    Main Image
    Our company conducts R&D to prevent external walls, ceilings, and other non-structural members from falling or to make them resistant to earthquakes. We also provide products that do not collapse. It is a feature of our anti-fall net fences for existing ceilings that fluorescent lamps can be replaced without demolishing the existing ceiling. We conducted a demonstration experiment on 40-kg suspended ceilings and other falling objects and Sojo University conducted a 100-kg loading demonstration experiment. No damage was caused in these experiments. This proved that our products are very practical and safe.

    • Anti-fall net fences for existing ceilings (product name: failsafe anti-fall net fences)

      Anti-fall net fences for existing ceilings (product name: failsafe anti-fall net fences)

      [Product description] This corresponds to anti-fall measures for existing buildings under the Building Standards Act Enforcement Order revised on April 1, 2014. Our failsafe anti-fall net fence can be attached without demolishing an existing ceiling. Hanging bolts, joint nuts, wire fixtures, wire brackets, wires, and anti-fall nets are used under an existing ceiling. We plan, design, propose, and install failsafe measures based on our patented anti-fall net fence according to possible falls from buildings. We have received about 30 requests and inquiries from throughout the nation since the cabinet order issued by the current government (in August 2013). We will work together with a major steel company for quotations and construction.

    • Vibration-absorption suspended ceiling system for newly established and newly built ceilings (product name: SAKCS)

      Vibration-absorption suspended ceiling system for newly established and newly built ceilings (product name: SAKCS)

      [Product description] This is our patented product. It falls under the “Other ceilings” category other than specified ceilings among ceilings that are the object of anti-fall measures and verification routes. These regulations are established by the Building Standards Act Enforcement Order (Notice No.771 by the Ministry of Land, Infrastructure, Transport and Tourism) revised in April 1, 2014. Our vibration-absorption suspended ceiling system for newly established and newly built ceilings (SAKCS) falls under “Other ceilings.” This is in the category other than specified ceilings where the mass of the ceiling is 2 kg or less per square meter. This makes it unnecessary to follow verification routes under the Building Standard Act. Designers have a great advantage of applying for confirmation according to their own safety judgment. Users of this new ceiling system can be competitive both in terms of cost and construction in the future ceiling industry.

    • Anti-fall net fences for architecture (product name: failsafe anti-fall net fence for external walls)

      Anti-fall net fences for architecture (product name: failsafe anti-fall net fence for external walls)

      [Product description] Buildings are required to have their external walls diagnosed periodically under the new system of the Ministry of Land, Infrastructure, Transport and Tourism. The first investigation occurs 10 years after construction or repair of external walls, and it is required to be a total percussion test of external walls. The owner or manager of the building is obliged to make periodic reports. Our failsafe anti-fall net fence for external walls is attached on an existing ceiling using wire fixtures, wire brackets, modesty panels, wires, and anti-fall nets. We plan, design, propose, and install failsafe measures based on our patented anti-fall net fence according to possible falls from buildings. We have received several requests and inquiries for planning and quotation. We will work together with a major steel company for quotations and construction.

    • Vibration-absorption ceiling alteration method with anti-fall nets for ceilings (product name: F&S)

      Vibration-absorption ceiling alteration method with anti-fall nets for ceilings (product name: F&S)

      [Product description] The Building Standards Act Enforcement Order as revised on April 1, 2014 makes it mandatory to prevent parts falling from existing buildings. Our failsafe anti-fall net fence prevents a ceiling from falling due to its displacement in an earthquake. Our attachment method (patent pending) for vibration-absorption ceiling improvement structures with anti-fall nets for ceilings suppresses horizontal ceiling collision impact on internal peripheral wall during construction.

    [Company strength]
    Our failsafe anti-fall net fence can be attached without demolishing an existing ceiling. Hanging bolts, wires, anti-fall nets, and metal accessories are used under an existing ceiling. We plan, design, propose, and install failsafe measures based on our patented anti-fall net fence according to possible falls from buildings. We have received about 40 requests and inquiries from throughout the nation since the current government determined a related cabinet order (in July 2013). We will work together with a major steel company for quotations and construction. We have already made applications for three patents related to our business for inventions by our representative Sakuragi.
    
    [Business description]
    Our company proposes plans and designs for our patented anti-fall net fences for existing ceilings and newly established and newly built vibration-absorption systems for suspended ceilings. (Trade names: anti-fall net fence for existing ceilings and SAKCS.) Our integrated services include quotations and subcontracting. Our patented new ceiling system is a preventive measure against the collapse of deteriorated external walls and suspended ceilings. It falls under the “Other ceilings” category other than specified ceilings under the Building Standards Act Enforcement Order (Ministry of Land, Infrastructure, Transport and Tourism Notice No. 771) as revised in April 1, 2014. Our company does everything regarding development.
    
    [Industry]
    Anti-fall net fences for existing ceilings and newly established and newly built vibration-absorption systems for suspended ceilings planning, design, and construction
    
    [Strength of products/technologies]
    Our failsafe anti-fall net fence underwent a demonstration experiment for a ceiling and other falling objects at the development laboratory. The falling objects included a 40-kg suspended ceiling, 10-kg ALC plate, and 32-kg steel plate. It also underwent an anti-fall net fence loading demonstration experiment at Sojo University, for withstanding pressure from 0?100 kg per 0.09 square meters. Our product suffered no damage from these experiments. We offer a vibration-absorption suspended ceiling system for newly established and newly built ceilings (SAKCS). It falls under the “Other ceilings” category other than specified ceilings where the mass of the ceiling is 2 kg or less per square meter. This makes it unnecessary to follow the verification route based on the Building Standards Act. Designers have a great advantage of applying for confirmation according to their own safety judgment.
    
    [Representative's message]
    Our company was founded in January 2009. Our representative Sakuragi has been committed to personal R&D on anti-fall measures for ceilings for the last 5 years. This is the culmination of 40 years of experience of contributions to society in the architectural field (university, super general contractor, and overseas). The Technical Standards concerning Measures to Prevent the Fall of Ceilings in Buildings were enacted on April 1, 2014 following the trend of the times. Our anti-fall net fence for existing ceilings and our vibration-absorption suspended ceiling and its construction method have already been patented. They comply with the standards and provide effective measures against falls and earthquakes. We hope to engage in joint business with major companies to develop sales channels in Japan and abroad.
    
    [Company structure for market development/overseas expansion]
    Our president and company representative has mainly performed R&D, patent acquisition, and investment thus far. The president and commissioned consultants coordinate planning, design, material acquisition, and construction with partner companies and universities (demonstration experiments, etc.) to promote technical development with business tie-ups. We will establish a domestic sales system by sincere cooperation mainly with major companies. Our products are also sufficiently marketable outside Japan. We are thinking of working together with major foreign-affiliated companies.
