Projects along Seibu Railway lines

Emio (in-station retail) developments

Emio is the brand of Seibu Eki-naka (in-station) retail facilities. Our first project started back in 2007 at Nerima station, to create and increase value of the life-style of commuters and customers using the station. We have successfully transformed 16 station retails into Emio packages, and on-going. Emio concept is based on Seibu Group Slogan, “Smiles Ahead.” We want our customers to be happy using our station facilities, and become royal fan of the whole Seibu system. The goal of Emio is transforming the stations from transit facility into destinations that are desirable, enjoyable, and reliable for the customers, creating bustle to the communities.
