Solar Power System on the Tokaido Line Platform at Tokyo Station to Begin Operation
East Japan Railway Company
February 25, 2011
Pursuant to the "JR East 2020 Vision –idomu-", the JR East Group is engaging in measures to prevent global warming. As part of these measures, construction that began in January 2010 to install a solar power system on the Tokaido Line platform (tracks 9 and 10) at Tokyo Station was recently completed, and the decision was made to begin utilization of the system on February 25, 2011.
Solar power systems had already been introduced to JR East stations on the Shinkansen Line platform at Tokyo Station and at Takasaki Station. The recently introduced system, however, is our largest on the scale of power generation with a projected capacity of 453 kW, annual generated output of approximately 340 MWh, and a CO2 reduction effect of approximately 101 t. This corresponds to approximately 0.3% of the total electric power used by Tokyo Station as a whole.
The generated electricity will be used to power Tokyo Station lighting, air conditioning, and so on. JR East will continue to pursue the adoption of energy-saving measures and will implement further CO2 reductions.

| (2) | Annual power generated and CO2 reduction effect (projected) |
| Item | Effect of panel introduction | All of Tokyo Station (percentage contributed) |
Annual power generated |
Approx. 340 MWh/year |
Approx. 98,000 MWh/year (approx. 0.3%) |
CO2 reduction effect |
Approx. 101 t/year |
Approx. 25,700 t/year (approx. 0.3%) |
| * | When converted, this CO2 reduction effect is equivalent to the planting of approximately 7,214 cedar (sugi) trees. |

2. Miscellaneous
| (1) | The status of power generation by these solar panels can be viewed in real time on power generation output display monitors installed at four locations within Tokyo Station.
|
| (2) | This solar power system was introduced as a joint project with Chiyoda Ward. |
| (3) | The project has received a Grant in Aid for Promoting Regional New Energy and Related Technology Adoption from the New Energy Promotion Council. |
