LIT, LLC — Integrated Protection Company in Sapporo. Security, Investigation, Maintenance, DX, and Lifestyle Support.

Protecting the ordinary of tomorrow.
We match the right service to whatever you are facing.
LIT brings together five businesses — security, building maintenance, LED signage, investigation, and lifestyle support — under one roof. A single point of contact removes the burden of coordinating multiple vendors and the ambiguity over who is responsible.
I need security staff
Facility security, traffic control, event security, parking security, close protection — we design the arrangement around your site.
I am worried about deterioration or waterproofing
Elevator pit waterproofing, rooftop waterproofing, exterior wall repair, leak repair, and life-extension work.
I want to talk about LED signage
Outdoor LED displays, cold-climate specifications, content operation, and advertising revenue models.
Protect everything.
Protect Everything.
Security goes to a security firm. Construction goes to a builder. Investigation goes to an agency. Equipment and DX go somewhere else again. Every time something happens the contact changes, judgements diverge, and responsibility blurs. Response slows, costs pile up, and what truly needed protecting goes unprotected.
That structure cannot protect what it set out to protect.
So we brought security, investigation, maintenance, DX, and lifestyle support together into one company. One point of contact. Every judgement and every responsibility rests with LIT. From our base in Hokkaido we reach sites across Japan, protecting our clients' safety as a whole.
The power to protect comes from integration.
