Company information
Our company has steadily sustained and developed its business under the corporate motto of "contributing to society through our business," primarily renting logistics equipment centered around pallets, which are used for loading cargo in logistics sites, to manufacturers, warehouse companies, logistics operators, and others. In addition, aiming to become a "Social Sharing Supporter" that tackles all challenges surrounding logistics, which is essential for maintaining people's livelihoods, we are not only further developing our existing business but also creating new businesses, expanding our logistics and connected services. In modern society, as lifestyles diversify with a shift from "ownership to usage" and from "consumption of goods to consumption of experiences," and with labor shortages becoming prominent due to "declining birth rates and an aging population," the social structure is changing. The emergence of the COVID-19 pandemic has significantly altered the social environment, increasing the demand for non-contact solutions that do not require human intervention. In response to these changes, our company is actively utilizing digital transformation (DX) to promote corporate transformation and will continue to work on developing new solutions that are needed by our customers.
