Introduction

Natural gas is expected to play an important role in the realization of a low-carbon
society with its environmentally friendliness, with shifting to natural gas being clearly
indicated in the national Basic Energy Plan. It addition, natural gas offers high supply
stability because of its diversified supply source and strong value chain. It is also an
economical and user-friendly energy source which has the ability to cope with such
diversified demands as on-site power generation. Backed by these benefits, we can
foresee no change in its superiority and importance, and expect the needs for this source
of energy to continue expanding among both individual customers and societies.

Meanwhile, we are observing the emergence of changes in our business climate that
could exert a major impact on the execution of the Tokyo Gas Group’s Integrated Energy
Business Strategy. These changes include intensified energy competition among energy
sources including electricity, and changes in the conditions surrounding gas resource
procurement due to the steep rise in crude oil prices, and the rise in global energy
demands of mainly emerging countries.

In January 2009, the medium-term Group management plan for FY2009-2013 was
prepared with the objectives to respond to these changes in the business environment
both promptly and appropriately, and to more vigorously promote our Integrated
Energy Business Strategy. The management plan also calls for steps to strengthen the
LNG value chain and reinforce the synergy of "All Tokyo Gas"* in order to achieve these
goals.

Through action on this agenda, we desire to simultaneously further the penetration and
expansion of natural gas use based on even higher levels of added value, while widening
and deepening Group business in the energy field, so that we will be able to respond
flexibly to future changes in the business climate and to achieve sustainable growth.

The effects of the 2011 Tohoku-Pacific Ocean Earthquake are not yet incorporated in
these supply plans.

* All Tokyo Gas is a collective term for Tokyo Gas Co., Ltd., its affiliated companies, and
its cooperating companies.

1. Gas penetration plan

For the next 5 years, the average number of newly connected customers is expected to
be about 180,000/ year. We foresee an average annual growth rate of 1.0 percent in our
customer base over the next five years, projecting a customer base of 10.984 million by
the end of FY2015.

(Unit: thousand customers)
FY2010 outlook FY2011 FY2012 FY2013 FY2014 FY2015 CAGR (2010-2015)
Number of new customers 170 173 181 184 183 179 1.0%
Total number of customers 10,440 10,552 10,661 10,771 10,881 10,984 1.0%
* Total number of customers = number of gas meters installed

2. Gas sales volume plan

In observing the gradual recovery of the economy, the plan foresees the total gas sales
volume of Tokyo Gas in FY2011 to exceed that of FY2010, and the expected sales volume
for FY2012 and subsequent years to gradually grow mainly in the industrial sector as a
result of steady economic growth and the increasing awareness in environmental issues.
As a result, we expect the total gas sales volume of the company to reach about 15.2
billion m3 in FY2015. As a result, the projected average annual growth rate over the
five-year period would be projected at 2.7 percent.

(Unit: Million m3; 45MJ/m3)
FY2010 outlook FY2011 FY2012 FY2013 FY2014 FY2015 CAGR
Total gas sales volume 13,271 13,371 13,772 14,307 14,801 15,186 2.7%
* Figures for FY2010 are projections following standardization (correction for
temperature in the formulation of FY2011 plans and those for subsequent years). Note
that this also applies to these figures for the rest of this document.

(1) Residential demand

In this sector, the amount of sales per customer is in decline due to such factors as the
reduction in the number of family members per household, a rise in the share of
collective residential properties with high levels of air tightness and insulation, and the
penetration of high-efficiency gas equipment. The trend of excess population influx into
the Tokyo metropolitan area is expected to moderately continue, and the company is
committed to efforts for the cultivation of new demand and the penetration and
expansion of its leading edge equipment and systems. The company is expecting its
residential gas sales volume in FY2015 to be 3.4 billion m3.

Gas sales volume per customer 385 381 378 376 374 372 ▲0.7%

(2) Industrial demand

This sector accounts for the largest share of the total gas sales of the company. The sales
volume in this sector is expected to grow as a result of the development of large-lot
demands for the expansion of our business to a wider area, and the shift from other
fuels due to the effects of national energy policy. For these reasons, the company is
expecting its FY2015 industrial gas sales volume to be 6.8 billion m3.

【Industrial gas sales volume】

4. Major facility plan

Tokyo Gas will improve and reinforce its production and supply infrastructure to more
accurately respond to its projected gas demands.

We plan to complete the Shin-Negishi Trunk Line (Yokohama City), the 2nd Phase of
the Yokohama Trunk Line (Yokohama City – Kawasaki City), the Chiba – Kashima
Trunk Line (Chiba City – Kamisu City), and the Saito Trunk Line (Soka City – Koga
City) to offer even greater stability of our supply systems in order to meet increases in
future demand.

The plans also call for the installation of vaporizers in the three terminals located on
Tokyo Bay and the construction of the No.4 LNG tank in the Ohgishima Terminal.

In addition, Tokyo Gas will respond to the natural gas expectations and needs of its
customers and society as a whole over the medium and long term, while further
solidifying its foundations for a stable supply. To this end, Tokyo Gas will promote the
early execution of construction plans for an LNG terminal in the Hitachi District of
Ibaraki Port and the Ibaraki – Tochigi Trunk Line to connect the area to its existing
pipeline network.
