"An in-home shelter that won't break even in a magnitude 7 earthquake": Miho Kogyo to exhibit at "Security & Disaster Prevention Comprehensive Exhibition 2026", showcasing "Safety Box", an indoor earthquake-resistant renovation that protects seniors and pets in as little as 10 days.

Miho Kogyo Co., Ltd. (Headquarters: Kanagawa Prefecture, Representative: Tamotsu Miyazaki) will exhibit at the "Security & Disaster Prevention Comprehensive Exhibition 2026" to be held in Osaka in April 2026. At this exhibition, we will showcase "Safety Box", an earthquake-resistant shelter that builds the "strongest evacuation room" indoors without demolishing existing homes. We propose "in-home evacuation" as a new option for elderly people who find it difficult to move to shelters in the event of a large earthquake, and for households with pets.

**■Background: The worsening problem of "shelter refugees" and the slow progress of earthquake-resistant renovations**

In recent years, with frequent earthquakes, making homes earthquake-resistant has become an urgent task. However, rebuilding entire houses or undertaking large-scale renovations are costly and time-consuming, causing many households to hesitate. Especially for those requiring care or families with pets, communal living in shelters is a high hurdle, and the need to "secure safety at home" is rapidly increasing.

**■Three Features of "Safety Box"**

**Overwhelming Strength and Reliability: Patented Technology from Industry-Academia-Government Collaboration** Developed through joint experiments with the Kanagawa Prefectural Safety and Disaster Prevention Bureau and the Kanagawa University Faculty of Engineering. With an "independent foundation and independent steel frame" that does not rely on the existing house structure, it has cleared impact tests equivalent to a magnitude 7 earthquake and pressure tests twice that of a typical two-story house. It is also certified as a recommended product by the NPO Japan Security and Disaster Prevention Association. **Speedy construction in "as little as 10 days" without changing your lifestyle.** There is no need for extensive demolition work or temporary housing. It can be completed in as little as 10 days while you remain in your home. You can choose from sizes of 4.5 tatami mats, 6 tatami mats, or 8 tatami mats to suit your lifestyle. **Design that blends into everyday life, not feeling like a "shelter"**. The exterior and interior are no different from a regular renovation, and it can be comfortably used daily as a bedroom with a care bed or as a living room. Only in an emergency does it transform into a "space to protect lives."

**■ "Security & Disaster Prevention Comprehensive Exhibition 2026" Exhibit Details**

On the day of the exhibition, there will be panel displays where visitors can experience the actual structure of the "Safety Box", and introductions of construction examples.

**Location:** Intex Osaka **Date:** April 15 (Wednesday) - 17 (Friday), 2026 10:00 - 16:30 (until 16:00 on the final day) **Highlights:** How to create the "strongest box" within an existing room. The secrets of its patented structure will be explained in detail.

**[Comment from Representative Director Tamotsu Miyazaki]**

"Even if a building collapses, we will absolutely save lives. The 'Safety Box' exists to protect that 'last line of defense.'

I myself have witnessed successive earthquakes and felt the limitations of existing home renovations. I don't want people to give up on safety just because expensive rebuilding is difficult. That's why we pursued a patented structure that can be installed in as little as 10 days and withstand a magnitude 7 earthquake.

From a special facility for a few, to a standard preparedness for every home. Please come and see and touch it at exhibitions and showrooms. What you'll find there is not just a steel frame, but a 'future' where your family can sleep soundly."
