Our businesses
Security is at our core, combined with building maintenance and digital technology. Because all three sit in one company, the more you combine — security with construction, construction with signage — the fewer suppliers you deal with.
SECURITY
Facility security, traffic control, close protection, AI security
BUILDING MAINTENANCE
Waterproofing, leak sealing, rust prevention and building life extension
SMART SOLUTIONS
Outdoor LED vision, in-building signage, content operation
Licences and certification
Security work may only be carried out by operators certified by a Prefectural Public Safety Commission, and certification requires having a training system in place. We hold Hokkaido Prefectural Public Safety Commission Certification No. 10001029. Anyone can verify the number before signing.
Where we work
We work from our Hokkaido base in Sapporo to sites across Japan. For distant sites, we can start from putting a local team together. On-site checks and quotes are free — just tell us the problem.

Safety first — protecting people, buildings and business.
How we work
We inspect the site, then decide the scope and method. We never quote a figure without looking. The same person handles your enquiry, the site visit and the final sign-off, so you never have to explain the same thing twice.
One team, one order
No need to arrange security, construction and equipment separately
Decided on site
We set out the method and scope, together with the reasons for them
The same person throughout
Your contact does not change from enquiry to sign-off
Businesses and individuals alike
Most of our work comes from condominium and building management companies and facility operators, but we take orders from individuals through the same contact — leak repairs at home, close protection and so on. Security starts from one officer, and we accept single-day jobs.
