セイホープロダクツ Company Profile

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 emerged from such inquiries. "Compassion" is the new concept. Rather than pursuing extravagant ideas, we want to delve deeper into a simple concept that everyone can be confident in. We wish to return to our origins to realize this concept. In a time when a diverse array of information is overflowing, misjudging the clear distinction between "purpose" and "means" can render even effective technologies futile. SEIHO will firmly place "principles, fundamentals, and essence" 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.

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 on 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." With over 45 years of experience in underfloor ventilation and moisture control, the company emphasizes that "the underfloor is an environment that greatly affects the durability of the entire home precisely because it is not visible." The article points out that while the underfloor 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, including examples of drying after underfloor flooding, and conveys the necessity of appropriate responses based on the causes. SEIHO states that "the essence lies in not 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.

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 timber prices, increased costs of equipment, a shortage of skilled workers, and prolonged delivery times are not temporary changes but are becoming entrenched as structural changes in 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 a generally unstable environment for housing-related materials. What was once taken for granted—that "necessary materials can be obtained immediately when needed"—is no longer a given. 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 until construction, and limited availability of contractors in certain regions are increasingly common nationwide. In the housing industry, there is a growing sentiment that "construction plans cannot be made with the same sense as before," whether for new builds or renovations, which is becoming the norm across the country. For more details, please be sure to read the 【related materials】【related links】 below. ↓ ↓ ↓
