Urban Development Service (Real Estate) BusinessWe engage in real estate development primarily in the Tokyo metropolitan area through the use of owned land, acquisition of new real estate, and joint ventures with business partners.
Office Rental BusinessTokyo Gas engages in the construction, ownership, and rental management of several buildings mainly in central areas of Tokyo to provide high-quality office spaces. Major projects are as below.
Shinjuku Park Tower
Shiba Park Building
Residential Leasing BusinessWe developed the “LATIERRA” series of rental condominiums, which primarily serve popular urban areas, to offer housing for safe and comfortable living. In May 2018, we began construction on the Toyotama Rental Housing (provisional name) as our first medium-scale project on land owned by Tokyo Gas, and we acquired four new buildings for rental housing during the fiscal year.

SEN in the Northern District Adjacent to Tamachi Staion's East ExitThe Tokyo Gas Group has been collaborating with Minato Ward in Tokyo to develop a low-carbon, disaster-resilient community in the northern district adjacent to the east exit of Tamachi Station. The project is intended to optimize energy demand, save energy and enhance disaster resilience by building a SEN. In 2014, construction of the Block I Smart Energy Center was completed and began supplying heat and electricity to the Minato Park Shibaura, a hospital and child welfare facility in the Life Zone. In May 2018, the Block II Smart Energy Center began operations within the New Urban Zone and started supplying energy to office buildings and a hotel. This public-private project is also intended to optimize energy management across the entire area by having the two SENs supply heat to each other, thereby reducing CO2 emissions by 30% below 2005 levels.

SEN Development in the Toyosu Wharf DistrictThe Tokyo Gas Group is pursuing urban development with the potential to extend deep into the 22nd century in a redevelopment area located around land the Group holds in the Toyosu wharf district of Tokyo’s Koto Ward. Under this project, “Tokyo Smart City TOYOSU 22,” we are undertaking futuristic urban development guided by the three concepts—“smart energy,” “smart green,” and “smart community,”—from a long-term perspective looking beyond the Tokyo 2020 Olympics and Paralympics, as a high-quality development to raise the value and appeal of the area.
■TOYOSU 22 Urban Development Concept
In May 2016, we completed construction of a smart energy center in Zone 4 (see figure below), owned by Tokyo Gas Real Estate Co., Ltd., in preparation for development of a SEN in the Toyosu wharf district. This is the second SEN to be developed by Tokyo Gas in an urban redevelopment district, following the Tamachi SEN. The newly completed smart energy center is equipped with one of the world’s most efficient CHP systems, which supplies electric power to the Toyosu wholesale market while using its exhaust heat to power equipment at the center. Environmental friendliness has been enhanced by adopting gas pressure differential power generation*1. By applying CHP systems with blackout start specifications*2 to construct the systems, laying independent power lines*3 and employing disaster-resistant medium-pressure gas pipelines, we have created a system capable of an uninterrupted supply of heat and electricity, even during power outages or other emergencies, thus enhancing the district’s resilience to disaster. The network also has a “SENEMS”*4 for centrally managing and controlling energy throughout the district using ICT. SENEMS will instantly analyze and process real-time information on supply and demand, weather conditions and specific characteristics associated with each day of the week in order to automatically optimize energy demand and supply for the area. We plan to progressively expand the heat and power network as the development of Zones 4 and 2 progresses.

Kiyohara Smart Energy CenterIn October 2016, Tokyo Gas and Tokyo Gas Engineering Solutions Corporation began constructing the Kiyohara Smart Energy Center. This is based on a large-scale CHP system that will supply electricity and heat in the form of steam and hot water to seven plants operated by three companies in the Kiyohara Industrial Complex on the outskirts of Utsunomiya City in Tochigi Prefecture.

Participation in Yokohama’s Tsunashima-Higashi Smart Town ProjectThe Tokyo Gas Group is pursuing a number of projects, including development of an energy center, in Tsunashima Sustainable Smart Town, a next-generation urban smart city that will be developed on the former site of a Panasonic factory in the Tsunashima-Higashi district of Kohoku Ward in Yokohama, Kanagawa Prefecture.
