Tokyo Gas in Numbers

As of September, 2019

For 130 years we have been at the forefront of energy.

Established 1885
Introduction of LNG 50years ago

History of More than 130 Years

Established in 1885, Tokyo Gas has been constantly meeting new challenges as a pioneer in the field of energy for more than 130 years.
Coal gas was supplied when the company was first founded up until 1952 when petroleum gas started to be used. Eventually liquefied natural gas (LNG) was introduced as petroleum gas was unable to adapt to the growing energy demands of Japan and LNG was seen to be a clean energy fuel that didn't emit sulfur oxides (SOx) when burned and produced less nitrogen oxides (NOx) and carbon dioxide (CO2) compared to petroleum gas.
Thus, Tokyo Gas procured LNG for the first time in Japan in 1969. For half a century since then, the company has supported economic development and comfortable living in Japan through the stable supply of gas. Our technological and maintenance know-how on the production and supply of LNG built up during this time as well as our domestic and international network spanning procurement to sale and the trust of our customers - these things are our valuable assets.

We participate in the entire value chain from the procurement of LNG to regasification, supply and sales, and we also provide energy solutions. Using our rich knowledge and credible track record to our advantage, we will continue to develop our energy business both in Japan and around the world.

Procuring LNG from 14 Projects in 6 Countries

In order to procure LNG in a stable manner, we have 14 long-term contracts with projects located mainly in Southeast Asia, Australia, Russia (Sakhalin) and the US. Moreover, we are diversifying our procurement by collaborating with a variety of players in Japan and abroad so that our procurement can be price-competitive and flexible to adapt to demand fluctuation.

Ownership and Management of 13 LNG Carriers

Tokyo Gas Group owns its own LNG carriers. By operating our own carriers, we aim to reduce costs and promote the diversification and expansion of suppliers. In addition, we strive to ensure that there will be no obstacles in the procurement of LNG even when geopolitical risks such as disasters and conflicts arise, by conducting stable transport of LNG through efficient operation of vessels.

4 LNG Terminals

LNG is brought to four different LNG terminals in the Tokyo metropolitan area for the stable production and supply of city gas.
The storage capacity amounts to 3,470,000 kl. The construction of a second tank has begun at the Hitachi terminal in anticipation of growing demand for natural gas. We are aiming for a launch date in fiscal 2020.

High-Efficiency Power Generation Business

We operate high-efficiency natural gas thermal power plants using natural gas produced at LNG terminals as fuel. Moreover, as a global warming countermeasure, we are working towards power generation through renewable energy.
The scale of our power source is approx. 1.6 million kW. We aim to increase this to 3 million kW by fiscal 2020 and to 5 million kW during the 2020s. We are also actively promoting renewable energy by aiming for 400,000 kW of power source capacity for renewable energy in the first half of the 2020s.

Total Pipeline Length Circles the Earth 1.5 Times

The pipeline network of Tokyo Gas centers on the Tokyo metropolitan network and has a length of more than 60,000 km, which is 1.5 times the Earth's circumference. In addition to systematically replacing aged cast iron pipes to prevent gas leakages and in anticipation of natural disasters such as earthquakes, patrols are implemented at high-pressure gas transport lines. Moreover, the status of city gas production and transport is monitored and controlled at the supply command center 24 hours a day, 365 days a year.

Supplying Gas with LNG Lorries and Satellite Stations

Gas is supplied with the more than 190 LNG lorries in areas where gas pipes have not been established. These account for one quarter of all LNG lorries in Japan, making Tokyo Gas the leader in terms of scale and performance in LNG lorry supply. We also construct satellite stations at which LNG is treated in order to supply natural gas to factories of clients and areas where extension of existing gas pipes is difficult.

Sales and Energy Solutions

Providing Energy-Saving and Low-CO2 Solutions

Tokyo Gas uses the technological strength and know-how accumulated in its LNG value chain for over half a century to provide diversified energy systems such as gas cogeneration systems which help to save energy, cut CO2 emissions and cut power peaks, solutions like local heating and cooling, energy services, smart energy networks and “smart multi” systems that save energy through optimal control of gas and electric power.

Answering Demand from 11.8 million customers

In 1955 Tokyo Gas had 1 million customers. By 2007, this figure surpassed 10 million and today it stands at 11.8 million. At the 180 branches of Tokyo Gas Lifeval, Enesta and Enefit, about 14,000 staff work to meet the detailed needs of each and every one of our customers as representatives of Tokyo Gas in their respective regions.

Sales volume of Electricity: 15.5 billion kWh

Tokyo Gas launched its electric power business in 2000. With the full liberalization of electric power retailing in fiscal 2016, we have expanded our sales to include household and business customers in addition to wholesaling. We are currently selling approximately 15.5 billion kWh of electricity and plan to expand our sales volume to 31 billion kWh in fiscal 2020. We will expand our electric power business by providing value such as profitability, safety, simplicity and convenience to customers in pursuing enhancement of corporate value.

Number of Electricity Retail Customers : 2 million

With the liberalization of electric power retailing in April 2016 and the subsequent liberalization of city gas retailing in April 2017, the Japanese energy market has become fully liberalized. The number of electric retail customers of Tokyo Gas rose quickly to exceed 2 million by August 2019, making it the company with the largest market share in the low-voltage power field among new electric power companies. We will continue to not only sell energy such as gas and electric power but also provide new value and services that enrich the lives of our customers.

We use our accumulated experience regarding LNG value chains in Japan and abroad to develop operations overseas actively from upstream to downstream businesses.

Overseas hubs 9countries
Main projects 22projects

North America, Australia and Southeast Asia

The Tokyo Gas Group has 13 overseas hubs in 9 countries, namely the US, Australia, France, Singapore, Thailand, Indonesia, Vietnam, Philippines and Malaysia.
In North America where energy demand is high and long-term growth is anticipated for the natural gas market, we have joined gas development projects and are engaged in gas thermal power generation and energy service projects as the market is being liberalized and energy market transactions are developing.
In Australia which has achieved growth as a major supplier of LNG to East Asia, we are focusing on operation/management of the five LNG projects that we own.
We are working in collaboration with governments and corporations in Southeast Asia where demand for natural gas is expected to grow, engaging in midstream to downstream projects for terminals for receiving LNG, gas thermal power generation, gas distribution, energy services and such in an aim to develop an energy chain in these countries.

As a lifeline for citizens and infrastructure for industrial activity, what's most important for our business is safe and secure supply and the trust of our customers in the Tokyo Gas brand.

Seismometers 4,000units
Emergency security experts 600persons

Automatic Shutdown of Gas Supply with Seismometers

Seismometers have been established on all governors (pressure regulators) in approximately 4,000 locations in the supply zones of Tokyo Gas in the event of an earthquake. The supply of gas is automatically cut off when a large earthquake is detected. There is about one seismometer per 1 km2, a density not found anywhere else in the world.

Emergency Dispatch System Ready
24 Hours a Day, 365 Days a Year

Once a gas leak is reported by a customer and the person in charge of the safety command center (base of command) has a clear understanding of the situation, security experts from the service area's some 50 “Gaslight 24” bases rush to the scene. These experts are ready to be dispatched 24 hours a day, 365 days a year, in the event of an emergency situation.
