Regarding the "Automatic Stop Function after 10 Years" Automatic stop has been implemented in products manufactured from 2015 onwards. ■ Overview of Inspection Period Notification Function The dedicated controllers and timers for underfloor and attic ventilation fans sold since 2015 are equipped with the safety function mentioned on the left. Starting from November 2025, the automatic stop function will be activated sequentially for products manufactured in 2015. ■ Response Procedure at the Time of Automatic Stop It is expected that customers will contact the sales and installation stores. We ask that sales and installation stores respond according to the following procedures: 1. Conduct a safety inspection based on the "Underfloor and Attic Ventilation Fan Inspection Checklist." * Please ensure to check for looseness and retighten the connections of the controller and timer. If any liquids such as water, oil, or detergent have come into contact, the internal components may corrode, leading to fire hazards; therefore, replacement of the main unit is necessary. 2. If there are no issues, press and hold the set button to restart the operation. ■ Start of Shipment for Controllers/Timers with Inspection Period Notification Function For details regarding the shipment history of timers, please contact our company’s sales representative or quality control department.

In homes where "flooding under the floor" has occurred due to heavy rain, various damages and risks of secondary damage may be lurking in unseen areas. To protect the durability of the house and the health of the family, we have organized the points that should be prioritized for inspection and action. 【Table of Contents】 1. Why is inspecting under the floor essential? 2. 【Emergency Checkpoints】First, check here! A. Presence of flooding or moisture B. Condition of the wood C. Presence of unusual odors D. Signs of termites or pests E. Condition of ventilation openings 3. Immediate response methods when damage is discovered - Mild situations with little standing water or moisture - - Situations with standing water where structural impact is a concern - The damage from flooding under and above the floor due to heavy rain requires significant recovery efforts, including cleanup. We sincerely sympathize with those who have been affected. Please be sure to read the 【related materials】【related links】. ↓ ↓ ↓

Some of you may be hesitant about introducing the effective equipment for pest control under the floor and preventing foundation deterioration (moisture control), known as "underfloor ventilation fans." Why is ventilation under the floor necessary? We have created a page that clearly summarizes the effects of forced ventilation and installation. Under the floor, a certain area of openings is required by the Building Standards Act. In other words, it mandates that there must be a ventilation opening of a certain size for moisture control under the floor. However, when looking at actual single-family homes, there are always ventilation openings, whether they are square grilles or full-perimeter ventilation with foundation packing methods. In recent years, homes using foundation insulation methods (especially in northern regions like Hokkaido) have also been built, but in this method, the underfloor is connected to the interior, and the underfloor is considered part of the interior, so there are no ventilation openings under the floor to prioritize insulation effectiveness. The adoption rate of foundation insulation methods is still low, but moisture issues are not nonexistent. I would like to touch on this topic on another occasion.

The Importance of Customer Management The decline in population due to the aging society and low birthrate has become a social issue, affecting the consumption activities of the public. How can we overcome this? Acquiring new customers is important. At the same time, maintaining relationships with customers that we have worked hard to acquire is arguably even more important. This is because connecting with new customers (business development) incurs the highest costs for a company. If existing customers are satisfied and continue to purchase various products and services, contributing to the company's revenue, it will reduce the costs needed for acquiring new customers, or allow for more investment in business development. Our company has been focusing on the utilization of items aimed at strengthening customer touchpoints, while experimenting and refining our approach. This time, we will organize and present the details of that effort.
