Environmental Initiatives

Basic Philosophy

In the Group Vision, the Seibu Group declares its commitment to contributing to the development of local communities and society at large, and to preserving the natural environment and to be mindful of the natural and global environment. For the Seibu Group, which operates an array of businesses closely embedded in local communities and society, including railways and hotels, business activities that pay attention to the natural environment and to communities are an utmost priority. In addition to working to protect the environment, including air and water resources, we will proactively communicate with stakeholders to become a corporate Group that is a trusted member of the local community and society as we achieve sustainable growth.

The Seibu Group's Initiatives Expressed in Numbers

Initiatives Taken by Group Companies

Efforts to Save Energy by Seibu Railway and Seibu Bus

Low-pollution vehicles compliant with environmental standards

We store the regenerative electric power produced when a train conductor applies the brakes in power-storage-type regenerated power absorbers installed in substations located in Tanashi, Shomaru and Agano. This energy is later used to power trains. We have also installed in-station powerstorage-type regenerated power absorbers in Ikebukuro, Iruma shi, and Hon-Kawagoe stations and save energy by using regenerative electric power for station facilities (such as lighting, air conditioning, and elevators). Seibu Bus introduced hybrid fixed-route buses in 2008 and this improved fuel efficiency by 20-30% compared with gasoline-only buses. The Company's gasoline only buses have also been upgraded to low-emission vehicles that meet environmental standards and produce fewer toxic emissions than previous models.

Tokyo Garden Terrace Kioicho in Harmony with Its Surroundings and Nature

Releasing freshwater snails

In addition to being an important historical property, based on the principle of being in harmony with its surroundings and nature, Tokyo Garden Terrace Kioicho proactively participates in a wide range of activities in the area, thereby strengthening ties with the people who live there. The building sits on roughly 30,000 square meters of land, roughly 45% of which has been converted to green space. We are working to maintain and protect the natural environment of the land and foster a biotope that allows a wide range of native plants and animals to inherit the area's natural ecosystem. Most of the plants on the land are native to the Tama River ecosystem and we plan to selectively plant and raise plants that are well suited to the area and thereby encourage biodiversity on the property.

Promoting Development of Natural Energy

Prince Energy Eco Farm Karuizawa power plant watermill

As one of the Seibu Group's initiatives to build a long-term foundation for our businesses by using our management resources efficiently, we have found many ways to make effective use of solar power. The Group operates solar power generation facilities in eight locations around Japan that generate 12.44 million kilowatt hours per year, enough to power roughly 3,470 homes. In 2016, a full-scale renovation of the hydroelectric power plant in Karuizawa was conducted and the facilities were reopened under the name Prince Energy Eco Farm Karuizawa. This renovation is expected to reduce annual carbon dioxide output by approximately 731 tons (the same impact as planting 52,214 Japanese cedar trees).
