Japan's Leading
Modular Space Provider

Combining the best of innovation with environmentally sound philosophies, we are proud to be a partner in solving your modular space needs.

Durable
Tough space problems call for tough solutions. Our steel, rigid-framed products are strong enough to withstand nature’s harshest elements. The steel girders are also rust-proofed through hot dip zinc galvanising.
Flexible
Our modular buildings are foldable and therefore can be flat-packed for easy transportation. They can be easily remodeled, relocated and removed as your needs change. This also enables us to export products made in Japan more easily.
Fast
As almost all assembly processes are carried out in our factories, our modular buildings require little on-site construction time. Which means speedy assembly, whatever the weather.
Safe
Safety comes first at every stage, from production to installation. Our procedures ensure safety for both our employees and customers.

Tough Protection All Around

To create a comfortable interior without pillars, each unit is defined by a tough box frame that does not require braces or strong walls. Pillarless spaces of up to 9m wide can be created; the largest in Japan’s modular construction industry. In addition, we are constantly increasing safety standards, running tests in the event of natural calamities such as storms and earthquakes.
Fire-proofed for Safety
Fire-resistant phenolic foam is incorporated into the wall and roof insulation. Non-combustible ceiling sheets are installed, and corrosion-resistant cement boards are used for the flooring to improve walking comfort and heat resistance.
Building Certification Compliant (in Japan)
Our modular units comply with building regulations for temporary buildings, and we use a life-sized testing chamber to perform strict checks on the structure to determine it performs as intended. Be it for events or sales offices, or any type of space, we provide buildings that comply with each country’s regulations.
No Proof Wall Required
Because each unit is a structure that supports all loads with just four pillars, there is no need for obstructive sections and load-bearing walls that restrict the layout. The result is an open space with an easy-to-use layout.
The Right Balance of Speed and Safety
The steel foundation* can be easily adjusted by bolting the steel plate and H type steel. Durability and design are improved by plating and phosphate treatment. If required, our team can assist you in acquiring a building permit (only applicable in Japan).

* Because materials are made-to-order, delivery may take time.

Earthquake Resistant

Our products comply with Shizuoka’s earthquake resistance standards, which are the strictest in Japan.

Improved Thermal Insulation
Incorporated in the roof is the same insulation that has been used to fortify the exterior walls of the main building. By reducing the possibility of transferring cold air and heat, we keep the room temperature comfortable throughout summer and winter.

As Flexible As Your Imagination

A simple, sophisticated design that can be used both for temporary and permanent installation: the Box Connection. Buildings are simply installed by following the instructions as stated in the manual. The design of the links between the frame and panels have been thoroughly thought through, and the unit does not use temporary joints.
Any Size, Every Need

Each unit can be connected vertically and horizontally, accommodating to various space sizes and needs.

Concealed Electrical Fixtures for a Clean, Modern Interior
In every unit’s electrical system, an EPS panel is adopted, concealing the wiring. The single phase, 3-wire system and 200V electrical lamp used now correspond to normal standards.

Our Flatpack Transport System

To ensure fast construction, we designed our modular units to be folded into a flat, easily transported state. This allows up to six units to be transported at once, a time and cost-saving feature that can reduce CO2 emissions by 1/6.
Step 1
After factory production, modular units are ready to be transported to the construction site. The flatpack system allows up to six units to be loaded at a time.
Construction begins with a crane – the roof of the unit is lifted, to allow the rest of the unit to unfold.
Step 2
At the construction site, only a crane and a small team will be needed to unpack the units. As each unit is constructed to support all loads with four pillars, there is no need to install additional sections or load-bearing walls.
Depending on the design of the units, glass panels, windows, doors or systemised wall panels are installed after the frame is completed.
Step 3
Once safety is assured, fixtures are assembled. The roof, pillars and floor are bolted. Wall panels, glass doors and others are installed. Setup of a single unit can be completed in one hour.
Installation of facilities can be done alongside the construction of the building, cutting down on overall construction time needed.
Step 4

Air-conditioning, electrical wiring, and a switchboard panel are installed. As each unit includes electrical wiring installed in the factory, onsite electrical work simply requires a connector.

*** Construction time may differ according to interior/exterior specifications, site circumstances, etc.

Fast, Efficient and Safe

Our modular products’ finest features – fast, efficient and safe construction. Each unit is transported in a folded state, after which construction (and dismantling) takes just a day. Our team is happy to accommodate to special and urgent requests.

After factory production, the unit will be transported to the site. For more efficient transportation, the unit’s folding feature allows us to transport up to six units at a time. As a result, CO2 emissions can be reduced by about ⅙ compared to traditional construction methods, resulting in more environmentally sustainable practices.

Safety by Construction Procedure

When constructing a multi-storeyed building, setting up stairs instead of a stepladder significantly improves safety at work.

Safety Indoors

Since the installation and maintenance of air conditioning units and electrical wiring can be done onsite, within each unit, no stepladder or working at height is required. In addition, installation of facilities can be done concurrently with the construction of the building, cutting down on time considerably.

Safety during Electrical Wiring Work

By installing electrical wiring in the factory in advance, wiring work is greatly simplified. Onsite, electrical work can be completed simply with a connector, so the construction process is safe.

Safety during High Altitude Work
We take safety measures seriously. By tying the main rope and connecting it to a safety belt, the safety of our workers – even at high altitudes – is assured.
Safety during Crane Operation
By lifting the roof and adopting a “butterfly construction method”, the pillars can automatically be erected. This way, no manual power is needed, resulting in a smaller team. So it’s not just efficient – it’s safe too.
Safety during Maintenance
During maintenance, there is no need to use the stepladder to access the roof from the second or third floor – workers can head to the roof via stairs, which are more stable and safe.
