| Point 1 |
| This method was developed in Nagano, Japan, an area known for its heavy snow. |
 Hokusei’s use of SWT blocks has been certified by the Building Center of Japan (BCJ*). In Japan, the strength of the structure meets all requirements for the strength levels to build a three storey home in heavy snow regions.
 In Japan, the value of this Japanese certificate and standard building laws minimizes the amount of paperwork and permits required during the process of building authorization.

* BCJ - The Building Center of Japan
The BCJ consists of a group of highly experienced members and serves as an incubator for new building technologies. It performs a wide range of activities, including evaluation, research, and development of new building technologies. |

| Point 2 |
| The fracture point of the Hokusei SWT method is 2000kgs with 16mm support bolts, and 4000kgs with 19mm high-strength bolts. |
 In fact, during the 4000 kg testing, the pressure does not compress the SWT blocks, but rather only the base part showed evidence of fracturing. This illustrates the amazing strength of this method using the SWT blocks.
This is incredibly strong when one compares this to the fracture point using ordinary wood construction which is 700 ~ 800kgs and the fracture point of 2x4 construction method which is 1600kgs.
