Office Buildings

By utilizing the advantage of being in good locations, Tosei plans and develops office buildings based on the concept that best matches local characteristics. Besides creating stylish exterior and functional work space, we now promote the development of environmentally conscious office buildings that reduce environmental burdens.

	Toranomon Tosei Building A two-minute walk from Kamiyacho Station and nine minutes from Toranomon Station, the Toranomon Tosei Building is a new office building development in which we took full advantage of our knowledge and experience in increasing the value of older office buildings. We created a highly aesthetic exterior design by installing glass curtain walls and the latest utilities and machinery. In addition to rooftop greenery, the environmentally conscious design includes energy-saving features such as insulating glass, which improves heating and cooling efficiency.
	Kanda Ogawamachi Tosei Building II Facing Yasukuni Street, Kanda Ogawamachi Tosei Building II is a commercial and office complex which makes the most of its convenient location near stations including five subway lines and a JR line. The facade with a stylish glass wall creates an impressive look. Book stores and sporting good stores are in the neighborhood and enhance its convenience.
	Kamata Tosei Building Kamata Tosei Building, conveniently located three- minutes on foot to JR Kamata station. Following Heiwajima Tosei Building, Kamata Tosei Building is the second property Tosei acquired a CASBEE Rating for. Considering harmony with the surrounding environment, its design well-united with streets, reduction in heat load by using low emissivity coated glass as well as reducing energy use by introducing high efficiency lighting have been highly valued. CASBEE stands for Comprehensive Assessment System for Built Environmental Efficiency, a method for assessing and rating the environmental friendliness of buildings, it has been gaining attention.

Commercial Facilities

T’S BRIGHTIA is Tosei’s corporate brand for commercial facilities. Based on the concept of creating space to brighten up the minds of both residents and visitors while taking advantage of the characteristics of towns, Tosei has been providing highly original commercial space in convenient areas near stations in the 23 wards of Tokyo, attracting quality tenants.

	T'S BRIGHTIA Kichijoji We developed this commercial facility with a focus on "MONOZUKURI". It is located in a good neighborhood, just a three-minute walk from Kichijoji Station on the Chuo Line. We welcomed the American casual brand for a specious-glass-walled-bright tenant space, and the building is now in the spotlight as a new Kitchijoji shopping venue.
	Shinjuku Building With the Shinjuku Building project, Tosei Corporation's first commercial facility development, we took full advantage of the property's excellent location. It is only a one-minute walk from the south exit of Shinjuku Station. The meticulously designed exterior looks like a glass box, and a black monotone interior was chosen to evoke the image of an art gallery. The tenant we attracted, a jewelry shop, was featured in the press and magazines and has become the talk of the town.
