementation of the data linkage function, it is now possible to visualize the latest measurement data from the Fieldroid Cloud on the digital twin constructed in "KOLC+".

Regarding the "quotation" used at the forefront of sales activities: "Do we need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving all processes is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating interpretations from the latest National Tax Agency Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." Items sent externally are "generally required to be preserved." Items that have not been sent externally have "no preservation obligation." 2. Judgment from the sending side: "Is it linked to a transaction?" 3. Judgment from the receiving side: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to ensure reliable "version management." ■ Summary.

The first store of the new business format, Petrichor Bakery and Café, developed by Sanmarc Holdings. The name "Petrichor" means "the smell of earth that rises from the ground after it rains." It was named with the desire to provide a place where people can take a break and refresh themselves in a healing space away from the hustle and bustle of everyday life. We have adopted it for the main counter's tabletop. The atmosphere of the counter's tabletop has satisfied the client! Color pattern: Shell FS115 Produced by: Sanmarc Holdings Co., Ltd.
