Kagoshima Prefecture is a unique prefecture that has many isolated islands that stretch about 600km north to south, with the active volcano Sakurajima as its symbol. Volcanic ash in the central area, salt damage in the remote islands, and sulfur in the hot spring area make it an unfavorable environment for steel LP gas containers. We are working hard every day to make sure you can use it. In addition, LP gas is also used as fuel for taxis and forklifts, and large containers and storage tanks are installed in stores and apartment complexes, and lorries are used for transportation. Various containers and storage tanks are used to use LP gas. Is required. We are working hard to face each and every one of them and continue to be safe and secure. Furthermore, LP gas is expected to spread in Southeast Asian countries and African countries in the future, and we would like to provide reliable partners with the technology and experience of Japanese container inspection. And as the movement toward a decarbonized society becomes more active worldwide, we will make use of our many years of experience in inspections to launch new initiatives such as inspections of structures using drones and inspections of hydrogen containers for fuel cell vehicles. started.
