“GURA-SAFE”
The Wooden Shelter
for Earthquake & FireThe world's first "wooden earthquake & fire-resistant shelter" (one-hour fireresistant structure), which is resistant to collapse of houses, earthquakes, andfires, was born with our unique Cell-Funen technology.
In the unlikely event of an earthquake, not only human lives but also "importantmemories" wll be firmly guarded.
Installation work can be done while living at home, and termites and mold canbe shut out.

“GURA-SAFE”

Engineered byJapan Technology

The Wooden Shelter
for Earthquake & FireThe world's first * wooden earthquake-resistant and fire-resistant shelter, which is resistant to the collapseof houses and disasters caused by huge earthquakes, was born with its own non-combustible technology.
It can be installed on the premises while living in your own home. (* our company’s research)■Special Features:
1. Seismic resistance: Seismic resistance confirmed not to collapse even in experiments that reproduced
the actual earthquake motions of Japanese biggest disaster in 2011.
2. Fire resistance: Ensuring 1-hour fire resistance at 1000˚C using our patented “Cell-Funen technology
for non-combustible material.
3. Non-combustible: Not only is it resistant to flames, but it also "does not burn, does not emit smoke or
hazardous gas" to prevent the spread of fire to the surrounding area even in densely populated residentialareas.

Recommended by the Academic Experts
Prof. Shinichi Sugawara (Professor Emeritus, The University of Tokyo / Tokyo University of Science)“Earthquakes are occurring all over Japan, and it is an era that ‘when’ and ‘where’ of a major earthquake’soccurrence is quite unknown.
Previously, the evacuation measures for earthquakes and fires was separated, but now they are to bereconsidered. Also recommended by disaster prevention experts
Under such circumstances, it is highly significant that the disaster prevention shelter "Gura-Safe", which
has both of earthquake resistance and fire resistance was born.
And what I would like to pay more attention is that it is made of non-combustible wood.
In a situation that tends to be mentally unstable, a shelter space made of wood, which has been familiar tothe people for a long time, will give users a sense of comfort and security.”

In a heating test of 1,000˚C for 1 hour according to ISO standards, even if the external temperature reaches
1,000 ˚ C, the indoor temperature rises by about 4 ˚ C with respect to the outside temperature
at the maximum (+0˚C specifications are also available). It has fire prevention performance that protects
property from flames of 1,000˚C.

Inside the furnace during thefire resistance test.
The temperature inside thefurnace is 1,000˚C and the redcolor is the refractory LVL of theexternal surface material.

Fireproof LVL of externalsurface material after fireresistance test at 1,000˚Cfor 1 hour. The surface iscarbonized.

Due to the performanceof the fireproof structurewith an external surface
material thickness of 50mm, the seismic structuralmembers are not affected.

■Seismic / Vibration Test
The disaster prevention shelter "Gura-Safe" was placed on a large three-dimensional shaking table to reproduce theactual seismic waves. (At Japanese Public Works Research Institute)
As a result of fixing the acceleration converter to the bottom of the shaking table and the roof of "Gura-Safe" andrecording the acceleration data during vibration, the correlation function of the displacement waveform of the shaking
table and "Gura-Safe" is very similar. It was confirmed that there were no cracks or damage.

Installed on a shaking table“Great Hanshin-Awaji Earthquake” in 1995

“Great East Japan Earthquake” in 2011

“Kumamoto Earthquake” in 2016

Even at the three major earthquakes in recent
years reproduction in the test succession,
there was no damage inside or outside the"Gura-Safe".
It has been proven to withstand and have arobust resistance to the Mega-Earthquakes
actually happened in Japan;“Great Hanshin-Awaji Earthquake” in 1995
“Great East Japan Earthquake” in 2011 and“Kumamoto Earthquake” in 2016
they were unprecedented disasters above
Japanese Magnitude 7.
