セイホープロダクツ Company Overview

A deeper and newer vision of what should be - "Learning from the past to create the future."

In the 21st century, the way human society exists on a global scale is being questioned. In this era of rapid change, what kind of aspirations should we have when engaging in business? SEIHO's new concept naturally arose from such inquiries. "Compassion" is the new concept. Rather than pursuing extravagant ideas, we want to delve deeper into a common concept that everyone can be confident in. To realize this concept, we wish to return to our origins once again. In a time when a diverse array of information is overflowing, if we misinterpret the clear distinction between "purpose" and "means," even effective technology can become futile. SEIHO will firmly place "principles, fundamentals, and roots" as the axis of our management decisions, learning from the wisdom of past sages while creating genuine technologies and services that benefit society.

Business Activities

Design, development, and sales of residential-related equipment.

【interview】 床下だから特別なのではない。住まいにとって、どの場所も風通しは大事。.jpg

It's not special just because it's under the floor. For a home, ventilation is important in every space.

  • COMPANY

"Just because it's under the floor doesn't make it special. 'Ventilation' is an essential theme for the entire home." SEIHO Products Co., Ltd. (hereinafter, SEIHO) has published a new interview article themed around the importance of underfloor ventilation titled "It's not special just because it's under the floor. Ventilation is important for every part of the home." The company emphasizes that "the underfloor area, being unseen, significantly affects the durability of the entire home," based on over 45 years of experience in underfloor ventilation and moisture control. The article points out that while the underfloor area is not easily visible to residents, the stagnation of moisture and heat can lead to wood decay, mold, and termite damage, all of which impact the durability of the home. It also explains that in recent years, as homes have become more airtight, the structure and airflow under the floor have diversified, making it crucial to accurately understand the current situation. The article shares insights gained from the field, such as examples of drying after underfloor flooding, and conveys the necessity for appropriate responses based on the causes. SEIHO states, "The essence lies not in treating the underfloor as special, but in how to ensure ventilation for the entire home," and will continue to provide information for creating proper living environments.

床下・小屋裏・・・いま改めて見直される“見えない空間”.png

In an era of material shortages and rising material costs, what should we prioritize and protect?

  • PRODUCT

Under the floor and in the attic... "Invisible spaces" are being reconsidered now The environment surrounding the housing industry has changed significantly in recent years. Rising lumber prices, increases in equipment costs, a shortage of skilled workers, and prolonged delivery times are all contributing factors. These changes are not temporary; they are becoming established as structural changes within the entire housing industry. Furthermore, in recent years, the global surge in resource prices, the depreciation of the yen, and rising logistics costs have compounded the situation, leading to an overall instability in housing-related materials. The environment where it was once taken for granted that "necessary materials would be readily available when needed" is no longer a certainty. Additionally, the construction and equipment industries continue to face a serious labor shortage. In particular, the aging of veteran craftsmen who support the field is progressing year by year, while securing young talent is not easy. As a result, situations such as difficulty in scheduling construction dates, longer waiting periods before construction, and limited availability of contractors in certain regions are increasingly common nationwide. In the housing industry, there is now a growing sentiment that "construction plans cannot be made with the same sense as before," whether for new builds or renovations.
