Quantifying the utilization of weather information! Let's score based on the responses and consider countermeasures!

In this checklist, by answering all 11 questions, you can quantify your company's utilization of weather information during localized heavy rainfall and quickly identify issues. The diagnostic items include "understanding the weather," such as "I don't really understand what the signs of sudden heavy rain, like linear precipitation zones, are," and "information gathering," such as "I don't have a habit of checking weather information." We also provide detailed explanations of the issues for each item (what is not understood) and the diagnostic results, so please download it and make use of it.

The habit of continuously collecting various weather information related to the site is the key to enhancing safety!

In recent years, there has been a notable increase in heavy rain disasters, with both the frequency and duration of heavy rainfall events, as well as the number of landslide incidents, showing an upward trend. To avoid damage from localized heavy rainfall, it is important not only to monitor warnings and advisories but also to early detect "signs of localized heavy rain" from information about rain and clouds, and to make "comprehensive judgments" in conjunction with established criteria. The related catalog introduces a recommended flow for making judgments using weather information. Please utilize it to enhance safety on-site and for decision-making in operations. 【5 Weather Information Checkpoints】 ■ Are there any days or time periods in the coming week when it will rain? ■ Are there any advisories or warnings regarding rain? ■ Are there any advisory notifications concerning linear precipitation bands? ■ What is the expected rainfall during the forecasted time periods, and how much rain is expected each hour? ■ Is there a risk of strong precipitation areas approaching the site that could bring more rain than the site standards? *For more details, please refer to the PDF document or feel free to contact us.

Not just linear precipitation zones? By understanding signs and trends, we can detect indications more quickly.

I will introduce the "Mechanism of Localized Heavy Rainfall." When a large amount of warm, moist air flows into the lower atmosphere and cold air flows in from above, the atmospheric conditions become very unstable, leading to the development of cumulonimbus clouds. As cumulonimbus clouds form successively in the same location and move eastward, they create a linear precipitation zone, causing heavy rain to persist in the same area. The related catalog provides a more detailed explanation of why localized heavy rainfall occurs, including examples from the heavy rain in northern Kyushu. Please take a look. [Development and Continuation of Cumulonimbus Clouds] - When a large amount of warm, moist air flows into the lower atmosphere and cold air flows in from above, the atmospheric conditions become very unstable, leading to the development of cumulonimbus clouds. - Cumulonimbus clouds form successively in the same location and move eastward, creating a linear precipitation zone that causes heavy rain to persist in the same area. *For more details, please refer to the PDF materials or feel free to contact us.

We will introduce examples of accidents that have occurred in the workplace, such as the incident where five workers were swept away.

In recent years, natural disasters have frequently occurred in Japan, with some region being affected by disasters every year, resulting in significant damage. On August 19, 2009, a flash flood occurred in a drainage channel flowing through Higawa in Naha City, Okinawa Prefecture, sweeping away five workers who were working near the entrance to the underground section of the channel. The related catalog provides detailed explanations of the damage that occurred at the actual work site, including an overview and the weather conditions at the time. Understanding what events have happened in the past may help raise awareness in nearby work sites. Please feel free to download and take a look. 【Damage Case】 <CASE 1: Flash flood in a drainage channel in Naha City, Okinawa Prefecture, sweeping away five workers, four of whom died> ■ On August 19, 2009, at 2 PM, a flash flood occurred in a drainage channel flowing through Higawa in Naha City, Okinawa Prefecture. ■ It is believed that the water depth before the increase was approximately 30 to 50 centimeters. ■ According to the Okinawa Meteorological Observatory, the atmospheric conditions above the site were unstable at the time of the incident, with a thunderstorm warning issued in the morning and a heavy rain and flood warning issued in the afternoon. *For more details, please refer to the PDF document or feel free to contact us.

Our seminar, “Back-Office DX in the Era of Digital Salary Payments,” was featured on HAB News Squash (Hokuriku Asahi Broadcasting) This seminar was co-hosted by Kort Valuta Inc. and Schult Social Insurance & Labor Consultant Office, and was held on January 19, 2026, for companies based in Ishikawa Prefecture https://www.hab.co.jp/news/article/202601217724.php As cashless payments continue to expand, digital salary payments are gaining attention across Japan. The coverage highlights current challenges faced by regional SMEs, including limited information and know-how, as well as key considerations and benefits for implementation. ▶️The seminar video featured in the news is now available on YouTube https://www.youtube.com/watch?v=GlHcFSTrFHM

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.
