The Product is Made in Japan.

We produce well-designed shelters.

Japan frequently experiences natural disasters such as earthquakes and tsunamis. Underground shelters are highly effective in protecting lives from these threats and serving as storage spaces for emergency supplies. However, their adoption rate remains low compared to countries like Switzerland and Israel, highlighting the need for further safety measures.

In particular, ventilation systems are essential for maintaining health during evacuation, as they provide fresh air and enable long-term sheltering. We are committed to offering high-quality, affordable ventilation systems to help establish safe evacuation environments.

By raising public awareness of disaster preparedness and promoting the construction of underground shelters and infrastructure, we can work together to build a safer future.

Ventilation System

One of the most crucial elements in constructing underground shelters is the ventilation system. Currently, there are no domestically manufactured ventilation systems available, forcing reliance on expensive foreign products. We will manufacture and sell safe, high-quality ventilation systems domestically.

Underground Shelter Construction

Based on the standards set by the Japan Nuclear Shelter Association, we will construct underground shelters that are safe, secure, and designed with unconventional aesthetics. We aim to promote their widespread adoption throughout Japan.
